Jamstec used to have a lot of information on their website but much of it seems to have left after a reported breach a couple of years back. I find this type of study fascinating. ET. 2021 Associated Newspapers Limited. And we can expect plenty of it this winter, according to the Farmers' Almanac, which recently released its 2022-23 Extended Weather Forecast. So, next, we want to know if there are any consistent differences in the sea surface temperature pattern between La Nias that lead to wet versus dry early winters in the Southwest. The rest of the United States shows less snowfall than normal, but that does not mean no snow at all. Heres what that means. But otherwise, the rest of the continent shows less snowfall than normal for this month. by Craig T, Regardless of the cause, the above normal rainfall for Tucson this winter is unusual during a LaNina event. Below, you can see the progress of some historical multi-year La Nina episodes, with only two events previously having a 3rd-year event. Sunshine and showers on Sunday. A large swath of the country, from the East Coast down into the Sun Belt and into the Mountain West, is projected to experience above-normal temperatures, with the highest probability of abnormal warmth in Arizona and New Mexico. But what's the long-range outlook for the next three months? The data shows that the La Nina jet stream pattern also changes the snowfall patterns over North America as the pressure systems take a different path, along with the cold air. Northerly winds (i.e. January 2022 in Iowa was 4.8 degrees colder than average. However, we still need more analysis to see if the particular sea surface temperature pattern this year played some role, including the unusual frequency of atmospheric rivers. Reporting on Earths changing climate and the people trying to find solutions to one of the biggest challenges of our era. Instead, the pattern looked a bit more like the positive phase of the Pacific Meridional Mode. Drier-than-average conditions are forecast in portions of California, the Southwest, the southern Rockies, southern Plains, Gulf Coast and much of the Southeast. The pattern in the map is very weak, with very small departures between the two groups. Support your business with world-leading science and technology. (Please understand we are not monitoring the blog 24/7.). Fortunately, right on cue, the Farmers' Almanac has released its 2022/2023 winter weather forecast. Drought conditions are now present across approximately 59% of the country, but parts of the Western U.S and southern Great Plains will continue to be the hardest hit this winter, said Jon Gottschalck, chief, Operational Prediction Branch, NOAAs Climate Prediction Center. It says that temperatures there could drop 4 degrees below normal for the month something that could result in a damaged citrus crop and stunned iguanas. The 2022-2023 U.S. Winter Outlook map for precipitation shows wetter-than-average conditions are most likely in western Alaska, the Pacific Northwest, northern Rockies, Great Lakes and Ohio Valley. Submitted by Nathaniel.Johnson on Fri, 02/24/2023 - 16:47, In reply to DEC/JAN 2022-23 Southwest U.S. Could the jet stream also have influenced precipitation amounts ? So what's in store? But if these big picture findings hold up to further scrutiny, then it means that the typical or averaged La Nia precipitation pattern still may be the most reliable guide for seasonal predictions of Southwest precipitation in early winter, but we may have to rely on subseasonal and weather forecasts rather than seasonal outlooks to anticipate the sort of soaking that occurred in December and January of this winter. Below-average temperatures are forecast in the northern contiguous United States, stretching from northern Michigan to northern Washington state. I'm surprised that this is only the second La Nina winter with above-normal rainfall, but this document seems to support that claim (two of the "weak" episodes in the table with above-normal rainfall were not classified as La Nina by CPC). The December snow depth forecast shows widespread negative anomalies. NOAA Climate.gov image, based on analysis and data provided by the Climate Mapper website. Distribution of DecemberJanuary precipitation anomalies (percent of the 1991-2020 climatology) in the Southwest U.S. (region defined in the figure above) for all 21 La Nias from 1951-2020. Comments are placed in moderation and must be approved by a blogger before they are posted. Because the observed record is too short to tease out the relationships we seek with sufficient precision, we rely on climate models to sharpen the signal relative to the noise of random weather variability. NOAAs Precipitation Reconstruction over Land (PREC/L). La Nia could enter rare third straight year. Who we are, what we do and organisational news. For the first three months when winterlike conditions begin in earnest November, December and January abnormal cold is not expected anywhere in the country. Colorado Avalanche Information Center forecasters need intricate knowledge of snowy layers that sit below the surface as they warn public of hazards and risks. Most of Europe is forecast to have less snow depth by mid-winter. Often with the cold easterly winds, and the air travelling over so much dry land, there is very little moisture in it to form the snow and we end up with some crisp winter sunshine instead. Probably the coupling of weak Polar vortex with the recurrent PV stratospheric warming has something to do with the Southward (equator-wise) migration of Atmospheric wet Rivers in mid to late winter , this last point is well-documented in many physical science papers that weak polar vortex post SSW events tend to measure more equator-wise migration of the Jetstream causing these atmospheric rivers to bring wetter than normal events to California and many mediterranean-like climates in the northern hemisphere late winter. (NOAA) This figure indicates that SPEAR produces very wet early winter conditions in the Southwest for some of the La Nia simulations, with the largest differences between the wet and dry groups exceeding twice the 1991-2020 climatology (more than 200%). If youre wondering what sort of calculations led to this conclusion, then I will give you all the details here. This figure confirms that SPEAR simulates very high Southwest U.S. precipitation totals in December-January in at least some of the simulated winter La Nias. Above-normal precipitation is possible in northwestern Montana, northern Idaho and northeastern Washington state. Submitted by Nathaniel.Johnson on Thu, 03/02/2023 - 09:50, In reply to Other teleconnections by Stan Rose. Regarding the "warm blobs" you mention, most studies suggest that extratropical sea surface temperature anomalies generally do not have a major impact on the large-scale atmospheric circulation, so I suspect that the two warm blobs you mention did not have a major impact on Southwest U.S. precipitation. With temperatures so warm winter and the chance of snow feel somewhat distant. In the SPEAR simulations, I examined the relationship between the ensemble mean Southwest U.S. precipitation anomalies and the La Nina SST anomalies. This results in 21 values covering all historical La Nias during the period for which the noise of chaotic weather variability has been largely averaged out. I saw this same behavior in my analysis of the SPEAR climate model simulations, which increases confidence that this more robust dry signal in February-March is a real phenomenon. NOAAs Climate Prediction Center updates the three-month outlook each month. A blog about monitoring and forecasting El Nio, La Nia, and their impacts. We see more snowfall over the northwestern and northern United States and southern Canada. One of the main points of this post is that it's difficult to rule out the role of chaotic atmospheric variability that is unrelated to the underlying sea surface temperatures when it comes to unusual Southwest U.S. precipitation. Resources such as drought.gov and climate.gov provide comprehensive tools to better understand and plan for climate-driven hazards. We first have to take a quick look at the leading global weather driver for the upcoming winter season, La Nina. Minimum temperature 2C. This does not mean there will be no snow, but it indicates less snowfall than normal. Meet COP21 Education Ambassador Shannon Bartholomew! Also, the southwest is expected to be dry during the winter months, which won't help the drought. Conditions will be particularly cold through the middle of the month, with widespread frosts and a risk of wintry showers, even to low levels in some cases. Want to know how your actions can help make a difference for our planet? NOAA Official precipitation outlook points: Also, we will keep you updated on other developing weather trends, so bookmark our page. The greatest chances for drier-than-average conditions are forecast in portions of California, the Southwest, the southern Rockies, southern Plains, Gulf Coast and much of the Southeast. The hardworking forecasters at NOAAs Climate Prediction Center produce timely and accurate seasonal outlooks and short-term forecasts year-round, said Michael Farrar, Ph.D., director of the National Centers for Environmental Prediction. December 2022 looks stormy and cold nationwide with an active storm pattern developing and hanging around for most of the season over the eastern half of the country." In the Great Lakes region,. Karen S. Haller. My calculation that follows confirms this suspicion. Here is what the Met Office is predicting for the coming weeks. This year La Nia returns for the third consecutive winter, driving warmer-than-average temperatures for the Southwest and along the Gulf Coast and eastern seaboard, according to NOAAs U.S. Winter Outlook released today by the Climate Prediction Center a division of the National Weather Service. Feeling cold. With the observations, I did try setting a higher La Nina amplitude threshold (DJF Nino 3.4 SST anomaly amplitude greater than 1 deg. Sea Surface Temperature AnomalyDecember 2010. The most important ingredients for snowfall are the air being cold enough and a supply of moisture. 16 day. Starting with the seasonal average for Europe, we can see another weak snowfall forecast similar to the ECMWF. This is calculated as the deviation of the 30 ensemble members from the average for each individual La Nia event, and so I wind up with a total of 630 deviations from the ensemble average that capture precipitation variations resulting from the uncertainty in the initial conditions, i.e., chaotic weather variability. Let us know. Submitted by Craig T on Thu, 03/02/2023 - 18:31, In reply to forecast busts by Nathaniel.Johnson, Submitted by Nathaniel.Johnson on Fri, 03/03/2023 - 10:31, Minor correction. A fast moving winter storm will bring a swath of heavy snowfall from North Dakota into northern Missouri beginning this evening. Sign up for the Climate Coach newsletter, in your inbox every Tuesday and Thursday. A lock ( You will see the average snowfall forecast for the meteorological Winter season, covering the December-January-February period. The January snow depth forecast shows a similar pattern of more snowfall from western Canada into the northwestern United States. It shows colder temperature probabilities for most of the northern United States. Confidence remains very low during this period. air travelling from north to the south) bring the air straight from the Arctic and over a cold sea to reach the UK. . However, December may put the brakes on this, with a strong signal for this month to be much cooler than average. Annual and monthly snow totals at MSP Airport since 2011-12. Most Mediterranean-like climates ( like South-West Australia, Cape Canaveral , Chili mid-west, East Mediterranean countries and South California ) were pre-forecast to have drier than normal Early winter but showed wetter Mid-winters and hopefully the rest of the winter will be wetter . Into January and February, the ECMWF maps are predicting temperatures to remain close to average, with no significant anomalies. Winter- It's Coming! By Eva Hagan. Such projections reflect typical conditions that develop during La Nia events, which are associated with an episodic cooling of ocean waters in the tropical Pacific. During this period, the prevailing winds continue to blow from the northwest or northeast. Of course, as with all these predictions, they are just indications of the long-range patterns. South West England weather - Met Office South West England weather South West England Bristol 6 Plymouth 8 Bournemouth 7 Exeter 6 Bath 5 Taunton 6 Barnstaple 6 Camborne 6 Dorchester 6. The February snow depth forecast shows continued increased snowfall potential over the northwestern United States and expanding over western and southern Canada. Difference in DecemberJanuary precipitation anomalies (percent of the 1991-2020 climatology) between the wettest 20% and driest 20% of Southwestern U.S. La Nia outcomes simulated by the GFDL SPEAR climate model. Light winds. For full-year 2023, it plans to expand flying as much as . Thanks for raising some good points! TUCSON, Ariz. (KGUN) March marches in like a lion! The seasonal outlook looks at temperature and precipitation trends between December 2021 through February 2022. Drought improvement in the Southwest continues As of July 26, 2022, over 50% of the contiguous U.S. was in drought, with almost 20% in the two worst categories, extreme and exceptional drought (D3-4), a slight increase since late June. Light winds. CPC Outlook for Winter 2022-23: The overall forecast for West Central and Southwest Florida for the upcoming winter is for a better chance of above normal temperatures and below normal rainfall as can be seen in the Climate Prediction Center Winter Outlook graphics below. Overall, however, the winter season is not predicted to be overly wet. Three events went neutral in the third year, and three phases shifted into an El Nino in the third season. There is an increased chance of above-normal temperatures for the winter season and an increased chance of below-normal precipitation. But, with varying levels of success, they can paint a broad picture of how hot or cold or wet or dry different parts of the country may be compared to average. While their predictions won't delight those who hate changeexpect back-and-forth weather patterns across the countryfor the most part, winter won't be harsh. Reports from . The precipitation anomalies are divided into 10 evenly spaced bins, and the number of La Nia events is totaled for each bin. The Farmers Almanac says conditions in the Upper Midwest will be glacial, and it suggests there will be plenty of snow and chilly conditions for winter lovers to enjoy including the potential for a White Christmas. 2022-2023 California and Southwest Weather Thread Also, CPC data reveals an East Pacific MJO episode in January. Thank you, Clara, for the kind words! Just wanted to Note that not all of the Southwest is receiving Robust Moisture. Overall we still see less snowfall than normal for the first Winter month. The new forecast, issued Aug.18, 2022, is pegged on the thought that La Nia is expected to continue through this winter before fading to near normal water temperatures next spring. Submitted by Tony Arnhold on Thu, 03/02/2023 - 16:38. ), and I have seen that there are a few studies that point to processes around Antarctica that could be contributing. Submitted by Nathaniel.Johnson on Thu, 03/02/2023 - 08:32, Tucson Intl Airport had 1.0 inches of snow today (March 2) bringing season total to 1.5 inches. More snowfall can be seen in parts of the Midwest and the northeastern United States. Regarding whether the increased "waviness" is linked to Arctic amplification, we do not have a scientific consensus on such a link. The million-dollar question for seasonal forecasters and climate scientists alike is whether this unusually wet Southwestern U.S. could have been anticipated more than a few weeks in advance. The Met Office's three-month outlook, for example, suggests this winter is half as likely as usual to be classified as wet. Since the latest forecast data was released in mid-late November, we now also have the March data included, so we can look at some early Spring snowfall potential. Looking at the temperature analysis for the same winters, we can see a cold anomaly under the jet stream in western Canada and the northern United States. Over the coming days, cold Arctic air will descend on the UK like a hoard of shoppers on a clothing store in the Boxing Day sales, plunging us into a period of frigid conditions that may well last right through the middle of December and into the run up to Christmas. Long-Range Weather Forecast for Desert Southwest Annual Weather Summary November 2022 to October 2023 Winter will be warmer than normal, with above-normal precipitation. We will see winds increasing out of the southwest today and tonight 20-30 mph, gusting up to 45-50 . The most dynamic winter weather is usually found between the warm and cold anomalies in the Midwest and the central United States. Plenty of sunshine is expected across the south over the next few days, matching temperatures in St Tropez in southern France. Can MJO interfere with ENSO climate? We'll let you know if/when he does! We always focus on trends and probabilities, but still, variation is key. Understanding what teleconnection patterns we can and cannot predict on these seasonal time scales remains a big research topic. Cold weather to arrive this weekend, bringing wintry showers to Scotland, Nanoplastics now ubiquitous in air, water and soil, says new report. December finally brings the cold. NOAA forecasters, in collaboration with the National Integrated Drought Information System (NIDIS), continue to monitor extreme, ongoing drought conditions that have persisted in the Western U.S. since late 2020, as well as parts of the central U.S. where historic low-water conditions are currently present. Durango Herald 3:40 AM MST on Mar 4, 2023. However, I would not rule out that there could be a minor influence, especially with NEP22A, since those anomalies are in a region that did seem to provide a minor enhancement to Southwest precipitation in the simulations I analyzed. 10 day. The rest of the United States and eastern Canada are expected to see less snowfall in the early spring. This figure indicates that the Southwest December-January precipitation was below the 1991-2020 average in 13 of 21 La Nias during the period. The video below shows the developing cold ocean anomalies in the equatorial Pacific as we head deeper into Fall, boosted by the strong easterly trade winds. The Met Office notes that the UK being an island makes snow far less frequent than in mainland Europe. AccuWeather meteorologists break down which areas will. First is the ECMWF, and then it is the UKMO. Below-normal temperatures are favored from the Pacific Northwest eastward to the western Great Lakes. Under this regime, some areas are likely to remain drier with some sunshine, the best of this across inland areas and in the south and west of the UK. Turning to Slide 5. I confirm from a regional point of view here in Jordan we had terribly dry December-January and the start of February was highlight with torrential rains . Even the wettest December-January event before this year, 1955/56, was drier-than-average in February-March, demonstrating that a wet early winter doesnt necessarily mean a wet late winter. The U.S. Winter Outlook 2022-2023 map for temperature shows the greatest chances for warmer-than-average conditions in western Alaska, and the Central Great Basin and Southwest extending through the Southern Plains. The jet stream is a large and powerful stream of air (wind) at around 8-11km (5-7mi) altitude. Categories Long range / seasonal forecast. From the second half of next week onwards, milder conditions seem likely to push erratically north, with spells of rain and snow likely at times - which could be disruptive in places, at least at first. This set consists of 30 simulations, and since there are 21 winter La Nia events between 1951-2020, I have 30 x 21 = 630 simulations of December-January La Nia conditionsa much larger sample size than if I just relied on the 21 observed La Nia winters. Precipitation-wise, the period from November to January is expected to bring below-average precipitation and thus diminished early-season snow and rain chances in much of the southern half of the country, with the greatest chances of below-normal precipitation forecast from coastal South Carolina and Florida all the way to the shores of far Southern California. It added its 10-day or longer forecasts are only . Thanks, Tom. As we emphasize on the blog, ENSO may tilt the odds toward one outcome or the other, but the forecast is always probabilistic. My question, regarding the un-forecast DEC/JAN 2022-23 is whether the heavy precipitation was contributed to by the unusual presence of warming near and east of the Dateline referred to by NOAA as "warm blob" NEP22A and NEP23A? The rest of the United States is forecast to receive less snowfall than normal this month, with the expectation of the far northeastern United States and parts of the southeast. The MJO certainly can interfere with ENSO, particularly during development of ENSO through the MJO influence on tropical westerly wind bursts. While December was above-average as far as the temperature goes, January was a different story. Submitted by Nathaniel.Johnson on Tue, 02/28/2023 - 15:50. Warmer-than-average temperatures are also favored in the Southeastern U.S. and along the Atlantic coast. What is this gigantic hole that has appeared in the fields of Turkey? An important global weather factor is ENSO. There are many patterns that influence U.S. weather, but only a few have a strong connection to slowly varying (and seasonally predictable) sea surface temperatures. Also, we still seem to be transitioning out of La Nina, which may also have some impact.

Are you Weather-Ready for spring hazards? Submitted by Nathaniel.Johnson on Thu, 02/23/2023 - 17:43. Starting with the seasonal average, we see below-average snowfall over most of Europe, which is indicative of a high-pressure dominant pattern. But we can still see an area of more snowfall potential in the Southeast, which can be a single large event. The storied old journal's extended weather forecast predicts "plenty of snow, rain and mush as well as some record-breaking cold temperatures!

The Met Office has warned that snow may appear across the north and west of the UK as early as 9 November. In the January forecast, there is no real improvement. This will be the 3rd year in arow where the Irrigation systems in thisarea have Very little to NO Water Stored for the Irrigation Season. Although it's several months away yet, a typical La Nia winter in the U.S. brings cold and snow to the Northwest and unusually dry conditions to most of the southern tier of the U.S., according. The winter outlook from WeatherBell Analytics, a weather consulting firm, should put more pep in the step of snow lovers. Also, we have the March snowfall forecast data. How will the Hunga Tonga volcanic eruption play into the forecast? Wetter-than-average conditions are most likely in the Pacific Northwest, the northern Rockies, Great Lakes, and Ohio Valley. (Image credit: Getty images), Video highlights from NOAA's 2022-2023 Winter Outlook that provide seasonal predictions for temperature, precipitation and drought. Enjoy summer while you can, folks because Ontario's 2022 winter weather forecast is shaping up to be a real drag. Minnesota DNR. This is mainly a result of warmer-than-normal temperatures expected in late Winter by UKMO in the south/southwest. I need a storm to track south of me without occluding for once. The latest breakthroughs, research and news from the Met Office. The start of this period is expected to be characterised by winds from the north bringing cold conditions to most areas with widespread frost and ice. The brown bars indicate events with below-average precipitation, and the green bars indicate events with above-average precipitation. Out West, even if temperatures are mild, the predicted above-average precipitation can help to ease the regions drought. The greatest chances for drier-than-average conditions are forecast in portions of California, the Southwest, the southern Rockies, the southern Plains, the Gulf Coast, and much of the Southeast. I am no scientist. I will just add that I only focused on one impact and one particular region (Southwest U.S. precipitation), but it would be interesting to do a more comprehensive analysis of possible distinctions between La Nina flavors in the climate model simulations. We have also produced an image that shows the snowfall forecast change compared to the forecast from the previous month. It also shows some snow scenarios over the eastern and southeastern United States. The more forecast data you can look at, the better idea you can get about the expected weather patterns. The data used to produce these graphics is the latest available at the present time, from mid-November. Hello climate.gov administrator, You always provide in-depth analysis and understanding. As far as ENSO goes the one difference this winter seems to be the east tropical Pacific was not as cold as the prior years when the SSTs in the Nino 1.2 at times were from -2 to -.2.5 while the western tropical pacific was near neutral. Historically, a strong blocking high-pressure system in the North Pacific is the most typical effect of a cold ENSO phase. Widespread extreme drought continues to persist across much of the West, the Great Basin, and the central-to-southern Great Plains. Unfortunately, a dry winter is predicted for the Southwest states, which won't help the drought situation. We see an increased snow potential over the upper Midwest, with some other areas across the Midwest having normal snowfall amounts forecast this month (0/white areas).
