That can be interpreted as a potential route of winter cold air outbreaks down from the Midwest to the south, creating occasional snow events. 7 day. It was the largest snowfall of the season so far for Halifax and other communities of Nova Scotia. In turn, the NAO, PNA and AO combinations--some of which can be reasonably forecast on intraseasonal scales--demonstrate that some of our wettest winters can come in a La Nina year. It's important to keep in mind that not every location in the Southwest has been wetter than normal lately. Submitted by Nathaniel.Johnson on Sun, 02/26/2023 - 20:08, In reply to Thanks Nat for this cogent by Clara Deser. The UK is set to be hotter than Greece over the weekend as the countrycontinues to experience unusually warm temperatures this October. After this, the December Full Moon will fall on December 19 and the Winter Solstice - marking the shortest day of the year - will occur on December 21. In this blog post, I hope to get this conversation rolling! 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. Long-range forecasters from a National Weather Service agency have issued their outlook for the 2022-2023 winter season. Southwest U.S. Newfoundland, Labrador; Nova Scotia, Prince Edward, New Brunswick, Quebec; Ontario; Alberta, Manitoba, Saskatchewan; British Columbia; 2023 Summer Extended Forecast; 2022-2023 Extended Winter Forecast; 2022-2023 Canadian Extended Winter Forecast; 20 Signs Of A Hard Winter Ahead; Weather Lore; Weather History; Our Forecast Accuracy That forecast extends to some popular California ski resorts. To better understand the ENSO changes, we produced a video showing the La Nina anomalies from Summer into Fall. The Farmers Almanac winter snow forecast is predicting an early start to winter, with a cold and stormy December. This was aligned with the Farmer's Almanac predictions, which stated that January 2022 would be hit with frigid temperatures. The storied old journal's extended weather forecast predicts "plenty of snow, rain and mush as well as some record-breaking cold temperatures! In addition to this, there is a reduced chance of stormy weather and gales. More precipitation is typical over the northwestern United States, the Great Lakes, and parts of the northeast. air travelling from north to the south) bring the air straight from the Arctic and over a cold sea to reach the UK. My calculation that follows confirms this suspicion. Perhaps more relevant for this discussion, the teleconnections forced by the MJO also can interfere with those of ENSO. The widely followed youtube weather channel, is calling for a mixed bag of weather this upcoming winter season. For completeness, I will mention that there are other potential sources of seasonal predictability, such as stratospheric, cryosphere, land surface or radiative forcing variations, but sea surface temperature variations generally are the most important. This early winter, the Southwest had 65% more precipitation than normal according to this precipitation dataset, which is the second highest La Nia total since 1951. Submitted by Finn Stiles on Sat, 02/25/2023 - 05:01. Below we have an Official NOAA CPC probability forecast graphic, which shows the long-range forecast of the central ENSO region. 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. Thank you for your question! This is a reflection of the pressure changes in the latest model forecast. Of course, as with all these predictions, they are just indications of the long-range patterns. While December was above-average as far as the temperature goes, January was a different story. 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. 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. This winter it seems the temps were fairly uniform across the equator. In the East, the almanac predicts above-average snowfall for a vast area, from North Carolina to central New England to the Ohio and Tennessee Valleys, as well as the Great Plains. December-February: January-March: This video and related map images can also be accessed online at www.climate.gov/winter2022-23. Therefore, the variations among these 21 ensemble-averaged values, quantified as a standard deviation of 0.194 mm/day, largely reflect the effects of the different sea surface temperature patterns among the 21 La Nias. Transcript (PDF): October 20 virtual media briefing on Winter Outlook 2022, National Centers for Environmental Prediction, National Integrated Drought Information System. Wetter-than-average conditions are most likely in western Alaska, the Pacific Northwest, northern Rockies, Great Lakes and Ohio Valley. That doesnt mean that the different flavors of La Nia cannot be important for Southwest U.S. precipitation, and its worth trying to better understand the simulated La Nia precipitation variations. Thank you for the immense and informative analysis . But now, we will look at actual Winter snowfall predictions from the latest forecast models. Submitted by rebecca.lindsey on Thu, 02/23/2023 - 10:32. As you can never trust a single forecast model, we always tend to use the UKMO long-range forecasting system along the ECMWF. Can you trust The Old Farmers' Almanac's winter weather predictions? Submitted by emily.becker on Thu, 02/23/2023 - 16:54. They have literature on Modoki La Ninas. So what exactly does this mean for the winter weather patterns and snowfall potential? Jasmine Blackwell,jasmine.blackwell@noaa.gov, (202) 841-9184, Drought to persist in Great Plains, parts of West and expand, Audio: October 20 virtual media briefing on Winter Outlook 2022, National Oceanic and Atmospheric Administration, U.S. Winter Outlook: Warmer, drier South with ongoing La Nina. Although such climate models are rather sophisticated and reliable, they are imperfect. I did just one set of analyses focused on one particular region with one climate model, and thats why I stated up front that this is just the start of the conversation. Light winds. 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. First is the ECMWF, and then it is the UKMO. Its conceivable that such differences could influence precipitation in the Southwest U.S., but these differences are much smaller than the amplitude of the largest average La Nia tropical Pacific sea surface temperature anomalies, which approach 2 Therefore, it is difficult to see how such small sea surface temperature differences could have an influence that is comparable with the average La Nia influence. Anywhere. This seasonal U.S. Drought Outlook map for November 2022 through January 2023 predicts persistent widespread drought across much of the West, the Great Basin, and the central-to-southern Great Plains. Three events went neutral in the third year, and three phases shifted into an El Nino in the third season. This precipitation will either be rain or snow, depending on just how cold the air is, and where the freezing level is. Understanding what teleconnection patterns we can and cannot predict on these seasonal time scales remains a big research topic. We first have to take a quick look at the leading global weather driver for the upcoming winter season, La Nina. Last winter, Boston finished the season with. That means that this post is definitely not the last word on this topic! Flannel, hot chocolate and snowshoes are in the winter forecast from the Farmers' Almanac, which is predicting a shivery 2022-2023 winter for most of the United States. That means that most teleconnection patterns that influence U.S. climate are what we consider "internal to the atmosphere" and tend to grow and decay on time scales of a couple of weeks. My conclusion: the chaotic weather variations are about 14 times more important than the variations in La Nia amplitude or flavor for Southwest U.S. precipitation, which is consistent with the figure above. The UK winter weather forecast 2022/2023 Will it snow in the UK this year? Long-range weather forecast for The January snow depth forecast shows a similar pattern of more snowfall from western Canada into the northwestern United States. It added its 10-day or longer forecasts are only . So what's in store? But take note of the trough of equal temperatures probability extending down low into the south-central states. (NOAA Climate.gov, based on NWS CPC data). WeatherBell is forecasting slightly above-normal snowfall, 125 percent of the seasonal average, in the Midwest, through the Ohio Valley and into the interior Northeast. 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). More. Areas depicted in white are regions where climate signals are weak and Share sensitive information only on official, secure websites.. Snow-covered field in Kansas. Submitted by Nathaniel.Johnson on Wed, 03/01/2023 - 19:55, In reply to Atmospheric rivers by Jiwon Kim. 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. The lowest temperatures are expected in the Ohio Valley into the Upper Midwest, which are forecast to be 1 to 3 degrees below normal. Submitted by Mohammad Al-khateeb on Sun, 02/26/2023 - 03:19, Submitted by Aaron on Tue, 02/28/2023 - 10:46, What do you think of the recent University of Washington study postulating that this kind of triple year La Nia event may become more common and could in fact be the temporary result of cooling in the Pacific Ocean due to increased melting of ice and snow in Antarctica?https://www.washington.edu/news/2022/10/03/study-suggests-la-nina-winte, Submitted by Lois on Tue, 02/28/2023 - 11:22. Here is what the Met Office is predicting for the coming weeks. 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. The standard deviation of this set of values is 0.725 mm/day. 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? below-average surface temperatures in the central and eastern equatorial Pacific, signal relative to the noise of random weather variability, Stratospheric warming due to Tonga volcano, https://www.washington.edu/news/2022/10/03/study-suggests-la-nina-winte, Southeast Colorado and Northeast New Mexico. So, the bottom line is that the relationship between La Nina amplitude and Southwest U.S. precipitation does not appear as simple as one (or at least I) would expect based on this analysis, and it's something I would like to understand better. I appreciate your support! Thanks for raising some good points! What is this gigantic hole that has appeared in the fields of Turkey? The video covers both precipitation and temperature predictions, polar vortex, arctic blasts, typical snowfall, and regions that will see wamr and dry conditions for winter 2022 - 2023. The Met Office's three-month outlook, for example, suggests this winter is half as likely as usual to be classified as wet. Today's Forecast for Tucson Arizona - kgun9.com is favored for the Southwest, eastern areas of the Great Basin, as well as parts of the central and southern Rockies. Did La Nia drench the Southwest United States in early winter 2022/23? Want to know how your actions can help make a difference for our planet? The February snow depth forecast shows the snowfall potential reducing further over most of Europe. 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. 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 . Finally, do you have any comment on the unusual persistent La Nina-like SOI and multivariate ENSO index (MEI) for the 2020-23 La Nina despite occasional neutral Nino34 SSTA lapses? 2022-2023 California and Southwest Weather Thread We can also see more snowfall hinted in this run over southern Great Britain. Ultra long range detailed weather forecast for South England. More snowfall can be seen in parts of the Midwest and the northeastern United States. If there is one basic theme I've learned from all the postings on this blog is that our climate is very complex with many different parts and ENSO is just one big part of it so there is always going to make any winter outcome far from certain. December is favored to be the chilliest month on the Eastern Seaboard, with lower-than-normal temperatures expected from the Great Lakes down into parts of the Mid-Atlantic and Northeast. Here, I am focusing on the Southwest region south of 40 N that covers most of California, Nevada, Utah, and Arizona, in early winter (December-January). Despite the headlines, the winter weather predictions from both publications have a lot of similarities this year. Comments are placed in moderation and must be approved by a blogger before they are posted. (Head to footnote 6 for all the gory math details.). December finally brings the cold. We will do a monthly breakdown, as there are a lot of details in the monthly forecast that the whole seasonal average does not show. January snowfall forecast shows a similar pattern, with more snowfall over much of southern Canada and the northern half of the United States. We are currently in a La Nina phase, entering its third and final year, likely being replaced by a warm phase for 2023/2024. Regarding whether the increased "waviness" is linked to Arctic amplification, we do not have a scientific consensus on such a link. . These are blog posts, not official agency communications; if you quote from these posts or from the comments section, you should attribute the quoted material to the blogger or commenter, not to NOAA, CPC, or Climate.gov. This will be followed by the Quadrantid Meteor Shower . As we emphasize on the blog, ENSO may tilt the odds toward one outcome or the other, but the forecast is always probabilistic. Below, you can see the progress of some historical multi-year La Nina episodes, with only two events previously having a 3rd-year event. Winter Weather Forecast for 2022 - 2023 | From Direct Weather The circulation of the strong high-pressure system promotes the development of a low-pressure region over Alaska and western Canada. This model has been quite consistent with low snow accumulation since the early September runs. Europe is not known to have any specific/direct influences, as it is too far from the source regions. AccuWeather 2022-2023 Canada winter forecast | AccuWeather However, this pattern may break down during the last third of the month, possibly heralding a return to milder, more unsettled weather. La Nina usually forms during strong trade winds, which can tell us much about the state of global circulation. A somewhat subjective rating of the day's weather, on a scale of 0 to 10. It's difficult for me to see a clear connection between this triple-dip La Nina and the frequent western U.S. atmospheric rivers. 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. Submitted by Nathaniel.Johnson on Thu, 02/23/2023 - 17:47. Can MJO interfere with ENSO climate? AccuWeather's 2022-2023 US winter forecast - Yahoo News 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. While it is still several weeks until the official start of winter on Dec. 21, several organizations are already unveiling their nationwide Winter 2022-2023 forecasts. Ideas and explanations found in these posts should be attributed to the ENSO blog team, and not to NOAA (the agency) itself. AccuWeather 2022-2023 US winter forecast | AccuWeather Winter 2022/2023 Snowfall Predictions: Final Snow Forecast for the That total is deceptive as many areas in Tucson area had 6-7 inches today, Meanwhile Washington DC and Philadelphia have had less than 1/2 inch snow this winter, Submitted by Craig T on Thu, 03/02/2023 - 16:22.

Below we have the latest surface analysis of the tropical Pacific Ocean. Meanwhile, the southern U.S. is expected to have a. Between 9 and 23 November there could be an increasing chance of settled weather from mid-month, bringing a potential for colder, drier weather especially for the north and west, it said. Who we are, what we do and organisational news. NOAA Climate.gov image, based on precipitation data from the NOAA GFDL SPEAR climate model. The precipitation anomalies are divided into 10 evenly spaced bins, and the number of La Nia events is totaled for each bin. The logical conclusion is that, according to the climate model, unusually heavy Southwest U.S. precipitation during December-January of La Nia has very little to do with the sea surface temperatures and instead is more closely tied to short-term and seasonally unpredictable weather conditions, as captured by the variations among the 30 simulations for a given La Nia. Reports from . The February snowfall forecast indicates continued potential over the northern parts of Europe. Thanks for doing those simulations, and for sharing the results here. This winter's total is a record for Bellemont but in 1948-49 there was 153.9 inches at the airport ..still have time to top that record since average March snowfall is about 15 inches, Submitted by Craig T on Fri, 03/03/2023 - 14:34.

Here's Michigan's winter 2022-2023 outlook Annual and monthly snow totals at MSP Airport since 2011-12. A lock ( One of the main features of the UK's weather this year has been the seemingly indomitable prevalence of mild conditions, which has catapulted 2022 into strong contention for the warmest year on record. The jet stream is a large and powerful stream of air (wind) at around 8-11km (5-7mi) altitude. Largely cloudy for all during the afternoon but remaining dry. The figure below shows that most (13 of 21) of the La Nias from 1951-2020 had below-average December-January precipitation in this region (1), although wet early winters during La Nia . The increase this year has been associated with an extension of the jet stream into the Southwest, which we typically do not see during La Nina, and I do not see how the "triple-dip" classification would change that. 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. 30 forecast for Winnetka! NOAA Official precipitation outlook points: Also, we will keep you updated on other developing weather trends, so bookmark our page. A first look at Winter 2022/2023 forecast shows an obvious influence of the third-year La Nina phase. From February to April, below-normal precipitation is forecast in the Southwest and coastal portions of the Southeast, but areas including Texas may see a respite from less-than-normal snowfall and rainfall.
