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. 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. I dont want to be guilty of self-promotion, but I recently published a. Below, you can see the progress of some historical multi-year La Nina episodes, with only two events previously having a 3rd-year event. 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. 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). Have a comment on this page? This is typically on the western and southern border of low-pressure systems, where the northerly and northwesterly flow pulls down cold air from the north. Submitted by Nathaniel.Johnson on Wed, 03/01/2023 - 19:55, In reply to Atmospheric rivers by Jiwon Kim. Not sure how much that was a factor. 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. Video. Most areas dry, breezy and very mild, though a few showers perhaps affecting southern England for a time. We dont end up with enough events in each group, and the noise of chaotic weather variability hides the signal we are trying to identify. So what's in store? Despite the headlines, the winter weather predictions from both publications have a lot of similarities this year. 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. As always, we start with the ECMWF, the most often used and highly regarded seasonal forecasting system. Long-range forecasters from a National Weather Service agency have issued their outlook for the 2022-2023 winter season. This is the part of the atmosphere where the air temperature is at 0C. To determine this signal, I first calculated the average of the December-January Southwest U.S. precipitation across all 30 ensemble members for each La Nia. Instead, the pattern looked a bit more like the positive phase of the Pacific Meridional Mode. This question often boils down to whether there were subtle variations in the sea surface temperature pattern that preconditioned the atmosphere for wetter-than-usual conditions in the region (2). It was developed by the United Kingdom Met Office, which is where the initials UKMO come from. Submitted by rebecca.lindsey on Thu, 02/23/2023 - 10:32. This winter it seems the temps were fairly uniform across the equator. That's a good point! Difficult to impossible travel across wide swaths of U.S. due to coast-to-coast storm. I also agree that relying on ENSO indices for a seasonal forecast is a recipe for a busted forecast, particularly IF the forecast is not interpreted correctly. The firm predicts temperatures that are normal to slightly below normal for nearly all of the country from November 2022 to March 2023. The February snow depth forecast shows continued increased snowfall potential over the northwestern United States and expanding over western and southern Canada. 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 . This is can be seen in the NOAAs latest official Winter 2022/2023 temperature forecast for the United States. . 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. 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. 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. We can also see more snowfall hinted in this run over southern Great Britain. Hello climate.gov administrator, You always provide in-depth analysis and understanding.

Preparations underway for winter storm southwest 15 hours ago . But note more snowfall potential remains over the u pper Midwest. Historically, a strong blocking high-pressure system in the North Pacific is the most typical effect of a cold ENSO phase. 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. $13.99 buys a year's worth of wisdom in the palm of your hands, online community access and a 2023 Farmers' Almanac ! Turning to Slide 5. Here are some useful tips.

Three events went neutral in the third year, and three phases shifted into an El Nino in the third season. 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,. And we can expect plenty of it this winter, according to the Farmers' Almanac, which recently released its 2022-23 Extended Weather Forecast. 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. 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. Get The 7 DMV newsletter in your inbox every weekday morning. More snowfall is still forecast in the upper Midwest, with some hints of more snowfall around the central Great Lakes. Fast, informative and written just for locals. This area is still feeling theeffects of the past 3 VERY Dry Winters. 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. The February snow depth forecast shows the snowfall potential reducing further over most of Europe. One exception is southwestern Canada and higher elevations in the western/northwestern United States. Hopefully Nat will have a chance to turn this into a paper, but it will have to wait for a lull in his schedule. That part of the country also is expected to receive less snow than normal. Overall, however, the winter season is not predicted to be overly wet. Thanks for your questions. - 29 US states are under winter weather alerts as people brace for a winter storm expected to bring heavy snow . Sunshine and showers on Sunday. If we were to zoom into the tropical region, where sea surface temperatures have the greatest global climate impact, we would see some sea surface temperature differences of up to 0.2 C in the tropical Pacific and Indian Oceans. The MJO certainly can interfere with ENSO, particularly during development of ENSO through the MJO influence on tropical westerly wind bursts. All I can say is that I don't have any reason to rule it out as a contributor, and I think this idea will be explored more in the years ahead. Story of winter 2022/23. The February snowfall forecast indicates continued potential over the northern parts of Europe. This video and related map images can also be accessed online at www.climate.gov/winter2022-23.

Submitted by Tony Arnhold on Thu, 03/02/2023 - 16:38. Thanks for raising some good points! As we discussed in this post, La Nina typically causes a reduction rather than increase in western U.S. atmospheric river activity. The pattern seems to be under the influence of a high-pressure system, as the forecast does not permit a lot of large-scale snowfall scenarios and snow accumulation. The climate model produces a total of 630 possible climate outcomes covering all La Nias from 1951-2020. You can see a strong snowfall anomaly over the Midwest and the Great Lakes, expanding over the northeastern United States. Check out the full 2022-23 Extended Winter Weather Forecast from The Farmer's Almanac below. I'm pleased you're joining us today to discuss the Southwest Gas Holdings fourth quarter and year-end results. As the monsoon rain band is situated south of the Equator, the Mekong sub-region . We received 6.45 inches of precipitation (that includes snowfall as liquid equivalent), which is a whopping 3.53 inches above normal - more than double the . Europe is not known to have any specific/direct influences, as it is too far from the source regions. An important global weather factor is ENSO. The almanac, which releases an annual long-range.

Rains by Scott Yuknis. (NOAA Climate.gov, based on NWS CPC data). 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. In mid-January, the Farmers Almanac says, temperatures could drop as low as 40 degrees below zero in parts of the region. Overall, the UKMO is much more dynamic than the ECMWF and leaves more possibilities open regarding pattern development. NOAA Climate.gov image, based on precipitation data from NOAAs Precipitation Reconstruction over Land (PREC/L). Thank you, Clara, for the kind words! Thanks for your comment, Craig. (Head to footnote 6 for all the gory math details.). Below is an image that compares the latest forecast to the previous one. Forecasts hint at abnormal UK winter: whats the long-range outlook?

You will see the average snowfall forecast for the meteorological Winter season, covering the December-January-February period. Any time. Severe Weather Europe 2023, Also, we will keep you updated on other developing weather trends, so bookmark our page. 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. 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%). Technically, this value also will reflect, in part, the increases in greenhouse gas increases in the simulation, but this effect on precipitation is relatively small. We have also produced an image that shows the snowfall forecast change compared to the forecast from the previous month. Several inches of wet snow are likely. The coldest periods will be in late November, mid- and late December, and mid-January. Their precip map show wetter that normal conditions for California during these types of events. 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 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. We'll let you know if/when he does! Most of Europe is forecast to have less snow depth by mid-winter. We have seen a stronger-than-normal jet stream throughout the Southwest, which has brought the wetter conditions this winter. I need a storm to track south of me without occluding for once.

Regions further east, on the other hand, will probably experience precipitation levels more typical for the time of year. 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? 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. However, for the UK, being an island surrounded by the milder water, the air can often warm up slightly before it reaches our shores, and we often see rain rather than snow, or, even trickier to forecast; a mix of rain, sleet and snow.. 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. 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. This precipitation will either be rain or snow, depending on just how cold the air is, and where the freezing level is. For this analysis, I am using simulations of monthly climate from the Geophysical Fluid Dynamics Laboratory (GFDL) climate model called SPEAR, the same model that contributes seasonal forecasts to the North American Multi-Model Ensemble (NMME), but here the experiment is designed to analyze the climate effects of the observed sea surface temperature evolution from 1951-2020 (4). NOAA says the outlook does not project seasonal snowfall accumulations as snow forecasts are generally not predictable more than a week in advance. This 2021-2022 U.S. Winter Outlook map for precipitation shows wetter-than-average conditions are . Winter Forecast for Southwest Michigan for 2022/2023 Impactful Winter Weather On the Way A storm system will move into Lower Michigan for Friday, bringing primarily snow but some light freezing rain could mix in across the far south. 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. Above all thank you for the richness of the information but i take note that some (data simulation methods) may tend to under-estimate (under fit) and others may overestimate (over-fit) an ulterior assumption , choosing the best ( mathematical) simulation methods may sometimes tell a good tale even with the presence of short data window . Sign up for the Climate Coach newsletter, in your inbox every Tuesday and Thursday. A Tale Of Two Winters Across The US, According To Old Farmer's Almanac The Old. The January snow depth forecast shows a similar pattern of more snowfall from western Canada into the northwestern United States. Submitted by Nathaniel.Johnson on Thu, 02/23/2023 - 17:43. We know that all La Nias feature below-average surface temperatures in the central and eastern equatorial Pacific, by definition, but the details vary from event to event. The most important ingredients for snowfall are the air being cold enough and a supply of moisture. Last month was. This model has been quite consistent with low snow accumulation since the early September runs. 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. As you can never trust a single forecast model, we always tend to use the UKMO long-range forecasting system along the ECMWF. The circulation of the strong high-pressure system promotes the development of a low-pressure region over Alaska and western Canada. Despite the rocky end of the year, Southwest reported a $539 million profit for 2022. Just checking the maps at this site, we can see some regions, like you mention, that have been drier than normal over the past 60 days. Chris Bilbrey, a forecaster with the Colorado Avalanche Information Center, digs a pit with Rebecca Hodgetts, southern mountains lead . Based on the Farmer's Almanac winter 2022-2023 predictions for the upcoming chilly season, the report shows that . I realize that this winter has been more eventful in other parts of the country, notably in the western U.S., where torrential rains and heavy mountain snows occurred in December and January. (Please understand we are not monitoring the blog 24/7.). Can MJO interfere with ENSO climate? With temperatures so warm winter and the chance of snow feel somewhat distant. This looks close to a usual historical snowfall pattern in a La Nina winter. By January, most of the country is mild, with lower temperatures farther north and a serious chill entering the Upper Midwest and Great Lakes region by February, while the Southeast especially toward Florida, warms up. AccuWeather meteorologists break down which areas will. 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). This is referring to the kind of divide where one half of the U.S. could be blistering cold, while the other will be so mild. But in general, AccuWeather is predicting a season of less snowfall on the Eastern Seaboard. Light winds. Again, there is an expectation that January and February will see more of an influence from the Atlantic, with the ECMWF maps indicating near-average precipitation levels for most of the UK. This latest forecast cycle interestingly shows more snowfall over the western United States and also the Midwest. Follow severe weather as it happens. Tonight should be the chilliest for a while. Among the winter outlooks issued by meteorologists so far, most agree that the southern United States will be drier and warmer than normal, with the best chance of colder and stormier-than-normal conditions in the northern tier, Midwest and Ohio Valley.
