southwest winter forecast 2022

We will look at two highly regarded seasonal weather forecasting systems. There are also some hints of a cold event reaching down to the south-central United States. This is a region of the equatorial Pacific Ocean that changes between warm and cold phases. That's why Nat used model simulations to look at the relationships here, finding that there's no preferred pattern to the sea surface temperature for wet SW winters. The winter outlook from WeatherBell Analytics, a weather consulting firm, should put more pep in the step of snow lovers. A lock ( In winter, the land gets cold more quickly than the sea, so where there is a lot of land and very little sea, such as the huge interior of continental Europe, Canada or the United States, it gets cold enough for snow to fall frequently, it says. 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. Check out our new Learn Weather page linked below, containing information on all things related to weather in all the seasons! 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. The official NOAA Temperature outlook points: The official precipitation forecast is also quite similar to the latest model forecasts. For the first three months when winterlike conditions begin in earnest November, December and January abnormal cold is not expected anywhere in the country. 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. Updated 15 February 2023. This way, the ENSO significantly impacts tropical rainfall and pressure patterns, strongly changing the atmosphere-ocean feedback system. The rest of the United States shows less snowfall than normal, but that does not mean no snow at all. WARNING: Long-range forecasts are rarely accurate. UKMO uses a different parameter than the ECMWF but correlates directly with snowfall also. Further showers on Monday and more likely wintry, with some snow possible over hills on Tuesday. In the West, generally dry conditions will do little to ease the regions persistent drought. 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 . Above-normal precipitation is possible in northwestern Montana, northern Idaho and northeastern Washington state. The storied old journal's extended weather forecast predicts "plenty of snow, rain and mush as well as some record-breaking cold temperatures! 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. However, the Met Office has issued a yellow warning for parts of Scotland, including Highlands, Eilean Siar and Strathclyde, and Northern Ireland on Friday, meaning residents should expect heavy rain and some flooding of a few homes and businesses. Difficult to impossible travel across wide swaths of U.S. due to coast-to-coast storm. The February snow depth forecast shows the snowfall potential reducing further over most of Europe. Temperatures will likely fluctuate between cold and mild, north to south, but will probably average out around normal. Mostly dry but the risk of showers towards the evening which could turn wintry across high ground. Looking at the overall average forecast and comparing it to the previous forecast, we can see that the latest run has less snowfall over most of Europe, except towards the east and south. Cold weather to arrive this weekend, bringing wintry showers to Scotland, Nanoplastics now ubiquitous in air, water and soil, says new report. So, that gets to the main point of the post. Europe features mostly warmer than normal conditions over northern parts, with a storm track over the southwest . Hopefully Nat will have a chance to turn this into a paper, but it will have to wait for a lull in his schedule. Sea Surface Temperature AnomalyDecember 2010. 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. Comments are placed in moderation and must be approved by a blogger before they are posted. Warmer-than-average temperatures are favored in the Southwestern United States, across the Southeastern states, and along the Atlantic coast. Whether you are a fan of snow, here is the latest roundup of what meteorologists are saying about the weather in the coming months. Difference in DecemberJanuary sea surface temperature anomalies ( C) between the wettest 20% and driest 20% of Southwestern U.S. La Nia outcomes simulated by the GFDL SPEAR climate model. What is this gigantic hole that has appeared in the fields of Turkey? Thanks for raising some good points! AccuWeather's range for the Twin Cities is 75-124% of normal, which means it could be below average or above average. If youre wondering what sort of calculations led to this conclusion, then I will give you all the details here. In line with December's blocking high pressure, the lack of weather fronts moving in from the Atlantic mean the month is expected to be much drier than average for western areas, especially in Scotland. So what exactly does this mean for the winter weather patterns and snowfall potential? The February snowfall forecast indicates continued potential over the northern parts of Europe. It calls for snowfall to be above normal toward the East Coast as well. 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. Heres what that means. The first day of winter and the shortest day of the year, officially arrives on December 21, 2022, but that doesn't always mean that the cold temperatures and snow storms will wait until then. The most common wind direction in the UK is south-westerly though, so more often than not we get relatively mild air from the Atlantic bringing rain, rather than this cold air from the north and east which often turns any rain to snow..

This is can be seen in the NOAAs latest official Winter 2022/2023 temperature forecast for the United States. We always focus on trends and probabilities, but still, variation is key. 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. All good scientific studies note their limitations, and this analysis carries some caveats that are familiar to most climate scientists. Submitted by Nathaniel.Johnson on Fri, 02/24/2023 - 16:47, In reply to DEC/JAN 2022-23 Southwest U.S. London and other areas in the south of England will surpass 20C higher than Athens, which is predicted to peak at 20C over the weekend. From February to April, above-normal temperatures are projected to continue along the East Coast, in the Southeast and into the Southwest, with the greatest chance of warmer weather along the. (Image credit: Getty images), Video highlights from NOAA's 2022-2023 Winter Outlook that provide seasonal predictions for temperature, precipitation and drought. Out West, even if temperatures are mild, the predicted above-average precipitation can help to ease the regions drought. That's a good point! This U.S. Winter Outlook 2021-2022 map for temperature shows warmer-than-average conditions across the South and most of the eastern U.S., while below average temperatures are favored for southeast Alaska and the Pacific Northwest eastward to the Northern Plains. But that does not mean it has no impact. Reports from . Submitted by emily.becker on Thu, 02/23/2023 - 17:12, In reply to sampling differences by John N-G. That's a good question! They have literature on Modoki La Ninas. This area is still feeling theeffects of the past 3 VERY Dry Winters. By weather.com meteorologists October 13, 2022 At a Glance A generally colder than usual winter is expected in the northern tier of states. Durango Herald 3:40 AM MST on Mar 4, 2023. The latest breakthroughs, research and news from the Met Office. 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. Even with the mild winter in the East, we had two notable cold spells, one in late December and the other in early February, so there have been some wild swings this winter! 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. Submitted by Bob G on Thu, 02/23/2023 - 12:57. Although such climate models are rather sophisticated and reliable, they are imperfect. 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. How important is the difference in La Nia intensity between the two samples. Warmer and drier winter weather prevails over the southern states. An important global weather factor is ENSO. The signal-to-noise ratio is typically calculated as a ratio of variances, which are the squares of the standard deviations. Last month was. Submitted by emily.becker on Thu, 02/23/2023 - 17:04, Submitted by Bob G on Thu, 02/23/2023 - 18:30, In reply to It's hard to say without by emily.becker. Also, we have the March snowfall forecast data. Another meteorological winter is drawing to a close, though it feels like some of us in the East are still waiting for winter to arrive (not a single inch of snow here in central New Jersey so far!). Submitted by Nathaniel.Johnson on Thu, 02/23/2023 - 17:47. The Old Farmers Almanac is predicting a divided nation with harsh winter in the East and mild weather in the West. The largest departures were in Wisconsin. Submitted by Matt on Thu, 02/23/2023 - 11:44. ET. The Majority of these Atmospheric Rivers have missed this area and only the last month has some of the area received measurable Moisture. NOAA Climate.gov image, based on precipitation data from the NOAA GFDL SPEAR climate model. Staying largely cloudy into the evening but some clear spells could develop overnight where temperatures will drop and some frost could develop. Submitted by Nathaniel.Johnson on Sun, 02/26/2023 - 20:08, In reply to Thanks Nat for this cogent by Clara Deser. 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. What its also doing though, is helping develop the kind of south-westerly airflow which is spinning in some of these periods of wet and windy weather, but also the warmer kind of continental air over the UK much more than average for the time of year.. 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. More snowfall can be seen in parts of the Midwest and the northeastern United States. We are going to show you their forecast for the upcoming winter, but first, a warning. Typically, the first influence of these ocean anomalies can be seen in the jet stream patterns changing. NOAA Climate.gov image, based on precipitation data from NOAAs Precipitation Reconstruction over Land (PREC/L). Due to arctic amplification (or not) the jet steam has been "wavy" this winter bringing colder than average temperatures to the SW (I live in Tucson) and unusual warmth to the east. Are you Weather-Ready for spring hazards? More U. S. drought in a second-year La Nia? To better understand the ENSO changes, we produced a video showing the La Nina anomalies from Summer into Fall. On the other side of the country, temperatures in the Southwest and the Rockies are expected to be well above average. These sorts of patterns occur in the simulations I described, but they are part of the "weather noise" that gets averaged out among the 30 simulations. The December snow depth forecast shows less snow cover over most of the United States and Canada. 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. 16 min read. Largely cloudy for all during the afternoon but remaining dry. Although the official winter forecast from the National Oceanic and Atmospheric Administration will not come out for another few weeks, the agencys Climate Prediction Center does issue official outlooks for temperature and precipitation up to 13 months in advance. the Desert Southwest if another snow-lacking . 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. When we divide up the observed record even further, e.g. Below normal temperatures are favored from the Pacific Northwest eastward to the western Great Lakes and the Alaska Panhandle. Can MJO interfere with ENSO climate? This latest forecast cycle interestingly shows more snowfall over the western United States and also the Midwest. Here is what the Met Office is predicting for the coming weeks. To solidify this conclusion, I continued my investigation by calculating how much the variations in the La Nia sea surface temperature pattern contribute to the variations in Southwest U.S. DecemberJanuary precipitation in the SPEAR simulations. From my experience, the superposition of the ENSO and MJO teleconnections can be treated as linearly additive, so the MJO influence (like what's shown here) can constructively or destructively interfere with the expected ENSO influence. The ENSO influence is spread globally through this feedback system, creating different Winter temperature and snowfall patterns. For full-year 2023, it plans to expand flying as much as . 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). Overall, however, the winter season is not predicted to be overly wet. 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. Weather.coms official winter outlook like NOAAs and AccuWeathers calls for above-normal temperatures in the South, while far-northern parts of the continental United States manage to stay below average, these conditions being driven by La Nia. I am wondering if there is a possibility that the triple-dip La Nina event from 2020 could create some kinds of conditions that make atmospheric rivers more active, resulting in the occurrence of torrential rains over the western United States. Submitted by Bob G on Thu, 02/23/2023 - 18:35, In reply to sampling differences by Nathaniel.Johnson. The blue bars indicate the chance of La Nia for each three-month period into winter 2022-23, according to this forecast from early May 2022. . Chris Bilbrey, a forecaster with the Colorado Avalanche Information Center, digs a pit with Rebecca Hodgetts, southern mountains lead . The December snowfall forecast shows some areas with more snowfall over northern, western, and central parts. The data used to produce these graphics is the latest available at the present time, from mid-November. Im basically doing a signal versus noise calculation. 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. Secure .gov websites use HTTPS The cold phase is called La Nina, and the warm phase is called El Nino. This was an interesting post that gave more insights into how La Nia can influence winter precipitation in the Southwest, and how it's more complex than stating that its presence means it'll be dry. Empowering people with actionable forecasts, seasonal predictions and winter weather safety tips is key to NOAAs effort to build a more Weather- and Climate-Ready Nation. (Head to footnote 6 for all the gory math details.). NOAAs Precipitation Reconstruction over Land (PREC/L). Cold ocean anomalies extend across most of the tropical Pacific. We can run multiple simulations in which the ocean is always the sameforced to match observed sea surface temperatures, including all La Nias from 1951-2020but the starting atmospheric conditions are very slightly different each time. If skies are clear, temperatures can fall gradually day-by-day because the sun is weak and there is little cloud to keep in any heat at night. According to NWS Tucson there have been 25 LaNina winters here since 1950. This video and related map images can also be accessed online at www.climate.gov/winter2022-23. Starting with the seasonal average, we see below-average snowfall over most of Europe, which is indicative of a high-pressure dominant pattern. The brown bars indicate events with below-average precipitation, and the green bars indicate events with above-average precipitation. I don't have an explanation except to speculate that the multidecadal enhancement of the zonal sea surface temperature gradient (like what was described in this post) is helping to keep the tropical atmosphere more La Nina-like even when the typical ENSO sea surface temperature indexes are deviating from typical La Nina values. Sunshine and showers on Sunday. 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.
