AccuWeather's range for the Twin Cities is 75-124% of normal, which means it could be below average or above average. The more forecast data you can look at, the better idea you can get about the expected weather patterns. In the West, the drought persists. 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. A La Nia pattern has persisted into the summer of 2022, and long-range models have been projecting a higher than average chance of a La Nia continuing into the winter of 2022-2023, before possibly weakening in the spring of 2023. Rare 'Triple-Dip' La Nia Increasingly Possible - The Weather Channel which became the state's newest city in January 2022, . Overall we still see less snowfall than normal for the first Winter month. 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. Below we have the latest surface analysis of the tropical Pacific Ocean.

Whether you are a fan of snow, here is the latest roundup of what meteorologists are saying about the weather in the coming months. AccuWeather says that the lingering water vapor in the atmosphere from the eruption could cause a warmer winter than normal but that the magnitude of the effect is unknown. Also, we still seem to be transitioning out of La Nina, which may also have some impact. The December snow depth forecast shows less snow cover over most of the United States and Canada. The January snowfall forecast shows more potential in northern and western Europe. 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. I dont want to be guilty of self-promotion, but I recently published a. The bottom line is that La Nia may tilt the odds toward dry early winter conditions in the Southwest, but La Nia clearly does not eliminate the chance of wet conditions either. How harsh will winter be? Six organizations issue forecasts. travelling for the east to the west) are cold because they arrive from the cold continental interior of mainland Europe. The almanac forecasts cold and wet conditions down even into Florida, with the worst of the cold forecast for January. So what exactly does this mean for the winter weather patterns and snowfall potential? The notably small sea surface temperature differences between the wet and dry groups indicate that the sea surface temperature pattern plays a very minor role in the Southwest precipitation differences during La Nia, according to the climate model. 16 min read. 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. Annual snowfall in the Twin Cities based on the modern 30-year average (1981-2010) is 54 inches, so AccuWeather's range falls between 40 and 67 inches. 2022-2023 California and Southwest Weather Thread Long-Range Weather Forecast for Desert Southwest - Almanac The Euro precipitation forecast outlines the major areas of concern with our snowfall outlook. Submitted by Nathaniel.Johnson on Sun, 02/26/2023 - 20:08, In reply to Thanks Nat for this cogent by Clara Deser. The format of this forecast is simple. 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. Stay safe during severe cold weather.

Submitted by Clara Deser on Sat, 02/25/2023 - 11:39. The rest of the United States shows less snowfall than normal, but that does not mean no snow at all. . Submitted by Nathaniel.Johnson on Wed, 03/01/2023 - 12:10, In reply to Arctic amplification (?) To analyze the effect of different sea surface temperature patterns on early-winter precipitation in the Southwest during La Nia, I first defined two groups: the wettest 20% and driest 20% of simulations. 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. 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. 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. It will modify the jet stream pattern over North America and the Pacific Ocean, extending its reach to the rest of the world. NOAA Climate.gov image, based on precipitation data from the NOAA GFDL SPEAR climate model. ), and I have seen that there are a few studies that point to processes around Antarctica that could be contributing. D.C.-area forecast: Nice today, a few showers early Thursday; Friday Anywhere. Out West, even if temperatures are mild, the predicted above-average precipitation can help to ease the regions drought. One exception is southwestern Canada and higher elevations in the western/northwestern United States. Thanks for raising some good points! Europe features mostly warmer than normal conditions over northern parts, with a storm track over the southwest . Rain, heavy at times, will sweep quickly north-eastwards across most parts. 16 day. Chris Bilbrey, a forecaster with the Colorado Avalanche Information Center, digs a pit with Rebecca Hodgetts, southern mountains lead . 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 . This is not too far from the ECMWF prediction, but we generally see more snowfall in the northern United States. With the La Nia climate pattern still in place, drought conditions may also expand to the Gulf Coast.. 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. . 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). 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. Even modest variations could tip the scale toward wetter or drier conditions in a particular winter. Forecasts hint at abnormal UK winter: whats the long-range outlook? 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). The February snow depth forecast shows continued increased snowfall potential over the northwestern United States and expanding over western and southern Canada. 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. We'll let you know if/when he does! Patchy cloud with some clearer skies. It calls for snowfall to be above normal toward the East Coast as well. The Farmers' Almanac has released its extended winter forecast for 2022 and 2023 in the United States. We did have a high-amplitude MJO phase 3, which often leads to wet conditions on the West Coast. Such heavy precipitation was unexpected prior to the season in a region afflicted with a multi-year severe drought, especially given that we are in the third consecutive winter of La Nia. 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 .

Plenty of sunshine is expected across the south over the next few days, matching temperatures in St Tropez in southern France. The snowfall forecast focuses the most snowfall on the Midwest. 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? Pacific Southwest Another mild winter is expected this year, Goble said. 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. 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. Seasonal outlooks help communities prepare for what is likely to come in the months ahead and minimize weather's impacts on lives and livelihoods. However, there is another way which requires very little wind at all high pressure that becomes established across the UK for a long time in winter.
