The figure above shows the sea surface temperature differences between the high- and low-precipitation groups in the SPEAR simulations. Alongside the festive buzz and Mariah Carey's unstoppable annual return to relevance, December has decided to throw us a notably unusual weather pattern. Six organizations issue forecasts. The circulation of the strong high-pressure system promotes the development of a low-pressure region over Alaska and western Canada. 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. Below normal temperatures are favored from the Pacific Northwest eastward to the western Great Lakes and the Alaska Panhandle. 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. We will take a closer look at the weather influence that La Nina usually shows over North America, which is under a more direct influence. Submitted by Nathaniel.Johnson on Thu, 03/02/2023 - 17:00, In reply to Southeast Colorado and Northeast New Mexico by Tony Arnhold, Science & information for a climate-smart nation, torrential rains and heavy mountain snows, NOAAs Precipitation Reconstruction over Land (PREC/L). The most important ingredients for snowfall are the air being cold enough and a supply of moisture. Did La Nia drench the Southwest United States in early winter 2022/23? 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 clearly are not that unusual. 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.

On the other side of the country, temperatures in the Southwest and the Rockies are expected to be well above average. Since the ocean is the same in all the simulations, the models will produce a range of outcomes that account for the role of atmospheric chaos for each individual La Nia. On average across the UK, there are only 15.6 days a year when snow is on the ground, though this rises to 26.2 days for Scotland alone. WARNING: Long-range forecasts are rarely accurate. Let us know. To better understand the ENSO changes, we produced a video showing the La Nina anomalies from Summer into Fall. So, I did not see any obviously linear effect of La Nina amplitude in the observational analysis. During the years of 2022, 2023, and 2024, an event like no other struck the ENTIRE United States, unleashing total chaos upon the country. The Ohio winter 2022-2023 predictions are predicated on this being the second year for the current La Nina weather pattern. The snowfall forecast focuses the most snowfall on the Midwest. 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. which became the state's newest city in January 2022, . Good analysis! 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. 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 . Below, you can see the progress of some historical multi-year La Nina episodes, with only two events previously having a 3rd-year event. 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. But looking at the March snow forecast image below, we can see most of Europe having a lower-than-normal end to the snow season. Warmer-than-average temperatures are also favored in the Southeastern U.S. and along the Atlantic coast. Maximum temperature 7C. Categories Long range / seasonal forecast.

We see more snowfall over the northwestern and northern United States and southern Canada. According to the most recent update of our European Centre for Medium Range Weather Forecasts (ECMWF) model maps, almost the entire country can expect average temperatures across the month to fall below the norm, perhaps even by 2C or more in some areas. 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. So, that gets to the main point of the post. This will impact the Friday evening commute with delayed travel likely. This is the part of the atmosphere where the air temperature is at 0C. 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. This is a reflection of the pressure changes in the latest model forecast. As you can never trust a single forecast model, we always tend to use the UKMO long-range forecasting system along the ECMWF. This area is still feeling theeffects of the past 3 VERY Dry Winters. Submitted by emily.becker on Thu, 02/23/2023 - 16:54. Video. Overall, the UKMO is much more dynamic than the ECMWF and leaves more possibilities open regarding pattern development.
