The latest breakthroughs, research and news from the Met Office. All good scientific studies note their limitations, and this analysis carries some caveats that are familiar to most climate scientists. The pattern in the map is very weak, with very small departures between the two groups. How harsh will winter be? Six organizations issue forecasts. The remainder of the U.S. falls into the category of equal chances for below-, near-, or above-average seasonal total precipitation. 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. What does the latest ocean analysis data show, and what influence did it play on temperature and snowfall patterns in the past? Again, you can see more snowfall than normal, covering a large area from western Canada down into the northwestern United States and the far upper Midwest. Just wanted to Note that not all of the Southwest is receiving Robust Moisture. 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.

Thanks Nat for this cogent and readable discussion! U.S. Winter Outlook: Drier, warmer South, wetter North with return of This is an active area of research and model development, and I know that there are many in my lab who are working on improving the representation of stratospheric processes in our models. Plenty of sunshine is expected across the south over the next few days, matching temperatures in St Tropez in southern France. Winter Forecast 2021 - 2022 #3 - YouTube Several inches of wet snow are likely. 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. Wetter-than-average conditions are most likely in western Alaska, the Pacific Northwest, northern Rockies, Great Lakes and Ohio Valley. Forecasts hint at abnormal UK winter: whats the long-range outlook? Warmer-than-average temperatures are also favored in the Southeastern U.S. and along the Atlantic coast. Thank you for your comment, and I agree that the influence of the stratosphere on seasonal predictability and predictions is an important topic that deserves continued focus.

C) and did not see any substantial differences than when I considered all La Nina episodes. 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. Submitted by rebecca.lindsey on Thu, 02/23/2023 - 10:32. 10 day. Light winds.
