(Please understand we are not monitoring the blog 24/7.). Above-normal precipitation is forecast in part of the Ohio Valley, an area that could pick up above-normal snowfall if temperatures remain low enough. Those rainstorms may cause flooding in the Ohio Valley and along the Mississippi River, AccuWeather says. We either require the cold air to meet a rain-bearing weather front and turn it into snow, or for the cold air to pick up enough moisture from its short journey across the North Sea, to form showers.. By that standing (since 1893), the meteorological winter of 2022-23 was the wettest in Minnesota. The circulation of the strong high-pressure system promotes the development of a low-pressure region over Alaska and western Canada. 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. Although it's several months away yet, a typical La Nia winter in the U.S. brings cold and snow to the Northwest and unusually dry conditions to most of the southern tier of the U.S., according.

Since the latest forecast data was released in mid-late November, we now also have the March data included, so we can look at some early Spring snowfall potential. Drought conditions are now present across approximately 59% of the country, but parts of the Western U.S and southern Great Plains will continue to be the hardest hit this winter, said Jon Gottschalck, chief, Operational Prediction Branch, NOAAs Climate Prediction Center. Light winds. The signal of interest is Southwest U.S. precipitation variations due to the sea surface temperature variations during all La Nias. Winter Outlook 2022-23 Has Colder Risks For North, East Note that even the most scientifically advanced seasonal outlooks cannot pinpoint what the weather will be in a particular place at a particular time this far in advance. We will look at two highly regarded seasonal weather forecasting systems. The Met Office adds: What about the moisture? 2021 Associated Newspapers Limited. Images by NOAA Physical Science Laboratory. 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. . 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.

Here's Michigan's winter 2022-2023 outlook 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 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. Winter- It's Coming! Records back to 1893 are considered the most reliable and qualify for the "modern" record. Submitted by Nathaniel.Johnson on Thu, 02/23/2023 - 17:47.
