Winter 2021 could bring above normal precipitation in IL

ILLINOIS – For the second year in a row, La Niña weather conditions will bring above-average temperatures this winter to much of the United States, according to a new forecast released by the National Oceanic and Atmospheric Administration. Meanwhile, residents of other states would be better off bundling up as a cooler, wetter season is on the way.

Illinois is among those expected to experience above-normal temperatures and above-normal precipitation, according to the 2021 winter forecast released Thursday by NOAA’s Climate Prediction Center, a division of the National Weather Service.

The new NOAA forecasts join those released in previous weeks, including The Farmers’ Almanac, The Old Farmer’s Almanac and AccuWeather.

According to the NOAA winter weather forecast, Illinois, along with others in the Great Lakes, could experience wetter than average conditions and an equal chance of below average, near average, above average temperatures. the average.

The NOAA forecast covers three months, December-February.

Wetter than average conditions are forecast for parts of the northern United States, primarily the Pacific Northwest, northern Rockies, Great Lakes, the Ohio Valley, and western parts of the United States. Alaska.

Experts are also closely monitoring states battling the ongoing drought.

Widespread severe to exceptional drought will continue to dominate the western half of the continental United States, the northern plains and the Missouri River basin. However, the Pacific Northwest, northern California, the upper Midwest, and Hawaii are most likely to experience improved drought.

In terms of temperature, warmer than average conditions will most likely be reported in the southernmost part of the United States as well as much of the eastern United States.

Southeastern states, such as Florida, are most likely to experience an increase in temperatures, while below-average temperatures are forecast for Southeast Alaska and the Pacific Northwest towards the east to the northern plains.

The upper Mississippi Valley and small parts of the Great Lakes have equal chances of having temperatures below, near, or above average, according to NOAA.

The NOAA seasonal outlook provides insight into the likelihood that temperatures and total precipitation amounts will be above, near, or below average, as well as how drought conditions are expected to change in the coming months. The outlook does not predict seasonal snowfall accumulations as snow forecasts are generally not predictable more than a week in advance.

NOAA is expected to update the winter outlook on November 19.
