Late Season Chill Overspreads Much of U.S.

billings snow

The calendar might say it’s mid-May, but Mother Nature is saying something else for much of the country this weekend.

Well below average temperatures for this time of year have overspread much of the central and eastern portions of the U.S., with frost and freeze concerns from the Dakotas into New England and cooler than average temperatures extending from Denver, Colorado to the Carolinas.

Chicago, Illinois only reached 47° on Saturday (average high: 69°), while Duluth, Minnesota only reached 36°, a full 26° below the city’s average high for May 14th of 62°.

Snow accumulated lightly in parts of Michigan and Wisconsin on Saturday, although amounts didn’t top a few wet inches. Some snow is possible in New England and the Rocky Mountains’ highest elevations this week.

On the positive side, the unseasonably chilly weather has temporarily halted what is typically the busiest severe weather month of the year. After a busy week of strong storms, the end of the week and this weekend has been somewhat calmer. Widespread cooler air makes it more difficult for severe storms to develop, as they usually thrive off warm, humid air.

Warmer weather gradually returns by mid week, although the severe weather threat will return far before that. Monday and Tuesday could be active severe-wise in Texas and portions of the deep South. Stay with WeatherNation for the latest on all of it.
