The threat for severe weather makes a return for the start of the workweek. As cold fronts more frequently start to dip down across the continental U.S. this time of year, the threat for severe weather returns. Not only is severe weather a threat, but much cooler temperatures will follow.

Monday appears to be relatively quiet, although there is a marginal risk for some severe thunderstorms to persist across parts of eastern Kansas and Missouri. These storms will mainly consist of what is left from Sunday night’s storms. The forecast doesn’t have any new storm development to occur in the afternoon and evening hours of Monday.
However, an increased threat for severe weather including damaging winds, large hail, and even the threat of an isolated tornado or two is possible Tuesday, stretching from the Dakotas down into Nebraska.
Behind the cold front, significantly cooler conditions will persist Wednesday, spanning from the Pacific Northwest to Minnesota. As the week progresses, the cold front will continue to march to the east.
