A FLOOD WATCH is in effect until 1 AM Thursday morning for west-central Wisconsin, including the counties of GRANT, CRAWFORD, RICHLAND, VERNON, MONROE, JUNEAU, ADAMS, and VERNON (this includes the La Crosse metropolitan area). In Iowa, this includes the counties of ALLAMAKEE AND CLAYTON.
The Storm Prediction Center says there is a SLIGHT RISK of severe thunderstorms today and tonight for the southeastern quarter of Minnesota, the northwestern third of Iowa, and west-central through northeastern Wisconsin (south of a Minneapolis to Eagle River line and north of a Prairie du Chien to Green Bay line), and a MARGINAL RISK of severe thunderstorms of the rest of the southeastern third of Minnesota, the rest of the northwestern two-thirds of Iowa, and the rest of Wisconsin (except for the extreme southeastern part of the state south of a Beloit to Sheboygan line). A warm and humid air mass will cover the central Midwest today. A low pressure system will move from northeastern Colorado to northwestern Wisconsin along a stationary front. Thunderstorms may be occurring in the morning in northern Wisconsin, perhaps intensifying in the afternoon with a threat for high winds, hail, and heavy rainfall. Additional thunderstorms will develop in Minnesota and Iowa in the afternoon and move eastward into Wisconsin at night. High winds, hail, and heavy rainfall will be the main threats, although isolated tornadoes may be possible where thunderstorms development initially takes place, mainly in Minnesota and Iowa.
The Storm Prediction Center says that there is a MARGINAL RISK of severe thunderstorms over extreme southeastern Minnesota, most of Iowa, northwestern Illinois, and the southern half of Wisconsin (south of a LaCrosse to Stevens Point to Green Bay line). As a low pressure system moves through Lake Superior, a cold front will move toward western Wisconsin as another low pressure system moves along the front into Minnesota. Thunderstorms are likely on Wednesday through the central Midwest, but widespread cloud cover may lead to cooler temperatures and a lesser threat of severe thunderstorms. Isolated severe thunderstorms are possible with high winds, hail, and heavy rainfall as the main threats.
