...A LINE OF STRONG THUNDERSTORMS WILL AFFECT WESTERN WINONA... SOUTHEASTERN OLMSTED AND NORTHERN FILLMORE COUNTIES... At 325 PM CDT, radar indicated strong thunderstorms were located along a line extending from near Altura to 7 miles east of Stewartville. Movement was southeast at 35 mph.

This includes Interstate 90 in Minnesota between mile markers 220 and 253. If outdoors, consider seeking shelter inside a building.
A lot of sunshine is expected during the day, which will heat our temperatures into the lower 90s but will also increase the instability. With a very unstable air mass in place during the afternoon, another round of scattered thunderstorms is expected to develop. There is a lot of uncertainty regarding where the storms will develop, so there is a broad area of severe potential on Thursday. All of southern Minnesota and northern Iowa are in a Enhanced Risk (Level 3 of 5) for severe weather. The main concerns would be large hail, damaging wind gusts, an isolated tornado, and heavy rainfall.
