Severe thunderstorms as of 6 pm, threatening Lake City, Winona and La Crosse, WI. The main threat appears to be east of Rochester. The cell due east of RST was producing 1.6" diameter hail. This grapic shows the red "polygons" issued by the NWS, the "high-threat areas" where severe weather is imminent. These storms will probably continue to strengthen this evening as they move into Wisconsin, capable of tennis ball size hail, even a few isolated tornadoes.
