A significant, long-duration winter storm will bring widespread heavy snow, sleet, and freezing rain from the Southern Rockies to New England through Monday. Widespread travel disruptions, prolonged power outages, and vast tree damage is likely. Frigid temperatures, gusty winds, and dangerous wind chills will expand from the north-central US to the Southern Plains, MS Valley, and Midwest. Read More >

Damaging Winds Across Southeast Wisconsin A strong line of thunderstorms was tracked from western Illinois as they moved northeast. As they approached southern Wisconsin the northern portion of the storms formed into a bowing segment with very strong winds associated with it as it progressed through southern Rock and Walworth Counties. This bowing segment weakened on the north end as it pushed further northeast but the main line remain strong pushing northeast rapidly. Shortly after the first bowing segment weakened another smaller bowing segment formed in western Racine County and tracked northeast through southern Milwaukee County. Both of these bowing segments are responsible for the strongest winds with this event, however, reports of strong to severe winds occurred all along this line of storms as they tracked through southeast Wisconsin. The strongest winds from this event appear to be in the Village of Walworth/Fontane-On-Geneva areas. In addition to severe winds there was a concern for weak, short-lived tornadoes as well. With this event 2 tornado warnings were issued, one in eastern Walworth County and western Racine County and another in eastern Kenosha County. Both were issued after rotation was seen on radar with tornadic features associated with it. No tornadoes have been reported/confirmed. |
