The Storm Prediction Center has issued a Severe Thunderstorm Watch until 9 p.m. CDT for a large part of the eastern Dakotas and northwest Minnesota. Storms were increasing in intensity as they marched eastward.
REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE
FAVORABLE FOR SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND DO OCCASIONALLY DO PRODUCE TORNADOES.
LARGE HAIL AND DAMAGING WINDS WILL BE THE PRIMARY SEVERE STORM THREATS. AN ISOLATED TORNADO OR TWO CANNOT BE RULED OUT GIVEN THE POTENTIAL FOR EMBEDDED SUPERCELLS...BUT RATHER MODEST LOW-LEVEL MOISTURE FOR EARLY AUGUST AND A PREDOMINANTLY LINEAR CONVECTIVE MODE SUGGEST THE TORNADO RISK WILL REMAIN SOMEWHAT LIMITED.
Simulated radar reflectivity from HRRR model valid at 10 p.m.CDT
Thunderstorms are projected to arrive in the Twin Cities later this evening. Be prepared for potentially severe storms.
