MINNEAPOLIS (WCCO) — Prepare for back-to-back Next Weather Alert days, as severe storms that could produce tornadoes are possible Wednesday and Thursday. There’s also extreme heat in the forecast.
Two batches of thunderstorms are making their way through the state; one system covering Brainerd through the west metro is moving to the northwest. A severe thunderstorm warning for Carver, McLeod, and Wright Counties says there’s potential for quarter-sized hail to drop until 1 p.m. The Marshall area is also under a severe thunderstorm warning with threat for golf ball-sized hail.
Thunderstorms could roll through the metro around 8 p.m., bringing damaging winds.
A warm front is going to lift throughout the day, which will bring in heat and humidity. Temperatures and the dew point will rise as the day rolls on, with the high in the Twin Cities forecasted at 83 degrees. It’ll be a few degrees warmer to the south, and central and northern Minnesota will top out in the 70s.
Next Weather Alert: Hail, Damaging Winds & Possible Tornadoes
The WCCO weather team said storms will develop in southwestern Minnesota between 3 and 4 p.m., then move northeast across the state. The southwest is under an enhanced risk for severe weather, and that’s where the tornado threat is greatest.
As the storm system moves northeast, the threat will turn to heavy rain and large hail. The system should arrive in the Twin Cities around 5 p.m., then move into northern Wisconsin later in the night.
Flooding is also possible overnight.
We’ll take a little breather Thursday morning, then another round of severe weather is possible starting in the afternoon. The greatest storm threat will be from west-central to northern Minnesota.
Thursday will be flat-out hot and humid, with a high of 90 in the metro. It will also be a very windy day. It will all settle down Friday, and it should be a calm and humidity-free fishing opener weekend, with temps in the 70s.
