The National Weather Service has issued a severe thunderstorm watch for pretty much all of southern Minnesota as a line of storms races across the state during the morning and early afternoon hours Thursday.
The watch was issued at 4 a.m. and is in effect until 1 p.m., with the primary threats being damaging winds with isolated significant gusts to 75 mph possible. Isolated large hail and a tornado or two can't be ruled out.
The line of storms will produce very heavy rain and frequent lightning. Some areas could pick up 1-2 inches of rain.
A second line of storms later Thursday?
Once the line of storms moves through by midday, there could be more nasty weather if a second cluster of storms develops late in the afternoon or evening.
The National Weather Service in the Twin Cities isn't sold on it happening just yet, but the Storm Prediction Center (SPC) has areas of eastern and southeast Minnesota, including the Twin Cities, under a slight risk for severe storms.
The HRRR model (GIF may not load in all browsers) shows the first wave of storms moving through by midday, but then another cluster developing northwest of the Twin Cities and diving southeast.
Again, the first line of storms may stabilize the atmosphere enough to limit any new storm development this evening. The SPC will have a better understanding of what could happen once the first line of storms moves through.
