Severe outbreak coming to Midwest, Great Lakes
After a relatively calm week, it looks like severe weather will return to the Great Lakes this weekend, with a potent storm system rolling through the region the next few days, including the threat for strong winds, hail and tornadoes, along with flooding in areas that don’t need any more rain.
A slow-moving low pressure center could wreck havoc on the eastern two-thirds of the country (the northern half) from Friday through as late as Tuesday. Severe weather will start in the Dakotas on Friday and then push into Minnesota and Iowa on Saturday, then into Wisconsin, Illinois, Indiana and Michigan for Sunday before affecting the east coast to start the work week.
With heat (temperatures in the 80s and low 90s) and plenty of humidity (dewpoints in the low 70s) to fuel these storms, Saturday and Sunday look like they could feature the worst of the severe weather.
Vorticity (atmospheric spin) is going to affect these storms and we’ll be looking at the threat for damaging straight-line winds, large hail and, yes, tornadoes – particularly in Minnesota, Iowa and Wisconsin.
With this potential outbreak targeted for the last weekend in June, the concentration of the severe weather will be concentrated a bit further north than your typical trouble zones.
Another threat to obviously keep in mind is flooding. With Minnesota, South Dakota and Iowa blasted by a series of soakers the last few weeks, this round of storms could be enough to trigger some even more serious flash flooding once again, particularly in the Twin Cities.
