Strong storms hit Twin Cities, Ironwood; heavy rain in forecast

The risk of severe weather over the Northland on Monday night was slight, and as it turned out the atmospheric conditions never came together for strong storms over most of the region.

The Twin Cities got socked by a few severe storms very early this morning. Ping-pong-ball-size hail was reported at Mahtomedi and near St. Paul shortly before 2 a.m., with quarter-size hail at the Minneapolis-St. Paul International Airport at about 1:40 a.m. Strong winds brought down branches and some power lines; several hundred homes were without power this morning, according to Minnesota Public Radio.

Those storms moved northeast and prompted a severe thunderstorm watch for Northwestern Wisconsin and the western Upper Peninsula during the early morning hours. A severe thunderstorm warning was issued for southern Washburn County shortly before 3 a.m.

There was some damage reported in the far eastern parts of the region. Penny-size hail was reported at Hurley, in Iron County,  at 4:20 a.m. Shortly after that, penny-size hail and wind damage was reported across the Montreal River in Ironwood, Mich. The National Weather Service in Marquette said spotters reported “widespread trees and power lines down across Ironwood” at 5 a.m.

Looking ahead, the region may be in line for some very heavy rainfall on Thursday. Here is the latest hazardous weather outlook from the National Weather Service in Duluth:

As you can see, the Northland – especially Northwestern Wisconsin – is at a bull’s-eye for heavy rain. Of course, things may change over the next couple days, so keep an eye out for forecast updates.
