Severe storms that are expected to develop in North Dakota on Tuesday will likely congeal into a line of storms that will race from northwest Minnesota through central and east-central Minnesota overnight into Wednesday morning.
Storms will be at their strongest, possibly producing damaging winds and large hail bow-echo, as they cross the North Dakota-Minnesota border before gradually weakening into central and eastern Minnesota.
The line of storms should be below severe limits by the time it reaches the Twin Cities area, although a strong or severe warning isn't out of the question.
The National Weather Service expects the storms to arrive in the metro sometime before Wednesday morning's rush hour.
Wednesday's severe threat will likely be limited to extreme southern Minnesota into Iowa due to lingering cloud cover from the early-morning storms, the NWS says.
That said, most of southern Minnesota, including the metro area, is under a slight risk for severe weather on Wednesday.
