It could be a wild weather day across the southern half of Minnesota as strong and severe storms threaten to drop large hail and produce damaging winds.
Tom Novak of Novak Weather says he's closely monitoring thunderstorms in southeastern North Dakota. "As they continue to surge southeast, they will likely hold together and develop a squall line by mid-afternoon."
That squall line, shown as of 8:50 a.m. in the GIF to the left, could target the Twin Cities.
Novak will likely be taking over the Bring Me The News Facebook page early this afternoon for a live update on the situation.
The National Weather Service expects that the morning storms working their way into western Minnesota could hold together and pose a threat of producing large hail, but a secondary and more severe threat could develop along the I-90 corridor in southern Minnesota this afternoon.
"These storms could be quite feisty given the amount of instability they'll have to work with," the forecast discussion reads.
The Storm Prediction Center (SPC) has maintained an enhanced risk of severe storms in southern Minnesota, with the Twin Cities just north of the enhanced zone.
Storms that develop this afternoon could be quite intense, according to the SPC, which notes that the large hail threat could evolve into more of a damaging wind threat as the cluster/line marches east-southeast across southern Minnesota and northern Iowa.
Here's how things could play out if the HRRR model simulation is accurate.
Here's a graphic from the NWS's situation report, which says cloud-to-ground lightning will be likely along with the potential for large hail, damaging winds and a small chance for tornadoes.
