Feisty T-Storms overnight; Hancock tornado confirmed

Midnight Light Show

The latest wave of T-Storms races across Minnesota into Wisconsin overnight. Expect lightning, downpours, gusty winds approaching 50 to possibly 60 mph and some hail as the storms roll through the Twin Cities in the hours surrounding midnight.

The storms have a history of severe winds over 60 mph in western Minnesota. Once again, radar images show that classic bow echo bulge moving through Minnesota. Bow echo signatures on radar often produce damaging wind gusts.

These storms are electrically intense. The advancing storm wave is cranking out a solid wall of cloud to ground lightning strikes as it sweeps east. It’s going to be a bright and loud night. I won’t be shocked to hear about lightning hitting some homes and starting fires overnight. Fingers crossed it’s a safe night for all.

Tornado threat lingers

A tornado watch continues until 2 am for much of southern Minnesota. Brief tornadic spin-ups along the leading edge of the storms called “Gustnadoes” are a possibility overnight. Gutnadoes can still do damage.
