Stormy Monday: ‘Enhanced’ severe weather risk late today

It looks like an active afternoon on Doppler radar and in Minnesota skies.

A cold front slices into a warm and humid air mass across southern Minnesota Monday. An upper-air wave racing east from the northern Rockies into Minnesota will trigger storms by late afternoon. The storms will likely pack heavy downpours, high winds, and hail as they rumble east.

Keep an eye and ear out for watches and warnings late Monday.

Bottom Line: Stay situationally aware for the risk of severe weather late this afternoon and evening. Stronger storms could produce wind and hail damage. Flash flood risk is there from the Twin Cities east into Wisconsin.

Cool front

The front triggering today's storms will bring much cooler and more comfortable air into Minnesota this week. Highs in the 70s return this week. Temperatures warm again to summer-like levels as we move toward September.
