Tommy's Travel Forecast: Multiday outbreak of severe weather

AUSTIN (KXAN) -- A severe weather outbreak is brewing in the Upper Midwest, set to impact millions in the coming few days. There is the potential for intense tornadoes, straight-line damaging winds, and large hail.

On Monday, a level 4/5 moderate risk has been issued for portions of Iowa, Minneapolis, and Wisconsin. Major cities such as Minneapolis are in the 'bullseye' for severe weather.

A positive-tilted, upper-level trough is the textbook setup for widespread severe weather in the Plains and Midwest.
