SPC Center Public Severe Weather Outlook (PWO)
These storms bring the threat for high winds, damaging hail, heavy rains, and isolated tornadoes. If severe weather does strike early tomorrow morning, stay in a sturdy structure, and stay away from the windows.
Sunday, a slight risk for severe weather is present over much of central and southern Indiana. Temperatures will only fall into the low 70s Monday morning. The greatest risk is from late afternoon into the evening and early nighttime hours, roughly 4 PM to midnight.
Major cities that are under the gun include Des Moines, Rochester, and Minneapolis. Rainfall could total 1-2 inches. Using their criteria, this means 75 miles per hour plus wind gusts, along with supercell thunderstorms that could produce strong tornadoes.
The 30% area is an ENHANCED RISK and includes most of Kentucky and Indiana.
Timing The Storms. Although strong storms are rumbling across Northern Minnesota the main event initiates this evening.
Thunderstorms will begin to fire in central Minnesota and drop south as the evening progresses.
Summary: it’s been a relatively quiet severe storm season so far across the Upper Midwest, but that’s about to change. Right now the most likely place for the storms to start is Wisconsin. On the eastern edge of this hot air is where a complex of severe storms is expected to develop Monday.
