Today:
A progressive cold front is forecast to spark an area of scattered to numerous severe thunderstorms beginning over the western Dakotas this afternoon and working eastward.
Initially, development should promote the threat of very large hail and some tornado risk before upscale growth occurs this evening with a transition toward primarily damaging winds.
Further south, a secondary area of interest extends from central Nebraska to northwest Iowa, but uncertainty remains regarding severe development.
However, should storms be able to break the cap this evening, a highly unstable environment would support all severe risk hazards from the late evening into the overnight period.
Wednesday:
The cold front will slowly advance eastward, with a secondary area of heightened severe weather stretching from Minnesota/Wisconsin southward into Iowa.
While some uncertainty exists regarding the coverage/placement of the initial development due to overnight activity, some adjusting with the higher risk zone may be needed downstream.
Nonetheless, a focused risk for large hail over 2 inches in diameter, damaging winds potentially over 70 mph, and isolated tornadoes will be probable during the afternoon through the evening.
