The conditions are favorable for the development of severe thunderstorms across central Minnesota Sunday afternoon and evening, with a severe thunderstorm watch now in effect until 11 p.m. parts of western, central, and northeast Minnesota.
From the Storm Prediction Center:
"Thunderstorm development/intensification is expected the next few hours from southeastern North Dakota eastward into Minnesota. The storm environment will initially favor supercells with large hail and the potential for a tornado or two. Storms should grow upscale into clusters and line segments later this evening, when the primary threat will become damaging winds and hail."
Scattered large hail and isolated very large hail (up to two inches in diameter) are possible, in addition to the threat of 70 mph wind gusts. An isolated tornado or two are also possible.
Here's a look at the simulated future radar, which depicts what could happen (necessarily what will happen) between 4 p.m. and 11 p.m.
