Stormy Start to Week

It looks like another stormy day in the Midwest. With probability forecasts from the Storm Prediction Center, let's break it down:

Tornado Probability
Here, 5% is the significant threshold. It includes KC, Des Moines, Quincy, Topeka and Omaha.

Damaging Thunderstorm Winds
Fifteen percent is the significant threshold for wind gusts of 60 mph or more. In the hatching, gusts of 75 mph or more are possible.

Large Hail
Again, 15% is the significant threshold for 1" or larger hail. Where you see the hatching, hail 2" or larger is expected.

And, for tomorrow:
This is the combined (tornado, hail, wind) probability map with 15% significant.

So, please keep up on the weather if you live in these areas!
