Today's Tornado Risk

On this first day of astronomical autumn, we have a springlike weather situation with tornadoes, giant hail and damaging thunderstorm-generated winds all possible.

Note: there are thunderstorms roaming parts of this area right now. This does not affect the forecast below which is for after 2pm this afternoon and evening. 

Tornado Risk
The brown area has a significant risk of tornadoes. However, there are indications the may be a somewhat higher risk in southern Minnesota and northern Iowa.

Giant Hail
The hatched area is where hail 2 inches or more in diameter is forecast to fall. Elsewhere in the yellow area 1-2" hail is forecast with a significant risk. The red area is at an enhanced risk level.

Damaging Thunderstorm-Generated Winds
The yellow area has a significant risk of thunderstorm winds of 60 mph or stronger. The red area has an enhanced risk.

I will provide an update this afternoon.
