UPDATE: 9:28PM. We are now receiving reports of measured wind gusts of 70 mph in central Iowa.
At 9:26 pm the thunderstorms are rapidly intensifying. People in the path of these storms need to be prepared for very high winds. Here is a new severe thunderstorm watch ahead of this line.
I'm not liking the look of the thunderstorms developing over Iowa.
First of all, the values of "downdraft CAPE" (don't ask) are extremely high. If the storms fully develop, these values support gusts above 70 mph.
Second, organized thunderstorms are already developing AccuWeather regional radar shows these as of 9:55pm CDT
Severe thunderstorm warnings are in effect for high winds and hail in central Iowa. Maroon = severe thunderstorm watch.
