Heavy Rain and Severe Weather Possible Friday

Rain has been on the increase this afternoon, and will continue to spread to the north throughout this evening and on into Friday. Heavy rain appears likely across a large portion of the state, with a few severe storms possible, mainly across southwest Iowa.

The Weather Prediction Center has placed much of Iowa under a slight risk of excessive rainfall. This is because 2 to 4 inches of rain will be possible. This may create a flash flooding threat, in low lined areas.

There may also be a window for surface based convection and severe weather across western Iowa. This would introduce some wind and hail potential and depending on where the weak surface waves along the inverted trough develop there could be sufficient warm frontal development and low level backing to boost the shear for brief tornado potential. While October tornadoes are more uncommon in Iowa, on average, we typically see one tornado every October as outline in the map below.
