Midweek Severe Weather Threat

day2otlk_0600After a break from the rain today, the threat of severe weather returns to much of Iowa on Wednesday.  You can see the broad area under a slight risk for severe weather in the graphic to the left.  Storms are expected to develop north and west of Iowa tonight, possibly reaching the extreme northwest part of the state during the morning hours of Wednesday.

These storms could intensify or a new round of storms could develop near a frontal boundary.  These storms have the capability of producing strong, damaging winds, large hail and tornadoes.  This storm system is certainly one that bears watching as it gets closer to Iowa.

We’ll continue to monitor the latest outlooks, but it’s clear storm chasers and spotters need to prepare for a rocky night on Wednesday as this storm system makes it’s way through Iowa.  We’ll have an update this afternoon once new data is in on the threat facing the state tomorrow.
