Active Weather Day Wednesday

Wednesday will be a very active weather day is expected across the state as two rounds of storms are forecast to impact Iowa. The first round of storms will develop over western Iowa late tonight and spread eastward throughout the overnight hours.

Storms will begin to enter northwest Iowa around midnight this evening. These storms should be in a bowing segment, which will pose a damaging wind threat. Wind gusts could be in excess of 70-mph. Storms are then forecast to push into eastern Iowa by the mid-morning hours Wednesday.

The second round of storms looks to develop during the afternoon hours, especially over central to southern Iowa. Storms should develop after 3pm Wednesday, and appear to struggle to stay isolated. The initial cluster of storms that develop across central and southern Iowa Wednesday, will include all modes of severe weather, including a few tornadoes.

Storms will eventually merge as they advance into eastern Iowa, which will lessen the tornado potential, and increase the damaging wind potential. Even though storms in eastern Iowa will mainly be wind and hail producers, an isolated embedded tornado can not be ruled out, especially if any storms interact with leftover outflow boundaries from Wednesday morning storms.

We fully expect the Storm Prediction Center to upgrade a portion of the severe weather outlook by Wednesday morning, so continue to check back to the Iowa Storm Chasing Network for the latest severe weather updates.
