A slow moving front will keep storm chances around through Friday as temperatures remain seasonable. A few storms along and north of Highway 30 tonight could be strong to severe. After Friday, conditions begin to dry out heading into next week.
A cluster of storms is forecasted to impact the Highway 20 corridor in Iowa tonight before weakening as they move south towards the I-80 corridor into Thursday morning. A few of these storms north of Highway 30 could be strong to severe with the primary hazards being gusty winds, lightning, and heavy rain. Additional storm development is possible Thursday afternoon, but the severe threat is low.
A pattern change early next week could bring above normal temperatures (40-60% chance) and below average precipitation (33-50% chance) to the region as ridging sets up overhead.
