Storms over central Iowa will generally move east arriving into eastern Iowa along the I-80 corridor to near Highway 30 toward midnight into the early overnight . Some strong to severe storms are possible.
There is a slight (2 out of 5) risk for severe weather tonight along/north of I-80. Primary threats include large hail up to golf ball-size and gusty winds. Have multiple ways to receive warnings, especially since these storms will occur overnight!
There is also a marginal (1 out of 5) risk of severe weather Tuesday afternoon into Tuesday evening as a cold front moves through the area. A few storms could produce quarter-sized hail and damaging winds upwards of 60 mph.
Multiple rounds of storms will roll through the area this week. There is a medium/high chance for 2+ inches of rain by Saturday morning with the highest amounts falling Wed night into Thur, where there is a low-end chance of flash flooding.
Before the drenching rains later this week, dry air in place and gusty winds will keep the fire risk across the region elevated through Tuesday. Use caution when operating outdoor equipment and delay any burnings, if possible.
