A cold front will sag into Iowa later this afternoon then stall across the state tonight. The front will be the focus for strong to severe thunderstorms with large hail the main threat. Damaging will also be possible with a few storms. Although we may see a few non-severe thunderstorms north this morning, the severe threat will come after peak heating when the front sags into the state. Locations north of highway 30 and especially along and north of highway 20 will see the highest threat. Temperatures will be summer like with highs in the lower 80s north to the upper 80s and lower 90s south. Before heading out to evening activities, make sure you check the latest forecast and heed any warnings.
Low pressure will lift out of the Plains triggering additional thunderstorms in the afternoon and night. The best chance for severe storms will be across the west and north from late afternoon through at least the evening. Large hail and damaging wind will still be the main threat but a tornado threat will also occur near where the low pressure moves into. Make sure you check the latest forecast and warnings before heading out for the afternoon and evening.
