Day 2 Moderates

21 May 2024 05:30 AM
The Storm Prediction Center issued a Day 2 Moderate Risk yesterday for most of southeastern Iowa on Tuesday. The featured map presents a heat map of such risks expressed as average number of days per year at such a threshold. Much of Iowa is shown around the one day per year frequency with the highest frequencies found over Arkansas into Mississippi. The afternoon storm threat is conditional on how the morning storms play out and what surface air mass boundaries they create for later afternoon storms to deal with. All of the severe weather threats of large hail, damaging winds, and tornadoes are expected throughout much of the day and into the evening.
