May 30 Thunderstorms

Isolated showers and thunderstorms are likely throughout much of the afternoon and into this evening over the state. Some of these are already ongoing with extensive cloud cover that worked over the state late last night. The severe threat previously was thought to be fairly low, however with the advancement of a upper level system northward today is allowing the severe threat to increase. Much of Iowa has been put under a slight risk by the Storm Prediction Center in their latest day 1 outlook. The threat for damaging winds along with some isolated spin-ups is possible this afternoon/evening ahead of the cold front. The SPC has also put out a Mesoscale Discussion for portions of extreme northwest Iowa, a severe thunderstorm watch may be issued this afternoon. For more details on the possible watch, see MD #929.

5:15 PM Update: A line of thunderstorms is currently moving across central Iowa, slowly northeastward. Behind this main line of thunderstorms, in the north there are a couple other small line segments to make their way over, otherwise the rest of the state will see clouds begin to clear out. Severe weather is no longer expected at this time over the state...
