It’s a storm system that just won’t quit. A frontal boundary swinging through the state is bringing large temperature and humidity swings to the area as well as the threat of strong thunderstorms. As you can see in the temperature snapshot to the left, temperatures range from the 70’s to 90’s across Iowa right now.
This frontal boundary may trigger some showers and thunderstorms tonight. An isolated storm or two may produce large hail and/or strong damaging wind gusts, but no organized threat is expected.
The chances of severe weather increase slightly on Tuesday, as the frontal boundary continues to linger over the state. Right now the best chance for rough weather exists in eastern portions of Iowa. We’ll monitor this threat for Tuesday but again I don’t expect much in the way of severe weather.
Besides the severe threat, it looks like most areas will get in on prolonged periods of rain. Heavy rain does not appear to be a serious threat this week but it’s certainly something that needs to be watched, especially on the local level.
As for the rest of the week, this storms system sticks around until at least Friday. The best chance for strong storms this week comes on Thursday. But for now, the threat is difficult to nail down and we will just have to wait and see what happens. In the meantime we’ll keep a close watch of tomorrow’s threat which could turn into a wind and hail storm kind of day, similar to the weather we saw Saturday evening.
