Today was a beautiful day with highs reaching into the lower 70’s with abundant sunshine! This is because we are under an area of high pressure which has kept us dry. This weather pattern will last one more day into Tuesday, but by Wednesday, the pattern will begin to change.
Storms will then enter into the central Iowa region around 4pm and will continue to push off to the southeast. A few of these storms may be capable of producing some hail due to the marginal CAPE (convective available potential energy) that will be in place ahead of these storms. Because of this, the Storm Prediction Center has placed the western half of Iowa under a marginal risk of severe weather.
There is some uncertainty around the severe potential though as overnight storms that move out of South Dakota may have an impact on destabilization. If enough instability does not build back into the state, then the severe threat will be lowered.
This active period will continue into the weekend with rain chances likely on Thursday and Friday. It does appear that we will get a break in the rain on Saturday as most of the day should be dry with partly sunny conditions. However, this will be a short break as more rain moves back into the forecast by Saturday night into Sunday.
