Cutoff Low to Bring Showers and Thunderstorms Today through Monday.


A cutoff low and cold front will bring showers and thunderstorms to the area today extending through Monday so read on for the full details…

Showers and thunderstorms will develop ahead of the cold front this afternoon/evening across northwest Iowa and slowly press east into central Iowa on Saturday. Eventually this wave will make it into eastern Iowa Saturday night through Sunday. Like a classic winter storm, this cutoff low will begin to wrap around moisture back into eastern Iowa on Monday which will provide additional scattered showers and thunderstorms. The activity should begin to taper off by later Monday night as the system slowly moves east of the state.

The area with the best lift and southeasterly flow from the upper level system will be across eastern Iowa. Now depending on how fast this upper level cutoff low phases with the main wave will determine how much rain will fall. So with that being said, some uncertainty exists on rainfall amounts. The ISC rain model below is calculating an average but it’s the best bet that I have to give you. These numbers can easily be cut in half if phasing happens faster.

Behind the front will be cooler temperatures and less humidity into next week. Even though the season isn’t quiet here, this front will be a (fall) cold front dropping low temperatures into the middle to upper 40s in northwest Iowa Saturday night through Monday night. The ISC rain model, rainfall timing and low temperatures are below.
