Our next storm system will move through the area tonight through Wednesday with rain and snow dynamics so read on for the details…
Mild temperatures will continue today with highs generally in the 60s/lower 70s and gusty southwest winds across much of the state. A surface low will develop near the Texas panhandle later today which will lead to a cold front that will push a wave of rain across the state from west to east tonight through Tuesday. I even see the possibility of a few rumbles of thunder in the southeast part of the state given instability and lapse rates. Behind the front, temperatures will crash into the 30s so rain on the backside of the main wave may have some snow mixing in across western Iowa. In addition to the precipitation, gusty northern winds will be common across western Iowa on Tuesday.
The speed of the system will slow down later Tuesday night as additional pieces of energy from the main storm system wrap around. This will pose the risk for some rain/snow showers and gusty northerly winds for much of the state on Wednesday. Additional snow showers may occur Thursday before the storm system will move east of the state. This is your Wind Advisory from me that will go into effect for western Iowa on Tuesday and then all of Iowa on Wednesday when the strongest winds will hit.
We are looking at a decent swath of rain with 1.0-2.0″ for most of the state and 0.5-1.0″ in interior northwest Iowa. Locally higher rain amounts exceeding 2″ will be possible generally south of I-80 in south central Iowa near the trough axis and upper level low. Snow accumulations will be generally 0-2″ on grass and elevated surfaces for much of Iowa. Use the images below for rain and wind.
