A strong storm system will move through the area later today bringing strong to severe storms and a wintry mix so read on for the details…
Scattered rain showers will continue to work east across the state this morning. Behind this line will be an area of severe storms that will develop across west central and southwest Iowa. All modes of severe weather will be possible in these areas including damaging winds, hail and a few isolated tornadoes. Given the shear profiles, a few isolated tornadoes look feasible with the main risk from southwest Iowa and points east into the center part of the state. This risk should transition more to a damaging wind event later tonight as the line will move east into eastern Iowa.
Cold air will be wrapping around on the backside of the system to aid in some wintry mix/snow across northwest Iowa later this evening. I can’t rule out a quick trace-2″ of snow accumulation in these areas but that would be about it. In addition to the precipitation, we will have gusty southerly winds especially in the severe weather prone zones with the wind switching around to the west/northwest by later tonight into early Sunday morning. The strong gusty winds will subside by daybreak Sunday as the system will pull to the east of the state.
An additional storm system will move through later Sunday night into Monday with a round of accumulating snow for a good portion of the state. It’s too early to discuss amounts just yet but this is a light to moderate wave of snow on the table with the highest amounts across south/southeast Iowa. I am also watching for what can be another round of snow this coming Thursday but we will discuss this more in future updates. Refer to the graphics below for areas affected today through Monday.
