The next storm system is set to target Iowa early next week with showers/thunderstorms and severe weather potential so read on for the details…
A deep trough and low pressure system is expected to develop across the western United States on Monday. Ahead of this system will be a cold front that will sweep through the state Sunday which may bring some scattered showers to the eastern part of the state by the evening time frame but that will be about it with this first one. Then the main system will start with a warm frontal zone setting up just south of state by Tuesday morning. The early thinking is that the warm frontal zone will advance to the north into Iowa which will lead to temperatures surging in the 60s and 70s for highs Tuesday. The details after this become very scattered and a lot of fine tuning is needed but a severe weather risk may exist later Tuesday afternoon/evening across a good portion of the state.
Once Wednesday hits, the warm front will extend across southern Minnesota which will make the atmosphere primed for a second round of severe weather. This should lead to a decent amount of instability and dewpoints in the upper 50s to lower 60s. The timing on the cold front and surface low location will be the key players as to what exactly goes down on Wednesday. I usually draw up my own outlooks but I do believe the Storm Prediction Center is handling this well at the moment so I have attached those graphics below. As I mentioned above, a lot of details still need to be worked out so make sure to check back for further updates.
