Rain likely Wednesday and tracking late week storm system; watch issued.


Rain is likely on Wednesday followed by a stronger system late week, read on for details.

Our first storm system will make it’s way into the state late tonight into Wednesday. We should start to see rain increase across western Iowa by later tonight and gradually spread out across the entire state Wednesday morning with the possibility of some snow mixing in across extreme northeast Iowa. Rain should begin to taper off across western Iowa by late morning, early afternoon across central Iowa and mid afternoon across eastern Iowa. This first round will bring a healthy swath of rain, especially to central and eastern Iowa. Refer to rain model below for accumulations.

Then by Thursday we will have a storm trough across the western United States and a ridge across the southeast United States which will put Iowa in the center for an active late week in terms of precipitation. We start off the event with heavy rain working into the state by Thursday morning. This activity should be fairly widespread through much of Thursday. Due to the heavy rain risk on Thursday…I have issued a Flood Watch for central and eastern Iowa effective Thursday through Friday and it reads; A strong storm system will impact Iowa between Thursday and Friday. This area does look to have the most lift to trigger heavy rains on Thursday. Preliminary rainfall amounts will be in the 1-2″ range across the watch area. Enough instability may be available to allow for a few storms to have some hail and gusty winds with them later Thursday afternoon. Then strong wind gusts over 30+ MPH will impact the watch area on Friday. A flood watch means that conditions are favorable for flooding with heavy rainfall in a short period of time.

Later Thursday evening rain will likely change over to snow across northwest Iowa and gradually work into north central Iowa by Thursday night into Friday morning. Strong wind gusts will also be likely later Thursday afternoon across NW Iowa with the threat moving east into much of Iowa on Friday. Snow accumulations look to be light to moderate across northern Iowa. I will continue to monitor Thursday/Friday and will update you as needed.
