A strong low pressure system will move out of the plains today and move into Iowa. Storms will develop and move into Iowa this afternoon. Showers and storms remain to our west today, but we will see some of the cloud cover from these storms this afternoon.Dew point numbers will be on the increase tonight and tomorrow, into the low 60's, as moisture begins to move northward. A warm front will be to our west today and tonight, but will be brought northward through the area, due to low pressure moving into Iowa. As warm air moves over the warm front, instability will begin to grow.
The first chance for rain arrives Tuesday morning around daybreak, with energy arriving ahead of the low. This round doesn't have much of a severe weather threat, but could produce heavy rain. Showers and thunder could linger into the late morning, with a midday break from rain possible. What happens with the storms tomorrow morning though will have an impact on what happens in the afternoon. Depending on the coverage of rain and storms tomorrow morning and how long they last, it could limit the severe threat in the evening. Right now there will still be enough instability to hold onto the strong storm threat, as storms develop in Iowa tomorrow midday and track east into Illinois.Right now there is a slight risk for severe storms in place for northern Illinois and southern Wisconsin, along with central Illinois, portions of Missouri, and southeast Iowa. If the severe threat holds, the storms could produce hail, gusty winds, and heavy rain. Right now the timing is forecast around 4pm through the evening, with the threat diminishing overnight.
If the low pressure track moves south, then the severe threat could shift south too. However, we want to watch the potential for heavy rain too, with rain totals near .50-1.50" possible.
