Keep the umbrella handy Wednesday, especially in the late morning and evening. We're watching a couple chances for rain today, the first will be arriving a little before lunch today. A mid-level disturbance is firing up an area of rain and storms in southeastern Iowa. This will weaken but will move into northern Illinois closer to 10am this morning and will continue through lunch today. We are not anticipating any severe weather with this first round of rain.
Most of Wednesday will be dry, but more storms will be possible this evening. An area of low pressure will trigger a warm front to lift across northern Illinois and Iowa, and will trigger storms to develop in western Iowa around 3-4pm. The storms will move east bringing the threat for an isolated tornado, large hail, and strong damaging winds through central and eastern Iowa. This has prompted an enhanced risk for storms (orange color) from central to eastern Iowa. Northern Illinois and southern Wisconsin are under a 'Slight' risk for strong to severe storms (yellow). Our storm threat will be more isolated in nature as the larger MCS type system lifts north of the area. However, thunderstorms across our region have the potential for larger hail and gusty winds as well.
The threat for these storms will increase after 8pm tonight, with higher chance closer to the 10pm hour. It will be a good night to keep the car in the garage! The rain won't last long, we'll dry up by early Thursday morning.
