Central Illinois is calling our name this evening.

At 1054PM, CT, Decatur was reporting clear skies with a temperature of 66 degrees. An active area of low pressure west of the Mississippi was drawing warm moist air north into Illinois, lending to the stuffy overnight temperatures, but a great deal of rain, with embedded thunderstorms was on it’s way. Fortunately, the warmer weather should continue through most of the day tomorrow.
The sharp curl to the upper jet will induce occlusion of the system through tomorrow morning, slowing the system down and taking the teeth out of the precipitation as it moves through Decatur. Severe weather, and even strong thunderstorms are unlikely. Wet weather will arrive in the evening in Decatur on Wednesday, with rain continuing, heavy at times through Thursday morning. Cooler, damp air will linger later in the day on Thursday as low pressure parks itself in central Illinois. With a murky upper level pattern, the lingering moisture over Decatur will help set the stage for shower and thunderstorm activity later this week.

Illinois looks nice on satellite, but those poufs of cumulonimbus west of Mississippi bear watching.
