Hey, I’m back! It’s been a while, which is pretty strange, I guess. Off to northern Illinois for my first forecast of the week.
At 915PM, CT, Kankakee was reporting clear skies and a fairly muggy 68 degrees. A sharp but rapidly diminishing wave moving through the Upper Midwest was responsible for the moisture across the region, and was producing a persistent swath of rain northwest of a line from the Quad Cities to Rockford. Expect a dry night for Kankakee for tonight, however the trough will get folded into a weak upper level perturbation and begin to shift eastward tomorrow afternoon.
The boundary will work its way through northern Illinois tomorrow, which may lead to a stray shower or thunderstorm, though widespread precipitation is not anticipated. The shear associated with the trough will deteriorate, and a weak ridge in the Appalachians will lead to the remnant energy to stall in the western Great Lakes and lower Ohio Valley. This will mean a mostly cloudy Sunday, but with cold air not available, it should remain rather stuffy.
Tomorrow – Scattered showers, with an isolated thunderstorm, High 80, Low 63
Sunday – Mostly cloudy, but warm, High 84, Low 63
TWC: Tomorrow – Scattered Thunderstorms, High 81, Low 61

It will be interesting to see how much of that lingering moisture actually hangs on for Sunday. I suspect with temperatures warming, the cap will be strong. Take a look at the current radar, with all the rain to the northwest.
