Feeling the Chill - You'll Notice the Difference in Temperatures Friday
A passing cold front Thursday night will be pulled back north as a warm front Friday afternoon. That front will stop short of northern Illinois during the day. Highs south of the front over central and southern Illinois will be in the 70's, or warmer. Highs north of the front will be in the 60's, with middle to upper 50's expected over northern Illinois and southern Wisconsin. Temperatures a couple thousand feet above our heads, however, will be warming quite a bit. Unfortunately that warmth doesn't quite make it down to the surface and will actually help keep cloud cover and even a little fog around through the evening.
