Much Cooler Weather for Friday and Saturday

A strong cold front moved east across northern Illinois on Thursday afternoon. After topping out at 73 degrees before the passage of the front, the colder air pouring in behind the front has dropped temperatures down into the middle 50's as of 5 pm cdt. There were a few light rain showers with the passage of the front, but only a trace was reported at the Rockford airport. A thundershower moved across northern Lee county to near Rochelle, and further off to the northeast across central De Kalb county. A heavy shower was moving through the De Kalb area at 5:15 pm.   As of 10:30 pm a line of narrow line of showers and thunderstorms extended from lower Michigan, northeastern Indiana, to just north of Champaign, Illinois, and then west across central Illinois through Springfield into central Missouri. The line was moving toward the east/southeast away from the Stateline.  Skies have cleared, and drier air is moving in from the west.  Temperatures will drop into the middle 30's.  No significant precipitation is expected in the north central part of Illinois for the next week.  It will be pretty chilly, too,  for the next couple of days.  Canadian high pressure will ridge into the midwest on Friday.  It will be partly cloudy, breezy, and much cooler with a high in the middle 50's.  Temperatures will drop to near 30 degrees on Friday night, and with a cold northerly air flow on Saturday, the high will only be in the upper 40's.  The high will move to Kansas early on Saturday night, and to Kentucky by early Monday morning.  The low will be in the upper 20's under clear skies.  On Monday, with the high off to the east, the wind will become southerly, and temperatures will warm back up into the low 60's.
