That pesky old upper-low is still sitting and spinning over northern Illinois today, and it will inch it's way to southern Lake Michigan by evening, and wobble around that area overnight into early Wednesday, keeping the showers going for the Stateline. It produced record amounts of rain yesterday with a total of 3.93" at the Rockford airport. No heavy rains are anticipated today with the system losing a lot of it's punch, having rained out most of it's moisture. Highs today will be held down to near 60 degrees with the cloud cover and rain showers. Expect scattered light showers tomorrow with a high near 67. A strong cold front will blow through the area on Thursday. Temperatures could reach 70 degrees before falling off during the afternoon. There will be a slight chance of showers with the front, but nothing significant is expected. On Friday a post frontal trough of low pressure could generate some instability showers, but once again only light scattered amounts are expected. Canadian high pressure will clear skies, and drop temperatures on Friday night, as it settles southeastward to near Eau Claire, Wisconsin by 6 am Saturday. It may be cold enough for scattered frost late Friday night into early Saturday morning with a low around 37 degrees. It will be sunny, but chilly on Saturday with a high only in the upper 50's. It will be clear and cold again on Saturday night with a low near 38 degrees. Sunday will be sunny and warmer with temps topping out near 67 degrees.
