A cool ridge of high pressure stretching from Canada across Lake Superior, western Wisconsin, Iowa, and Missouri will settle down across the Stateline overnight. The skies will be clear, and with near calm winds and dry air, the temperature will fall to near 40 or into the upper 30's by daybreak. The high will shift quickly off to the east on Saturday, and the winds will switch to the south, and pick up in advance of the next front moving southeast across the plains. There will also be a nice warmup into the low 70's by mid afternoon under sunny skies. The atmosphere is so dry, and the Gulf of Mexico will be completely cut off so that when the cool front passes through the Stateline late in the day there will not even be many clouds. It will be mostly clear overnight on Saturday night, and with cooler air pushing in from the north the temperatures on Sunday, will top out in the low 60's. The front will stall out in central Illinois on Sunday, and a disturbance will move along the front out of the plains on Sunday night and Monday. There is very little moisture available, but with good lift to the north of the front is appears as if we will see fairly widespread light rain on Sunday night and Monday. Not more than a few hundredths of an inch is anticipated at this time, so our dry weather pattern will continue. With lots of clouds and a north to northeast wind on Monday it will be chilly with highs only in the upper 50's. Despite mostly sunny skies on Tuesday, but it will continue to be cool with a high again only in the upper 50's. There will be a slow warm up under mostly sunny skies for the rest of the week taking temperatures back into the upper 60's by Friday afternoon.
