A weak ridge of high pressure will continue to provide the area with mostly clear skies and light winds overnight. With dew points this evening near 20 degrees, temperatures will drop down to seasonal averages in the upper 20's. Skies will be mostly sunny on Tuesday in the morning. The ridge of high pressure will slip off to the east in the afternoon, and winds will bcome southwesterly pushing temperatures into the upper 50's. A weak cool front will push through the area on early Tuesday evening. It's passage will go virtually unnoticed because the air is so dry that no rain is expected. Only a few clouds will be produced by the front as is moves through northern Illinois. Weak high pressure will follow in behind the departing front later Tuesday night and Wednesday. So, with dry air in place it looks like mostly sunny skies along with a light northeasterly breeze on Wednesday. Another cold front will drop southward across the area early Thursday morning. Once again, because of the dry air in place, no precipitation is anticipated. The air behind this front will be colder, though, with high temps on Thursday dropping back down into the 40's. On Thursday, a low pressure storm system will develop in the southern stream. This stream has been predominate for most of the winter. It's track is not certain at this time, but it is expected to move across southern Illinois. At this time it looks like it may spread rain as far north as Interstate 80, Thursday and Thursday night, with the cloud shield reaching northward into the Stateline area. On Friday a cool northeasterly breeze will develop across the Stateline from a chilly Canadian high pressure center north of the Great Lakes. It looks like, despite plentiful sunshine fon Friday, that temperatures will top out in the mid to upper 40's. It will remain mostly sunny on Saturday as the Canadian high and ridge shift off to the east. Winds will pick up from the south on Saturday hoisting afternoon temperatures back into the mid to upper 50's. The next cool front in this progressive pattern will approach the area on Saturday night bringing a chance of rain Saturday night and Sunday. A fairly strong low pressure storm system will whip itself up over Missouri on Saturday night, and move quickly eastward across the area on Sunday ending the precipitation on Sunday night. Another cool ridge of Canadian high pressure will take control of our weather on Monday keeping our daytime temperatures in the 40's.
