A warm up before the cool down

The 60° temperature trend will continue for a couple more days before the low 50s round out the work week.  A cold front passed late Sunday evening generating a line of showers/storms that moved through southern Wisconsin and northern Illinois.  Behind the front a more dry and 'cool' air mass will be found but temperatures today should be able to rise back into the low to middle 60s. 

The next weather maker is already moving onshore in the Pacific Northwest and we'll begin to see the effects of it beginning tonight.  Clouds will continue to increase as warm and moist air move in from the south aided by a pretty strong low level jet.  It's possible that showers and maybe a few embedded thunderstorms will form north of the Wisconsin/Illinois border during the overnight and early Tuesday.  As it looks right now the warm front will sit just to our north keeping us with a southerly wind while a northeast wind will be found further in Wisconsin.  We should be able to squeeze out some sunshine during the afternoon and that will be enough to bump temperatures into the upper 60s across northern Illinois, with a few cities to the south squeezing out the low 70s.  North of the front temperatures will be held in the low 60s thanks to cloud cover and showers.  The low pressure and associated cold front will pass during the evening shifting winds more north/northeast once again pulling down a cooler air mass that will be in place through the end of the week.
