Fabulous Sunday on the Way

A strong disturbance associated with a fresh shot of Canadian air is centered over eastern Wisconsin early tonight.  It caused some showers to pass across north central Illinois earlier this evening.  Those showers have since move eastward out of the area, and are over southern Lake Michigan at 11:45 pm Saturday night.  The clouds will break up, and it will become mostly clear overnight.  It will be breezy with a northwest wind at 10 to 15 mph.  The low tonight will be around 50 degrees.  After a cool start on Sunday, temperatures will reach into the comfort zone in the afternoon.  The high will be in the low 70's with  a brisk northwesterly breeze.  There may be a few cumulus clouds, but it will be a mostly sunny day with blue skies and low humidity.  The Canadian high will move to Wisconsin early on Sunday night.  It will be clear and cool overnight with light winds.  The temperature will drop into the upper 40's.  The center of the high will move to southwestern lower Michigan by early on Monday morning.  With the high still in control of area weather, it will be sunny, and the high will be in the middle 70's.  On Tuesday the high will move to Pennsylvania, but will still be in control of Stateline weather.  A southwest wind will develop across the area, and temperatures will  rise into the low 80's under sunny skies. It will still be sunny on Wednesday, but temperatures will continue to warm under a southwesterly wind flow.  It will be warm with a high in the middle 80's.  In fact, that forecast may not be warm enough because the dry soils in the area from the ongoing drought will warm up fairly easily, so it is possible that temperatures could be close to 90 degrees again on Wednesday.  A front will move into the area from the northwest on Wednesday night.  There is a slight chance of showers as the front moves into the area overnight. It will be mild with a low in the low 60's.  On Thursday the front will be slowly edging through the area, temperatures will be cooler, and there could be some showers and thunderstorms Thursday and Thursday night.  Cooler air will follow in behind the front.  High temperatures will drop back into the 70's for the end of the week into Saturday.  Cool unstable air aloft could fire off some scattered light  rain showers Friday and Saturday.
