The Big Low is Finally Moving on Out of the Area

That upper-low that bought us the heavy rain on Monday has shifted a little eastward, and is located over extreme southwest lower Michigan this morning.  Clouds continue to rotate around the low through north central Illinois.  With much of the moisture wrung out of the system, only light scattered showers will affect the area today.  Drier air is breaking up the clouds across Wisconsin, so skies are expected to become partly cloudy today.  High temperatures, with the help of some sunshine, will be boosted into the upper 60's this afternoon.  A brand new cold front will sweep across the area on Thursday.  Only light scattered showers are expected, but the wind will pick up from the northwest at 15 to 25 mph in the afternoon with gusts to 40 mph.  An intense surface low spin up over Lake Superior and  move east across Lake Huron. With a strong pressure gradient, it will remain windy through Friday. Chilly high pressure from Canada will follow in behind the system. On Friday night high pressure will ridge from the center of the high on the northwest shore of Lake Superior southward along the Mississippi River.  Skies will be clear.  The wind will die off, and temperatures will drop to the mid to upper 30's with a chance of frost.  High temperatures on Saturday will only be in the upper 50's, and with high pressure centered right over the Stateline on Saturday night it will be clear, and cold again.   With sunny skies on Sunday, and a light southerly wind developing, temperatures will recover to the middle 60's by mid afternoon.  You can expect more sunshine on Monday, and very pleasant conditions with 72 degrees expected by 3 pm.
