A big change in air masses takes hold today as much cooler air comes in on the backside of that departing massive storm system.  While there could still be some lingering morning showers, high pressure builds in from the North through the day.  That should lead to rapidly drying conditions with decreasing clouds.  The difference in pressure between the departing low and the arriving high will lead to very strong winds.  Those brisk breezes out of the North-Northeast off Lake Michigan's shores could gust as high as 35 miles per hour and keep temperatures in the low to mid 50s.  Clear skies continue into tonight and with winds decreasing there could be some patchy frost inland as temperatures drop into the 30s.  We'll finish the work and school week with sunshine for Friday.  The mainly dry conditions with a mix of sun and clouds continue through the Memorial Day holiday weekend, as will the cool readings in the low 60s.
