Low pressure finally moves closer today and with it come periods of showers and a few embedded thunderstorms. While previous rounds of rain this week were more hit and miss, these drops should give our lawns and gardens a pretty good soaking with half an inch to an inch of water through tonight.  As the storm system pulls away, we'll see some lingering showers into Thursday morning, but high pressure building in should lead rapidly to drier air and clearing by the afternoon.  That sets up a sunny Friday to finish the work week.  Winds have shifted from the Southwest to a more Northeasterly flow off of Lake Michigan ushering in much cooler temperatures.  In fact, as the chillier air settles in to the region, reading could fall all the way into the 30s Thursday night into Friday morning.  While there's no concensus among the computer models through the Memorial Day Weekend, at this point the trend appears to be mainly dry with some sunshine and slightly below average temperatures in the low to mid 60s.
