Dwindling Wednesday rain chances

Today - Wednesday - will be mostly sunny with afternoon temperatures topping out near the 80º mark. Just before today's sunset at 8:13 p.m. clouds will roll in thanks to an approaching cold front. Forecast rain totals from this boundary have now dissipated to less than a tenth of a inch, lending truth to an old weather saying that "Drought begets drought". 

The cold front is associated with a low pressure center which is traversing the Great Lakes region. Mature storm systems like this one produce a "comma-head" signature on satellite views as denoted on this image:

The cold front itself is just beginning to cross the Appalachian Mountains this morning.

Cooler air filtering in via northwest winds will hold Thursday's maximum temperatures to the low 70s. Skies will be mostly sunny tomorrow morning before clouds build overhead during the early afternoon hours. Those clouds will evaporate tomorrow night, and local thermometers will drop back into the mid-40s by dawn Friday.

Then the heat arrives for the weekend. Get those fans and air conditioners ready for the 90s to show back up by Sunday!!
