A strong cold front will advance on the region tomorrow afternoon and night; dividing 50's from 20's. A wave of low pressure will move along the front through the central plains into the Mid Atlantic region Thursday night. As colder air plunges south, moisture will be transported north. This will set the stage for rain changing to snow late Thursday night into early Friday morning before drier air moves in. QPF amounts will generally be around .5", but a decent portion will fall as rain. This still leaves us with the potential for one to two inches of wet sloppy snow by Friday morning, primarily in the higher elevations. If colder air works south quicker, it may be more, and so there is a slight chance of a delay on Friday.
