Currently, a very potent s/w/vort max is moving eastward through Southern NJ, while its associated surface low, 1006mb is currently in NW Virginia. What has caused some showers and a few thunderstorms to break out is the combination of some lift, some instability, and cold air aloft in the mid levels, from 500mb to 700mb. As these showers translate eastward, they will weaken as they encounter the marine layer to the east.
Onto to tomorrow. There could be some breaks of sunshine early in the day, but that will be short-lived as a cold front crosses the area, bringing an increase in clouds. Not expecting much precip with the front, as there isn't a lot of moisture to work with. Cooler, drier air will follow behind the frontal passage tomorrow night with NW flow. Temperatures look to be in the 60's most areas, with a few 70 degree readings scattered about to the southwest.
