11:15 AM | *Unsettled weather for the Mid-Atlantic region from later today through tomorrow night to include the chance of some heavy rain and strong thunderstorms…an early tropical threat* — Arcfield Weather

Unsettled conditions in the Mid-Atlantic

The boundary zone associated with the back door cool front still exists today in the Mid-Atlantic region and it will contribute to some instability later in the day and tonight.  As a result, the threat for showers and thunderstorms will increase later in the day and tonight; primarily, in areas to the north of the PA/MD border. In fact, the highest chance for strong-to-severe thunderstorm activity during this time will be in New York City and scattered strong storms can reach all the way down into the Philly metro region late today or tonight.

On Thursday, the highest threat for strong-to-severe thunderstorm activity will shift a bit to the south and will include the DC metro region.  Low pressure will develop on Thursday along an incoming frontal boundary zone and this will enhance chances for rain in the Mid-Atlantic region; especially, to the south of the PA/MD border and some of the rain can be heavy.  High pressure will resume control of the weather in the region at the end of the week and the weekend is shaping up to be quite nice with comfortably warm conditions likely on Saturday, Sunday and Monday.
