Discussion
High pressure will maintain control of the weather here today and tonight, but then strong low pressure will ride up along or near the east coast and produce significant rainfall in the Mid-Atlantic region from later tomorrow into late Saturday. A second wave of energy will rotate through a deep trough in the upper atmosphere late in the weekend and keep it unsettled and chilly around here with additional showers likely from Sunday night into Monday. Dry and chilly weather should return for Tuesday and Halloween Day (Wednesday).
