The trough of low pressure will begin to weaken tomorrow, but will still provide a focus for showers and thunderstorms. Highs tomorrow will again be near 80 degrees.
Friday will be a transition day, as the trough weakens and is pushed out by an area of high pressure. Isolated showers and thunderstorms will still be possible, but will not be as widespread as they have been. Highs will begin to creep upwards, reaching the mid 80s.
High pressure takes control for the weekend, bringing a return of sunshine. Southerly flow around the high will also raise temperatures and dew points. Highs Saturday will approach 90 degrees, and will push into the 90s Sunday and Monday. The warm and moist air will also allow for an isolated shower or thunderstorm to develop each afternoon. This weekend will feel much like a typical late July or August weekend here in the Mid-Atlantic region.
High pressure remains in control into early next week, before a cold front approaches from the north towards mid week.
