Low pressure over GA and high pressure well east of the New England coast are causing a steady flow of moisture from the Atlantic Ocean west/northwestward across the region. As the low pressure continues to move northward, the rain will get heavier in spots and there could be some isolated thunderstorms. It appears the heaviest rain will fall west and southwest of the metropolitan Washington area. In fact, the National Weather Service has issued a Flood Watch for Fauquier, Culpeper and Rappahannock Counties and westward in VA. As the graphic below shows, lighter rain will fall outside of the watch area.
More rain is forecast tomorrow with isolated thunderstorms. On Thursday, temperatures will warm into the lower 70s and the upper 70s on Friday. Scattered showers will still be possible on Thursday with an isolated thunderstorm possible on Friday afternoon.
