WASHINGTON DC METRO AREA FORECAST DISCUSSION
Raised precipitation chances across the Shenandoah Valley into the central Virginia piedmont and southern Maryland through late this morning with an ongoing batch of showers. Otherwise, the forecast remains largely on track. Will be monitoring heavy rain potential with any storms that develop where breaks of sun occur which may actually focus in the I-70 corridor later today.
