Harrisburg, Pa. – Dry weather will dominate the Mid-Atlantic region through Thursday, with streamflows continuing near or below normal and little to no rainfall expected in most basins.
According to the National Weather Service Middle Atlantic River Forecast Center, high pressure is keeping widespread precipitation at bay. The only exception could be the upper Susquehanna basin, where a weak disturbance might trigger light showers by Thursday afternoon.
Across Pennsylvania, Maryland, Delaware, Virginia, and parts of West Virginia, stream gauges show below-average flows, especially in the lower Susquehanna, Potomac, and upper James River basins. The USGS map indicates widespread low to very low streamflow levels, signaling reduced groundwater recharge and minor river or creek fluctuations.
With 7-day precipitation totals running up to 2 inches below average in some areas, residents relying on wells or irrigation should monitor conditions. While no major flooding or drought emergencies are expected, the prolonged dry period could stress local ecosystems if it persists into next week.
The current pattern is expected to hold until Thursday evening, with the next update likely if precipitation develops in northeastern Pennsylvania. No flood watches or advisories are in effect at this time.
