MD Weather: Days Of Rain, Storms Stretch Into Weekend Forecast

MARYLAND — An unsettled weather pattern with rain showers and scattered thunderstorms moves into Maryland Wednesday and lingers until early next week, forecasters said. A hazardous weather outlook was issued Wednesday for much of the Baltimore-Washington, D.C., region by the National Weather Service.

The period of rain could bring more than two inches of rain in parts of Maryland by late Thursday, forecasters said. The most likely days to see rainfall will be Thursday and Friday, but showers and storms remain in the forecast through the beginning of next week.

The hazardous outlook includes the District of Columbia, Cecil, Baltimore, Prince George's, Anne Arundel, Charles, St. Marys, Calvert, Montgomery, Howard and Harford counties. It is for the Maryland portion of the Chesapeake Bay, Tidal Potomac River, and I-95 corridor through central Maryland, northern Virginia, and District of Columbia.

"Unsettled weather is expected over the next several days. Cooler than normal temps are expected through Thursday with more typical summertime temps and higher thunderstorm chances Friday and Saturday," said the National Weather Service office for Baltimore-Washington, D.C.

Temperatures will reach only the low to mid 70s Wednesday and Thursday, before heat and humidity ramps up and highs climb into the mid- to upper-80s Friday through Sunday, added the NWS.

Expect showers mainly after 5 p.m. Wednesday through Thursday night, when storms are likely. New precipitation amounts between a half and an inch of rain are possible through the evening.

Thursday brings a risk of thunderstorms also possible after 2 p.m. The NWS said new rainfall amounts between a half and three quarters of an inch possible.

The weather pattern on Friday and into the weekend looks more likely for storms, said forecasters. Showers and thunderstorms will be enhanced with daytime heating, “particularly if there is any sunshine.”

Poor beach weather is expected to develop this week from southern Georgia up through Long Island due to the building surf, added AccuWeather. As the breeze from the Atlantic continues, more moisture will be added to the air, boosting humidity levels as clouds increase.

In much of the mid-Atlantic, areas of rain will break out, expand northward and mitigate temperatures even further, AccuWeather Senior Meteorologist Dave Dombek said. In portions of the Delmarva Peninsula and the Carolinas, minor coastal flooding at times of high tide along with minor beach erosion could occur.
