Baltimore, Maryland – Above-average temperatures and a more humid weather pattern are expected across Maryland from August 5–9, bringing recurring chances for showers and thunderstorms as summer warmth continues to build. While many hours will remain dry, passing storms could produce locally heavy rainfall and brief travel disruptions across the state.
According to the Climate Prediction Center’s 6–10 Day Outlook issued July 30, Maryland is favored to experience above-normal temperatures and above-normal precipitation throughout the outlook period. The climate signal points toward a warm, moisture-rich pattern with several opportunities for showers and thunderstorms from the mountains to the Chesapeake Bay.
Baltimore and Hagerstown are expected to see temperatures climb above early August averages, while communities including Annapolis, Frederick, Cumberland, Salisbury, Ocean City, and Waldorf could experience scattered afternoon and evening thunderstorms. Some storms may produce heavy downpours, frequent lightning, gusty winds, and localized flooding in low-lying or poor drainage areas. Drivers should be prepared for reduced visibility and ponding on major roadways, including Interstate 95, Interstate 70, Interstate 68, Interstate 83, U.S. Route 50, and the Capital Beltway during heavier rainfall.
The combination of warmer temperatures and elevated humidity will make conditions feel increasingly uncomfortable, especially across central Maryland and the Baltimore-Washington corridor. Residents planning trips to the Chesapeake Bay, Deep Creek Lake, Ocean City, or outdoor events should monitor local forecasts and be prepared to seek shelter if thunderstorms develop.
The overall pattern favors continued above-average warmth through August 9, with periodic showers and thunderstorms expected across Maryland. Additional outlooks from the National Weather Service will provide greater detail on the timing and coverage of individual rain events as the period approaches.
