Maryland Forecast for Saturday, August 1, 2026: Warm, Mostly Sunny and Mainly Dry
Maryland begins August with warmer temperatures, increasing humidity and predominantly dry weather.
High pressure will move offshore during the day, allowing winds to turn south or southwest. This return flow will gradually bring more moisture into the state ahead of a slow-moving weather system expected Sunday and Monday.
Most Maryland communities will remain dry Saturday. An isolated afternoon or evening shower or thunderstorm may develop, primarily across Western Maryland and areas west of the Blue Ridge.
No organized severe-weather threat is expected.
MORNING COMMUTE
Saturday morning will begin clear to partly cloudy and comfortable.
Temperatures around sunrise will range from the upper 50s in the Western Maryland mountains to the upper 60s and low 70s around Baltimore, Washington, Southern Maryland and the Eastern Shore.
Patchy fog is possible in sheltered Western Maryland valleys, but widespread fog is not expected.
Roads should remain dry with good visibility.
The primary travel issue will be increasing weekend and beach traffic along:
- US-50
- US-301
- The Chesapeake Bay Bridge

SUNDAY OUTLOOK
Sunday becomes more unsettled as a slow-moving frontal system approaches from the Ohio Valley.
Showers and thunderstorms become increasingly widespread during the afternoon and evening.
The current severe-weather risk appears limited by weak atmospheric winds and extensive cloud cover. However, any storm may produce heavy downpours and localized flooding.
SUNDAY NIGHT AND MONDAY OUTLOOK
Rain and thunderstorms may become widespread Sunday night into Monday.
Atmospheric moisture will increase significantly, creating the potential for:
- Torrential downpours
- Repeated thunderstorms
- Localized flash flooding
- Ponding on roads

- Travel disruptions
Some forecast guidance supports localized rainfall totals of two to three inches where favorable conditions align.
The exact placement and magnitude of the heaviest rain remain uncertain.

Saturday will be warm, increasingly humid and mainly dry across Maryland.
An isolated afternoon or evening storm is possible across Western Maryland, but most communities will experience favorable outdoor conditions.
The weather turns considerably more unsettled Sunday into Monday, when widespread showers, thunderstorms and locally heavy rainfall become possible.
