Today (Sunday): Even though Alberto is well south, its associated onshore flow means increasing afternoon clouds after a mostly sunny morning, and the chance of a few afternoon showers mainly across Southern Maryland. But overall, for most of us it’s a warm and pleasant day with highs near 80 to the low 80s, except for mid-70s along the Chesapeake Bay and in Southern Maryland. Breezes come from the northeast around 10-15 mph. Confidence: Medium-High

Tonight: The center of Alberto edges closer to the South Carolina coast, and the onshore flow to its north keeps us on the humid side. That spells cloudy skies and a 50% chance for some light showers. The clouds and increasingly moist air lead to mild overnight lows in the low-to-mid 60s. Confidence: Medium

Tomorrow (Monday): Alberto doesn’t appear to be a direct threat for the D.C. area. But we feel its effects in the form of a 60% chance of showers, and the possibility of afternoon thunderstorms that could produce locally heavy rain. Amidst mostly cloudy skies, it’s a warm and somewhat humid day with highs in the 70s. Confidence: Medium

Tomorrow night: Unsettled conditions stick around with mostly cloudy skies and a 50% chance for showers. With the tropical influence, we’re mild and a bit muggy once again with lows in the low-to-mid 60s. Confidence: Medium


What remains of Alberto combines with an approaching cold front to give us a decent (60%) chance for showers and afternoon thunderstorms on Tuesday. We’ll again have mostly cloudy skies and some humidity as highs top out in the 70s. Shower chances should diminish Tuesday night, but probably don’t die out completely as lows dip to the low-to-mid 60s. Confidence: Low-Medium

For Wednesday, expect the unsettled pattern to continue with a stalled front giving us a 40% chance of showers and thunderstorms. Partly to mostly cloudy skies may yield enough sun to warm highs to the upper 70s to near 80. Confidence: Low-Medium
