Today (Friday): Mostly sunny skies and fairly low humidity should rule most of the day, though clouds may increase a bit during the afternoon. Warm high temperatures make it into the upper 80s to near 90. Humidity remains low, so enjoy! Rain chances are small - only about a 10% chance of a shower or small storm - but worth the mention. Confidence: Medium-High

Tonight: We’ll see a 20% chance of a shower as breezes turn more from the east/northeast and skies turn partly to mostly cloudy. Those onshore breezes add a little moisture to the air, but overall it still feels pleasant with lows in the 60s to near 70. Confidence: Medium

Tomorrow (Saturday): Low pressure now expected to develop today along the North Carolina coast and move north tomorrow has thrown a wrench into what had looked like a mostly sunny Saturday. Now we may be looking at a partly to mostly cloudy day and even a 30% chance of showers, especially in the afternoon. Highs could be anywhere from the upper 70s to the upper 80s depending on how many clouds and showers. If the weather does hold up, try heading over to National Harbor to check out the first ever Dragon Boat Races - looks like almost anyone can participate! Confidence: Low

Tomorrow night: Shower chances stay around 30% with substantial clouds likely. Can’t rule out a localized downpour, too. Lows head down into the 60s. Confidence: Low-Medium

Sunday: Despite the threat of some clouds (partly to mostly cloudy skies) and showers (30% chance) and a bit more humidity, I still think you should try to get outdoors. Check out the opening weekend of the Maryland Renaissance Festival with, of course, enough sunscreen to keep you burn-free during the midday hours. While clouds won’t completely block the UV, they should keep highs in the 80s. Confidence: Low-Medium


A few showers are possible Sunday night, but overall chances for rain should be on the decline. We’ll update you if that changes. Pre-dawn low temperatures should be mainly in the 60s. Confidence: Low-Medium

Monday we may see mugginess back into the noticeable range. Overall the daytime looks mainly sunny with fairly warm highs in the mid-80s to around 90. Maybe a shower or thunderstorm late in the day or Monday night as a cold front approaches. Confidence: Medium

Highs on Tuesday should still be mild, in the 80s, even with some clouds and a 30% chance of showers or thundershowers with the cold front still around. And while, no, any showers wouldn’t be associated with Isaac, rest assured we are watching its ultimate direction. Confidence: Low-Medium
