THURSDAY EVENING:
Partly cloudy. Isolated PM storms
Temperatures: 90s to 80s
Winds: Southwest 5-15 mph
The National Weather Service has issued a heat advisory for D.C. until 8 p.m. Feels like temperatures will hold in the 90s through the evening. A pop-up storm could bring a quick downpour and gusty winds, although latest forecast trends show limited chances.
THURSDAY NIGHT:
Scattered clouds
Lows: 70s
Winds: Northwest 5 mph
It will remain warm and very humid overnight with just a few passing clouds overhead. Temperatures are set to hold in the 70s with a bit of haze by early morning.
FRIDAY:
Partly sunny. Chance showers, storms
Highs: 83-86
Winds: Northwest 5-10 mph
Thursday’s extreme heat will ease, although quite warm, with afternoon highs around in the upper 80s. Expect a mix of clouds and sun throughout the day, as a cold front advances across the DMV. The front may trigger scattered thunderstorms, especially west of the I95 corridor. Some storms could be strong to severe, capable of producing gusty winds, frequent lightning and localized flash flooding.
SATURDAY:
Scattered PM showers and storms
Highs: 83-88
Winds: South 8-12 mph
The atmosphere remains unsettled as the frontal boundary stalls over the Mid-Atlantic, keeping cloud cover in place and the chance for isolated to scattered thunderstorms. Temperatures will be seasonably warm, with highs in the middle to upper 80s, the stickiness factor a bit higher. The most likely time for storms will again be in the afternoon and early evening. Any storm that develops may be slow-moving and could still dump heavy rain in a short amount of time, leading to localized flooding, especially in typical trouble spots. Some storms will also have the potential to become strong to severe.
SUNDAY:
PM showers and storms
Highs: near 90
Winds: West 5-10 mph
The heat makes a comeback to close out the weekend, with afternoon highs soaring to the lower 90s, and humidity levels surging with heat index values closer to 100. Skies will be partly to mostly cloudy, with scattered showers and thunderstorms, primarily during the second half of the day. These storms may be briefly intense, producing heavy rainfall, gusty winds and frequent lightning.
