What's next? Seasonable heat, high humidity and storm chances continue through Tuesday, when an approaching front could generate more widespread late-day storms. Trending drier later in the week.
🔷 CWG's detailed D.C.-area forecast
Today's daily digit — 6/10: A bit steamy with late-day thunderstorms possible. It is late June after all, but the humidity is a bit much. | 🤚 Your call?
The digit is a somewhat subjective rating of the day's weather, on a 0-to-10 scale.
Forecast in detail
Today (Sunday): Areas of patchy fog are possible early morning, then turning mostly sunny and steamy with afternoon highs in the upper 80s to low 90s. Some spots should see the heat index reach the upper 90s to near 100 with the high humidity. A few hit-or-miss showers and thunderstorms are possible after 2 p.m. or so. Confidence: Medium-High
Tonight: Showers and thunderstorms, a few capable of damaging winds and flooding, could be scattered about during the evening. A few showers and a storm could linger overnight. Otherwise partly cloudy overnight with lows in the low to mid-70s. Confidence: Medium-High
Tomorrow (Monday): Not much of a change to start the workweek with times of sun and clouds, highs in the upper 80s to low 90s, and a few strong to severe afternoon thunderstorms possible. Once again, some spots may see the heat index top out in the upper 90s to near 100. Confidence: Medium-High
Tomorrow night: A couple of showers and storms remain possible during the evening. Partly cloudy overnight with lows in the 70s. Confidence: Medium
A look ahead
An approaching front on Tuesday increases the chance for more numerous showers and thunderstorms by the afternoon into evening. Highs once again reach the upper 80s to low 90s under partly to mostly sunny skies, followed by Tuesday night lows in the upper 60s to low 70s. Confidence: Low-Medium
Wednesday may trend a couple of degrees cooler, but we should still manage the mid-80s to near 90. Drier air starts to arrive, although a shower chance can't be totally ruled out. Wednesday night lows dip to the upper 60s to low 70s again.
The early outlook for Thursday and July Fourth Friday is partly to mostly sunny, somewhat less humid, and a pretty low chance of rain as of now. Thursday highs aim for the upper 80s to near 90, then mid- to upper 80s on the Fourth. Confidence: Medium
