Storm Team4 of NBC4 Washington reported that Thursday, September 10, 2026, will be largely dry across the Washington, D.C. area, with temperatures climbing to the high‑90°F range. The forecast calls for a peak temperature close to 90°F and only a brief chance of rain developing after dark.
The rise in temperature is linked to a return of humid air that is moving into the region. This moisture increase is expected to lift daytime heat while also setting the stage for the possibility of precipitation during the late‑night hours. The forecast therefore highlights a contrast between a hot, dry daytime and a modest chance of rain as the evening progresses.
Looking beyond Thursday, the local outlook shows scattered showers becoming more common over the weekend. The pattern suggests that while Thursday will stay mostly dry, the following days will feature intermittent rain as the humid air continues to influence the area. By early next week, forecasters anticipate a shift in the larger weather pattern that could alter the rain chances.
Overall, residents can expect four days of rain chances beginning with Thursday night and extending through the weekend. The combination of near‑90° heat and late‑night precipitation potential underscores the impact of the returning humid air mass on the short‑term weather in Washington, D.C. Those planning outdoor activities should be prepared for high temperatures during the day and keep an eye on evening forecasts for the possibility of rain.
