Washington woke up sticky on Thursday, July 16, with a milky haze hanging over the city and temperatures already in the low 80s at Reagan National. A Code Orange air-quality alert and drifting Canadian wildfire smoke will keep the sky hazy while highs climb to near 98°F and heat-index values top out around 103.
Afternoon Heat And Hazy Skies
The National Weather Service is calling for a high near 98°F on Thursday and flags areas of smoke between about 7 a.m. and 3 p.m., with generally light northwest winds, according to the National Weather Service. Forecasters note that smoke higher up in the atmosphere is limiting mixing, which has made decisions about issuing heat headlines more complicated even as it still feels decidedly uncomfortable outside.
Air Quality And Who Should Take Care
The NWS alert reports that the Metropolitan Washington Council of Governments and the District Department of Environment have issued a Code Orange, which means air may be unhealthy for sensitive groups. Children, older adults, and people with asthma or heart and lung disease are urged to limit prolonged outdoor exertion and keep quick access to medications. The haze is tied to a southward plume of Canadian wildfire smoke that could hang around into Friday, at times cutting visibility and degrading air quality.
Weekend Storm Risk
Thunderstorm chances ramp up this weekend as a front drops into the region, with Saturday, July 18, looking like the main event. The forecast shows roughly a 90 percent chance of showers and thunderstorms that day, with potential for heavy downpours and damaging gusts. That threat could spill into Sunday if the front stalls, so treat outdoor plans as tentative and be ready to duck inside quickly if storms bubble up. Short bursts of rain could help knock some of the smoke out of the air in localized spots.
Where To Find Relief And More Information
For anyone who needs a break from the heat, the District operates free cooling centers and offers extended services during heat emergencies, and you can find locations through the District of Columbia government or call 311 for transportation help. Check current air-quality forecasts from regional officials before committing to long stretches outside, drink plenty of water, and shift strenuous work to morning or evening while the midafternoon heat and haze hang on. For the latest on watches and advisories, keep an eye on the National Weather Service and updates from local agencies.
