Clear early-morning skies and a mild 72°F at Reagan National are quickly giving way to a full-on heat blast in the District. By mid-afternoon, highs are set to rocket into the upper 90s across much of the city, with a few neighborhoods flirting with 98°F. It will rank as one of the hottest days of the year so far, and the heat does not back off much overnight, with lows only slipping into the low 70s. The harshest hours will be roughly 3 to 5 p.m., so that is the window to avoid for running, yard work, or any other heavy outdoor effort.
Afternoon Heat And Records
The National Weather Service is calling for highs near 98°F along the I‑95 corridor and through the urban core, several degrees above what is typical in May and likely to push daily records at Reagan National. A southwesterly breeze around 5 to 10 mph, with gusts that could reach 15 to 20 mph in the afternoon, will offer only modest relief, so shade will be your best friend.
Storm Threat Wednesday
A strong cold front is on track to arrive Wednesday afternoon into Wednesday evening, bringing a widespread shot at showers and thunderstorms. Some of those storms could turn strong, with the potential for damaging wind gusts and hail. Once the front moves through, temperatures tumble, with a sharp 20–30°F cooldown expected from Thursday into Friday.
What To Know Today
Heat safety is the headline. Drink plenty of water, scale back strenuous outdoor work during the late-day peak, and check in on older neighbors and anyone living without air conditioning. The District has a Heat Alert in effect, and the mayor’s office has information on cooling centers and shelter options, according to the Mayor's office. For help, you can call 311 or the Shelter Hotline at (202) 399‑7093.
Boating, Commute And Outdoor Plans
Southerly gusts this afternoon may kick up choppy conditions on the Potomac and nearby tidal waters, and small‑craft advisories are possible in parts of the bay. If you have outdoor events or practices scheduled for midweek, factor in a weather backup for Wednesday evening when thunderstorms could force delays or cancellations.
