If you’re stepping out in Washington, D.C. on Tuesday without checking the skies—you might regret it. A calm, humid morning will give way to a sudden atmospheric switch-up: powerful afternoon thunderstorms, backed by building heat and moisture, are expected to hit the capital just in time to disrupt commutes, events, and outdoor plans. As the day heats up, so does the risk—and by Wednesday, the heat will reach a sweltering 92°F.
This is more than a passing shower. It’s a weather combo that could leave roads flooded, skies flashing, and summer plans soaked before they even begin.
Tuesday’s Forecast: The Setup for a Stormy Surprise
Tuesday starts quietly enough—overcast skies, humid air, and temperatures rising into the low 80s by midday. But all that trapped heat and moisture sets the stage for strong thunderstorms by late afternoon, some of which could deliver:
-
Torrential rain in short bursts
-
Sudden, gusty winds
-
Cloud-to-ground lightning
-
Small hail and brief street flooding
The worst of it is expected between 2 p.m. and 7 p.m., just when many people are heading out of offices or making school pickups. Roads could become slick quickly, and low-lying areas may struggle to drain if multiple storm cells pass through.
The Heat Builds Through Midweek
While Tuesday’s storms pose the most immediate threat, the heat really takes hold starting Wednesday, when highs are expected to soar into the upper 80s, with “feels like” temperatures climbing into the low 90s due to rising humidity.
That sticky, heavy atmosphere won’t just be uncomfortable—it’s also perfect fuel for more afternoon thunderstorms, especially during the late commute hours again. You’ll want to pace outdoor activities, drink extra water, and keep an eye on fast-changing radar patterns.
By Thursday, the forecast stays similar: hot, humid, and unsettled. Another round of afternoon storms could pop up, particularly near bodies of water or open pavement.
Relief Arrives Just in Time for the Weekend
By Friday, D.C. residents will finally get a break. Sunny skies and lower humidity return, with highs still in the upper 80s—but the air will feel lighter, and chances of rain drop off dramatically. The weekend ahead looks bright and classic-summer, with temperatures staying warm but dry through Saturday and Sunday.
Perfect weather for poolside lounging, rooftop dinners, and all the Juneteenth celebrations planned across the region—as long as you make it through the stormy stretch first.
Quick Tips to Stay Safe and Ready
