Cloudy skies over Washington this morning will give way to a hotter, more humid Sunday, with temperatures climbing from around 73 degrees to a high near 90. Isolated showers and thunderstorms could develop after 2 p.m., giving outdoor plans a small but real chance of a sudden interruption. The rest of the day should stay mostly dry.
The National Weather Service puts Sunday’s rain chance at 20%, with south winds between 3 and 9 mph and new rainfall generally below a tenth of an inch. Any storms should fade quickly around sunset, but the combination of heat and humidity will make the afternoon feel more uncomfortable than the thermometer alone suggests.
The Heat Ramps Up Fast
Monday is forecast to reach 94 degrees, followed by highs near 98 on both Tuesday and Wednesday. Overnight temperatures will offer limited relief, staying in the mid-to-upper 70s through much of the stretch.
The forecast discussion warns that heat index values could approach Heat Advisory criteria, depending on humidity and cloud cover, although no land-based advisories are currently listed for the District. In practical terms, Tuesday and Wednesday look like the days to limit long stretches of midday sun and keep water close.
Storm Chances Grow Later In The Week
Monday brings another chance for isolated afternoon storms, while Tuesday has a slight chance and Wednesday is expected to be mostly sunny. Rain and thunderstorm chances increase to 40% Thursday and Friday before temperatures ease to a still-warm 86 degrees Saturday.
Thursday could reach 96 degrees before storms become more likely after 2 p.m., while Friday is forecast to top out near 90 with showers and thunderstorms possible. Timing remains uncertain several days out, so commuters and anyone planning outdoor events should keep an eye on the forecast as the week develops.
Plan For The Hot Hours
The District’s heat information page includes safety guidance and cooling-center information. For the hottest afternoons, schedule strenuous activities earlier or later in the day, take breaks in shade or air conditioning, drink plenty of water and check on older neighbors or anyone more vulnerable to heat.
