The National Weather Service has issued a Flood Watch for Washington, D.C., and parts of Northern Virginia until 2 p.m. Sunday, warning that flash flooding and localized heavy showers or thunderstorms are possible as wet weather moves in.
By midmorning Sunday, the warning is already out—damp skies over Washington, D.C., and Northern Virginia come with a clock attached. The National Weather Service issued a Flood Watch until 2 p.m., saying flash flooding caused by excessive rainfall is possible across the region.
The risk is not limited to the city. The watch covers parts of Northern Virginia, including Arlington, Falls Church, Alexandria and Fairfax.
Officials warned that heavy downpours could overwhelm drainage. Storm drains and ditches may become clogged with debris, leading to flooding.
The Weather Service described the trigger in plain terms: a disturbance riding along a stalled front is expected to bring localized heavy showers and perhaps a thunderstorm.
A First Alert Meteorologist. Mark Peña. said the storms won’t linger all day. but they could pack a punch when they arrive. “A few storms could produce briefly heavy rain. lightning and gusty winds. ” Peña said. adding that most activity should fade toward sunset. followed by clearing skies overnight.
For people trying to move through Sunday plans with minimal disruption, the forecast offers only partial comfort. Clearing overnight sets the stage for a calmer start to the workweek. Peña said high pressure builds Monday, bringing more sunshine, lower humidity and very low rain chances. Temperatures, he added, will stay seasonable—conditions framed as favorable for outdoor plans.
But the wet weather isn’t the only thing the region is tracking. Heat and humidity rise again Tuesday as winds turn southerly, with highs returning to the lower 90s under mostly sunny skies.
By Wednesday, officials expect dangerous heat to build and continue into the Fourth of July holiday weekend. Highs are forecast in the upper 90s, with the possibility they could approach 100. Heat index values are expected to land between 102 and 107.
The forecast sequence is stark: a Flood Watch until Sunday afternoon, a sunshine-driven reprieve Monday, and then a steady climb toward dangerous heat beginning Tuesday and peaking during the holiday stretch.
Sunday’s outlook calls for scattered showers and storms, with highs between 80 and 85. Winds are forecast at northwest 5-10 mph.
Monday should be mostly sunny, with highs between 85 and 90 and southeast winds of 5-10 mph.
Tuesday remains mostly sunny, with highs between 88 and 93 and south winds of 5-10 mph.
Wednesday is forecast to be sunny and hot, with highs between 95 and 100 and a heat index between 102 and 107. Winds are expected to be southwest 5-10 mph.

Flood watch again? DC can’t catch a break.
So it says until 2 p.m. but like… are we talking actual flooding or just “watch” vibes? I feel like storm drains always “may clog” every time and then nothing happens.
I read this as the flood watch is only for DC, not NoVA, but then it keeps naming Arlington and Alexandria so idk lol. Also storms “could pack a punch” like how heavy are we talking, because my car already has enough water spots.
Let me get this straight: flash flooding possible Sunday, then Monday is sunny, then Tuesday it’s back to lower 90s, then Wednesday is like dangerous heat and heat index 102-107. Great, so we’re basically doing weather roulette. People act like heat is worse but I’ve seen people slip on slick sidewalks from rain too, so both are a problem.
