Residents in the D.C. area should prepare for a soggy suite of days ahead as the National Weather Service warns of potential flooding due to persistent showers and thunderstorms. The latest update indicates a high chance of precipitation, with today's chance towering at 70%, and the likelihood of rain remaining significant through Thursday. The combination of Southeast winds and heavy rain might lead to some urban and localized flooding, particularly during this afternoon's forecasted thunderstorms.
For tonight, Washingtonians are looking at continued rainfall, with a 70% probability of showers and potential thunderstorms before the break of dawn tomorrow. Predicted rainfall volume hovers between a quarter and half an inch, though higher volumes are possible where thunderstorms occur. Today's high, hovering near 85°F, will give way to lows around 73°F in the evening, providing little reprieve from the muggy conditions the city has endured since sunrise.
Moving in tomorrow, the weather seems unwilling to let up. While we start with only a slight chance of showers, thunderstorms may roll in by midday with temperatures predicted to near the 90-degree mark. Each day through Wednesday follows a similar pattern: the odd chance of rain in the mornings, escalating into a likelihood of storms and showers by the afternoons. Heavy rainfall, as predicted by the National Weather Service, could lead to circumstances where flash flooding becomes a concern, particularly in the more densely populated and paved regions of the metro areas.
Those living or commuting within the I-95 corridor should remain vigilant and keep an eye out for updates, as the pattern of storms this week has the power not only to dampen spirits, but also swell waterways and overwhelm drains. The Hazardous Weather Outlook issued early this day highlights this risk, even as spotter activation isn't anticipated at this point. By the time we reach the weekend, the region can expect a switch to drier conditions with more sun in store, and temperatures approaching the 90s—though not without enduring several tumultuous days first.
