FLOOD WATCH BEGINS AT 2PM 

TODAY:
Partly Cloudy, Sticky
Scattered PM Thunderstorms
Highs: 88-90
Heat Index: 90-95
Winds: South 5 mph
Wednesday afternoon brings a volatile weather setup as tropical moisture surges into the region, ahead of a stalled front. Expect a hot, humid day with highs in the upper 80s to lower 90s and dew points soaring into the 70s. Storms will fire up after 4 p.m., rapidly increasing in coverage between 6 and 9 p.m. These slow-moving storms could unleash torrential rain—possibly 1 to 2 inches per hour in spots. A flood watch is in effect from 2 p.m. to midnight. Urban flooding is a serious concern during the evening commute and overnight, particularly in low-lying and poorly drained areas. First Alert Weather will be on both storm and flood alert. 

OVERNIGHT:
Storms End, Lingering Showers
Lows: 70s
Winds: Southeast 3-8 mph
Any thunderstorms and pockets of moderate to heavy rain will draw to a close with lingering showers continuing into the overnight. The flood watch remains in effect through midnight, but flooding risks could extend into early Thursday morning—particularly in low-lying areas with poor drainage. Overnight temperatures will stay in the mid-70s, with little relief from the humidity.

THURSDAY:
Scattered Showers, Storms
Highs: 80-85
Winds: South 5-10 mph
A little less heat, but more in the way of clouds and showers. Highs will top out in the lower to middle 80s, however, the stickiness factor continues in typical D.C. summertime fashion. Scattered to widespread storms are likely again in the afternoon, and slow-moving cells may drop a quick 1/2 to 1-inch of rain. Localized flooding may become problematic, especially areas that have had significant rainfall totals this week. 

FRIDAY:
Scattered Showers, Thunder
Highs: around 85
Winds: Northeast 3-8 mph
Storm chances dip just a little, but still looking at more humidity, more clouds, and more late-day storms. Highs are back in the upper 80s, and any storm could once again bring pockets of moderate to heavy rain, gusty winds, and lightning. It’s not quite a copy-paste of earlier in the week, but close. The forecast trend is a little drier as we move into the weekend.

SATURDAY:
Partly Cloudy, PM Storms
Highs: near 90
Winds: South 5-10 mph
Expect partly cloudy skies and the potential for scattered thunderstorms Saturday afternoon and evening. The coverage of storms will be a bit more hit-or-miss, but the atmosphere remains moisture-rich, so any storm will be capable of brief heavy rain. Highs will climb into the lower 90s, with heat indices in the upper 90s during the midday hours before clouds and storms develop.
