Scattered storms could soak parts of DC region Friday

A dreary Friday could be capped off by storms and showers in parts of the D.C. region.

7News First Alert Meteorologist Eileen Whelan said that increasing clouds throughout the day will lead to scattered showers and thunderstorms developing during the afternoon and evening.

“Coverage should be greatest south and west of the I-95 corridor, particularly along and south of I-66 and US-50,” Whelan said.

There’s a “marginal risk” for severe weather mainly south and west of the D.C. area.

“Any stronger storms could produce damaging wind gusts, frequent lightning and locally heavy rain capable of isolated flash flooding. It will not be a washout, but storm chances increase during peak heating,” she said.

Highs on Friday will be in the low to mid 80s. Showers and thunderstorms may continue into the evening with storms diminishing overnight with lows ranging from 68 to 73.

Looking ahead to the weekend, Sunday could bring strong thunderstorms to the D.C. area.

Forecast

贵搁滨顿础驰听
Mostly cloudy
Chance for showers, storms
Temperatures: 78-85
Winds: Northeast 5-10 mph
A few showers and isolated thunderstorms will remain possible Friday evening, especially south and west of the immediate metro, as the remnants of an upstream weather maker move through. Most activity should gradually fade with time, leaving a mix of clouds and some breaks. Temperatures will fall from near 80 into the mid 70s by the late evening. Winds will be light, generally from the north and northeast.

FRIDAY NIGHT
Lingering showers/storms
Lows: 68-73
Winds: Light
Any leftover shower should quickly fade, with mainly dry conditions expected through the overnight hours. It will remain rather muggy with lows settling into the low 70s around D.C. and the nearby suburbs. Winds will stay light from the north to northeast, with some clouds lingering into early Saturday morning.

SATURDAY
Partly cloudy
Highs: 85-88
Winds: Southeast 3-8 mph
A fairly typical August day with a mix of clouds and sunshine, temperatures climbing into the upper 80s and humidity remaining slightly noticeable. Most of the DMV should stay dry, with the better chance for an afternoon or evening thunderstorm focused well to the west and southwest, mainly toward Pendleton and Grant counties in West Virginia and west-central Virginia. Any severe weather threat will also be confined mainly to those areas. Winds will gradually turn from the east to southeast.

SATURDAY NIGHT
Mostly cloudy
Lows: 70s
Winds: Light
Mostly cloudy, warm and muggy with temperatures slowly settling into the low 70s. Most of the evening should stay dry, although the chance for a few showers begins to increase late at night and toward daybreak Sunday. Winds remain light from the south, helping keep plenty of humidity in place.

SUNDAY
Partly sunny
PM Rain, Storm chance
Highs: 87-92
Winds: South 5-10 mph
This is the day to watch. It will turn warmer and increasingly humid, with highs in the mid-to-upper 80s to lower 90s and feels-like temperatures climbing into the 90s. An approaching front will help trigger scattered showers and thunderstorms, with the better chance for stronger storms developing during the afternoon and evening. Damaging wind gusts are the primary severe weather concern, while the high humidity could also support torrential rain and localized flash flooding. As of this writing, the Storm Prediction Center has the entire viewing area in a Level 1 of 5 ‘marginal’ risk for severe storms, while the 黑料不打烊 Prediction Center has highlighted the region in level 2 of 4 ‘slight’ risk for flash flooding. A tornado or two cannot be ruled out given the amount of wind shear in the atmosphere. If current trends continue, our team may go on weather alert, so stay with us as we continue to refine the timing and threats.

MONDAY
Partly sunny
Showers and storms
Highs: near 90
Winds: Northwest 5-10 mph
Very warm and humid conditions continue, with highs around 90 and heat index values potentially reaching the upper 90s during the afternoon. Another round of scattered showers and thunderstorms will be possible as a cold front moves through the region. Exactly how active Monday becomes will depend on the timing of the front, but southern Maryland and central Virginia could still have a stronger storm threat if Sunday鈥檚 system is slower to move east. Storm chances should begin winding down behind the front later Monday or Monday night.

TUESDAY
Mostly sunny
Highs: around 85
Winds: Northwest 5-10 mph
A noticeable change arrives behind the front. Temperatures will still reach the mid to upper 80s, but much drier air will filter in from the north, with dew points dropping into the 60s and eventually the 50s in parts of the region. Sunshine should become more prevalent, and with the lower humidity and little or no thunderstorm activity expected, Tuesday looks considerably more comfortable.
