After several days of highs in the low to mid-90s, a cold front will bring a noticeable cool-down to our region. Showers and storms this evening will give way to cloudy skies and much cooler temperatures to start the week.
Highs will stay in the 70s to low 80s Monday and Tuesday, with some drizzle or light showers possible before drier weather returns midweek. By next weekend, warmer and more humid air will move back in, along with the chance for thunderstorms.
Hot, muggy weather continues Thursday, with another round of dangerous heat and the potential for flash flooding. Temperatures will reach the upper 80s to low 90s, but high humidity will make it feel more like 95–105 degrees. Scattered showers and thunderstorms are expected to develop by early afternoon, producing torrential downpours that could lead to significant flooding—especially in and around the I-66/US-50 corridor.
The National Weather Service has issued a Flood Watch from Thursday afternoon through late Thursday night for a wide area including the District of Columbia, most of central and southern Maryland, and northern Virginia. Some areas could see multiple rounds of storms with rainfall totals between 4 to 6 inches, causing extensive street flooding and flash flooding in poor drainage areas. Residents are urged to avoid travel during the evening commute and never drive through flooded roads.
A stretch of dangerous heat will grip the region Wednesday before strong storms move in on Thursday and usher in cooler weather for the weekend.
The National Weather Service has issued a Heat Advisory from 11 a.m. to 8 p.m. Wednesday for much of the D.C. metro area, including northern and central Virginia and parts of Maryland. Heat index values are expected to reach between 105 and 109 degrees, making it potentially hazardous for those spending extended time outdoors. Residents are urged to stay hydrated, remain in air-conditioned spaces when possible, and check on vulnerable neighbors and relatives.
After a sweltering weekend that brought heat index values over 100 and a heat advisory, today feels like a slight relief. Highs will reach the low 90s, but lower humidity and fewer storms will make conditions feel more manageable. Looking ahead, hot and humid weather returns through midweek, with highs climbing into the mid to upper 90s by Wednesday. However, a strong cold front arrives late in the week, bringing the chance for showers and storms—followed by a significant drop in temperatures heading into the weekend.
Weather Highlights
A heat advisory is in effect across the region today, with heat index values expected to climb as high as 107 degrees, according to the National Weather Service.
The advisory runs from noon to 8 p.m. Sunday and covers much of northern and central Virginia, including Prince William County, Manassas, Manassas Park, Stafford County, and the City of Fredericksburg. It also includes the D.C. area and parts of southern Maryland.
MANASSAS, Va. – A heat advisory is in effect across Northern Virginia and the D.C. region today, with the National Weather Service warning that it could feel as hot as 109 degrees outside.
The advisory covers Prince William County, Manassas, Manassas Park, Stafford, Fredericksburg, and surrounding areas and will remain in place from 11 a.m. to 8 p.m. Friday, July 25, 2025. Forecasters say actual temperatures will climb into the upper 90s, with high humidity pushing heat index values into dangerous territory.
Thousands lost power Wednesday night as severe thunderstorms rolled through Northern Virginia. As of 5:30 a.m. Thursday, about 850 NOVEC customers remained without electricity, down from a peak of 7,000. Reported outages include 79 in Prince William County, 63 in Stafford, 561 in Fauquier, and 136 in Loudoun. Dominion Energy reported 24 outages in Prince William and more than 500 in Fauquier.
At the same time, the National Weather Service issued a Flood Warning that remains in effect until 8:30 a.m. after heavy rainfall—up to 4.5 inches in some areas—caused creeks and streams to overflow. Roads in parts of Manassas, Manassas Park, Haymarket, Nokesville, and Gainesville were flooded, and emergency officials warn that some crossings remain impassable.
A strong cold front moving into the region on Tuesday is expected to bring widespread showers and thunderstorms, with the potential for flooding and damaging winds during the afternoon and evening hours.
According to the National Weather Service, conditions will become increasingly unstable throughout the day, leading to likely thunderstorm activity after 4 p.m. Forecasters say the setup could produce repeated rounds of storms, raising the risk of flash flooding in low-lying and urban areas. A Flood Watch may be issued ahead of the storm’s arrival.
Warm, humid weather will give way to scattered thunderstorms this afternoon as a weak cold front drifts through the region, according to the National Weather Service.
Forecasters say the day will start mostly sunny with highs reaching the upper 80s to low 90s, but the combination of heat and moisture will create unstable conditions leading to thunderstorm development. Areas west of the Blue Ridge and into the Shenandoah Valley could see storms as early as noon, while the D.C. and Baltimore metro areas can expect storm chances between 2 and 8 p.m.
A ridge of high pressure remains in place, keeping the region hot and humid today. Scattered thunderstorms are likely to develop this afternoon and evening, bringing the risk of heavy rain, damaging wind gusts, and frequent lightning. With high moisture levels and slow-moving storms, localized flash flooding—especially east of the Blue Ridge and along the I-95 corridor—is a real concern. A Heat Advisory remains in effect until 7 p.m., with heat index values reaching 102 to 107 degrees.
