Flash flooding in Washington D.C. after severe storms.
Washington D.C. is recovering from severe storms that have caused flash flooding, particularly in areas west of the city. Although the immediate threat has lessened, isolated showers may continue. Residents are warned of potential flooding and strong winds as severe weather is expected to return, with predictions of scattered storms and uncomfortable heat in the coming days. Health advisories are also noted due to moderate pollen levels.
Washington D.C. and surrounding areas are recovering from heavy storms that triggered flash flooding, especially in regions west of the city. As of now, the immediate threat has diminished; however, isolated showers or storms may continue throughout the night. Meteorologists predict lows tonight to hover between 70 and 75 degrees, setting the stage for more significant weather disruptions expected tomorrow.
Looking ahead, severe weather is forecasted to return, with showers and storms likely causing flooding and strong winds. Residents should prepare for similar weather conditions on Monday, as humid air will persist in the region, maintaining the threat of downpours through the middle of the upcoming week. The National Weather Service has issued flash flooding warnings, particularly affecting areas like Reston, McLean, and Potomac, valid until 8:00 PM EDT.
Reports of over 2 inches of rainfall have emerged from Potomac, Maryland, and around Reston, Virginia. The National Weather Service recorded instances of high water at Hunter Mill Road beneath the 267 Toll Road. Concerns remain as a stubborn thunderstorm lingers over northern Fairfax and southern Montgomery counties, causing havoc with rainfall rates that are expected to reach 1 to 2 inches in just 30 minutes. Additionally, gusty winds exceeding 50 mph are anticipated through the night, increasing the urgency for residents to stay indoors and to avoid driving on flooded roads.
Tomorrow, Sunday, the forecast indicates a mix of clouds and sunshine, with possibilities of isolated showers throughout the day. The afternoon may see hit-or-miss storms capable of producing flooding rains and strong winds. Highs are expected to climb into the mid-80s to near 90 degrees. Tomorrow night, scattered showers and storms are peculiar, with conditions likely easing later on. Lows will remain in the 70 to 75 degree region, accompanied by increased cloud cover and potential patchy fog.
Confidence in the forecast for both Sunday and Monday is rated as Medium-High, signaling a stable meteorological pattern but with uncertainties typical of such climatic events.
As Monday approaches, the weather will likely worsen, with predictions for widespread showers and storms further exacerbated by high humidity levels, contributing to potential flooding. High temperatures on Monday are expected to be in the mid-80s, continuing the trend of warm summer conditions. On Tuesday, conditions may shift slightly to sunnier weather with lower odds of storms, although isolated showers remain a possibility.
The forecast for Wednesday through Friday indicates high temperatures could reach near or exceed the 90-degree mark. Consequently, afternoon heat index values are projected to fall in the mid- to upper 90s, potentially leading to uncomfortable conditions.
