PM Update: More Showers & Storms for Some
Muggy Friday along with PM thunderstorm threats
Sunshine has given way to some isolated to scattered showers and storms, and they should continue into early evening before dwindling. While the entire metro area is at risk for at least a passing shower or storm, much of the focus looks to be on northern and western parts. The strongest storms will be capable of heavy rain, intense lightning and perhaps strong winds. Highs near or above 90 in most spots and sticky dew points near 70 continue to make it quite tropical. Dulles has recorded its 6th straight day of 90 or above.
Through Tonight: Isolated to scattered showers and thunderstorms, especially north and west of the District, last into early evening. Some storms could be quite strong. Shower and storm chances should decrease significantly by around 8 p.m. or so, with just a stray shower possible overnight. Lows will range from the lower-to-middle 70s.
Tomorrow (Friday): Friday should be mostly cloudy with the chance of an isolated shower through the morning, then scattered showers and storms developing during the afternoon into evening. It appears afternoon/evening storm coverage could be more widespread tomorrow, and a few storms could be intense. Highs should reach the upper 80s to near 90.
Summer Storms: In the heart of summer, severe weather is often more isolated than when strong cold fronts are more common fare. But high heat and humidity can lead to very intense activity on a local scale. On Tuesday, CWG's Andrew Freedman witnessed an intense storm (see his aftermath photos: 1 | 2) that targeted New York City with straight-line microburst winds which knocked about 100 trees over in Central Park. Last night, an isolated supercell thunderstorm hit St. Mary's County, Md., leading to a tornado warning and several reports of very large hail.
