After a sunny start today, couds bubbled up into scattered showers and some storms across the area that have lasted into evening. Rainfall continues scattered, but has been locally heavy in stronger storms. Highs that ranged from the low-to-high 90s allowed us to reach our second 3-day stretch of 90+ in D.C. this year and set a record high at Dulles of 98.

Through Tonight: Scattered showers and storms may persist till late evening before things quiet down for the rest of the night. Thanks in part to rising levels of humidity, lows should only make it to the lower 70s in the suburbs and the mid-or-upper 70s downtown.

Tomorrow (Wednesday): We should be cloudier than today though still rather warm to hot. Highs range from the upper 80s to lower 90s and humidity will be high. Scattered afternoon or evening showers and thunderstorms will be possible as a front approaches the area.

Tropics: Hurricane Bill continues to organize out in the Atlantic. Winds increased a bit today, from 100 to 110 mph (5 p.m. advisory), as the Category 2 storm heads WNW on track to miss the islands of the Caribbean. Bill should become a major hurricane (defined as Category 3 or higher) in the next day while beginning to turn more toward the north. Right now, it appears the East Coast of the United States should be safe and miss out on a hit, but it's worth keeping watch as things can change. Visit our Hurricane Tracking Center.

Heavy downpours developing near D.C. now. One is moving along the beltway to the North of the District, another is coming down Route 66 into Arlington and possibly into the city in the next hour. Heavy rain, lightning, are main threats with these.

Dulles set a new record high today at 98F. Pretty impressive heat across the area today.
