10 p.m. update: Flash flood warning for parts of Montgomery and Howard county described below discontinued. Scattered strong storms are a continued risk overnight, however - throughout the metro region.

9 p.m. update: Strong to severe thunderstorms have hammered portions of northern Loudoun, Montgomery, and Howard county this evening with reports of strong winds and small hail. Torrential rain has fallen for an extended period in north central Montgomery county (around Montgomery Village) and west central Howard county, prompting a Flash Flood Warning through 11:45 p.m. Scattered thunderstorms, mainly north of the District, are likely to continue for at least a couple more hours. Per the forecast below, there’s a chance of more storms towards morning.

Original: Another day, another 95 or higher afternoon temperature in Washington, D.C. Today’s 95+ reading is the 27th of 2012, tying 2010 and 1981 for 2nd place, with plenty of summer to go (1 away from record of 28 in 1980). The current hot streak (10 straight 90+ days) may end Friday as clouds and showers and storms hold back temperatures.

Through Tonight: Through dark, showers and storms are isolated around D.C., while more concentrated in the mountains to the northwest. Overnight, we may see a few more storms in the immediate metro region, but odds are less than 50/50. Generally, it’s partly cloudy and warm, with lows 70-75 (suburbs-city)

Friday: It’s setting up to be a volatile day. A few showers and storms are possible in the morning (20-30 percent chance), but we may well break out with some sunshine by late morning into the afternoon. Depending on the amount of sun, we might touch 90, or fall just shy. Shower and thunderstorms are likely (80 percent chance) in the afternoon and evening, a few of which may be severe with damaging winds and hail. An isolated tornado also cannot be ruled out. Heavy rain and lightning are likely in storms that develop.
