PM Update: Showers roll by through tonight, with some thunder possible
As long as you weren’t watching the markets, it was a beautiful day. Temperatures reaching the mid-70s are pretty close to normal. Humidity is low. Sunshine has been plentiful, at least until clouds took over this afternoon. All quite ideal for the time of year. Our weather does take a turn tonight, but fortunately it’s a brief one. We’ll be back to sunshine tomorrow. Temperatures also start rising toward our first heat wave of the year.
Through Tonight: Clouds increase this evening as a quick-hitting storm system approaches the area. Some brief showers are possible this evening. A steadier light to moderate rain becomes a good bet in the hours nearing midnight, especially north of the city. There could be a thunderstorm mixed in as well. It seems the heaviest precipitation will tend to focus over northern Maryland or north. Temperatures fall to within a few degrees either side of 60. Winds are light from the south.
Tomorrow (Thursday): If you’re up early, there could be a passing shower scurrying out of here. Clouds clear out with time, and we end up mainly sunny during the afternoon. Highs shoot for the mid-80s as humidity returns to early summerlike levels. Winds are from the west around 10 mph, with gusts near 20 mph.
