 leaving us partly cloudy. Could be some patches of fog, if not too breezy. Upper 60s, low 70s. A better day on Thursday, about 10 degrees cooler in the upper 80s to near 90, with less humidity in the afternoon. Friday looks sweet, 85 sunshine, lower humidity, but more heat, humidity, and a threat of storms for the coming weekend. I'm WTOP meteorologist Howard Bernstein.
