 Lower humidity today, making the heat more tolerable. We're close to 90 this afternoon. Clouds increase later today with a low of 73. Tomorrow, we have rain developing in the morning, heavy at times. Then it becomes scattered in the afternoon. But listen out for thunder. There's at least isolated lightning possible tomorrow. Not as hot on Friday at the high of 80, but back to 90 on Saturday. I'm meteorologist Ava Marie on WBAL News Radio 1090 and FM 101.5.
