By late evening, the rain risk is largely done, and the overnight story is humidity. Through Tonight: Very slow-moving showers and storms have been around the region much of the day. There are hints this activity may be more widespread than what we saw today, but it doesn’t look like a big, severe weather event. Places which saw the most clouds or some rain were generally the ones that missed 90. We’ll see more and more clouds bubble with time, and that brings another afternoon storm risk to the area.
