 Rick McClure, WTOP Traffic. All right, thanks, Rick. And now over to 7 News First Alert meteorologist Mark Pena. The chance at a spotty shower storm is there through about sunset tonight, otherwise turning mostly clear, mild, and muggy. Temperatures falling into the mid-70s by tomorrow morning. Now, your Monday afternoon will be a bit of an active day. We've got high temperatures near 100 degrees during the afternoon. Heat index values will make it feel closer to 110. That's why the National Weather Service has an excessive heat warning.
