 We're going with a heat alert and there are heat advisories up for pretty much the entire area from noon until 8 p.m. Can't rule out an isolated thunderstorm. Better chance of storms Wednesday with also more heat. I'm 7 News Chief Meteorologist Veronica Johnson in the First Alert Weather Center. Coming right up Tuesday morning after traffic and weather in the midnight hour. Hundreds of people in Falls Church are unable to cool off, even in their own homes. I'm Cheyenne Crenn.
