 Back to the P.J. Fitzpatrick Home Improvement Weather Desk. Enjoy no interest financing for 12 months. On to 7 News First Alert Meteorologist Steve Rudman. A severe thunderstorm watch until 10 o'clock this evening, although I do suspect it will come down a little bit early for parts of it. We also have an excessive heat warning until 8 p.m. for the metro area and southern Maryland. Feels like temperatures will drop into the 90s once the storm's clear.
