 That said, in the next couple of hours, we could see this broken line of showers at that point make it to the D.C. metro. And at that point, we could see some hit and miss rain showers with some embedded lightning, not expecting anything severe. Now, that said, as we head farther into the night, drying out, temperatures falling into the mid-70s by tomorrow morning, and it'll be rather muggy. For tomorrow, a cold front approaches. It'll be hotter and more humid than today. Temperatures in the mid to upper 90s are expected, with heat index values making it feel about 100 to 105.
