A line of strong storms moved through the D.C. area Monday evening.
The storms produced damaging winds and lightning and prompted several severe thunderstorm warnings and watches through the evening.
In the 12000 block of Whippoorwill Lane in Rockville, Md., a lightning strike set fire to the roof of a single-family home. No injuries or damage estimates were reported.
There also were reports of some power outages, trees or tree limbs down, and road closures in the area.
Don't expect the rain to provide much relief from the heat for very long. The storms will pass overnight, according to NBC Washington Chief Meteorologist Doug Kammerer, and a heat advisory will be in effect from noon until 8 p.m. Tuesday.
