After Thursday night's rain caused flooding in some areas, the National Weather Service issued a hazardous weather outlook for much of Maryland Friday, as more thunderstorms may roll through.

"An isolated severe thunderstorm with damaging wind gusts is possible this afternoon," forecasters advised.

Heat Wave Ahead

After the potential for rain, prepare for some heat: Daytime highs will be near the 90s through next week as the season's first heat wave arrives.
