Thunderstorms and a slight chance of severe weather could complicate this afternoon's rush hour, according to the National Weather Service.

"We may get some brief downpours that could cause ponding on roads and drainage problems, so drivers need to use caution," said Lee Hendricks, a meteorologist with the National Weather Service.

This morning's rush hour was slower than normal because of heavy rain. By 7 a.m., a quarter inch of rain had fallen at Pittsburgh International Airport.

The fast rain briefly closed a section of Route 65 near Sewickley and caused some flooding on roads near Morgantown, W.Va. Traffic on Route 28 slowed down near the 31st Street Bridge because of ponding near a construction area along the highway.

This afternoon, scattered thunderstorms are likely between 2 p.m. and 7 p.m. Rain will end by midday Thursday and could return Friday night and early Saturday.

On Sunday, the weather service says, there is a chance of snow showers.
