Parkways, city streets and areas with poor drainage could become flooded Wednesday as a storm deposits as much as 3 inches of rain on the Hudson Valley, the National Weather Service's New York forecast office said.

Only a few days removed from icy precipitation and bone-chilling temperatures, the region will likely see the mercury rise to the high 50s during the day Wednesday. Rain is expected throughout the morning, accompanied by fog in some areas.

Rains will continue into Wednesday night, forecasts predict, with thunderstorms and 30 mph wind gusts.

The National Weather Service issued a flash flood warning for Wednesday for much of the Hudson Valley, including Westchester, Orange and Rockland counties, and the flooding could be more extensive farther north in Dutchess and Ulster counties, meteorologists warned.

East of the Hudson River, that could mean flooding on the Saw Mill, Bronx River and Taconic parkways, and urban areas as far north as Poughkeepsie and Kingston could see localized flooding, according to forecasts.
