Another day of unseasonably mild temperatures is in the forecast Wednesday, though without Tuesday's sunshine. Chances of showers are forecast throughout the day, with strong thunderstorms possible late, according to the National Weather Service.
Lows are forecast in the upper 40s and highs in the upper 60s. More than an inch of rain is possible, most of it in the afternoon and evening as storms pass through ahead of a strong cold front.
A flash flood watch is in effect for Central Maryland from 3 p.m. through late tonight. Forecasters expect most of the rain to fall over a short period, causing urban flooding. A special weather statement for the region cautions of winds up to 40 mph by late afternoon and possibly 60 mph as storms pass through, dropping as much as 1-3 inches of rain.
A coastal flood watch was in effect for Wednesday evening along the western shore of the Chesapeake Bay, with high tides 2-3 feet above normal possible.
Wind gusts of 35-40 mph are expected in the evening, with still stiff gusts of 20-25 mph throughout the day.
Once the cold front passes through, wintry weather is expected to return. Temperatures are expected to drop 20-30 degrees, with lows back in the 20s Thursday through the weekend and highs in the 30s and 40s.
