Thunderstorms and strong winds are expected to sweep across the Baltimore region Thursday, and mild temperatures are forecast to drop throughout the day, according to the National Weather Service.
Forecasters predict heavy rain Thursday from a line of active thunderstorms moving across Maryland in the morning hours.
Gusty winds are also possible as a cold front moves through behind the storms. Winds are expected to come from the southwest at 20 to 30 mph, and could gust up to 40 mph.
While temperatures reached the mid-50s by late Thursday morning, they are forecast to fall to 40 degrees by evening, according to the National Weather Service.
About half an inch of rain fell overnight and into Thursday morning, and another half an inch to an inch of rain is possible by early afternoon. The heaviest rain is forecast to the west of Interstate 95.
Because the ground is frozen after days of frigid temperatures, excess runoff could flood streams and low-lying urban areas, the National Weather Service said. A flood watch is in effect from through Thursday afternoon.
Forecasters say another cold front will cross the region Friday, bringing a slight chance of snow showers with it.
