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.

The Baltimore region is expected to see a bit of a warmup Wednesday after a few days of bitter cold.

A wind advisory along the Interstate 95 corridor was canceled, and instead shifted to the Eastern Shore, where gusts could reach 50 mph.

The rainfall could be enough to put this month’s precipitation ahead of normal, continuing a wet weather trend that dominated 2018.

There has been 1.85 inches of rain so far this month at Baltimore-Washington International Thurgood Marshall Airport, and the norm for January is about 3 inches of precipitation.

There has been 7.5 inches of snow at BWI, slightly ahead of normal for the month of January.
