Temperatures are expected to stay below freezing Tuesday, with blustery breezes bringing wind chills in the single digits, according to the National Weather Service.
High pressure and cold air are settling over the region, bringing sunny skies yet cold temperatures. Temperatures are expected to drop to the teens and lower 20s overnight across the region, rising to the mid- to upper-20s by afternoon.
Winds of 20-30 mph are expected to make it feel as cold as the low teens by the afternoon.
BWI Marshall Airport bottomed out at 18 degrees Tuesday morning, according to the weather service. With gusts as strong as 38 mph, recorded in the 7 a.m. hour, it felt as cold as 3 degrees below zero.
More of the same is expected Wednesday and Thursday, with a chance for wintry precipitation arriving Friday.
The weather service's five-day forecast for downtown Baltimore calls for temperatures to remain no higher than the upper 20s through Saturday, with lows forecast to drop to 11 degrees by Friday and Saturday nights.
Over the past three years, BWI has reached the single digits only twice, reaching 8 degrees both times, Jan. 24, 2011, and Jan. 31, 2010. In the couple of years before that, the cold was more common, with a coldest point of 2 degrees Jan. 17, 2009.
