A clipper system moving through the Baltimore area Thursday could bring snow showers before the temperatures drop into the teens overnight, the National Weather Service said.
The weather service projected a 40 percent chance of snow for much of the day Thursday, from 10 a.m. until 6 p.m., and winds gusts of up to 29 mph.
The high for the day is 38 degrees, and that could drop to a low of 16 at night, with wind chills in the single digits, as two separate blasts of Arctic air move through the city this weekend.
Clouds and any precipitation should clear by Friday, only to be followed by a low pressure systme that could result in more snow or a wintry mix Saturday and next week.
Two men have died in Baltimore from the cold in recent months, bringing the number of winter-weather deaths to six in the city and 19 statewide this season, the Baltimore City Health Department said Wednesday.
The city declared an extended "Code Blue" advisory for Thursday through Monday, expanding homeless services to prevent further hypothermia deaths.
