One to two inches of snow may fall, with two-tenths of an inch of ice accumulating before Monday morning, according to the National Weather Service.
The forecast shows the following for Baltimore County on Sunday:
- Snow before 2 p.m.
- Snow and sleet from 2 to 5 p.m.
- Snow and freezing rain after 5 p.m.
- Rain, freezing rain and sleet before 11 p.m.
- Rain after 2 a.m. Monday
Power outages are also possible since the mixture of "snow and ice has the potential to coat trees and tree limbs, which may then fall onto power lines..." Carol Dodson, vice president of BGE, said. "Some outages may be extended if hazardous road conditions delay our crews’ ability to travel and begin restoration work."
The winter weather advisory is in effect from 8 a.m. Sunday to 7 a.m. Monday in Anne Arundel, Baltimore, Charles, Harford and Prince George's counties.
A winter storm warning is also effective for areas west of Interstate 95, according to the weather service. "Significant ice accumulations" are likely, particularly in the evening when the precipitation has shifted to freezing rain.
Temperatures in Baltimore County Sunday will stay in the low 30s.
