Forecasters warn that snow accumulation in the region could range from four to eight inches, with the heaviest snowfall expected during the afternoon and evening hours.
The NWS Baltimore-Washington office tweeted, "A winter storm will impact the region Sunday with accumulating snow likely. Travel could become hazardous, so plan accordingly."
Officials said that there may be sleet and snow in some areas until approximately 2 p.m. on Jan. 19 before it transitions to snow.
In northern Virginia and central Maryland, conditions are projected to deteriorate rapidly, with snow-covered roads and reduced visibility making travel hazardous.
Residents in Frederick County, Loudoun County, and surrounding areas are advised to limit non-essential travel during the storm.
Following the snow, an arctic air mass will move into the area, sending temperatures into the teens on Monday and even lower overnight.
Wind chills could dip into the single digits or below zero, heightening the risk of frostbite and hypothermia for anyone outside for extended periods.
State officials are urging residents to take precautions, including having an emergency kit ready with food, water, and flashlights in case of power outages.
Additionally, pet owners are reminded to keep animals indoors during the extreme cold.
The NWS also noted that these conditions could create dangerous black ice on roadways and sidewalks as snow melts and refreezes.
"Plan ahead and stay informed through reliable sources," they tweeted, sharing safety tips and weather updates for the region.
The winter storm is expected to affect much of the Mid-Atlantic, but Maryland and Virginia are likely to bear the brunt of its impact.
