Temperatures stayed above freezing Saturday but the weekend weather will not remain warm for long, according to the National Weather Service, which issued a winter storm watch for Howard County and much of the Baltimore-Washington area.
A winter storm watch means there is potential for significant accumulations of snow, sleet or ice that could make travel hazardous, the weather service reported.
The forecast called for rain Sunday afternoon in Howard County, changing to snow overnight. Five inches of snow—or more—may accumulate, the weather service said.
Temperatures will fall below freezing Monday, with roads becoming snow-covered and slippery before the morning commute, according to the weather service.
The heaviest snowfall will be on Monday morning, the weather service reported.
