Precipitation will overspread the state from west to east this afternoon and evening. In the mountains, it will start as snow, while further east, rain will develop and slowly transition to snow during the overnight.

By tomorrow morning, all areas west of the Bay will have transitioned to snow. Areas around and east of I-95 may mix with rain at times tomorrow morning, but the snow will continue, heavy at times through the day and into tomorrow night. Lower southern Maryland and the Eastern Shore will see more rain and have more mixing, cutting down storm totals. By tomorrow night, even these areas will see a period of all snow before it begins to taper off.

A weak storm system will spread light snow over the state this afternoon from west to east. 4-6 inches of snow are expected over Garrett County, while 1-3 inches are expected within the Advisory areas.

There could be isolated higher amounts, especially across northern Maryland and Southern Maryland.

As mentioned yesterday, the low pressure that will bring snow to the area today and tonight will have a sharp dropoff of precipitation on the northern edge. As such, some areas will see flurries while others receive several inches of snow over a relatively short distance.

It appears that dividing line will setup across central Maryland today. Areas north of Baltimore will see little to no accumulation while in the counties to the south of the city, a Winter Weather Advisory is in effect for 1-3 inches of snow with the highest amounts the further south you go.

Strong Cold Front Brings Rain and Wind

An intense area of low pressure continues to strengthen over the midwest while it drags a cold front across the country. The front will approach the area this afternoon spreading rain into the area by sunset.

The rain will be heavy at times, accompanied with strong gusty winds. A thunderstorm is possible during the overnight as well.

Winter begins at 6:12 tomorrow morning and the front will be pushing through around that time. Expect wind gusts to near 40mph tomorrow, as temperatures fall from the low 40s into the 30s during the day.

Winter Weather Advisory in effect

The entire state west of the Bay is under a Winter Weather Advisory for snow, sleet and freezing rain.

Garrett County is expected to see more accumulation of snow and ice, and is under a Winter Storm Warning.
