Heavy Snowfall, Rapid Freeze, and Dangerous Wind Chills Expected Across Maryland as Winter Storm Intensifies

MARYLAND — A powerful winter storm is setting up to deliver heavy overnight snowfall, rapidly falling temperatures, and dangerous wind chills across Maryland and the Mid-Atlantic, with the heaviest totals expected from Baltimore to Philadelphia. Updated model guidance shows a sharper, colder setup than earlier forecasts, raising the potential for a significant snow burst late Saturday into early Sunday.

Final Snowfall Forecast Shows 2–6 Inches for Central Maryland

Analysis of updated snowfall projections indicates a wide spread of totals across the region:

• Baltimore, BWI, Annapolis, and central Maryland: 2” to 4”
• Northern Maryland into York, Lancaster, Philadelphia, and Wilmington: 3” to 6”
• Frederick, Westminster, Hereford regions: Positioned in the mid-range zone
• Far western Maryland and mountainous areas: 6 inches or more

Areas south toward Washington, D.C., Easton, and Salisbury may stay closer to the 1” to 3” range depending on how quickly temperatures fall.

Forecasters warn that temperatures begin warm, which may delay accumulation at first. However, the cold rush arriving behind the storm will allow snow to stick rapidly overnight, creating hazardous travel by early Sunday.

Overnight Snow Burst Expected as Arctic Air Arrives

Model simulations show a potent snow burst developing between 2 a.m. and sunrise Sunday, stretching from Baltimore to York, Harrisburg, and Philadelphia.

• A concentrated band of moderate to heavy snow is expected to sweep eastward.
• Rain and mixed precipitation will flip to snow quickly.
• Accumulation rates may briefly exceed 1 inch per hour in the heaviest zones.

By 10 a.m. Sunday, the main snow shield will be pushing toward the coast, leaving lingering snow showers behind it, especially across northern Maryland and southern Pennsylvania.

This timing means the worst conditions will occur overnight and early Sunday morning, when road temperatures begin to plummet.

Wind Chills Near or Below Zero to Follow the Storm

Once the snow exits, an Arctic air mass will surge into the region.
Wind chill projections for Sunday afternoon include:

• 0° to 10° across much of Maryland
• Below zero in western Maryland and higher terrain
• 10s to 20s toward coastal areas of Delaware and New Jersey

These conditions will make Sunday feel dramatically colder than the actual air temperature and may cause rapid refreezing on untreated surfaces.

What This Means for Maryland Residents

With a mix of heavy snow, a quick transition from rain, and an Arctic blast, this storm may bring:

• Hazardous overnight travel
• Icy roads early Sunday
• Reduced visibility during the snow burst
• Possible school or event disruptions depending on Sunday morning conditions

Residents planning to travel or attend early events should prepare for delays and rapidly changing conditions.
