Vermont Weekend Winter Storm: First Alert Weather Day Issued
Summary:
A significant winter weather system will impact Vermont, New York, and New Hampshire this weekend, prompting WCAX to declare a First Alert Weather Day for Sunday. The storm features a dangerous mix of freezing rain, snow, and ice accumulation with precipitation beginning Saturday evening (4-8 PM across regions) and peaking Sunday morning. Highest impacts include slippery travel conditions, potential ice accumulation up to 0.1 inches in mountainous areas, and 1-12″ of snow accumulation at higher elevations. Temperatures will drop steadily throughout Sunday, creating refreezing hazards even after initial precipitation subsides.
What This Means for You:
- Immediate Road Hazard Preparation: Apply ice melt/sand to driveways and walkways by Saturday afternoon, especially in Adirondack, Green Mountain, and Northeast Kingdom regions facing highest ice risks
- Travel Window Adjustment: Avoid mountain travel after 4 PM Saturday through Monday morning due to reduced visibility and snow-packed roads; check 511VT for real-time road conditions
- Emergency Alert Configuration: Download the First Alert Weather App with location-specific alerts enabled for winter weather advisories
- Secondary Freeze Warning: Anticipate black ice formation Sunday afternoon as temperatures plummet through the 30s, even in valleys where rain transitions to snow
Original Post:
BURLINGTON, Vt. (WCAX) – We’re tracking substantial wintry precipitation beginning Saturday evening with peak impacts Sunday. The National Weather Service has issued winter weather advisories starting 4 PM Saturday in New York and 7 PM Saturday in VT/NH.
Precipitation Phasing: Initial freezing rain transitions to rain valleys/snow mountains Sunday AM, then all areas to snow by afternoon. Mountain passes will experience moderate-heavy snow accumulation rates (>1″/hour) Sunday PM.
Critical Infrastructure Impacts: Untreated surfaces will develop glare ice by sunrise Sunday. Secondary roadways in elevations >1,000ft face particular risk of snow compaction into ice layers beneath subsequent snowfall.
Monitor real-time updates through the First Alert Weather App with hyperlocal ice accretion modeling and road temperature sensors.

People Also Ask About:
- When will roads be safest? Saturday before 3 PM offers the last clear travel window before precipitation begins.
- Which areas get worst ice? Northern Champlain Valley and eastern foothills face highest freezing rain accretion potential.
- Are power outages likely? Ice under 0.25″ poses minimal grid risk but may weigh down untreated tree limbs.
- How cold will it get? Low 30s Sunday afternoon creates flash freeze risk; teens expected overnight Sunday.
Expert Opinion:
“This storm exemplifies classic nor’easter precipitation phasing challenges,” notes Senior Meteorologist Gunnar Consol. “The critical transition from freezing rain to heavy snow in mountainous terrain creates layered ice-snow surfaces, disproportionately impacting high-elevation transportation corridors. Historical analogs suggest unexpected black ice development in valley exit ramps where runoff refreezes Sunday afternoon.”
