Key Factors
- 01 Blizzard Warning in effect until 6:00 PM EST with travel 'very difficult to impossible' and emergency-only travel advised
- 02 Heavy snow at 1-3+ inches per hour through about 11 AM, with 9 to 13 inches of new accumulation possible
- 03 Gusts as high as 45 mph and sustained north winds of 17-29 mph causing blowing snow, drifting and reduced visibility
- 04 Areas of blowing snow forecast all day and through the night, even as precipitation chances fall below 20% after 3 PM
- 05 Temperatures of 29-34 F with wind chills as low as 14 F; heavy wet snow may cause downed trees, power lines and outages
- 06 Overnight temperatures drop to about 20 F, so refreezing and icy or drifted roads are likely after dark
- 07 Visibility values and road treatment status are not provided, which adds uncertainty

Recommendation
Avoid driving today unless it is an emergency. Do not travel 6 AM-12 PM (heaviest snow) or during the blizzard through 6 PM. If travel is unavoidable, the least-bad windows are roughly 2-5 PM in the afternoon and, for the evening, 5-6 PM only after checking 511 for road conditions, though roads may be unplowed and drifting. Evening travel after 6 PM risks refreezing and lingering blowing snow. Carry a winter survival kit and stay with your vehicle if stranded.
