Key Factors
- 01 Blizzard Warning active until 6:00 PM EST (extreme severity; travel should be restricted to emergencies only).
- 02 Hourly forecast calls for Heavy Snow And Areas Of Blowing Snow from 6:00 AM through at least midday, with precipitation probabilities mostly 80–96% early.
- 03 Winds from the north 25–29 mph early, with gusts reported up to 45 mph; gusty winds can create drifting and dangerous crosswinds.
- 04 Snowfall accumulation expected: 9–13 inches possible through the day; snow is likely to stick and cause power/obstruction hazards (trees/power lines).
- 05 Temperatures near freezing (upper 20s to mid-30s) increase risk of slick surfaces as snow/packed snow persists.
