Key Factors
- 01 Blizzard Warning (Extreme severity) for Mercer, Middlesex, Morris and Somerset Counties, with total snow of 18 to 25 inches and gusts up to 45 mph; the warning text says it runs from 10 AM today to 6 PM Monday, while the alert data's end time field reads 10 AM today
- 02 Rain and snow mix this morning (35-39% rising to 54% precipitation chance 6-10 AM) with temps 34-36F, so wet or slushy roads are likely as the storm begins
- 03 Heavy snow starts around 3 PM, with rates possibly over 2 inches per hour and areas of blowing snow from 6 PM onward, sharply cutting visibility
- 04 Temperatures fall to 31-32F by evening, so wet roads can freeze and snow will accumulate quickly
- 05 Winds rise from 3 mph this morning to 24 mph by midnight, with gusts up to 46 mph overnight, causing drifting and crosswind danger
- 06 Forecast totals: 1-3 inches by 6 PM and 15-21 inches overnight; the storm continues through Monday's commutes
- 07 Impacts include tree branches down and isolated power outages

Recommendation
Avoid non-emergency driving today; travel is restricted to emergencies only per the warning. If you must go out, the safest window is early morning, roughly 6-9 AM, before snow intensifies and while winds are light, and finish any trips by about noon. Evening is not recommended: conditions are worst from 6 PM onward, so be off the roads and home by about 2 PM. Carry a winter survival kit, stay with your vehicle if stranded, and check 511 for road conditions.
