Key Factors
- 01 Winter Weather Advisory for mixed precipitation (up to 1 inch snow, light glaze of ice); the alert's end time is listed as 7 AM in the structured field but the text says 7 AM to 3 PM EST, so the longer window is assumed
- 02 Temperatures 28-32F before 10 AM with snow and a slight chance of freezing rain between 7 and 10 AM raise the risk of icy or slick surfaces
- 03 Patchy fog forecast at 7-8 AM and again from 10 AM to about 1 PM may reduce visibility; no visibility values are provided
- 04 Precipitation chance climbs to 81-96% from 10 AM through the afternoon as snow changes to rain near 33-37F, leaving wet or slushy roads and possible refreezing on untreated surfaces
- 05 Steady rain continues into the night (quarter to half inch possible) with temperatures 37-38F, so ice risk is low but wet-road hazards remain
- 06 Winds are light (2-5 mph), so wind is not a concern

Recommendation
If possible, delay non-essential travel until conditions improve. Safer windows are roughly 6:00-7:00 AM (before the advisory and heavier precipitation, though temperatures are 28F so watch for untreated icy spots) and 4:00-6:00 PM when temperatures are 37F and only light rain is expected. Avoid 8 AM-3 PM when mixed precipitation, fog and slippery roads are most likely. If you must drive, slow down, increase following distance, use low beams, and check 511 for road conditions.
