- 03 Temperatures stay near freezing (mid-30s dropping to ~31–32°F), increasing risk of slick roads/ice even where rain/snow transitions occur.
- 04 Strong winds increasing through the afternoon/evening: gusts referenced in the alert up to 45 mph; hourly winds rise to 18–24 mph by evening/night (NE).

Recommendation
Morning: avoid driving if possible, but if you must, travel early before the worst conditions—prioritize a window around 7:00–9:00 AM. Evening: do not drive during the main hazardous period; if travel is unavoidable, delay until after conditions ease (based on this data, conditions are hazardous from ~3:00 PM through late night).
