Key Factors
- 01 Light rain likely from 7am to around 4pm (precipitation probability 60–80%), increasing stopping distances and reducing visibility/traction.
- 02 Temperatures drop from the low/mid-50s to around 40°F in the afternoon, and to near/freezing (around 39–38°F) after 6pm, raising the risk of rain/snow mix and slick surfaces.
- 03 Snow is likely late day/early evening: 'Light Snow Likely' from 6pm–7pm with 57% precipitation probability, and 'Snow likely before 7pm' in the overnight narrative.
- 04 Wind: northwest winds 14–17 mph with gusts up to 33 mph during the daytime can create crosswind issues for high-profile vehicles.

Recommendation
Drive only if necessary. Safer morning window: 8:00–10:00 AM (rain persists but temperatures are higher, reducing ice risk). Safer evening window: 7:00–8:00 PM is preferable if you must travel (snow risk is greatest before/around 7pm, then precip probability drops sharply afterward).
