Key Factors
- 01 No active weather alerts are listed.
- 02 No hourly precipitation is indicated (hourly probability of precipitation is 0 at all times provided).
- 03 Winds are breezy, with NW winds around 15–16 mph and gusts reported up to 26 mph during the day (can affect vehicle handling, especially high-profile vehicles).
- 04 Temperatures are at/near freezing in the early morning (30–32°F from 7–10am) and fall to around 29°F in the evening-to-late period (potential for black ice if roads get damp).
- 05 There is a discrepancy in the daily forecast: daily period 2 shows precipitation probability = 1, but the hourly forecast shows 0 throughout; this reduces confidence about late-day precipitation risk.

Recommendation
Safer to drive during the warmer part of the day: 10:00am–12:00pm (temps ~35–39°F, winds steady). For the evening, use 5:00pm–6:00pm (temps ~45→43°F); avoid late-night driving after ~9:00pm since temperatures trend down toward the upper 20s and any unexpected moisture could increase slick-road risk.
