Key Factors
- 01 Slight chance of rain showers in the morning (about 15–19% hourly PoP 7–10 AM; daily forecast notes showers before ~10 AM), which could make roads briefly damp.
- 02 Daytime temperatures are well above freezing (upper 30s rising to around 50F), reducing ice risk during the day.
- 03 Breezy northwest winds (up to ~12 mph with gusts up to ~22 mph) could cause minor handling issues, especially for high-profile vehicles.
- 04 Temperatures fall into the 30s late evening (down to ~37F by 11 PM) and a Freeze Warning is expected to start around midnight tonight (risk of icy spots increases after the forecast day, especially on bridges/untreated surfaces).
- 05 No visibility data (fog/low visibility) is provided, so confidence is reduced slightly.

Recommendation
Morning safer window: 10:00 AM–12:00 PM (after the early shower chance tapers). Evening safer window: 6:00 PM–9:00 PM (dry/mostly clear; try to finish travel before late-night temperatures approach freezing and before the Freeze Warning period begins after midnight).
