Key Factors
- 01 Frost Advisory expired at 8 AM; residual frost/black ice risk possible on untreated surfaces early morning
- 02 Freeze Warning active tonight (from midnight) into Tuesday morning, with overnight lows near 30F - not a concern for daytime driving today but relevant for late evening/early morning trips
- 03 Slight chance of rain showers (15-19% PoP) through mid-morning, minimal accumulation expected
- 04 Daytime winds light (5-12 mph) with gusts up to 22 mph, minor crosswind risk for high-profile vehicles
- 05 Visibility not explicitly reported, but no fog or low-visibility alerts issued, reducing but not eliminating uncertainty
- 06 Temperatures fall through the day from 51F high to near freezing by midnight, increasing ice risk late at night

Recommendation
Morning drive is fine after 9-10 AM once any residual frost has melted and rain chances drop; evening drive is safest between 5 PM and 8 PM before temperatures fall toward freezing overnight. Avoid driving after 11 PM into early Tuesday morning due to Freeze Warning and potential ice formation.
