Key Factors
- 01 Slight chance of rain showers (15-19%) from 7am to 10am; wet roads possible but temperatures are 38-44F, so no ice from rain
- 02 Frost Advisory until 8am: early-morning frost possible on untreated surfaces, bridges, or windshields, but air temps are already 38F by 7am
- 03 Freeze Warning starts at midnight tonight (low near 30F, as low as 26F); any lingering moisture could refreeze after midnight into Tuesday morning
- 04 Winds NW 2-12 mph with gusts up to 22 mph in the afternoon; minor crosswind concern for high-profile vehicles only
- 05 Precipitation chances are 0-10% from 11am onward, with clear skies tonight
- 06 No visibility data provided; no fog alerts are active, and nothing in the forecast suggests fog

Recommendation
Morning: drive 10am-12pm, after the shower chance ends and any frost has melted. Before 8am, clear frost from windshields and use caution on bridges and shaded spots. Evening: drive 6pm-10pm, when skies are clear, winds are easing and temperatures are 39-46F. Avoid late-night driving after midnight, when sub-freezing temperatures could cause patchy ice on bridges or damp spots. Expect afternoon gusts near 22 mph if driving a high-profile vehicle.
