Key Factors
- 01 No active weather alerts
- 02 Precipitation chance is 0-2% all day, so no new snow, rain or freezing rain is forecast
- 03 Temperatures of 25-31F from 7am to 11am mean any residual moisture, frost or refrozen meltwater could leave black ice on bridges, overpasses and shaded roads
- 04 Temperatures rise above freezing from about noon (33F) and peak near 40F around 5pm, reducing ice risk
- 05 Winds are light at 2-7 mph with no significant gusts, so crosswind risk is minimal
- 06 Temperatures fall back to 32-34F after 9pm and the overnight low is around 28F, so ice may return late evening into overnight
- 07 Visibility data is not provided, but the sky forecasts (sunny to partly cloudy) suggest no fog or visibility hazard; road surface conditions are also not provided

Recommendation
Safest morning window is 11am-12pm, when temperatures climb to 31-33F (earlier is fine with caution for black ice). Safest evening window is 4pm-7pm, when temperatures are 38-40F and skies are clear. Avoid or use extra caution on bridges and shaded roads before 10am and after 9pm when temperatures are near or below freezing.
