Key Factors
- 01 Special Weather Statement for patchy/freezing fog and possible black ice from snowmelt early this morning
- 02 Temperatures below freezing (28F) from 6-8am with 96% humidity, raising ice and reduced-visibility risk
- 03 Fog expected to clear by about 9am as temperatures rise above freezing (35F)
- 04 Daytime is dry (precip chance 1-2%), sunny, with light winds 1-6 mph and no wind hazard
- 05 Evening cools back toward freezing (31F low overnight), so refreeze of any wet surfaces is possible after dark

Recommendation
Avoid driving before 9am due to patchy freezing fog and black ice; if you must, slow down, use low beams, and increase following distance. Safest morning window is 10am-12pm after fog clears and temps rise. Best evening window is 5pm-7pm before temperatures drop back toward freezing; use caution later as surfaces may refreeze overnight.
