claude-haiku-4-5 Analysis · Feb 28, 2026
Patchy fog and freezing fog with black ice risk dominate the early morning hours (before 9am) due to temperatures below freezing and recent snowmelt, but conditions improve significantly after 9am with mostly sunny skies for the rest of the day.
- 01 Patchy fog present at 6-9am with high relative humidity (92-96%) and sub-freezing temperatures creating freezing fog risk
- 02 Black ice likely from Friday snowmelt on pavement with near-freezing early morning temperatures
- 03 Reduced visibility hazard specific to early morning hours before 9am
- 04 Conditions improve markedly after 9am with temperatures rising and fog clearing
- 05 Winds are light throughout (1-6 mph), posing minimal crosswind hazard
- 06 No precipitation expected during daylight hours
Avoid driving between 6am-9am if possible due to patchy fog, freezing fog, and black ice risk. If travel is necessary during this window, use headlights on low beam, reduce speed significantly, and maintain extra following distance. Safe driving window: 10am-5pm with clear sunny conditions and temperatures above 35F. Evening driving after 5pm is acceptable with partly cloudy skies and diminishing hazards, though watch for potential black ice re-formation after sunset as temperatures approach freezing.
