- Its scoring rule requires all five atmospheric conditions to align; shallow valley fog remains difficult for models to resolve.
Field notes
Each hourly check looks for five conditions: cloud below the summit, clear dry air above, a temperature inversion, light winds and high pressure. Scores are grouped as likely at 60+, possible at 35–59, outside chance at 15–34, and unlikely below 15. The page names Open-Meteo and several national models as data sources, with updates hourly.
