A team of three Pennsylvania meteorologists is now providing a coast-to-coast sunset quality forecast.
The team behind SunsetWx has already published a thorough methodology of its algorithm and a case study of successfully predicted "vivid" sunsets its first day of forecasting last week. Basically, the model blends high-resolution forecasts of humidity, pressure changes, and clouds at various levels of the atmosphere, weighting wispy upper-level clouds the strongest and penalizing for thick, low-level clouds or average clear sky evenings.
They totally called Sunday's bonkers NYC sunset, so maybe they're worth a follow. Sunset photo by @AirlineFlyer.
