Why clouds can decide your night
Aurora happens far above weather clouds. A strong display can still be hidden from the ground.
Activity is not visibility
A high activity forecast cannot remove a cloud layer. Total cloud-cover percentages describe a model grid area, not the exact view above a parking space.
Look for meaningful differences
Compare nearby locations over the same time window, and avoid assuming small percentage differences are significant. Low, middle and high cloud forecasts can add context, but all layers can interfere with viewing.
Check again before leaving
Weather forecasts change and terrain complicates local conditions. If every nearby location is forecast to be cloudy, a long drive may not improve the situation.
