I can see the logic, but you’ll need a strict protocol to avoid guessing. Light changes are useful if you correlate them with pressure and wind shifts, but you must test it over months. A quick rule: if the ridge lights dim sharply before sunrise, it’s usually a frontal passage. Use that as one data point, not the only one, and always keep backup sensors. That way you give hikers a reliable warning without putting their safety on a single observation.
