The first snowflakes of the season fell at the summit level of the High Knob Massif during evening hours of 30 October 2020, as cold air was transported into the mountains in wake of heavy rains associated with former hurricane Zeta.
Air temperatures fell into the low-mid 20s within colder, high valleys of the massif by morning hours of Halloween as low clouds dissipated. The first traces of rime formed in highest gaps and on peaks prior to cloud evaporation.
