From the Summit County Citizens Voice (Bob Berwyn):
At 0.5 inches, precipitation [ed. in Dillon] for the month was slightly less than half of average (1.06 inches, with measurable rain or snow on only six days. And despite the cool temps, the snow total for the month (3 inches) was also slightly less than have of average (7.7 inches)…
In Breckenridge, long-time weather observer Rick Bly tallied 8 inches of snow in October, just 63 percent of average (12.3 inches) — and that that’s not the best sign for the winter, based on past statistics. Snow and rain combined added up to just 0.72 inches of moisture, which is 57 percent of average. For Bly, October is the best indicator month for the rest of the season, and 70 percent of the time, a below-average October is followed by below-average snowfall for the winter.
Here’s the October Climate Summary from the National Weather Service.
