CHEYENNE, Wyo. — Cheyenne wrapped up October with below-average precipitation, record-breaking warmth early in the month and a sharp cooldown by the month’s end. According to the National Weather Service in Cheyenne, the capital city saw a high of 85 degrees on Oct. 2, which broke the daily record for that date and tied the all-time October high set on Oct. 9, 1910.
A Warm October, Followed by a Cold Snap
The month’s average high of 67.5 degrees was notably above the usual October high of 59.1 degrees. Many days saw highs in the 70s and 80s, culminating in the record-breaking 85 degrees on Oct. 2, the warmest day of the month.
This early warmth did not persist, however. By month’s end, temperatures took a dramatic dip, with Oct. 31 recording the lowest temperature of the month at 25 degrees. The first freeze of the year hit Oct. 25 with an observed low of 30 degrees. This chilly close to October contrasts sharply with Cheyenne’s historic October low of -5 degrees, recorded on Oct. 26, 1878.
Winter Approaches, Bringing Precipitation
Despite warmer-than-average temperatures for most of October, Cheyenne experienced a significant precipitation deficit. Total precipitation for the month reached only 0.12 inches, far below the October average of 1.00 inches. Snowfall was also limited, with just 0.5 inches recorded, well short of the October average of 5.9 inches.
As November begins, forecasters are noting increased chances of snow and colder weather, signaling a potentially more active start to winter.
