CHEYENNE, Wyo. — Residents across Cheyenne and surrounding areas are preparing for a shift in weather patterns as a storm system is poised to bring cooler temperatures, accumulating mountain snow and valley rain or snow showers from Wednesday into Thursday.

Tuesday marks the end of a stretch of above-average regional temperatures, according to the National Weather Service in Cheyenne. With the influence of an upper-level ridge and under southwest flow, areas east of the Laramie Range and the Nebraska Panhandle are set to enjoy another day of warmth, potentially reaching into the 60s in snow-free zones. However, anticipation grows as the storm system from the west promises a significant change.

By late Tuesday and escalating into Wednesday, the storm system begins its march into Carbon County. The Sierra Madre mountains are braced for a prolonged snow event, with up to 14 inches anticipated, prompting the issuance of a winter storm watch. In contrast, the Snowy Range may see lesser accumulations due to being in the shadow of this westerly flow.

As the storm system progresses, scattered rain and snow showers are expected to extend beyond the mountains, with minimal accumulations predicted for the valleys. The focus then shifts to the long-term forecast, where a convoluted pattern suggests unsettled weather could persist through the weekend, introducing cooler temperatures and daily precipitation chances, particularly in higher elevations.

Key Takeaways for Cheyenne:

  • Enjoy the last of the warm temperatures on Tuesday before the storm hits.
  • Prepare for gusty winds and a mix of rain and snow showers from Wednesday into Thursday.
  • Anticipate cooler, below-average temperatures starting Thursday and lasting through the weekend.
