Warm stretch ahead for Cheyenne; fire weather warnings possible

(John Roedel, Cap City News)

CHEYENNE, Wyo. — In southeast Wyoming and western Nebraska, the weather forecast from the National Weather Service in Cheyenne promises a stretch of unusually warm and dry conditions leading into the weekend, with critical fire weather concerns on the horizon.

As the week progresses, temperatures are expected to soar above average, reaching highs in the upper 50s to 70s through Friday. These conditions come as a result of upper-level ridging that encourages drier air and warmer temperatures.

Meanwhile, gusty winds will pose the primary weather impact on Wednesday, potentially reaching gusts of 30–40 mph, with an isolated 50 mph gust not out of the question, particularly between Cheyenne and Rawlins.

By Thursday, the ridge axis is predicted to shift east, further increasing temperatures across the High Plains. Coupled with a 700 millibar jet stream pushing into south-central Wyoming, wind gusts could ramp up through the day, reaching 40–50 mph. These gusty winds, alongside the dry conditions, will elevate fire weather concerns, especially in portions of Carbon County, where near-critical fire weather conditions are expected.

Heading into the weekend, the NWS in Cheyenne is closely monitoring a developing storm system that could bring cooler temperatures and a return to more seasonal weather patterns.

The potential for mountain snowfall and a notable spring snow event along and east of Interstate 25 looms, contingent upon the trajectory and strength of the approaching system. The forecast suggests that areas in the mountains of southeast Wyoming could see over 6 inches of snow, with a possible significant snow event for regions along and east of I-25.

As the storm system progresses, cooler weather and partly to mostly cloudy conditions are anticipated into the early part of next week, with the added possibility of widespread high winds across the region, particularly on Sunday.
