CHEYENNE, Wyo. — Southeast Wyoming is experiencing a notable warmup with well-above-average temperatures and dry conditions expected to continue from Wednesday through Friday, according to the National Weather Service in Cheyenne.
The area is bracing for elevated to near-critical fire weather concerns due to the warm temperatures, dry conditions and gusty winds, especially across portions of southeast Wyoming and western Nebraska on Thursday and Friday afternoons.
The NWS in Cheyenne is also monitoring the potential for another storm system which could impact the Rocky Mountain region over the weekend, potentially bringing cooler temperatures.
In the short term, as upper-level ridging takes hold, Cheyenne and surrounding areas will see drier air and warmer temperatures through Wednesday night. Forecast highs are expected to climb to the upper 50s to upper 60s, with an isolated chance of temperatures exceeding 70 degrees in some parts of the High Plains.
Wind conditions will start strong but are forecast to weaken by Wednesday, shifting from north/northwesterly to westerly.
Looking toward the weekend, a shift in the weather pattern is anticipated. A broad longwave trough moving into the western United States could lead to moderate to heavy precipitation across southeast Wyoming and western Nebraska from Saturday afternoon through Sunday.
However, forecast confidence remains low due to variability in the timing and strength of this system, with temperatures likely to drop back to near or slightly below average by the weekend.
