CHEYENNE, Wyo. — Residents can expect scattered showers and thunderstorms today and tonight. The National Weather Service in Cheyenne is warning of strong wind gusts reaching 55–65 mph. These winds are likely this afternoon and early evening.
Today’s weather will be warm but unsettled. Morning temperatures will start in the lower 50s and rise to highs in the upper 60s and lower 70s. The first round of showers and thunderstorms is expected this morning, and a second wave will develop in the mid- to late afternoon, particularly in Carbon and Albany counties.
Wind gusts will be strong, and cloud bases will be around 10,000 feet. This could lead to some convective clusters, or upward movement of heat and moisture, increasing the wind threat. The cool and unsettled weather will persist through Thursday as mid-level energy drifts slowly south.
The long-term forecast remains uncertain. Models disagree on the evolution of weather systems from the late week into the weekend. Expect breezy conditions Saturday, with temperatures in the upper 60s to low 80s both Friday and Saturday. The weekend may see intermittent ridging, or increased atmospheric pressure, aloft and potential isolated showers by Monday.
