Issued at 107 PM MST Sun Feb 28 2021

Drier and warmer conditions will end the month as ridging builds
into the area. Currently, mostly clear skies are observed over the
CWA, with the only thing to note being some gusty winds in the

the Cody Foothills may persist into early Monday morning as the
surface pressure gradient remains tighter, but gusts should stay
below high wind criteria. High temperatures will be more
seasonable as we begin March, with clear skies and continued gusty
conditions in the Wind Corridor.
