Area Forecast Discussion
National Weather Service Riverton WY
342 PM MST Sun Feb 28 2021

.SHORT TERM...(This evening through Monday night)
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
usual Wind Corridor, as well as the Cody Foothills. The winds in
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.

.LONG TERM...(Tuesday through Sunday)
Issued at 107 PM MST Sun Feb 28 2021

Dominant ridge will continue to influence the region for the long
term. Main noticeable weather feature will be the much warmer
temperatures, with highs east of the divide running at least 10
degrees above normal, with plenty of 50s and 60s for the latter
half of the week. Models to note a cutoff low cutting under the
ridge across the Four Corners on Thursday. Right now, models keep
it far enough south to only bring an increase in clouds for far
southern WY Thursday, with an outside chance of flurries/drizzle
during the day. After this, models continue with the ridge across
the Rockies, and are having trouble agreeing on where the next
trough will go later next weekend.
