.DISCUSSION...
Issued at 1254 AM MST Wed Dec 4 2024

The calendar may say December but temperatures across portions of
the Cowboy State on Tuesday certainly did not feel like it. Some
locations of note were Lander and Cody where highs neared record
values. Lander reached 59 degrees coming within 2 degrees of tying
the record high of 61 set back in 1941 and Cody hit 63 degrees.
Temperatures across the CWA today are still expected to be 10 to 20
degrees above normal but likely not to the degree they were on
Tuesday. Highs are forecast to be in the mid 40s to low 50s east of
the Divide and in the upper 30s west of the Divide. Lingering
snowpack is leading to these cooler temperatures west of the Divide.
The cooler temperatures may lead to some patchy fog developing this
morning especially in portions of Star Valley, Jackson Hole, and
Sweetwater County. Overall, mild and quiet conditions prevail
through the remainder of the week.

Looking ahead towards the end of the week and weekend. A weak
shortwave nears the region for the end of the week but models
currently show the only impacts being some breezy winds. However,
this weak disturbance looks to be the prelude to a better chance for
widespread precipitation by the end of the weekend. The area of
potent ridging that is keeping dry and mild conditions in place
looks to gradually break down over the weekend. Long range models
have continued to show a disturbance moving into the region by the
end of the weekend. There is a lot of uncertainty regarding this
system with little agreement among any of the major models. While
there is not a general consensus among model, things are starting to
trend towards a weaker, less organized system. Models seem to be
trending towards a lower impact event with the best chance for snow
being across the higher elevations. However, there is still time for
things to shift one way or another but as of right now chances are
not looking favorable for a widespread impactful snow event.

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 920 PM MST Tue Dec 3 2024

VFR conditions are generally expected to persist at all TAF
sites, though KJAC and maybe KRKS could drop to IFR conditions
with fog Wednesday morning, just like Tuesday morning. The best
chance seems to be at KJAC for the hours just before and after
sunrise. Breezy and gusty west-southwest winds should continue
at KCPR through sunset, then decrease overnight. High clouds
are will filter over the area through the night, primarily
across central and eastern WY. Breezy and gusty winds will pick
up again at KCPR around 15Z. After the fog burns off during
mid- to late-morning Wednesday, western WY should see mostly
clear skies with light winds.

Please see the Aviation Weather Center and/or CWSU ZDV and ZLC for
the latest information on smoke, icing, and turbulence forecasts.
