Area forecast discussion, Feb 21, 3:43 PM MST, 4 hours 10 minutes before
Area Forecast Discussion
National Weather Service Cheyenne WY
343 PM MST Tue Feb 21 2017
.SHORT TERM...(This evening through Wednesday night)
Issued at 343 PM MST Tue Feb 21 2017
Winds easing over the area this afternoon as the gradient likewise
is slackening. Expect a fairly quiet night across the CWA with
some increase in cloudiness mainly out west. Snow showers will
persist over the higher mtns as moisture rides up the west-facing
slopes.
One more mild day across the CWA Weds ahead of an upper trough
that will be over the western CONUS. Sctd rain and snow showers
will continue over far western parts of the CWA during the day as
the moisture feed continues over that area. Should see a slow
increase in clouds elsewhere. Meanwhile a lee cyclone will begin
developing over eastern Colorado by late in the day. More
significant changes should ensue Weds night as the lee cyclone
continues to deepen over eastern Colorado and colder air sinks
south across the CWA. Some diffluent upper flow and jet dynamics
should allow for an increasing area of snow with some banding
expected. Main problem will be the location of the heavier bands.
Models continue trend of shifting heavier activity a little
northward. Given trends in models have advanced the Winter Storm
Watch over the higher mtns to early Weds morning then started a WS
Watch over most of the rest of the CWA Weds night.
.LONG TERM...(Thursday through Tuesday)
Issued at 343 PM MST Tue Feb 21 2017
Significant winter storm is still on track for late Wednesday night
through Thursday night, taking aim at the CWA. The biggest change
in the 12Z guidance compared to previous cycles was a northward
shift in the axis of heaviest QPF, away from areas along the
Colorado Border, and toward the northern half of the CWA. Large
scale ascent (QG convergence) really gets going between 03-06Z
Thurs. There will likely be some banding also as the GFS indicates
good midlvl frontogenesis and elevated instability. Went ahead and
issued a Winter Storm Watch for almost the entire CWA with
widespread 6-12 inches over lower elevations. Was least confident
about amounts in areas along Interstate 80 due to the aforementioned
northward shift in the best forcing. Patchy blowing snow will be
possible through the event, especially by Thursday aftn/evening as
the pressure gradient strengthens and north winds gust to 30-35 mph.
Snow will begin to decrease in intensity by late Thursday evening
and into the night. The remainder of the extended will feature
below normal temps in northwesterly flow aloft, however it will be
mostly dry after Friday morning.
&&
.AVIATION...(For the 18Z TAFS through 18Z Tuesday Morning)
Issued at 230 PM MST Mon Feb 20 2017
VFR conditions will prevail overall through the period. Strong/gusty
winds expected for most terminals this afternoon, especially in
southeast Wyoming where gusts of 45-55 knots are possible through
this afternoon. Winds easing through the evening.

wetter conditions over the next few days.
