.SHORT TERM /THROUGH MONDAY NIGHT/...
Issued at 129 PM MST Sat Nov 14 2026

A gloomy rest of the day is in store for us, as SE upslope flow is
in place along and east of the I-25 corridor. This has resulted in
rather widespread fog and low clouds throughout this morning, with
some gradual clearing being observed via visible satellite imagery
especially across portions of Laramie and Platte Counties in SE
Wyoming. Low clouds and fog looks to linger in some areas of the NE
Panhandle mainly south of the Pine Ridge, with a handful of
locations currently observing visibilities between 1/2 to 1 mile.
Overall expecting a gradual, but slight lifting of cloud bases from
west to east throughout the afternoon, however most locations will
still be impacted by at least some low cloud cover before the onset
of more fog development after sunset into the overnight period. As
many locations across the Nebraska Panhandle are still underneath a
thick layer of low clouds, decreased high temperatures by around 5
degrees, with most locations east of the I-25 corridor struggling to
get out of the 40s (which is actually normal for this time of
year!).

A weak shortwave trough will continue to dig south and east of our
area this evening and overnight, with the bulk of the forcing for
ascent remaining well to our south in portions of Colorado. Overall,
kept PoPs low (15-20%) for portions along and south of the I-80
corridor where some showers may manage to creep into our area from
the south, though these are expected to be quite spotty and
shouldn`t amount to much in the way of beneficial moisture. One
exception will be over the higher terrain of the Sierra Madre and
Snowy Ranges, where there are currently some weak (<25 dBZ) radar
returns, though not confident that much is making it to surface as
mesonet observations are reporting 15-20 degree surface dewpoint
depressions and WYDOT cameras aren`t showing anything evident. Kept
the highest PoPs (40-50%) over these higher elevations before
06Z as the system gradually move out of our area, but don`t
think anything will amount to much more than 1-2 inches of snow
(if anything) on the mountain peaks.

For the lower elevations east of the Laramie Range, fog and poor
visibilities will be the main hazard overnight under the upslope
flow regime. Not confident in how widespread or dense the fog will
be, but can anticipate a similar pattern to last night into early
this morning which warranted a Dense Fog Advisory for much of the
Nebraska Panhandle along with portions of Platte and Goshen
Counties. Unlike today, expecting a faster dissipation of fog and
low clouds tomorrow morning as 500 mb height rises and ridging
builds in across much of the Central United States. As a result,
tomorrow should be 5-10 degrees warmer than today, peaking in the
mid to upper 50s east of the I-25 corridor, with slightly cooler
upper 40s to low 50s to the west. Similar to the past couple of
days, may need to bump forecast highs down a bit in areas where low
clouds manage to hang on a bit longer.

Can expect further warming heading into the beginning of the work
week as the ridge continues to amplify to our east, placing us in SW
flow aloft. Dry conditions will persist through Monday, with highs
potentially reaching the low to mid 60s east of the Laramie
Range.

.LONG TERM /TUESDAY THROUGH FRIDAY/...
Issued at 129 PM MST Sat Nov 14 2026

The majority of the long term will feature relatively benign weather
with a return to more seasonable temperatures and breezy conditions.
Picking up on Tuesday, this will likely be the last day of above
average temperatures as the ridge continues to push eastward away
from the CWA. High temperatures will be in the 50s and 60s which is
still anywhere from 10 to 15 degrees above average for mid-November.

A pattern change will arrive on Wednesday as a trough swings into
the Rockies. A cold front will move across the area, late Tuesday
night or early Wednesday morning, leading to high temperatures in
the 40s and 50s--roughly average for this time of year. This front
will be mostly dry, with predominately west winds promoting a dry
downslope environment. The mountains, however, could see a quick
shot of snow, with the Sierra Madre Range picking up a few inches of
accumulation. The Snowys will likely be shadowed and not see much in
the way of accumulations. The bigger concern with the frontal
passage will be strong winds. Marginal high winds will be possible
as MSLP gradients compress from the front. Winds aloft will increase
up to about 50 kts with decent subsidence, so cannot rule out 60 MPH
gusts during the day in the typical southeast Wyoming wind prones.

Seasonal temperatures will stick around on Thursday with little to
no weather impacts expected. Some lingering breezy conditions are
still likely west of the Laramie Range on Thursday, but the rest of
the forecast area will see a quiet day. Friday into the weekend,
things could get interesting with a potential impactful winter
storm. Of course, its still over a week away with plenty of time for
models to come to a solution, but there is a chance for accumulating
snow and windy conditions.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1056 AM MST Sat Nov 14 2026

Low-level southerly flow is advecting moisture into the region,
creating areas of fog and low stratus east of the Laramie Range.
MVFR to IFR conditions will continue through the afternoon and into
the overnight due to reduced visibility and low CIGs. There may
be brief improvements to CIGs this evening, but it will not
last as upslope flow continues across the region. Fog may return
to areas east of the Laramie Range Sunday morning.
