.SHORT TERM /THROUGH SUNDAY/...
Issued at 200 AM MST Fri Nov 13 2026

Forecast remains on track into this weekend, so not many changes
made to the previous forecast package with relatively quiet
weather lingering through Sunday. This morning, surface
observations and current 10.3-3.9 fog product loop shows low
clouds and fog starting to roll into western Nebraska at this
hour with Alliance now down to 4 miles VIS with low stratus near
400 feet AGL. Fog product shows this area of low clouds/fog
slowly drifting westward and will likely impact most of western
Nebraska, in some form, through 800 AM Friday morning...and may
event impact Torrington and the lower elevations of Goshen and
possibly Platte County by sunrise. Increased the coverage of fog
to for most areas near and east of the Wyoming/Nebraska border
this morning. Fog should lift and clear out between 8 and 10 AM.
Not expecting persistent dense fog at this time, so may handle
any locally dense fog with a Special Wx Statement early this
morning if visibilities lower any more than a half mile.

For the rest of today (Friday), the high amplitude upper level
ridge axis will move overhead this morning along with increasing
high cloudiness. Should be a pleasant afternoon with high
temperatures remaining in the upper 50s to mid 60s across most
of the area, coolest temperatures could actually be over the
western Nebraska panhandle depending on how quick the low
clouds dissipate. Mildest temperatures will likely be located
along and just east of the I-25 corridor.

For this weekend, models remain in good agreement, showing the
next Pacific storm system moving across the Great Basin Region
Friday night and gradually into the central Front Range on
Saturday. With a dominate southern branch of the upper level
jet, expect this system to split and likely remain south of us
into Saturday night with the northern portion weakening over
Montana. Another round of fog and/or low clouds likely across
most of western Nebraska and far eastern Wyoming Friday night
and early Saturday due to increasing upslope southeast winds
ahead of this storm system, so continued to increase coverage of
fog across the eastern half of the forecast area. Some
precipitation can`t be ruled out for the I-80 corridor, but
chances are pretty low with maybe a few inches of snow for the
Sierra Madre and Snowy Ranges Saturday evening. Temperatures
will begin to lower on Saturday with a cooler airmass working
its way into the region. High temperatures in the upper 40s to
mid 50s expected due to cloud cover and upslope south to
southeast winds. The Pacific storm system will gradually weaken
and eject eastward on Sunday, leading to a slightly warmer day
with dry conditions and light west to southwest winds.

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
Issued at 1206 PM MST Thu Nov 12 2026

Monday...The flow aloft backs to southwest, inducing surface lee
troughing across our forecast area, and producing a continued
warming trend as 700 mb temperatures rise to near 6 Celsius.
Continued dry with limited low and mid level moisture.

Tuesday...Looks like a breezy to windy day as the flow aloft
strengthens in advance of an approaching shortwave trough aloft from
Utah and Arizona. Low and mid level moisture still looks too scant
for any precipitation to reach the ground.

Wednesday...A progressive negatively tilted shortwave trough aloft
will move across our counties, spreading chances for showers from
west to east, with somewhat drier conditions by late afternoon in
the wake of the shortwave trough aloft.

Thursday...Fast southwest flow aloft develops again ahead of the
closed low aloft across Idaho and Nevada. Looks like enough synoptic
and mesoscale lift and adequate moisture to produce showers
spreading from west to east, until the late afternoon when
subsidence behind the shortwave trough aloft will make it drier. 700
mb temperatures suggest temperatures will be somewhat similar when
compared to Wednesday.

.AVIATION /12Z TAFS THROUGH 12Z SATURDAY/...
Issued at 447 AM MST Fri Nov 13 2026

Upper level ridge axis will move over the forecast area today with
increasing high cloudiness. Patchy to areas of fog this morning
across mainly western Nebraska with VIS below 2 miles, lifting
shortly after sunrise.

HAZARDS/WEATHER TRENDS: IFR to LIFR conditions will persist across
the western Nebraska terminals due to low CIGS and fog. Most
confident across KAIA, KBFF, and KSNY...although the current
thinking is KBFF will likely lift shortly with high clouds moving
into the region. Either way, VFR conditions expected after 16z after
the fog and low CIGS lift between 15z and 17z. Winds will become
breezy out of the south for most terminals late this morning (17z)
through this afternoon.

Another round of low CIGS and patchy fog possible later tonight
after 06z across the high plains. This may also impact KCYS after
09z Saturday bringing IFR or lower conditions through 12z Saturday.
