Well that was a fun start to the day for the Nebraska Panhandle.
Basically as the low pressure system was wrapping up and pushing
North-northeast a little band of FGEN (area of enhanced
rain/snowfall) set up over the southern panhandle that no model was
tracking correctly. Due to the band of enhanced rainfall the
temperatures dropped and the rain transitioned to snowfall a lot
faster than anticipated. A last minute SPS was issued for the
Western portion of the Panhandle for localized 1-3 inches that may
cause some possible delays. There was a report of 3 inches on the
border of the Banner and Scotts Bluff county to confirm the SPS was
needed. Mid-level water vapor showed dry air eventually being
ingested by the Low pressure system eventually causing the showers
to slowly dissipate in the southern half of the Panhandle. Dawes
county is currently the last county with active snow showers but
those should eventually stop around 3pm-ish. However, with all this
low level moisture and an area of high pressure following in the
systems wake, the cloud cover may resurface overnight for the
Panhandle and the far eastern side of the SOutheast Wyoming area.
This overnight cloud cover though will keep us relatively warmer
overnight with temperatures in the mid to upper 30`s with some areas
reaching around 40 degrees. Another system is making landfall over
the pacific northwest which will compress the gradient as it runs
into our area of high pressure. Meaning tomorrow morning it will be
fairly windy west of the I-25 corridor between Rawlins and Laramie
as the 700mb jet creeps up to speeds around 55 knots and diurnal
mixing starts to occur. Wind gusts up to 60 mph may be likely along
that wind prone stretch of I-80 but wind gusts between 50 to 55 mph
may be more likely. These gusty winds will taper down from those
elevated gusts through the afternoon but it will be fairly breezy
through the overnight hours. Temperatures are expected to be in the
50`s and 60`s by Tuesday afternoon but the mountain peaks will stay
closer to the mid 30`s during the afternoon hours. The models have
some overnight clouds pushing through Tuesday night as that system
from the Pacific Northwest climbs back into the Canadian providences
as it goes up and over our area of developing high pressure. If any
clouds remain over our forecast area overnight then the spots
underneath those clouds may be a touch warmer that forecasted.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 129 AM MDT Mon Oct 26 2026

Medium Range models remain in good agreement for much of mid to
late week as weak to moderate southwest flow aloft dominates the
weather pattern across the northern Front Range. With a lack of
Pacific (shortwave) energy embedded in the mean southwest flow
aloft through Friday, expect generally dry conditions
and mild temperatures Wednesday through Friday as the polar jet
stream will remain well to the north, and the subtropical jet
should stay well south of the region near the Mexico/USA border and
into Texas. Since southeast Wyoming and western Nebraska will be in
between storm tracks, relatively mild temperatures are expected
through the end of the week with afternoon highs in the upper 50s to
upper 60s. Temperatures should peak Friday afternoon as 700mb
temperatures climb over 5c ahead of the next Pacific storm system
moving onshore, with a few locations possibly reaching 70 degrees
east of the Interstate 25 corridor.

Deterministic models are in better agreement for next weekend,
but ensembles still depict relatively low confidence with
precipitation chances...mainly due to the evolution and speed
of the Pacific energy moving onshore. Thankfully, with the
Pacific energy trending a little slower, Halloween evening looks
decent with maybe a few rain showers in the evening.
Temperatures should be relatively mild for this time of the year
in the upper 30s to upper 40s between sunset and 10:00 PM.
Winds appear light and variable and should result in a pleasant
evening. Models do show the first of a series of upper level
disturbances lifting northward across the area on Halloween, but
the system is pretty progressive with the best dynamics located
north and west of the I-25 corridor. A more potent system is
forecast to arrive on Sunday and continue early next week. Model
solutions and ensemble members diverge significantly with this
storm system, so will not go into too much detail at this time.
However, temperatures will trend cooler and likely below average
for this time of the year by next Sunday and Monday.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 558 PM MDT Mon Oct 26 2026

Low stratus and fog are expected tonight, mainly for terminals east
of the Laramie Range. South to southeast winds overnight will keep
low stratus persistent across the area. MVFR to IFR CIGs are
expected at western Nebraska terminals and KCYS. Fog is also
expected to develop later tonight from light winds and ample surface
moisture from rain and snow that fell during the day. Fog and low
CIGs will continue into Tuesday morning, with conditions
gradually improving as the day progresses.
