.SHORT TERM /THROUGH SATURDAY/...
Issued at 307 PM MDT Thu Apr 23 2026

High winds continue to trend downward this afternoon as the first
upper-level shortwave moves eastward out of the CWA. Winds continue
to gust over 50 MPH, so High Wind Warnings will stay in effect until
their expirations this evening. Once the sun sets, winds will ease
overnight. Blustery conditions will remain at the typical wind prone
areas overnight as a secondary shortwave drops in from the north.
Besides the wind, radar shows weak scattered showers across much of
the forecast area. Some observations sites are reporting light
precipitation, however a majority of the precipitation is not
reaching the ground due to the dry low-levels. This will change
later this evening as the aforementioned secondary shortwave moves
into the area.

Tonight, Hi-Res guidance shows pretty good precipitation chances for
the northern zones as the secondary shortwave skirts our northern
border. Temperatures overnight will be below freezing, so snow is
likely. Accumulations are also possible from Douglas to Chadron and
points northward. Accumulations will be on the lighter side, with
the most likely amounts ranging from a dusting to an inch.
However, cannot rule out a few locations further north seeing up
to 3 inches when this event is done Friday morning.

Lingering moisture and energy around on Friday will spark another
round of scattered showers during the day. There are a few hundred
joules of CAPE as indicated by model soundings, so showers will be
convective in nature. Given that most profiles across the area show
inverted-v`s, cannot rule out strong gusty winds in these showers.
During the evening hours, a weak cold front will push down from the
north, diminishing shower activity across the area.

Cooler temperatures are expected Saturday behind the front. High
temperatures will be in the 40s and 50s across the area which is
roughly below average for most of the forecast area. Saturday will
be similar to Friday as energy from the trough aloft triggers
scattered showers during the day. However, precipitation chances
will increase Saturday night as the next system moves into the
area.

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Issued at 307 PM MDT Thu Apr 23 2026

Saturday night-Sunday...Looks like some much needed precipitation as
a slow moving trough aloft moves overhead, and with a moist airmass
and low level upslope enhancing lift, we expect widespread showers
to affect the forecast area. Somewhat cooler compared to Saturday
with all the cloud cover and expected precipitation.

Monday...Zonal flow aloft continues and with enough low and mid
level moisture and upslope low level lift, we expect scattered to
numerous showers and a few thunderstorms due to the instability.

Tuesday...Northwest flow aloft moves overhead, and with adequate low
and mid level moisture, we anticipate scattered showers and a few
thunderstorms. Slightly warmer based on 700 mb temperature trends.

Wednesday...The next trough aloft moves to southern California with
northwest flow aloft over our forecast area. With some increase in
low and mid level moisture, we anticipate an increase in areal
coverage of showers and some thunderstorms. Temperatures about the
same as on Tuesday.

Thursday...Another shortwave trough aloft moves across Montana, with
our west northwest flow weakening across our forecast area. With
adequate low and mid level moisture in the atmosphere, and the lift
from the approaching shortwave trough, we anticipate scattered to
numerous showers and some thunderstorms to develop. Continued cool
temperatures based on the cloud cover and precipitation
coverage.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 1145 PM MDT Thu Apr 23 2026

Active weather is anticipated at terminal locations tonight and
tomorrow. An area of showers and thunderstorms are moving
through our northern WY counties into the NE Panhandle and
should be impacting KCDR shortly. Reduced visibilities are
being reported at a few weather stations west of KCDR, so it is
possible these low visibilities impact the terminal and send
CIGS to IVF. KAIA may also experience lower ceilings in the
next few hours. Variable surface winds at KCYS are expected to
create llws given the stronger flow aloft overnight. KLAR may
also experience some llws concerns around day break. As a
coldfront moves into our area, expect winds ahead of it to pick
up starting at KRWL and spread east to impact all terminals in
the afternoon and evening. Wind gusts of 30-40 kts out of the W
before the cold front shifts the winds out of the north or
northwest. An area of showers are expected to develop in the NE
Panhandle this afternoon which may impact KBFF and KCDR.
Ceilings also lower following the coldfront at the end of the
forecast period, possibly approaching MVFR.
