.SHORT TERM /THROUGH SUNDAY/...
Issued at 333 PM MDT Fri Apr 24 2026

Observations currently show a cold front draped across the northern
part of the CWA, roughly along a line extending from Douglas to
Glendo to Harrison and points northward. Temperatures behind the
slow moving front are in the 30s and are on the moister side. Here,
weak radar returns and ground observations show scattered light snow
showers. South of this front, conditions are warmer and dryer.
Temperatures are sitting in the 50s and 60s for most locations.
Radar also shows weak echoes, however, the dry surface and low-
levels are likely preventing a lot of this precipitation from making
it to the ground as ground observations are not yet reporting rain.
Shower activity will continue throughout the afternoon and into
the early evening. However, showers will dissipate later this
evening as the cold front gradually pushes south into Colorado.
Cannot rule out another round of light snow for the northern
zones overnight as a weak pulse of energy comes off the
stationary trough sitting over Saskatchewan. Accumulations will
be possible, however it will likely not be greater than an inch.

Temperatures across much of the area will be cooler behind the cold
front on Saturday. High temperatures will generally be in the 40s
and 50s which is cooler than average for most locations. Hi-Res
guidance keeps conditions dry throughout much of the day, however
some showers could start to develop later in the afternoon ahead of
the next Pacific system. Precipitation chances increase headed into
Saturday night as the shortwave associated with the next system
moves into southern Nevada. With ample mid-level moisture
available, western portions of the CWA could start seeing
precipitation as early as Saturday night.

Precipitation becomes much more widespread on Sunday with the
shortwave pushing into Wyoming by Sunday afternoon. Most locations
are likely to see some sort of precipitation, with lower elevations
seeing rain and higher elevations like the Snowy and Sierra Madres
getting accumulating snow. Temperatures on Sunday will be
fairly similar to Saturday with highs in the 40s and 50s. So
although likely not cool enough for widespread snow, a chilly,
raw day is expected. With both IVT and PWATs reaching the 90th
percentile for NAEFS climatology by Sunday, expect some decent
moisture, with QPF amounts reaching a few tenths, if not more.

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Issued at 333 PM MDT Fri Apr 24 2026

Sunday night-Monday...A series of shortwave troughs aloft move
overhead 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...Another shortwave trough aloft moves overhead, and with
adequate low and mid level moisture, we anticipate scattered to
numerous showers and a few thunderstorms. Warmer based on 700 mb
temperature trends.

Wednesday...Northwest flow aloft prevails over our forecast area.
With adequate low and mid level moisture, we anticipate scattered
showers and a few thunderstorms in the afternoon and evening.
Temperatures about the same as on Tuesday.

Thursday...A shortwave trough aloft moves across the western High
Plains states, sending a cold front across our counties, and
producing scattered showers and a few thunderstorms. Cooler
temperatures in the mid 40s to mid 50s with 700 mb temperatures near
-3 Celsius.

Friday...Weak flow aloft lies overhead and with some low and mid
level moisture, we expect scattered showers and a few thunderstorms.
Warmer temperatures as 700 mb temperatures rise to near 0 Celsius.
