.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 110 PM MDT Thu Mar 26 2026

A cold front has passed through the high plains of Wyoming and
the Nebraska Panhandle, ushering in a cooler airmass with higher
humidity and lighter winds this afternoon. Low clouds and
stratus has been reinforced in east central Wyoming along the
slopes of the northern Laramie range as a second wave of cold
frontal air moves southward. Low stratus has generally scattered
this afternoon over the NE panhandle, but expect the reinforcing
cold front to bring a return to low clouds over most of the high
plains near and after sunset tonight. Forecast soundings show a
potent inversion and saturated layer in the lowest few thousand
feet. However, at the surface, higher T/Td spreads will limit
the fog potential to everywhere except in the higher terrain of
the Laramie Range and perhaps the crest of the Pine Ridge.
Adjustments were made to both PoP and QPF grids this afternoon,
trending both elements downward from forecast blends. This was
supported by much lower HREF PoPs and almost negligible QPF in
model mean forecasts through the overnight into tomorrow
morning. Still, there is a chance for a few isolated sprinkles
transitioning to a rain/snow mix/all light snow overnight
through around 15z Friday morning, mainly for western Laramie
County and the eastern slopes of the Laramie Range. Given the
extremely warm temperatures recently, any snowfall will melt on
contact with road surfaces.

The other major story in the short-term is the cooler
temperatures this evening, overnight, and through the day on
Friday. Abundant cloud cover will limit solar heating, with a
deep inverted cold airmass at the surface along and east through
the high plains. While heights are expected to rise by the later
afternoon hours, the inversion will be hard to break and
temperatures will end up around or even a few degrees below
average for Cheyenne, Scottsbluff, and Sidney. Skies may begin
to clear somewhat by Friday evening, however surface
temperatures will remain chilly overnight into Saturday morning.

A rapid rebound in temperatures is on the way for Saturday as
ridging develops over the western CONUS once again. Westerly
flow and warming mid-level temperatures will result in highs
almost 20 degrees warmer on Saturday than on Friday. Expect a
few afternoon clouds to drift in from the west as a bit of mid-
level moisture moves in over top of the ridge. A few isolated,
very high-based showers will be possible on Saturday evening
given highs reaching convective temps and the slight increase in
moisture in the 700-300mb layer.

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 110 PM MDT Thu Mar 26 2026

Sunday-Monday...Continued mild as the flow aloft remains from the
west. With some low and mid level moisture, we may see isolated to
widely scattered late day showers on Monday.

Tuesday...As a shortwave trough aloft and its associated cold front
pass by the forecast area, high temperatures will decrease into the
60s. Looks like enough low and mid level moisture to produce
scattered showers, most numerous near the Colorado state line.

Wednesday...Even cooler in the wake of the Canadian origin cold
front. 700 mb temperatures near 1 Celsius will yield maximum
temperatures in the 50s. With broad troughiness across the forecast
area and increasing low and mid level moisture, we will see
scattered to numerous showers develop.

Thursday...In this progressive pattern, another shortwave trough
aloft will move overhead and will combine with adequate low and mid
level moisture to produce scattered to numerous showers.
