.KEY MESSAGES...
- Mild to warm temperatures will continue through Friday, before
  a potent weather disturbance aloft and its associated cold
  front bring cooler and wetter weather for the weekend.
&&
.SHORT TERM /THROUGH SATURDAY/...
Issued at 316 AM MDT Thu Oct 2 2025
Today...A warming trend develops again as the flow aloft turns
southwest, with 700 mb temperatures near 10 Celsius yielding maximum
temperatures in the mid 70s west of I-25, with mainly 80s east of
I-25.
Friday...Southwest flow aloft strengthens in advance of the potent
shortwave trough aloft over eastern Utah. With a slight increase in
700 mb temperatures, highs will be slightly warmer. Looks like
adequate low and mid level moisture to spark isolated to widely
scattered evening showers and thunderstorms over Carbon County.
Saturday...The progressive shortwave trough aloft moves to eastern
Wyoming in the afternoon, producing scattered to numerous showers
and scattered thunderstorms, in addition to cooler temperatures in
the wake of a cold frontal passage. Low and mid level gradients
suggest a windy day for much of the forecast area.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Issued at 316 AM MDT Thu Oct 2 2025
Sunday...Strong southwest flow aloft prevails over cool surface high
pressure producing low level upslope and extensive cloud cover. 700
mb temperatures near -2 Celsius will yield cool daytime high
temperatures from the lower 50s to lower 60s. The lift produced by
low level upslope and a weather disturbance aloft will help generate
scattered showers and isolated thunderstorms in the afternoon and
evening.
Monday...Cool surface high pressure across the western high plains
will help keep cool low level upslope in place with maximum
temperatures only in the 50s. Adequate low and mid level moisture
will help produce isolated to widely scattered afternoon and evening
showers.
Tuesday...Weak ridging aloft develops. Expect a slow warming trend
as the airmass moderates somewhat, though surface high pressure over
the Northern High Plains states will keep cool air over our
counties. With the lack of a lifting mechanism, showers will remain
isolated in the afternoon and evening.
Wednesday...With ridging increasing aloft, and 700 mb temperatures
rising to near 6 Celsius, high temperatures will continue to rise
into the mid 60s to near 70 degrees. Adequate low and mid level
moisture for isolated late day showers and thunderstorms.

VFR conditions are expected through the TAF period with mostly clear
skies expected across the area. Breezy conditions are expected at a
few terminals this afternoon with gusts to 25 kts possible. Later
this evening a low-level jet will develop over western Nebraska,
potentially leading to gusty winds overnight at Nebraska panhandle
terminals.
