KEY MESSAGES

- Windy conditions are expected today alongside elevated fire weather concerns.

- Above average temperatures and dry conditions are expected to continue into and through the end of the week with our first chance of even meager precipitation expected on Saturday.

SHORT TERM /THROUGH THURSDAY NIGHT/

Issued at 1238 PM MST Tue Nov 10 2026

Conditions remain benign in the short term forecast period as we see temperatures remain around 10 to 15 degrees above normal with minimal impacts expected. The most noteworthy feature of the forecast period is occurring today as a modest jet is seen over the area in relation to a dry trough moving across. Some breezy winds have been noted, the strongest of which across the I-25 corridor up through the Bordeaux area, but sensors utilized in the region are not reporting so it's hard to say to what extent the strongest conditions are, but a few gusts nearing 60 mph can't be ruled out in this corridor. The jet should continue to bring enhanced conditions through the evening hours before weakening thereafter. Otherwise temperatures remain on the warm side today with widespread highs in the 50's west of the Laramie Range, and 60's to near 70 to the east.

Into Wednesday temperatures will cool down slightly due to the system that just passed through the region, but don't expect a dramatic drop in highs. Widespread temperatures stay in the mid 50's to mid 60's as ridging begins to move back in and resume control of the region. We'll continue our dry and uneventful spell under this feature, with temperatures then warming a couple of degrees on Thursday.

LONG TERM /FRIDAY THROUGH MONDAY/

Issued at 1238 PM MST Tue Nov 10 2026

Friday...The high amplitude ridge axis aloft moves from western Wyoming to western Nebraska by evening, with subsidence and dry air continuing the dry and mild trends. 700 mb temperatures near 5 Celsius will yield high temperatures from the mid 50s to mid 60s.

Saturday...The flow aloft turns southerly with falling heights as the next trough aloft approaches from the Great Basin states. Looks like adequate low and mid level moisture to produce scattered dynamic and orographic showers across our Snowy and Sierra Madre Ranges, with dry conditions elsewhere. Cooler temperatures with more opaque cloud cover overhead.

Sunday...The trough aloft opens up and moves into the Texas Panhandle by late in the day, with only some residual cloud cover, and no precipitation left over in our forecast area.

Monday...Another transitory ridge aloft moves overhead, keeping our weather dry and mild, with 700 mb temperatures trends suggesting slightly warmer surface temperatures.

Tuesday...The flow aloft backs to south southwesterly in advance of the next approaching shortwave trough aloft. Looks like enough low and mid level moisture for scattered rain and snow showers over much of Carbon County, including the Sierra Madre Range, with dry conditions elsewhere. Temperatures slightly cooler with additional cloud cover compared to Monday.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 1029 AM MST Tue Nov 10 2026

Brisk northwest flow aloft will continue, with a fast moving weather disturbance sweeping across the region this afternoon, but with only some mid and high level cloudiness.

High confidence in VFR prevailing. Expect scattered to broken clouds near 15000 feet. Winds will gust to 35 knots through early this evening due to surface pressure gradients, with wind gusts to 22 knots at KCYS from 02Z to 15Z.

CYS WATCHES/WARNINGS/ADVISORIES

WY...None. NE...None.
