KEY MESSAGES

- Near to just above average temperatures and mostly dry conditions are expected today into and through the weekend.

SHORT TERM /THROUGH SATURDAY NIGHT/

Issued at 202 AM MST Fri Nov 6 2026

Currently, Nighttime Microphysics satellite imagery shows that we have mid to high-level clouds beginning to move into the forecast area. This is ahead of a weak shortwave trough sliding across the region. In place, east of the shortwave over portions of the CWA we have a ridge aloft nosing up into the area pumping in southwesterly winds aloft. This will aid high temperatures to climb back into the mid 40s to around 50 west of the Laramie Range and mid to upper 50s to the east for this afternoon. Shifting gears back to the shortwave, throughout the day this will slide across the forecast area, as it does so, it will promote a wind shift aloft to become more northerly. Most of the area will remain dry with this system; however, a few of the higher peaks may see some precipitation, albeit a very slight chance. As we progress into the afternoon hours, as this shortwave passes, clouds should begin to thin and break up, with skies becoming mainly clear. These clear skies for tonight will help temperatures dip into the upper 20s to low 30s across the CWA. Due to this radiational cooling, it is not out of the realm of possibility to see a few of the colder spots dip below forecasted lows, like into the lower 20s. By Saturday, ridging aloft will reestablish itself across the forecast area, keeping us dry while lower-level winds become westerly. This will promote favorable downsloping winds and thus making temperatures a tad bit warmer then today. Expect highs to top in the upper 40s to low 50s west of the I-25 and upper 50s to low 60s east of the corridor. While overnight lows Saturday night will only dip into the low to mid 30s.

LONG TERM /SUNDAY THROUGH THURSDAY/

Issued at 130 PM MST Wed Nov 4 2026

No major changes in the long term, except for taking out Saturday and starting the long term discussion on Sunday, please see previous discussion below...

Sunday...Well pronounced ridging aloft continues, keeping us mild and dry. 700 mb temperatures near 6 Celsius will yield maximum temperatures from the upper 50s to upper 60s.

Monday-Tuesday...Dry and mild weather will continue with westerly flow aloft and only a weak positively tilted shortwave trough aloft moving across Wyoming on Tuesday.

Wednesday-Thursday...Ridging aloft reasserts itself across the Great Basin States from western Montana to Utah, keeping our counties in northerly flow aloft. 700 mb temperatures from 0 to 2 Celsius will help produce high temperatures from the mid 50s to mid 60s.

AVIATION /12Z TAFS THROUGH 12Z SATURDAY/

Issued at 424 AM MST Fri Nov 6 2026

VFR conditions will prevail across all terminals for the duration of this TAF period. Mid to high-level clouds are rolling through due to a shortwave approaching the CWA, these clouds will pose no aviation threat, and will clear up later this afternoon. While winds will remain relatively light, generally less than 10 knots across all sites.

CYS WATCHES/WARNINGS/ADVISORIES

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