KEY MESSAGES

- Above average temperatures and dry conditions are expected to continue through the end of the week.

- Chances of precipitation increases over the weekend with Saturday having the best chance.

SHORT TERM /THROUGH THURSDAY NIGHT/

Issued at 202 AM MST Wed Nov 11 2026

I'm sure you heard this before, and frequently as of late, another pleasant day is on deck with plentiful sunshine and minimal cloud cover. What is going on aloft? Ridging builds back in behind the weak trough that passed through the area yesterday. This ridging will be the dominant feature in the short term period that brings us widespread benign conditions across the forecast area. Lets switch gears and take look at the most exciting thing in this forecast period, temperatures. Even though temperatures today will be slightly cooler then yesterday due to the passage of that weak system that impacted the area on Tuesday, they still will be above average on the order of 10 degrees above normal for this time of year. So, expect highs west of the Laramie Range to top out in the mid 50s. While highs along and east of the I-25 corridor will soar into the lower to mid 60s. Lows Wednesday night will bottom out generally in the low to mid 30s, with a few valleys west of I-25 seeing lows tank into the upper 20s. As we head into Thursday, look for relatively quiet conditions to continue as ridging holds firm, continuing our dry and uneventful weather. Temperatures once again will be the most exciting thing as highs will be a couple of degrees warmer, well compared to Wednesday. So, highs Thursday will generally top out in the upper 50s west of I-25 and mid 60s east of the corridor. Lows will bottom out Thursday night in the lower 30s west of the Laramie Range and low to upper 30s to the east.

LONG TERM /FRIDAY THROUGH TUESDAY/

Issued at 1240 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.

VFR conditions are anticipated through the forecast period. Weak winds tonight at terminals, at times becoming variable. KLAR and KRWL may see frost develop in the next few hours and through daybreak. Winds pick up again out of the west to northwest between 10-15 knots, gusts to 25 in the afternoon. A deck of clouds moves in from the northwest during the middle to early afternoon hours, but not much else interesting weather wise. Winds die off after sunset to become near calm at all terminals.
