FXUS65 KCYS 032225 AFDCYS Area Forecast Discussion National Weather Service Cheyenne WY 325 PM MST Tue Feb 3 2026 .KEY MESSAGES... - Banding rain/snow/mixed precipitation is expected through the evening across the region, with low amounts generally from a trace to a dusting expected, though higher amounts could occur under sustained bands. - Dry weather and mild temperatures expected for the rest of the week and into the weekend. Possible change in the weather pattern early next week. && .SHORT TERM /THROUGH WEDNESDAY NIGHT/... Issued at 324 PM MST Tue Feb 3 2026 As of this writing, we've seen some graupel coming down at the office here in Cheyenne. Mesoanalysis indicates around 100 J/kg of MUCAPE across the region, fueling the potential to form banding precipitation, and this has been seen on radar. With low PWAT values present, getting much more than a trace to a dusting is not expected, but not impossible either. Anywhere that does see a stronger band or two develop could exceed a half inch to inch of snow, but temperatures are going to have to fall a few more degrees at least before we start to see anything more noteworthy in the realm of snow (most locations are seeing temperatures in the 40's to near 50 in Chadron). With the semi-dry conditions present, overall expectations are that it's going to have to be an impressive feature to notably accumulate, otherwise most locations will forget they even got precipitation after it's over. Overnight into Wednesday morning precipitation will clear out, and then high pressure ridging will take over, bringing us calm and benign weather moving into the long term. Highs will rise tomorrow into the the 50's, a prelude for even warmer conditions to come to end the week. Otherwise with no features promoting more significant weather, look for mostly light winds, a few clouds in the sky, and no precipitation to speak of. && .LONG TERM /THURSDAY THROUGH MONDAY/... Issued at 324 PM MST Tue Feb 3 2026 The long term remains mostly on track, characterized by remarkably benign weather. A persistent upper-level ridge over the western half of the country will lead to dry and mild weather across the CWA. Precipitation chances will be nearly non-existent Thursday through the end of the week and into the weekend as subsidence under the ridge keeps condiitons dry. Dry air aloft will also aid in mostly sunny skies throughout this time period. Well above average temperatures are also expected to persist across the forecast area during this time period. 700 mb temperatures will be in the 90th percentile and above according to NAEFS climatology. This will lead to high temperatures about 20 degrees above average across the CWA. Highs for most locations will be in the 50s and 60s, leading to pleasant, but far from seasonal conditions. Several high temperatures records will likely be tied or broken between Thursday and Sunday. Besides record warmth, brief elevated to high winds could be possible in the usual southeast Wyoming wind prones Saturday morning and again on Sunday night thanks to a few weak systems moving across the area. In-house guidance is still only showing elevated winds at this time due to increased MSLP gradients across the Laramie Range. Models hint at the potential for precipitation returning to the CWA next week. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1049 AM MST Tue Feb 3 2026 Mid to low-level clouds will persist at most terminals throughout the day as a cold front moves across the area. Precipitation will be possible with the front in terms of both rain and snow, with rain more likely during the afternoon and snow expected in the evening. Visibility reductions are expected, especially in light to moderate snow showers. IFR visibilities cannot be ruled out. Low CIGs will also be possible throughout the afternoon and overnight with the increased moisture behind the front. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...None.
