Area Forecast Discussion National Weather Service Cheyenne WY 1035 PM MST Sun Dec 14 2025 .KEY MESSAGES... - Arctic cold front will linger across the eastern plains Sunday with cold temperatures and some patchy freezing fog across western Nebraska. - Warming trend expected later today through early next week with strong winds returning to southeast Wyoming Tuesday through Thursday. - Next chance for precipitation on Wednesday with periods of snow and rain possible. && .SHORT TERM /THROUGH MONDAY NIGHT/... Issued at 1258 PM MST Sun Dec 14 2025 Mild and generally tranquil weather will continue over southeast Wyoming and western Nebraska throughout the short-term period. A sprawling ridge of high pressure continues to dominate the synoptic weather pattern over the southwestern CONUS, directing the jet stream and related storm track far into the Pacific Northwest and Canadian maritime. As heights have continued to build over the past day or so, tighter gradients have also retreated to the north, resulting in far lower wind speeds over the Wyoming high country. Light westerly flow today around the top of the ridge will result in another day of record-high temperatures, with Cheyenne already breaking their high temperature as of 1pm this afternoon. High cirrus clouds will drift eastward this evening with a mostly clear overnight expected. Short-term ensemble guidance remains in excellent agreement showing a gradual breakdown in ridging over the region on Monday through Tuesday. As this occurs, height gradients will increase along with a modest increase in westerly flow along the top of the ridge axis. These two elements will combine to increase surface wind speeds across the typical wind-prone corridors of southeast Wyoming on Monday and into Tuesday. In-house guidance does show the potential for high-wind criteria exceedance in the Snowy Range foothills by Monday night, however recent runs have somewhat delayed the start of this high wind event. Therefore, we will opt to hold off on any watch products at this time. Despite slightly lower heights, faster westerly flow will increase downsloping effects and afternoon high temperatures will continue to run near record high values early this week. Overall forecast confidence is very high with regard to the temperature forecast and moderate with the wind speed forecast given some uncertainty in high-wind ramp-up timing. && .LONG TERM /TUESDAY THROUGH SUNDAY/... Issued at 1258 PM MST Sun Dec 14 2025 With a generally low amplitude upper air pattern through the next week there is good synoptic agreement upon how the pattern unfolds. Beyond the Monday night clipper to the north along the international border will be a stronger wave come Wednesday that dives a bit further south into the northern tier US states with subtle timing and strength differences among global ensembles. The GEFS and Euro ensembles show good agreement on track and timing of the wave but disagree slightly on the amplitude. Whereas the GEFS and Canadian ensembles agree better on the amplitude of the wave as it passes to our north but show subtle timing differences with the GEFS being slightly slower in its progression. Now what do these differences mean in terms of impacts for the forecast area? Probably just differences in when the wind shuts off after it begins. Ensemble members show decent agreement with regards to the strength of 700mb flow Tuesday morning through Wednesday morning ahead of the wave as the 25th to 75th range is roughly 40-50kts meaning this early week period likely stays confined to the wind prones for high winds with in-house guidance supporting this. Looking at Wed AM through Thur AM we see 700mb flow ticks up over 60kts with some members showing as high as 70kts or more (low confidence on that). This will likely bring more widespread high winds to the region with available guidance showing this to be a more widespread event likely bleeding outside the wind prones and into the adjacent high plains. This Wednesday event looks to be a quick hitter and not long lasting thankfully (<24 hours). The pressure gradient then looks to reverse for Thursday (once winds die down on which timing is still low confidence) shutting off the wind machine for a short time before another surge in winds aloft brings flow equal to if not slightly stronger than the Wednesday event. This would begin late Thursday lasting well into Friday and possibly early Saturday. Flow then looks to turn more zonal with lesser chances for shortwave activity to bring impactful winds the region. Along with the winds should come some light shots of moisture Wed/Thur and again next weekend. This would be most impactful for the high terrain (above 8000ft) where a few inches of snow would be expected though can't rule out a few hundredths of rain or a dusting of snow in the low elevations. Looking at temps quickly we are quite a bit above average (37-42F along east of I25) with highs likely to reach well into the 50s for areas below 7000ft Wednesday and then Friday through the weekend. Thursday will be slightly cooler in the 40s behind a cold front. Low to mid 60s even appear probable Wednesday and Friday with high temperature records very much in danger for most locations on Friday. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1035 PM MST Sun Dec 14 2025 Quiet conditions with relatively light winds and clear skies continue through Monday, before winds increase over the southeast Wyoming terminals Monday night.
