The episode as NWS CYS wrote it up.
A short period of high winds occurred at the Arlington wind prone zone.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Cheyenne, WY wrote its last area forecast discussion before the first event at Nov 26, 4:28 AM MST, 2 hours 4 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Cheyenne WY 428 AM MST Wed Nov 26 2025 .KEY MESSAGES... - Marginal high winds are possible for the wind-prone areas in southeast Wyoming on Wednesday. - Colder temperatures are expected much of the week, behind a cold front that swept through the region. - The probability of an arctic cold front is increasing for next weekend which will usher in very cold temperatures and accumulating snowfall, though models continue to see notable variability. && .SHORT TERM /THROUGH THURSDAY/... Issued at 256 AM MST Wed Nov 26 2025 A chilly overnight continues early this morning with temperatures east of the Laramie Range sitting in the teens and single digits. Temperatures are bit warmer out west as breezy downslope winds contribute to temperatures in the 20s. Low temperatures will likely not get much colder as satellite imagery shows cloud cover moving into the CWA ahead of an approaching upper-level disturbance. This same disturbance will also lead to marginal high winds around the Arlington area throughout the day today. While MSLP gradients will not respond to the disturbance, CAG to CPR 700 mb gradients will become elevated. This will cause 700 mb winds to max out around 55 kts. Subsidence with this event looks decent, however the strongest subsidence does not line up with the time of strongest winds aloft. In-house guidance has also decreased high wind probabilities for Arlington and the South Laramie Range with the newest model runs. As a result, decided to hold off on any high wind headlines at this time. Will continue to monitor through the morning in case gusts start getting close to criteria, however current observations have been under 55 MPH. Besides elevated winds in the wind prones, the upper-level disturbance will increase mid-level moisture. Hi-Res guidance does show some scattered light snow showers developing during the day. If these showers do develop, they will likely cause little to no impacts as accumulation is not expected at lower elevations. A rather uneventful Thanksgiving is expected weather wise. The CWA will still be under the influence of northwest flow aloft, leading to seasonable temperatures for most cities. Hi-Res guidance does show the potential for some scattered light snow showers developing during the day due to some lingering mid-level moisture, however, global models show no precipitation due to lack of forcing. Overall, the weather will cooperate for those traveling in the CWA on Thanksgiving. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... Issued at 333 PM MST Tue Nov 25 2025 Main story in the long term remains the weekend system leading to colder temperatures and a chance of widespread snowfall for the CWA. Thursday should be mostly dry and Friday will actually be a few degrees warmer thanks to a transitory weak ridge moving across the region, with notably above normal temperatures for our area. But a deepening trough across the western US will bring an arctic airmass that will drop our highs and lows through the weekend alongside bringing a chance of precipitation for all zones. Latest runs of the NBM have dialed back our precipitation chances, and looking at ensembles it does look like the expected moisture has dropped thankfully in part to the overall trough not being quite as strong or as deep as in yesterday's runs. But there should still be enough moisture and temperatures cold enough that any precipitation that can occur will fall in the form of snowfall for all zones, and could accumulate, particularly on elevated surfaces and grassy areas for regions that have been warm or haven't seen heavy snowfall yet. The mountains should still see several inches as well, possibly prompting winter headlines though the duration will be over several days. Meanwhile the slightly weaker trough means the NBM has dialed back a small portion of the colder temperatures, but overall the spread in percentiles is still nearly similar to yesterday with Sunday being the coldest day as highs won't make it past freezing, and lows overnight into Monday morning in the very low teens to single digits. We should see temperatures warm a few degrees into Monday as the trough starts to exit, but just beyond the long term another burst of cold may be possible and our warmup should be brief. && .AVIATION /12Z TAFS THROUGH 12Z THURSDAY/... Issued at 428 AM MST Wed Nov 26 2025 Minimal aviation concerns are expected during the day at all terminals. Light winds are expected at most Nebraska panhandle terminals, however gusty winds with gusts over 30 kts will be possible at southeast Wyoming terminals during the day. Clouds will also move into the area today with the chance for a stray shower, however conditions will likely remain VFR. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...None.
