050 FXUS65 KCYS 090602 CCA AFDCYS Area Forecast Discussion...Corrected National Weather Service Cheyenne WY 1100 PM MST Sat Nov 8 2025 .KEY MESSAGES... - Very windy conditions across the Nebraska Panhandle Saturday with gusts over 50 MPH possible Saturday afternoon. - Generally dry and quiet weather expected for much of next week. Locally strong winds expected for the southeast Wyoming wind prone areas late Monday and into Tuesday. && .SHORT TERM /THROUGH SUNDAY NIGHT/... Issued at 251 PM MST Sat Nov 8 2025 Strong northwest winds continue this afternoon across the eastern portion of the CWA. Current observations show gusts in excess of 50 MPH in parts of the Nebraska panhandle. The upper-level pattern lends itself to these strong winds as the region is sandwiched between a ridge to the west and a trough to the east. This positions a strong 250 mb jet over the CWA, leading to the elevated winds. The jet is slow to move out so gustiness is expected to continue into the evening hours before weakening overnight. Cold air will stay locked in place on Sunday as chilly northwest flow continues to dominate. Sunday morning lows will only be in the teens and 20s as mostly clear skies allow for effective radiational cooling overnight. 700 mb temperatures will remain below 0C during the day, so highs will struggle to even reach average for mid- November. Afternoon temperatures will be in the 40s for most cities. Luckily, winds will be much weaker Sunday and will not add to the coolness. The approaching ridge from the west will keep skies mostly sunny throughout the day with no chance for precipitation. && .LONG TERM /MONDAY THROUGH SATURDAY/... Issued at 251 PM MST Sat Nov 8 2025 Temperatures rebound nicely after a cool weekend with highs soaring back into the mid 50s to mid 60s, warmest across eastern Wyoming and the Nebraska Panhandle. Lows will dip into the low 30s to low 40s, expect these temps to hold firm through most of the long term period. All this is due to an upper level pattern change with ridging nosing back into the region as a deep low shifts off to the east. As we progress in the long term, with ridging building in, weather conditions will remain relatively benign with precipitation chances near nil across the CWA through the long term period. One thing that we are watching is the possibility of another high wind event, west of I-25, for our typical wind prone areas Monday into Tuesday along portions of I-80 and I-25. The latest guidance continues to show good support at 700mb and the surface for this to pan out. Winds will begin to ramp up Monday morning and be at threshold somewhere around Monday afternoon (00z Tuesday). So, stay tuned for updates as High Wind products may be issued in the very near future. At the tail end of the long term, models are suggesting a deep trough moving into and across the Intermountain West Friday and into our CWA by Saturday morning. If this stays on track, precipitation chances will increase along with another drop in temperatures, essentially bringing in a pattern change. && .AVIATION /06Z TAFS THROUGH 06Z MONDAY/... Issued at 1100 PM MST Sat Nov 8 2025 North to northwest flow aloft will continue into Sunday. Primary Aviation concern will be low CIGS across portions of the northern and central Nebraska Panhandle tonight through 16z Sunday morning. HAZARDS/WEATHER TRENDS: VFR conditions will prevail at all southeast Wyoming terminals over the next 24 hours. Low MVFR CIGS will continue at KCDR and KAIA and may even approach KSNY by sunrise Sunday. Can`t rule out these 1100 to 1500 ft CIGS dipping below 1000 feet at times, but confidence is limited and generally below 40% chance. Low CIGS are not expected to lift until 18z Sunday. Winds will be lighter today with a few gusts up to 25 knots possible across western Nebraska. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...None. NE...None. && $$ SHORT TERM...SF LONG TERM...RZ AVIATION...TJT
