NWS Pocatello, ID wrote its last area forecast discussion before the first event at Dec 9, 3:29 AM MST, 6 hours 31 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Pocatello ID 329 AM MST Tue Dec 9 2025 .KEY MESSAGES... - Above average temperatures expected throughout the week - Rain and higher elevation snow likely, with most impacts above pass level - Breezy/windy conditions will persist through at least midweek && .SHORT TERM /THROUGH TONIGHT/... Issued at 102 AM MST Tue Dec 9 2025 AR event moves through the region today from the northwest. Typically these event would produce widespread rainfall but with this one arriving from the northwest. We are seeing quite a bit of shadowing off the central mountains. For most of us that is leaving primarily wind for today. We will be near wind advisory across the Snake River Plain today with a 40 to 50 percent chance of reaching advisory levels on the sustained criteria of 25 mph. The gust criteria of 45 mph looks less likely of occurring over a widespread area. Gusts over 45 mph will likely be isolated and limited to known gusty areas such as Antelope Flats east of Idaho Falls, Botts, INL, Arco Desert, and Pocatello airport. Rain chances today are mainly limited to the mountains and highlands. The central mountains will see best rain amounts ranging from a few hundredth around Ketchum and Hailey to 0.25 to 0.50 at Stanley. The mountains west of Stanley and Galena should do well with up to 1.00 inches likely today and tonight. The eastern highlands will see rainfall amounts of 0.10 to 0.25 inches with up to 0.75 inches by Wednesday morning. Snow levels will be high, probably over 7000 feet. Several inches of snow is likely in the Sawtooths and around along the Tetons. But snow levels are too high for snow amounts to be of much impacts to our main roadways. && .LONG TERM /WEDNESDAY THROUGH MONDAY/... Issued at 1257 PM MST Mon Dec 8 2025 Extremely mild conditions is the main talking point in the long term period with temperatures ranging in the 15 to 20 degrees above normal range Wednesday through next Monday. At this point for the next 8 days there appears to be no intrusion of cold air on the horizon. Will have lingering showers Wednesday with the retreating atmospheric river conditions sliding north as upper ridge begins to build to west. Precipitation mainly limited to the Sawtooths, central mountains and eastern highlands. Snow levels between 8 and 9 thousand feet so not expecting snow impacts by Wednesday. It will be windy with 20 to 30 mph sustained winds in the Snake River Plain. Highs Wednesday mainly 40s mountains and 50s to near 60 valleys. Thursday through next Monday generally much drier with only some mountain showers with high temperatures remaining very warm with mainly 40s mountains and mid 40s to mid 50s valleys. By Friday expect to see a significant decrease in wind speeds as well. && .AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/... Issued at 329 AM MST Tue Dec 9 2025 Windy conditions are the main impact today with all sites experiencing gusts today. SUN may start with a light wind this morning, but most guidance shows a brisk west-southwest wind developing around midday. DIJ is only place where precipiation is causing restrictions to ceilings with mvfr conditions likely there today. && .PIH WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM...13 LONG TERM...GK AVIATION...13
