621 FXUS65 KPIH 160012 AFDPIH Area Forecast Discussion National Weather Service Pocatello ID 612 PM MDT Wed Oct 15 2025 .KEY MESSAGES... - Widespread showers with a few thunderstorms today, lingering into Thursday especially along and east of Interstate 15. - Nearly all snow accumulation will remain above about 7,000 feet, with limited travel impacts possible at a few passes. - Drier weather for most of southeast Idaho Friday and Saturday. && .SHORT TERM /THROUGH THURSDAY NIGHT/... Issued at 134 PM MDT Wed Oct 15 2025 Amplified trough remains in place over the Intermountain West today with closed low centered over southern NV/UT, per satellite imagery. Radar indicates widespread rainfall, some moderate to locally heavy with a few embedded thunderstorms working north through the region. Snow levels remain above 7000 ft, with a few impacts remaining possible at pass level. Upper trough slowly transitions east through tonight, bringing upper flow around to the north, essentially rotating the bands of showers back through the region. Snow totals through tonight have moderated slightly with the most recent model data, but high end probabilistic amounts still reach 6-10" above pass level. Precipitation shifts to the eastern half of the forecast area during the day Thursday, with the persistent showers coming to an end during the evening. Cooler temperatures follow Thursday night, with lows dropping to around freezing for many lower elevation areas. As the growing season has concluded, no further Frost or Freeze headlines will be issued until Spring. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... Issued at 134 PM MDT Wed Oct 15 2025 Friday will feature conditions gradually improving across the area as high pressure once again builds over the region, albeit briefly. Will likely see some lingering clouds for the first part of the day along with maybe some isolated/scattered precip chances in the eastern highlands during the afternoon and evening hours; otherwise, most of the region should be dry. Dry weather will continue into Saturday regionwide with temperatures remaining on the cooler side of normal. Sunday looks to be the warmest day in the extended with 60s likely in the lower elevations as winds increase out of the S/SW ahead of an approaching upper level trough that will swing through the region during the overnight and into the first part of the day on Monday. When this happens, expect clouds and precip chances to increase across the area Sunday evening and for a good part of the day on Monday with MUCH cooler temps looking increasingly likely for the day on Monday. Highs look likely to only top out in the 40s on Monday throughout the area with widespread cloud cover and precip in the forecast. Once again, expect some high elevation snow with this feature, likely above 6000 ft. This system is forecast to be a quick mover however and will likely be well east of the area by daybreak Tuesday. The upper flow will remain out of the NW though which will keep cooler air in place Tuesday and into Wednesday, about 5-10 degrees below normal, but those days do appear that they`ll be dry at the present time. && .AVIATION /00Z TAFS THROUGH 00Z FRIDAY/... Issued at 605 PM MDT Wed Oct 15 2025 Expect continued showers and MVFR to near MVFR conditions for all TAF sites overnight. Brief IFR conditions are possible with heavier showers. KIDA and KDIJ still have a chance of VCTS for the next couple of hours with a stronger wave approaching from the south. Otherwise, expect light showers off and on overnight with MVFR conditions when showers are on station for TAF sites tonight. Winds pick up with gusts of around 20 mph for most sites by tomorrow late morning to early afternoon. Expect VFR conditions overnight for KSUN and by mid to late tomorrow morning for KBYI. KIDA and KPIH will become VFR by early to mid afternoon tomorrow. KDIJ will take a little longer for VFR conditions, late afternoon to early evening tomorrow. && .FIRE WEATHER... Issued at 151 AM MDT Wed Oct 15 2025 Periods of wetting rains and high-elevation snow will continue today and tonight, lingering Thursday especially along and east of Interstate 15 (but overall ending from west to east over the course of the day). Drier conditions will briefly take hold for Friday and Saturday. && .PIH WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...DMH LONG TERM...McKaughan AVIATION...TW FIRE WEATHER...01
