816 FXUS65 KPIH 161049 AFDPIH Area Forecast Discussion National Weather Service Pocatello ID 449 AM MDT Thu Oct 16 2025 .KEY MESSAGES... - Rain and snow showers will taper off from west to east today. - Drier weather is on tap for most of southeast Idaho Friday and Saturday, before our next, faster-moving storm system moves through the region Sunday and Monday. && .SHORT TERM /THROUGH TONIGHT/... Issued at 253 AM MDT Thu Oct 16 2025 Rain and snow showers will taper off from west to east today as the responsible low pressure system pulls away from the region. Portions of the southern/eastern highlands may see another 0.10 to 0.25 inches of rain. Cooler temperatures follow tonight, with lows dropping to around freezing for many lower elevation areas. As the growing season has concluded, no further frost or freeze alerts 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 /12Z TAFS THROUGH 12Z FRIDAY/... Issued at 449 AM MDT Thu Oct 16 2025 The last organized round of shower activity associated with our now-departing storm system is becoming better organized on radar, and will impact KPIH, KIDA, and possibly KBYI this morning before pushing east. KDIJ may see showers through this evening. The main impact from this round is actually manifesting as mist and low stratus, with guidance supporting KPIH and KIDA remaining pretty socked in with predominant IFR cigs through about 19z/1pm, give or take an hour or two. KDIJ may lean more MVFR, but confidence is low on how this will evolve as showers move in...these early-cold-season moist events can be tricky. Meanwhile, skies will gradually clear and lift for KSUN (and KBYI by later this morning), with breezy southwest winds still expected up the eastern Magic Valley/Snake Plain corridor through early evening. Given all of the recent moisture and rainfall, some concern certainly exists for development of at least low stratus tonight, but so far confidence in seeing impacts at any TAF terminal is very low. && .FIRE WEATHER... Issued at 253 AM MDT Thu Oct 16 2025 Rain and snow showers will taper off from west to east today as the responsible low pressure system pulls away from the region. Expect a brief break with mostly dry conditions Friday and Saturday, before our next trough brings another round of precipitation to the region from Sunday afternoon through Monday. Winds may be a bit breezier with this next system. && .PIH WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...01 LONG TERM...McKaughan AVIATION...01 FIRE WEATHER...01
