754 FXUS65 KPIH 250350 AFDPIH Area Forecast Discussion National Weather Service Pocatello ID 950 PM MDT Sat Oct 24 2026 .KEY MESSAGES... - Colder temperatures in place through the weekend. Sub-freezing overnight temperatures will be possible in many locations. - Dry weather through Monday. - Next system arrives Monday night into Tuesday. && .DISCUSSION... Issued at 134 PM MDT Sat Oct 24 2026 High pressure is building back into the region behind departing rain-maker. We did see areas of low clouds develop across portions of East Idaho early this morning. Where skies remained clear, temperatures were able to drop to near or below freezing. Dry and continued cool conditions will continue into Monday, though a gradual warming trend is expected for daytime highs. The next system is projected to arrive as early as Monday afternoon across portions of the central mountains, spreading east through the evening and overnight. The system speed is quick, which will limit precipitation amounts compared to the most recent systems, but the forecast amounts have increased very slightly from previous runs. This also translates to slightly increased snow potential above valley floors as temperatures drop once again with the system. We are still looking at 1-3" above 6500-7000ft, but ridgetops could see slightly higher amounts. && .AVIATION /00Z TAFS THROUGH 00Z MONDAY/... Issued at 944 PM MDT Sat Oct 24 2026 Have added wind changes for direction when it seemed consistent for a few hours. Otherwise, some morning stratus/BR continues to have a risk. NBM hourly guidance shows marginal VFR for VSBY at KBYI, and is the only place to show that. Earlier tonight, there were TEMPO periods of VSBY at IFR conditions, and a BKN layer lasted much of the day. NBM shows no CIG at KDIJ for the forecast, but have added in a BKN layer when the NAM indicates solid chances for a CIG Sun afternoon/evening. Also, for this morning, both KPIH and KIDA indicate a risk of marginal VFR for CIG at 2500ft to 3000ft AGL. && .FIRE WEATHER... Issued at 113 AM MDT Sat Oct 24 2026 Drier weather returns to the region for the weekend. Temperatures will remain slightly below normal and winds relatively light. Next system arrives Monday into Tuesday. Some breezy conditions along with wetting rain/snow above 6500 feet is a good possibility. && .PIH WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...DMH AVIATION... FIRE WEATHER...13
