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 /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1055 AM MDT Sat Oct 24 2026

Conditions continue to slowly improve across eastern Idaho, although it appears SUN and DIJ will be the last to see solid MVFR/IFR conditions burn off. The Blend of Models and other cross sections show low to mid level moisture hanging around, so we are hesitant to lose any of those ceilings altogether. Therefore, we kept few to scattered MVFR/IFR ceiling levels in the TAFs but nothing going back to broken or overcast. We've also kept fog out of the forecasts. We have seen quite a bit of moisture in the past 24+ hours, but the only site that had fog this morning was DIJ. None of the data shows fog returning tonight, with might be a bit suspect given the precipitation that occurred. We may have to rethink the potential for more solid MVFR/IFR conditions overnight and tomorrow morning for later TAF issuances.

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.
