DISCUSSION

Issued at 105 AM MDT Sun Oct 25 2026

Expect more dry weather today. A weak low pressure system will move into the Pacific Northwest on Monday and through the Idaho Panhandle Tuesday. This will bring rain and high elevation snow to the area late Monday, through Monday night and into Tuesday. Snow will initially fall above 8000 feet and then fall to 6500 feet Monday night. QPF with this system would range from up to 0.10 inches for the Snake River Plain and Magic Valley to up to 0.25 inches for the mountains and highlands. The official WPC forecast is around or just below the 50th percentile. There's less than a 20% chance that most of the area will be dry with just a few hundredths for the mountains and highlands and less than a 20% chance that this could be a wetter than expected system with up to 0.25 inches for the Snake River Plain and Magic Valley with 0.50 inches for the mountains and highlands. This is not going to be big snow maker central and east Idaho. The 50th percentile is for an inch or two above 6500 feet and the 90th percentile only tacks on an additional inch. Winds will increase during the day on Monday and remain gusty Monday night. Gusts of 20 to 30 mph are likely Monday afternoon. Gusts to 40 mph are likely Monday night, mainly across the Snake River Plain. Chances of reaching wind advisory criteria are less than 30%.

This system lifts away from the area Wednesday. A stray shower may be possible Wednesday. The models are showing another low pressure system moving into the Pacific Northwest late week which could result in more precipitation across the area. Temperatures are like a kiddie ride roller coaster. They will remain seasonable to start the week, cool off slightly on Tuesday, and then return to seasonable levels for mid week, but potentially falling back to slightly below normal for late week.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1023 AM MDT Sun Oct 25 2026

Pockets of stratus and fog formed this morning with clear skies and little wind. We have seen some impacts at DIJ, PIH, and BYI. While a repeat is possible tonight, percentages are overall too low to include for tonight and tomorrow morning. This likely needs re-evaluating later today. We will see an increase in mid level clouds along and east of I-15 as low pressure lifts across Wyoming, but any chance of showers is minimal at the moment. At the same time, higher level clouds will continue to increase from the west. If we happen to see fog or stratus at any particular TAF site, we will likely see a repeat of IFR to VLIFR conditions.
