DISCUSSION

Issued at 1231 PM MST Tue Nov 3 2026

Currently there is weak high pressure over our area with clouds starting to move over our area in southwest flow from an upper level low located currently over northern California.

Models show the low over northern California weakening and moving over central Utah giving our southern areas a slight chance of showers later Wednesday. Little, if any, precipitation is currently expected. Temperatures Wednesday warm slightly compared to Tuesday with highs in the mid 40s to mid 50s.

By Thursday, an upper level low will move over northern Idaho. Expect slightly breezy winds and just a slight chance of precipitation, especially across the Wyoming border. Temperatures drop slightly Thursday with temperatures in the low 40s to low 50s.

Expect patchy fog Wednesday morning and, especially, Thursday and Friday mornings, particularly near water sources.

Expect a warm up Friday into Saturday under high pressure. Look for Saturday high temperatures in the low 50s and low 60s.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 1056 AM MST Tue Nov 3 2026

VFR conditions prevailing this morning across all eastern Idaho terminals. Winds are expected to generally be light through the forecast period. Biggest impact to aviation will be increasing CIGs over the next few hours as an upper low swings across the northern edge of the Great Basin. Doesn't look like there will be much, if any, moisture with these feature but it will increase mid/high level clouds across the area leading to SCT- OVC CIGs into the first part of the day tomorrow. Cloud bases should remain high enough to keep VFR in place however.

FIRE WEATHER

Issued at 123 AM MST Tue Nov 3 2026

This will be the last discussion as Fire Season in Idaho has ended for 2026 after two record-setting precipitation events within two weeks of each other. Cool temperatures continue, staying at or below 50 degrees F. Humidity at this temperature will easily stay above 40 percent even in the afternoon. Temperatures will warm up starting Sun, but only to around the 60 degree mark. There will be a low moving through UT on Wed that will bring a slight chance threat to southern portions of the Fire Weather District on Wed. A trough will move through the Idaho panhandle and western Montana Thu/Thu night to produce another slight chance threat of precipitation, but all of these events bring very little in the way of wind. Just expect normal gusty afternoons if the skies are clear, such as today and Fri.
