UPDATE
ISSUED AT 435 PM MST THU JAN 8 2026
WIND ADVISORY WAS ALLOWED TO EXPIRE AS WIND HAS FALLEN BELOW
THRESHOLDS.
SHORT TERM /THROUGH FRIDAY NIGHT/
ISSUED AT 1144 AM MST THU JAN 8 2026
WE CONTINUE TO WATCH SNOW SHIFTING ACROSS THE I-15 CORRIDOR AND
INTO THE EASTERN AND SOUTHEAST HIGHLANDS THIS AFTERNOON. FOR THE
REST OF TODAY AND TOMORROW, A FEW SNOW SHOWERS ARE EXPECTED
ACROSS PORTIONS OF THE CENTRAL MOUNTAINS, EASTERN AND SOUTHEAST
HIGHLANDS. THERE COULD BE A COUPLE OF SHORT PERIODS WHERE WE
GET LIGHT UPSLOPE SNOW FROM POCATELLO THROUGH REXBURG, BUT THAT
MAY END UP BEING NOTHING MORE THAN SOME FLURRIES. WE DO HAVE
SOME WIND OUT THERE, BUT THAT CONTINUES TO DECREASE INTO THIS
EVENING. THE STRONGEST WILL REMAIN ACROSS PORTIONS OF THE MAGIC
VALLEY SOUTH INTO THE SOUTH HILLS AND ALBION MOUNTAINS. WE WILL
KEEP THE WIND ADVISORY OUT THROUGH LATE AFTERNOON. ELSEWHERE,
THE WIND HAS BEEN STRONG ENOUGH TO CREATE SOME SLICK SPOTS AND
BLOWING/DRIFTING CONDITIONS. THERE WILL BE SOME LINGER POCKETS
OF STRONGER GUSTS TONIGHT AND FRIDAY, BUT NOTHING TOO STRONG. IT
STILL MIGHT BE ENOUGH THOUGH FOR LIMITED BLOWING AND DRIFTING
SNOW. THE POTENTIAL OF FOG IS THERE, ALTHOUGH THE BLEND OF
MODELS REALLY HAS NOTHING FOR TONIGHT AND A BETTER POTENTIAL
TOMORROW NIGHT. WE DID GO AHEAD AND INCLUDE PATCHY FOG ACROSS
MOST OF THE SNAKE PLAIN AND MAGIC VALLEY AND TOWARD MONIDA PASS
AND ISLAND PARK TONIGHT. WE HAVE MORE WIDESPREAD FOG TOMORROW
NIGHT WHICH INCLUDES THE TETON VALLEY AND OTHER VALLEYS ACROSS
THE EASTERN AND SOUTHEAST HIGHLANDS. WE ALSO SUSPECT THERE
COULD BE SOME FOG IN THE STANLEY BASIN BOTH NIGHTS, AND WENT
AHEAD WITH INCLUDING THAT IN THE FORECAST. IT MAY END UP THAT
THERE IS TOO MUCH MIXING OUT THERE TO ALLOW ANYTHING TO FORM,
AND LIGHTER WINDS TOMORROW NIGHT ARE MORE FAVORABLE FOR THAT TO
OCCUR.
LONG TERM /SATURDAY THROUGH THURSDAY/
ISSUED AT 1144 AM MST THU JAN 8 2026
DRY AND MORE TRANQUIL CONDITIONS ARE EXPECTED FOR THE WEEKEND AND
INTO EARLY NEXT WEEK AS A RIDGE OF HIGH PRESSURE BUILDS OVER THE
REGION. THIS SHOULD LEAD TO QUIET WEATHER ACROSS EASTERN IDAHO WITH
THE ONLY CONCERN BEING THE POTENTIAL FOR SOME VALLEY INVERSIONS AND
MAYBE SOME PATCHY FOG IN AREAS WITH SNOWPACK AND/OR MELTING SNOW
KEEPING THE LOWER LEVELS MOIST. TEMPERATURES WILL MODERATE GRADUALLY
THROUGH MID-WEEK WITH MOSTLY DRY WEATHER PREVAILING, THROUGH SOME
OCCASIONAL PRECIP CHANCES APPEAR POSSIBLE MAINLY ALONG THE DIVIDE
AND OVER TOWARDS ISLAND PARK AS SOME LIMITED MOISTURE MAY BE ABLE TO
MOVE ON THE NORTHERN PERIPHERY OF THE RIDGE. MOST OF THE MOISTURE
LOOKS TO STAY NORTH OF THE REGION HOWEVER BASED ON RECENT MODEL
TRENDS SO THESE POP CHANCES WOULD BE RATHER LOW. TEMPERATURES WILL
REMAIN ON THE WARM SIDE OF NORMAL THROUGH THE PERIOD, BY AROUND 5
DEGREES FOR THE WEEKEND, BUT WARM CLOSER TO 10 DEGREES ABOVE NORMAL
BY THE MIDDLE OF NEXT WEEK AS THIS GENERALLY MILD WINTER CONTINUES
ACROSS EASTERN IDAHO.
AVIATION /00Z TAFS THROUGH 00Z SATURDAY/
ISSUED AT 435 PM MST THU JAN 8 2026
WIND HAS SUBSIDED AND SHOWERS ARE NEARLY DONE, WITH PERHAPS
ANOTHER 2 HOURS IN THE EASTERN TWO AIRDROMES, KIDA AND KDIJ.
WIND WILL SUBSIDE EVERYWHERE BUT KBYI, WHICH WILL ACTUALLY HELP
KBYI STAY VFR IN THE MORNING. NORTHWEST WIND WILL KEEP KSUN WITH
UNLIMITED CIG AND VSBY. THE DICEY TERMINALS WILL BE KIDA AND
KPIH, WHERE BR/FG IS NOW A THREAT WITH SKIES CLEARING ALOFT AND
PLENTY OF MOISTURE ON THE GROUND TO EVAPORATE THEN COOL,
ESPECIALLY WITH LIGHT WIND. THE NBM GUIDANCE ALSO WANTS TO
DEVELOP STRATUS IN THE AFTERNOON FOR BOTH KIDA AND KPIH,
HOWEVER, MORE USUAL IS MORNING STRATUS BEING EVAPORATED AND HAVE
GONE WITH THAT, BUT ONLY TO MARGINAL VRF CONDITIONS FOR CIGS.
FINALLY KDIJ, MARGINAL VFR CONDITIONS DUE TO CIG SHOULD CONTINUE
ON AND OFF, WITH BOTH THE AVAILABLE DETERMINISTIC AND NBM
GUIDANCE INDICATING AFTERNOON STRATUS HERE.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
