KEY MESSAGES
- LIGHT SNOW LINGERING IN THE EASTERN HIGHLANDS TODAY.
- HIGH PRESSURE BUILDS BRINGING MOSTLY DRY WEATHER NEXT WEEK.
- GRADUAL WARMING BEGINS THIS WEEKEND.
SHORT TERM /THROUGH TONIGHT/
ISSUED AT 203 AM MST FRI JAN 9 2026
A LITTLE BIT LESS ACTIVE IN THE SHORT TERM FORECAST NOW AS HIGH
PRESSURE BEGINS TO BUILD IN OVER EASTERN IDAHO TODAY. A FEW
LINGERING SNOW SHOWERS WILL CONTINUE TODAY UP IN THE MOUNTAINS
OF THE EASTERN HIGHLANDS, BUT WE'RE TALKING ABOUT 1-3 INCHES OF
SNOW ABOVE PASS LEVEL. EVERYWHERE ELSE WILL BE DRY TODAY AND IT
SHOULD BE A DRY WEEKEND, TOO. IT'S STILL A BIT BREEZY IN PARTS
OF THE SOUTH HILLS EARLY THIS MORNING WITH GUSTS AROUND 40-45
MPH STILL, BUT THOSE WILL DIMINISH THROUGHOUT TODAY. THIS WIND
HAS BEEN ENOUGH TO KEEP MUCH FOG FROM FORMING THIS MORNING, BUT
LIGHTER WINDS TONIGHT MEANS OUR CHANCES FOR FOG WILL BE
INCREASING. SO, THAT'S SOMETHING TO KEEP IN MIND IF YOU ARE
HEADING OUT LATE TONIGHT OR EARLY SATURDAY MORNING. HIGHS TODAY
REMAIN COOL, IN THE UPPER 20S TO LOW AND MID 30S, BUT LOW TO MID
30S IS RIGHT ON TARGET FOR OUR NORMAL TEMPERATURES FOR THIS
TIME OF THE YEAR. HEADING INTO TONIGHT, TEMPERATURES WILL FALL
INTO THE TEENS AND LOW 20S FOR MOST.
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 /06Z TAFS THROUGH 06Z SATURDAY/
ISSUED AT 1012 PM MST THU JAN 8 2026
THE RISK OF MARGINAL VFR HAS FALLEN OFF, WITH UNLIMITED CIG AND
VSBY AT BOTH KBYI AND KSUN, WITH PERIODS OF SKC LIKELY. SOME
AFTERNOON CUMULUS AT LOW LEVELS MAY PROVIDE MARGINAL VFR FOR
CIGS AS IT HAS CONTINUED TO BE FORECASTED AS A RISK FOR SEVERAL
HOURS. KDIJ HAS TEMPORARILY CLEARED, BUT IT APPEARS AS THOUGH
MARGINAL VFR STRATUS SHOULD RETURN AT THE COLDEST PART OF THE
DAY. AFTERNOON CUMULUS BUILD UP AT KDIJ EXPECTED TO BE HOVERING
CLOSE TO MARGINAL VFR.
WIND CONTINUES TO BE BREEZY AT KBYI FOR A FEW MORE HOURS, AND
15KT AFTERNOON WIND IS LIKELY AT KBYI, KPIH, AND KIDA. OTHERWISE
WIND SHOULD STAY BELOW 8KT.
