AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
435 AM MST SAT JAN 10 2026
KEY MESSAGES
- HIGH PRESSURE CONTINUES TO BRING MOSTLY DRY WEATHER INTO NEXT
WEEK.
- GRADUAL WARMING BEGINS THIS WEEKEND.
- PATCHY DENSE FOG POTENTIAL EARLY THIS MORNING AND AGAIN
TONIGHT.
SHORT TERM /THROUGH TONIGHT/
ISSUED AT 155 AM MST SAT JAN 10 2026
HIGH PRESSURE OVER THE SOUTHWESTERN US MAKES FOR SOME RELATIVELY
QUIET WEATHER AFTER AN ACTIVE WEEK. THE RIDGE AXIS WILL MOVE
DIRECTLY OVER EASTERN IDAHO TODAY AND DRY CONDITIONS ARE STILL
EXPECTED, THOUGH WE HAVE SEEN SOME LIGHT SEEDER-FEEDER SNOW UP IN
THE ISLAND PARK TO DRIGGS AREA AS UPPER LEVEL CLOUDS ARE MOVING OVER
THIS MORNING'S LOW STRATUS IN THE SAME AREA. THOSE LOW CLOUDS REMAIN
OVER A GOOD PORTION OF THE SOUTH HILLS, EASTERN HIGHLANDS, AND UPPER
SNAKE RIVER PLAIN. SO FAR, THE WIND SEEMS TO BE STRONG ENOUGH TO
KEEP IT ELEVATED ENOUGH TO KEEP THESE CLOUDS AS LOW STRATUS.
MORE LOW STRATUS HAS BEEN DEVELOPING OUT ACROSS THE INL/ARCO
DESERT, SO THAT IS ANOTHER AREA WE WILL CONTINUE TO WATCH. THIS
AFTERNOON, HIGHS WILL WARM INTO THE 30S FOR MANY WITH PARTS OF
THE EASTERN MAGIC VALLEY AND SOUTH HILLS COMING CLOSE TO
REACHING THE 40 DEGREE MARK. THIS SHOULD FINALLY ALLOW FOR A BIT
OF MELTING TO THE SNOW THAT FELL (FOR SOME OF US) THE OTHER
NIGHT AND THAT IN ADDITION TO DIMINISHING WINDS WILL MAKE FOR
SOME PATCHY DENSE FOG ONCE AGAIN TONIGHT INTO SUNDAY MORNING.
LONG TERM /SUNDAY THROUGH FRIDAY/
ISSUED AT 147 PM MST FRI JAN 9 2026
THE EXTENDED TIMEFRAME WILL BE FAIRLY UNEVENTFUL, WITH DRY AND
WARMER THAN AVERAGE CONDITIONS. THE SOLE CONCERN WILL BE THE
POTENTIAL FOR FOG DURING THE OVERNIGHT AND EARLY MORNING HOURS.
OTHERWISE, CONDITIONS WILL REMAIN DRY AND WINDS LIGHT UNDER HIGH
PRESSURE. DAYTIME TEMPERATURES WILL SPAN THE 30S AND 40S, WARMING TO
5 TO 10 DEGREES ABOVE NORMAL FOR THIS TIME OF YEAR. THE NEXT
POTENTIAL CHANCE FOR ANY PRECIPITATION WILL BE THURSDAY EVENING, AT
THE EARLIEST. APPROXIMATELY 40 PERCENT OF TOTAL ENSEMBLE CLUSTER
MEMBERS SUGGEST A BREAKDOWN OF THE UPPER LEVEL RIDGE COME LATE NEXT
WEEK/WEEKEND, HOWEVER, OVER HALF THE MEMBERS FAVOR A PERSISTENT
RIDGE THROUGH AT LEAST NEXT WEEKEND.
AVIATION /12Z TAFS THROUGH 12Z SUNDAY/
ISSUED AT 433 AM MST SAT JAN 10 2026
DRY CONDITIONS CONTINUE AS HIGH PRESSURE REMAINS IN PLACE OVER
EASTERN IDAHO. LOW CLOUDS REMAIN JUST OUTSIDE OF MOST OF OUR
TERMINALS THIS MORNING, WITH CIGS BACK AND FORTH BETWEEN VFR AND
MVFR AT DIJ WITH FEW TO THEN BKN CLOUDS RIGHT AROUND 3000 FT AGL.
SOME UPPER LEVEL CLOUDS MOVING OVER DIJ ARE PRODUCING SOME LIGHT
SEEDER-FEEDER SNOW SHOWERS, TOO. ANY LOW STRATUS IS EXPECTED TO
REMAIN OUTSIDE OF SUN TODAY, SO VFR CONDITIONS WILL PERSIST THERE.
THE NBM SHOWS A 10 TO 20 PERCENT CHANCE OF MVFR CIGS DRIFTING INTO
PIH THROUGH THE EARLY MORNING. MVFR TO NEAR IFR CIGS WERE
SOLIDLY IN PLACE NORTH OF IDA AT RXE EARLIER THIS MORNING AND
THE NBM SHOWS A 30 TO 40 PERCENT CHANCE OF THOSE LOW CLOUDS
DRIFTING FARTHER SOUTH INTO IDA BEFORE 22Z TODAY. WILL CONTINUE
TO WATCH THIS MOVEMENT AND AMD IF/AS NEEDED. WINDS WILL BE LIGHT
TODAY AND MORE PATCHY FOG IS IN THE FORECAST FOR TONIGHT/EARLY
SUNDAY MORNING. THE NBM CURRENTLY SHOWS ABOUT A 20 TO 30 PERCENT
CHANCE OF MVFR CIGS AT BYI, PIH, IDA, AND DIJ TONIGHT, SO WILL
KEEP BORDERLINE VFR TO MVFR CIGS OR SCT MVFR CIGS IN THE TAFS.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
