AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
449 PM MST SAT JAN 10 2026
KEY MESSAGES
- HIGH PRESSURE CONTINUES TO BRING MOSTLY DRY WEATHER INTO NEXT
WEEK.
- GRADUAL WARMING BEGINS THIS WEEKEND.
- LOW CONFIDENCE POTENTIAL FOR PATCHY FOG AGAIN TONIGHT.
SHORT TERM /THROUGH SUNDAY NIGHT/
ISSUED AT 154 PM MST SAT JAN 10 2026
UPPER RIDGE REMAINS IN PLACE PER SATELLITE IMAGERY. LOW CLOUD DECK
STILL IN PLACE ACROSS THE NORTHEAST QUARTER. ADDITIONAL MID AND HIGH-
LEVEL MOISTURE WORKING ACROSS THE REGION WILL STILL HAVE SOME
POTENTIAL TO PRODUCE POCKETS OF SEEDER-FEEDER SNOWS, BUT CONFIDENCE
IS LOW SO LEFT FORECAST DRY. THE HIGH CLOUDS SHOULD HELP TO INHIBIT
FOG FORMATION OVERNIGHT, AND THE NBM PROBABILITY OF VIS LESS THAN 5
MILES IS ONLY AROUND 20 PERCENT FOR MOST OF THE REGION. THERE IS A
LITTLE BETTER CONFIDENCE ONCE AGAIN IN THE CACHE VALLEY, SO RETAINED
SOME MENTION THERE. OTHERWISE, THE TEMPERATURE TREND INTO SUNDAY
CONTINUES TO TICK SLIGHTLY UPWARD, AND OTHER THAN THE AFOREMENTIONED
SEEDER-FEEDER POTENTIAL, NO PRECIPITATION IS EXPECTED.
LONG TERM /MONDAY THROUGH SATURDAY/
ISSUED AT 154 PM MST SAT JAN 10 2026
HIGH PRESSURE WILL MAINTAIN AN INACTIVE PATTERN FOR THE DURATION OF
THE EXTENDED PERIOD. THE SOLE CONCERN WILL BE THE POTENTIAL FOR
OVERNIGHT AND EARLY MORNING FOG AND DEGRADED AIR QUALITY AS A RESULT
OF TEMPERATURE INVERSIONS. OTHERWISE, CONDITIONS WILL REMAIN DRY AND
WINDS LIGHT UNDER HIGH PRESSURE. DAYTIME TEMPERATURES WILL SPAN THE
30S AND 40S, REACHING NEAR 10 DEGREES ABOVE NORMAL FOR THIS TIME OF
YEAR. SOME LOCATIONS IN THE EASTERN MAGIC VALLEY AND SOUTH HILLS
REGIONS WILL WARM TO WITHIN A FEW DEGREES OF 50F BY EARLY TO MIDDLE
OF NEXT WEEK. AS INDICATED BY THE 500MB ENSEMBLE CLUSTERS,
CONFIDENCE IS INCREASING AMONGST ENSEMBLES THAT THE RIDGE OF HIGH
PRESSURE WILL MAINTAIN CONTROL OF THE UPPER-LEVEL PATTERN INTO
AT LEAST EARLY THE FOLLOWING WEEK.
AVIATION /00Z TAFS THROUGH 00Z MONDAY/
ISSUED AT 439 PM MST SAT JAN 10 2026
EXPECTING MAINLY VFR CONDITIONS THROUGH SUNDAY WITH A SMALL
CHANCE OF MVFR TO IFR CEILINGS OVERNIGHT AT IDA AND DIJ BUT FOR
NOW THINK OVERWHELMING MAJORITY OF TIME VFR EVEN AT THOSE SITES.
WINDS WILL BE LIGHT. NO IMPACTS EXPECTED AT PIH, SUN AND BYI.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
