KEY MESSAGES
- DRY WEATHER CONTINUES INTO NEXT WEEK
- INVERSION CONDITIONS PERSIST WITH LIMITED FOG/STRATUS
- OVERALL SLOW WARMING TREND THROUGHOUT THIS WEEK
SHORT TERM /THROUGH TUESDAY NIGHT/
ISSUED AT 1151 AM MST MON JAN 12 2026
WE ARE SEEING HIGH AND MID LEVEL CLOUDS STREAMING ACROSS OUR
AREA, BUT THAT IS THE EXTENT OF ANY "MOISTURE" IN OUR AREA.
EXPECT THIS TREND TO CONTINUE AS THE RIDGE REMAINS IN PLACE.
INVERSIONS ARE PRESENT BUT NOT AS STRONG AS THEY COULD BE IN THE
RIDGE WAS FIRMLY OVERHEAD. IT WILL SLIDE A BIT FARTHER NORTH AND
EAST, BUT STILL ISN'T EXPECTED TO BE CENTERED OVER US. WE DID
HAVE TO TWEAK TEMPERATURES DOWN IN SOME VALLEYS BASED ON TRENDS.
WHERE INVERSIONS HOLD A BIT, HIGHS WILL BE IN THE 20S AND 30S.
WITHIN THE INVERSION LAYER OR WHERE WE CAN GET A BIT MORE MIXING
TO HAPPEN, TEMPERATURES WILL PUSH HIGHER INTO THE 30S AND EVEN
40S. WE'VE HAVE LIMITED FOG AND LOW CLOUDS, MAINLY AROUND BEAR
LAKE AND THE STANLEY BASIN ON ANY TYPE OF "WIDESPREAD" BASIS. WE
DID KEEP THAT IN THE FORECAST THROUGH MIDWEEK, AND WILL KEEP
TWEAKING IT BASED ON ANY DEVELOPING TRENDS.
LONG TERM /WEDNESDAY THROUGH SUNDAY/
ISSUED AT 1151 AM MST MON JAN 12 2026
THERE IS STILL NO POTENTIAL FOR PRECIPITATION THROUGH THE
WEEKEND, AND THIS EVEN EXTENDS INTO NEXT WEEK. WE DO SEE THE
RIDGE SHIFTING WEST A BIT BY THE END OF THIS WEEK, WHICH MAY
KICK UP THE WIND A BIT AND ALSO TURN THE PATTERN MORE NORTHERLY
OR NORTH-NORTHWEST OVER THE STATE. THE CURRENT BLEND OF MODELS
DOESN'T REALLY SHOW ANY PROLONGED TREND DOWNWARD, AND MAINTAINS
TEMPERATURES SLOWLY WARMING UP. THE CONCERN THERE IS UNTIL WE
GET INVERSIONS TO TRULY BREAK, IT MAY BE TOO AGGRESSIVE WITH
WARMER TEMPERATURES. WITH THE FLOW ALSO TURNING MORE NORTHERLY
AGAIN, THE BLEND MAY NOT BE CAPTURING ANY TYPE OF COOLDOWN VERY
WELL AT ALL. WE MAY NEED TO MAKE ADJUSTMENTS TO TEMPERATURES IN
THE COMING DAYS.
AVIATION /18Z TAFS THROUGH 18Z TUESDAY/
ISSUED AT 1118 AM MST MON JAN 12 2026
VFR CONDITIONS LIKELY TO PREVAIL THROUGH THE PERIOD WITH LIGHT

EASTERN IDAHO. WILL LIKELY SEE SOME MID/HIGH LEVEL CLOUDS
STREAKING ACROSS THE REGION AT TIMES BUT SHOULD BE OF LITTLE
IMPACT.
