SHORT TERM /THROUGH THURSDAY/
ISSUED AT 207 PM MST WED JAN 7 2026
CLOUDS WILL CONTINUE TO INCREASE AND SPREAD ACROSS THE AREA AS
WE HEAD INTO THE LATE AFTERNOON AND EVENING HOURS. THIS WILL
OCCUR THANKS TO MOISTURE STREAMING UP FROM THE SOUTH BEING
WORKED ON BY A SHORTWAVE. MODELS ARE INDICATING SOME HEAVIER
PRECIP POSSIBLE AT TIMES AS THIS WAVE MOVES THROUGH. THERE MAY
BE A BRIEF LULL IN ACTIVITY BEFORE A SECOND, MORE POTENT, COLD
FRONT AND UPPER LEVEL TROUGH STARTS MOVING THROUGH TOMORROW
AFTERNOON. AS THE FRONT MOVES THROUGH, IT WILL BECOME THE FOCUS
OF HEAVIER SNOWFALL FOR THE HIGHER TERRAIN AND ALSO MUCH OF THE
LOWER VALLEYS. EVENTUALLY, A CLOSED LOW WILL FORM AT THE BASE
OF THE UPPER LEVEL TROUGH AND THIS ADDED LIFT WILL ALLOW SOME
HEAVIER SNOWFALL FOR THE CENTRAL AND SOUTHERN MOUNTAINS. IT'S
DURING THIS TIMEFRAME THAT THE SOUTHERN VALLEYS MAY ALSO SEE A
FEW INCHES OF SNOW. THE WINTER WEATHER ADVISORIES REMAIN IN
EFFECT AND ADDED THE CENTRAL MOUNTAINS, SAN JUANS AND THE LA
SALS AND ABAJOS IN UTAH ABOVE 8500 FEET, FOR 4 TO 8 INCHES OF
NEW SNOW. SOME STRONGER WIND GUSTS WILL ACCOMPANY FRONTAL
PASSAGE SO WHILE TRAVELLING TOMORROW AFTERNOON AND EVENING, BE
AWARE THAT SURFACE VISIBILITIES MAY FLUCTUATE RAPIDLY UNDER
HEAVIER SNOW/SNOWSHOWERS. CLOUDS AND PRECIPITATION WILL KEEP
TEMPERATURES COOLER THAN SEEN RECENTLY BUT THE REAL PUSH OF COLD
AIR WILL BE FRIDAY.
LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/
ISSUED AT 207 PM MST WED JAN 7 2026
SOME SNOW LOOKS TO LINGER THROUGH FRIDAY MORNING BEFORE TAPERING OFF
FRIDAY AFTERNOON AS THE LOW PRESSURE TROUGH EXITS THE REGION. DRIER
AIR WILL MOVE IN BEHIND THIS SYSTEM. MUCH COLDER AIR WILL BE LEFT IN
ITS WAKE THOUGH AS H7 TEMPERATURES DROP TO THE -12C TO -16C RANGE.
SO COULD SEE SOME NORTHERLY OROGRAPHICS KEEP SNOW GOING ON THE
NORTHERN SLOPES AND INTO THE UNCOMPAHGRE GORGE IN THE NW SAN
JUANS A BIT LONGER. TEMPERATURES WILL BE AROUND 5 DEGREES BELOW
NORMAL IN THE VALLEYS AND 10 TO 20 DEGREES BELOW SEASONABLE IN
THE MOUNTAINS IN THE WAKE OF THIS SYSTEM. WHAT FOLLOWS IS A
DRIER PERIOD A HIGH PRESSURE RIDGE AMPLIFIES OUT WEST THIS
WEEKEND INTO THE COMING WEEK, CAUSING ANY SYSTEMS OR MOISTURE TO
BE STEERED UP AND AROUND THE BLOCKING RIDGE. WE STILL MAINTAIN
A NORTHERLY FLOW SO THE PARK RANGE COULD SEE SOME LIGHT
OROGRAPHIC SNOW FROM TIME TO TIME BUT OVERALL, DRY CONDITIONS
WITH TEMPERATURES WARMING BACK TOWARDS SEASONABLE THIS WEEKEND
AND EVENTUALLY BACK TO 5 TO 10 DEGREES ABOVE NORMAL NEXT WEEK.
AVIATION /00Z TAFS THROUGH 00Z FRIDAY/
ISSUED AT 436 PM MST WED JAN 7 2026
WIDESPREAD RAIN AND SNOW SHOWERS ARE EXPECTED TO ARRIVE TONIGHT.
MOST TERMINALS HAVE A CHANCE TO SEE LIGHT SNOWFALL BEFORE
MIDNIGHT, BUT THE GREATEST IMPACTS AREN'T EXPECTED UNTIL NEAR
AND AFTER SUNRISE TOMORROW. CIGS ARE LIKELY TO FALL BELOW ILS
BREAKPOINTS AT ALL TERMINALS (EXCEPT FOR KVEL AND KCNY) AS
STORMS PASS THROUGH. SHOWERS SHOULD PERIODICALLY DROP VIS TO
MVFR OR IFR CONDITIONS. STRONGER RAIN AND SNOWFALL COULD PUSH
CONDITIONS FURTHER TO LIFR, BUT CONFIDENCE IS LOW ON WHEN,
WHERE, AND IF THIS WOULD OCCUR, THUS NO TAF'S INCLUDE VIS BELOW
1SM YET.
