KEY MESSAGES
- VERY WARM ON THE PLAINS THROUGH CHRISTMAS, TRENDING COOLER AT THE
END OF THE PERIOD.
- PATTERN SHIFT IS EXPECTED TO BRING INCREASING SNOW CHANCES IN THE
MOUNTAINS TOWARDS CHRISTMAS.
SHORT TERM /THROUGH SUNDAY/
ISSUED AT 221 PM MST SAT DEC 20 2025
STRONG ZONAL FLOW REMAIN IN PLACE ACROSS THE REGION, WITH SLIGHTLY
COOLER TEMPERATURES SETTING IN. MEANWHILE, SNOWFALL WILL CONTINUE
OVER PORTIONS OF THE CENTRAL MOUNTAINS THROUGH THE REST OF THE DAY.
TOTAL ACCUMULATIONS THROUGH THIS EVENING ARE STILL HEAVIEST OVER
NORTHWEST LAKE COUNTY, WHILE THE REST OF THE SAWATCH AND MOSQUITO
RANGES RECEIVE A FEW INCHES. MEANWHILE, THE REST OF THE AREA WILL
REMAIN DRY.
WINDS WILL FINALLY START WEAKENING OVER THE AREA TONIGHT AS THE JET
ALOFT SHIFTS NORTHWARD , WITH SOME MODEST UPSLOPING OVER THE
MOUNTAINS/PLAINS INTERFACE. ALTHOUGH, WINDS ALOFT, ABOVE ABOUT 5,000
FEET, REMAIN GUSTY AND MAINLY OUT OF THE WEST DUE TO THE GREATER
SYNOPTIC FLOW. WITH THE ABSENCE OF ANY STRONG DOWNSLOPING OUT EAST,
OVERNIGHT LOWS WILL BE MUCH COLDER IN SOME AREAS TONIGHT, TYPICALLY
IN THE TEENS-20S AT MOST LOCATIONS, THOUGH LOW-30S MAY LINGER RIGHT
ALONG THE TERRAIN.
WARM TEMPERATURES RETURN ON SUNDAY, THOUGH WE MAY BE A FEW DEGREES
COOLER THAN TODAY. MID-LEVEL CLOUDS WILL STICK AROUND, BUT ARE
EXPECTED TO SLOWLY DWINDLE AS THE DAY GOES ON. HIGHS WILL BE IN THE
50S TO LOW-60S OVER THE PLAINS AND VALLEYS. WINDS WILL BE MUCH
LIGHTER, WITH A FEW GUSTS FROM THE SOUTH OVER THE PLAINS, WHILE THE
AREA REMAINS GENERALLY DRY.
LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/
ISSUED AT 206 AM MST SAT DEC 20 2025
WELL, THERE IS GOOD AND BAD (WEATHER) NEWS IN THE LONG RANGE. THE
BAD NEWS IS IT IS NOT GOING TO FEEL LIKE CHRISTMAS OVER THE PLAINS
THIS WEEK. THE JET IS GOING TO REMAIN TO OUR NORTH OVER WYOMING
AND MID LEVEL FLOW IS GOING TO COME OUT OF THE WEST-SOUTHWEST. MAX
TEMPS OVER THE PLAINS ON SUNDAY IN THE 55 - 65 RANGE WILL BE
REPLACES BY TEMPS IN THE 60S AND 70S (WITH POSSIBLY AT 80 HERE AND
THERE) THROUGH THIS WEEK. THESE TEMPS ARE RIDICULOUSLY WAY ABOVE
NORMAL AS MAX TEMPS ON THE PLAINS SHOULD TYPICALLY BE IN THE 40S. I
EXPECT WE WILL SEE SOME RECORDS FALL CHRISTMAS WEEK, WITH THE
WARMEST TEMPS THIS MONDAY.
THE GOOD NEWS IS MOISTURE WILL BE INCREASING WITH THE SOUTHWEST FLOW
AND THE MOUNTAINS ALONG ALL OF THE CONTDVD SHOULD SEE SNOW START
TO RAMP UP PERUSING THE DESI GUIDANCE SHOWS THE SNOW STARTING TO
RAMP UP CHRISTMAS EVE ALONG THE DIVIDE AND LASTING INTO THE WEEKEND.
OVERALL AMOUNTS DONT LOOK ALL THAT HIGH(UP TO 2 FEET THROUGH XMAS-EVE
INTO THE WEEKEND), BUT ANY ACCUMULATING SNOW IS GOOD SNOW IN THE
MOUNTAINS.
IT DOES APPEAR IT WILL CONTINUE TO GET MORE "TROUGHY" OVER THE WEST
XMAS WEEKEND INTO THE FOLLOWING WEEK, AND COOLER, POSSIBLY WETTER
WEATHER SHOULD MOVE INTO ALL OF THE REGION. \/HODANISH
