ISSUED AT 233 PM MST SAT DEC 6 2025
SYSTEM IN NORTHWEST FLOW CONTINUES TO BRING WIND DRIVEN SNOW TO THE
CENTRAL MOUNTAINS THIS AFTERNOON INTO THE EVENING BEFORE DECREASING
OVERNIGHT AS DRIER AIR WORKS IN. ALSO SEEING SOME INSTABILITY
ENHANCED SNOW BANDS SPREAD DOWN INTO THE ADJACENT LOWER ELEVATIONS
OF EL PASO COUNTY, MAINLY NORTHERN AREAS THIS AFTERNOON. THESE WILL
QUICKLY PUSH EASTWARD AND DIMINISH TOWARDS EARLY EVENING. WINDS WILL
REMAIN STRONG THROUGH THE EVENING BEFORE SHIFTING FROM THE NORTH AND
TAILING OFF AS THE EMBEDDED ENERGY PASSES OFF TO THE SOUTHEAST. THIS
WILL LEAVE CLEARING SKIES OVER THE REGION OVERNIGHT WHICH WILL ALLOW
TEMPERATURES TO COOL EFFICIENTLY ONCE THE WINDS DECOUPLE. COLDEST
READINGS TONIGHT WILL BE ACROSS THE INTERIOR VALLEYS WHERE SNOW
COVER LINGERS (MAINLY SAN LUIS VALLEY AND UPPER RIO GRANDE).
TEMPERATURES FOR THESE AREAS COULD DROP INTO THE SINGLE DIGITS.
MEANWHILE, NORTHWESTERLY FLOW WILL KEEP SOME ISOLATED OROGRAPHIC
SNOW SHOWERS CONTINUING ACROSS THE CENTRAL MOUNTAINS OVERNIGHT, BUT
ADDITIONAL SNOWFALL AFTER MIDNIGHT WILL BE SPOTTY AND LIGHT.
THIS WILL ALLOW FOR IMPROVING TRAVEL CONDITIONS ACROSS THE
CENTRAL MOUNTAINS ONCE THE SNOW LETS UP THIS EVENING.
TEMPERATURES ON SUNDAY WILL BE COOLER, ESPECIALLY ACROSS THE PLAINS
BEHIND THE COLD FRONT WHERE READINGS WILL BE AROUND 5 TO 10 DEGREES
COOLER DUE TO LESS MIXING AND LIGHTER WINDS. OTHERWISE, IT IS THE
BEGINNING OF A DRYING TREND WHICH WILL CONTINUE INTO NEXT WEEK. -KT
LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/
ISSUED AT 208 AM MST SAT DEC 6 2025
FORM MONDAY THROUGH WEDNESDAY, TEMPS WILL GRADUALLY WARM EACH
DAY AND IT WILL BE DRY. FROM MIDWEEK ONWARDS, THERE IS QUITE A
BIT OF SPREAD IN THE TEMPS ALTHOUGH IT WILL LIKELY BE
RELATIVELY MILD OVER THE REGION. THIS VARIABILITY IS LIKELY DUE
WITH INCONSISTENCIES IN THE MID RANGE GUIDANCE ON THE PLACEMENT
OF THE JET OVER THE REGION (GFS IS FARTHER NORTH WITH THE JET
DURING THIS TIME AS COMPARED TO THE EC). ALL THE GUIDANCE SHOWS
ANOTHER WEAK WAVE MOVING IN THE NW FLOW ALOFT TO THE NORTH OF
THE REGION, AND THIS WILL BRING A GOOD CHANCE OF SOME MORE SNOW
SHOWERS TO THE CENTRAL MTNS DURING THE WED/THU TIME FRAME, WITH
A BIT COOLER TEMPS OVER THE AREA. NEXT WEEKEND LOOKS MILD AND
DRY. \/HODANISH
