OVERVIEW: AN UPPER LEVEL WAVE OVER THE INTERMOUNTAIN WEST
(TODAY) WILL PROGRESS ESE-E ACROSS THE 4-CORNERS (TONIGHT) AND
SOUTHERN PLAINS (MONDAY). IN THE LOWER LEVELS, ~1035 MB ARCTIC
HIGH PRESSURE OVER THE DAKOTAS AND CENTRAL PLAINS (TODAY) WILL
SHIFT E ACROSS THE CENTRAL AND NORTHERN MS RIVER VALLEY
(TONIGHT) AND OHIO VALLEY (MONDAY).
PRECIPITATION/SNOW WILL DEVELOP OVER THE REGION TONIGHT,
BEGINNING (IN EARNEST) ~06 UTC IN EASTERN CO, AS THE
AFOREMENTIONED UPPER WAVE TRAVERSES THE 4-CORNERS. RECENT RUNS
OF HIGH-RES GUIDANCE (HRRR, RAP, NAM NEST) SUGGEST THAT STRONG
MID-LEVEL WARM ADVECTION IN ADVANCE OF THE APPROACHING WAVE..
AND STRONG CYCLONIC SHEAR VORTICITY ON THE NORTHERN FRINGE OF A
~115 KNOT JET STREAK (PROGGED TO DEVELOP OVER SOUTHEAST CO AND
WESTERN KS OVERNIGHT).. MAY AID IN THE DEVELOPMENT OF A NARROW
CORRIDOR/BAND OF HEAVIER PRECIPITATION ALONG AND NEAR I-70 IN
EASTERN CO AND NORTHWEST KS (INCLUDING BURLINGTON AND GOODLAND)
BETWEEN MIDNIGHT AND SUNRISE (06-12 UTC) MONDAY MORNING. GIVEN
THAT THE MAJORITY OF HIGH-RES GUIDANCE SUPPORT SUCH A SCENARIO..
STORM TOTAL SNOW ACCUMULATIONS HAVE BEEN ADJUSTED ACCORDINGLY.
IN GENERAL, EXPECT ACCUMULATIONS RANGING FROM A DUSTING TO 2-3"
THOUGH.. LOCALLY HIGHER AMOUNTS (3-5") ARE CERTAINLY POSSIBLE
WITHIN ANY NARROW/HEAVY BANDS. WITH LIGHT (5-15 MPH) E TO SE
WINDS EXPECTED LATE TONIGHT AND MONDAY MORNING, BLOWING/DRIFTING
SNOW IS NOT ANTICIPATED WHILE PRECIPITATION IS OCCURRING.
PRECIPITATION WILL RAPIDLY END FROM WEST-TO-EAST BETWEEN SUNRISE
(EASTERN CO) AND NOON (HWY 283/HILL CITY) AS THE UPPER WAVE
PROGRESSES EAST OF THE TRI-STATE AREA. IN AREAS WITH FRESH SNOW
COVER.. SOME BLOWING/DRIFTING SNOW IS POSSIBLE MONDAY AFTERNOON
(AFTER PRECIPITATION ENDS) AS WINDS SHIFT TO THE NW AND INCREASE
TO ~15-25 MPH. EXPECT HIGHS IN THE MID 20'S TO MID 30'S AND
OVERNIGHT (TUE MORNING) LOWS RANGING FROM THE SINGLE DIGITS TO
MID-TEENS, COLDEST WHERE SNOW COVER IS PRESENT.
LONG TERM /TUESDAY THROUGH SUNDAY/
ISSUED AT 205 PM MST SUN NOV 30 2025
LONG RANGE GUIDANCE SUGGESTS A PREDOMINANTLY DRY PATTERN
(LITTLE POTENTIAL FOR PRECIPITATION) CHARACTERIZED BY A MODEST
WARMING TREND (TUE) AS THE ARCTIC AIRMASS EXITS THE REGION /
DRAINS DOWNHILL TO THE EAST AND A LOW-LEVEL SOUTHERLY RETURN
FLOW PATTERN ENSUES.. FOLLOWED BY A COOLING TREND ASSOC/W
ANOTHER COLD FRONTAL PASSAGE MID-WEEK.. WITH BELOW AVERAGE
TEMPERATURES PERSISTING INTO LATE-WEEK.
AVIATION /00Z TAFS THROUGH 00Z TUESDAY/
ISSUED AT 433 PM MST SUN NOV 30 2025
CURRENT VFR CONDITIONS OVER KGLD AND KMCK ARE EXPECTED TO
DECLINE TO MVFR AND IFR AFTER 05-09Z FOR KMCK AND 07-09Z FOR
KGLD AS SNOW MOVES OVER THE AREA. VISIBILITY RESTRICTIONS DOWN
TO 2SM IS POSSIBLE FOR BOTH TERMINALS BETWEEN 09-12Z DUE TO THE
SNOWFALL RATE. CURRENT THINKING AS THAT SNOW STOPS FALLING OVER
KGLD BETWEEN 14-16Z AND KMCK FROM 14-17Z. BOTH TERMINALS COULD
SEE ANYWHERE FROM A TRACE TO 2" WITH LOCALLY HEAVIER AMOUNTS
POSSIBLE OVER KGLD SHOULD A SNOWBAND SET UP AND IMPACT THE
TERMINAL. WINDS ARE EXPECTED TO REMAIN OUT OF THE SOUTHEAST AT
5-10 KTS BEFORE GRADUALLY SHIFTING OUT OF THE WEST TO BECOME
NORTHWESTERLY BY 21Z MONDAY AFTERNOON AT ~10-15 KTS. DURING THE
AFTERNOON HOURS, GUSTS TO 20 KTS WILL BE POSSIBLE OVER KGLD AND
COULD LEAD TO SOME BLOWING SNOW ALREADY ON THE GROUND GIVEN THE
POWDERY NATURE OF THE SNOW.
