CERTAIN THAT WARNING CRITERIA WILL BE MET OVER THE HYR ELEVATIONS
OF THE SAN JUANS AND LA GARITAS. FAIRLY DEEP MOIST LAYER WILL
COMBINE WITH PERSISTENT SRLY FLOW LATE MONDAY NIGHT INTO TUE
MORNING...AND BY THE TIME THINGS WIND DOWN TUE NIGHT...SHOULD SEE
WIDESPREAD ACCUMULATIONS IN EXCESS OF ONE FOOT...POSSIBLY AS HIGH
AS TWO FEET OVER WOLF CREEK REGION.

AS MENTIONED IN UPDATED HAZARDOUS WEATHER OUTLOOK...STILL A MAJOR
HEADACHE IN TRYING TO PIN DOWN SNOWFALL TIMING AND AMTS FOR THE
POPULATION CENTERS ALONG INTERSTATE 25. SNOWFALL IS ALMOST
CERTAIN...BUT WHETHER IT WILL BE A MINOR NUISANCE SNOWFALL OR
TRAFFIC-STOPPER IS STILL UP IN THE AIR. BEST GUESS AT THIS POINT
IS MODERATE ACCUMULATIONS RANGING FROM 3 TO 6 INCHES...BASED ON AN
ENSEMBLE OF RECENT MODEL RUNS. AS AN EXAMPLE OF HOW TRICKY THE
FORECAST IS...MOST RECENT WRF/NAM PRODUCES THE EQUIVALENT OF
AROUND 2 INCHES FOR PUEBLO AND EL PASO COUNTIES...WHILE PREVIOUS
18Z RUN WAS IN THE 8 TO 10 INCH RANGE. DIFFERENCE IS LARGELY IN
THE TIMING OF THE WAA SNOWBAND AHEAD OF THE UPPER LOW. EARLIER RUN
WAS SLOWER...BRINGING IN THE HEAVY QPF LATE TUE AND CONTINUING
THRU WED MORNING. LATEST RUN IS FASTER...BEGINNING SNOWFALL EARLY
TUE MORNING BUT THEN CUTTING OFF THE PRECIP AS FLOW ALOFT RAPIDLY
SHIFTS TO THE NW BEHIND THE LOW.

WILL HAVE TO WATCH THIS SYSTEM ON AN HOURLY BASIS. DOES NOT APPEAR
THAT THE TROWEL WILL BE A SIGNIFICANT FACTOR...AS CONSENSUS SHOWS
IT WILL BE TOO FAR TO THE N AND E OF THE REGION. HOWEVER...WITH
GOOD DEGREE OF SATURATION AND PERSISTENT LIGHT TO MODERATE UPSLOPE
FLOW...SHOULD STILL SEE SOME RESPECTABLE SNOWFALL FROM THIS SYSTEM.
AND...THERES STILL PLENTY OF TIME FOR SURPRISES

SNOW LOVERS...IF WE DO NOT END UP WITH A MAJOR SNOWFALL FROM THIS
MIDWEEK STORM...DO NOT DESPAIR...AS THERE LOOKS TO BE AN EXTENDED
PERIOD OF UNSETTLED WEATHER AHEAD THROUGH THE NEW YEAR.
IR IMAGERY TONIGHT SHOWS A STRING OF INCIPIENT STORMS LINED UP
THROUGH THE N PACIFIC...AND AN ACTIVE ITCZ WITH EVIDENCE OF ERLY
TRAVELLING WAVES...ALL RECIPES FOR SOME REAL WINTER WEATHER. AFTER
STORM NUMBER ONE...ANOTHER...EVEN COLDER...SYSTEM COULD HIT THE
REGION LATE FRI INTO SATURDAY. THEN...LATEST GFS PROGS YET ANOTHER
SYSTEM FOR LATE IN THE WEEKEND...POTENTIALLY CAUSING SOME SERIOUS
HOLIDAY HEADACHES. WHILE THE STORM ON TUE WILL FEATURE RELATIVELY
TAME TEMPS OF AROUND MINUS 8 AT H7...THE LATER SYSTEMS WILL COME
WITH H7 TEMPS IN A PRIME DENDRITIC ZONE OF AROUND MINUS 13-15.
SO...PLENTY OF HOLIDAY SNOW POTENTIAL TO COME

.PREV DISCUSSION... /ISSUED 334 PM MST SUN DEC 17 2006/

SHORT TERM...
(TONIGHT AND MONDAY)

MAIN CONCERN IS PCPN POTENTIAL. TONIGHT AN UPR TROF WL BE OVR UT AND
SRN NV AND INTO SRN CA.  BY 12Z MON A CLOSED LOW IS EXPECTED TO BE
CENTERED OVR SRN CA WHERE IT WL REMAIN THRU THE DAY.  AHEAD OF THIS
SYSTEM...SW FLOW WL CONTINUE TO BRING MID AND HIGH LEVEL MSTR OVR
THE FORECAST AREA. QG ASCENT LOOKS FAIRLY GOOD OVR THE AREA
ESPECIALLY THE WRN HALF...ALONG WITH UPR JET LYING OVR THE AREA. A
LOBE OF PV WL LIE OVR AREAS FROM ABOUT THE PIKES PEAK REGION SWWRD
TO THE SW MTS...AND THIS WL SHIFT EWRD ACRS THE AREA ON MON.  BEST
PCPN POTENTIAL TONIGHT AND MON WL BE IN AREAS MOST AFFECTED BY THE
UPR DYNAMICS WHICH WL MAINLY BE OVR THE MTS AND HIGH VALLEYS.  SNOW
WILL CONTINUE FALLING ACRS THE SW AND PORTIONS OF THE CENTRAL MTS
TONIGHT AS THE MSTR LAYER REMAINS FAIRLY DEEP AND OROGRAPHICS ARE
STILL GOOD FOR THE SW MTS.  WL KEEP THE SNOW AND BLOWING SNOW
ADVISORIES IN EFFECT FOR ZONES 66 AND 68...BUT ONLY A FEW ADDITIONAL
INCHES SHOULD FALL TONIGHT. BY MON MORNING THE MSTR LAYER BECOMES
VERY S51OW AND REMAINS THAT WAY THRU THE DAY...BUT SOME ISOLD TO
SCT SHOWERS WL STILL BE POSSIBLE.  OVR ERN AREAS MODEL SOUNDINGS
SHOW LOW LEVEL MSTR INCREASING LATE TONIGHT AND REMAINING OVR THE
AREA THRU MON....SO THERE SHOULD BE A LOT OF CLOUDS.  ALONG WITH
THAT THE LOW LEVEL FLOW WL BE UPSLOPE...SO SOME SNOW ALONG AND NR
THE ERN MTS WL ALSO BE POSSIBLE. TEMPS AT H7 ON MON WL BE SEVERAL
DEGREES COOLER THAN TODAY AND MAX TEMPS WL NOT BE ALL THAT
WARM...AROUND 10 DEGREES BELOW NORMAL OVR ERN AREAS.

LONG TERM...
(MONDAY NIGHT THROUGH SUNDAY)

TIMING/MAGNITUDE OF POTENTIALLY SIGNIFICANT SNOW EVENT FOR MON NIGHT
THROUGH WED NIGHT STILL THE MAIN FCST CONCERN.

SHORT RANGE MODELS AND GFS ENSEMBLES APPEAR TO BE COMING INTO BETTER
CONSENSUS WITH TRACK OF CLOSED UPPER LOW WHICH MOVES FROM SRN CA/SW
AZ MON MORNING ACROSS AZ ON TUES THEN ACROSS NRN NM INTO ERN CO ON
WED.  GFS ELONGATES THE UPPER LOW TUES NIGHT AS IT MOVES INTO ERN
CO...WHILE NAM KEEPS UPPER LOW MORE CONSOLIDATED AND FARTHER TO THE
SOUTH ACROSS CEN NM TUES NIGHT...THEN JUMPS THE LOW INTO ERN CO ON
WED TO A SIMILAR POSITION WITH THE GFS. THUS WAA SHOULD SPREAD SNOW
UP FROM THE SOUTHWEST MON NIGHT...WITH THE HEAVIEST SNOW ACROSS THE
SW MTS. H7 FLOW IS MORE SOUTHERLY TO SOUTHEASTERLY...SO ANY
OROGRAPHICS WOULD FAVOR THE NRN PORTIONS OF THE SAN LUIS
VALLEY...AND EAST SLOPES OF THE ERN SAN JUANS AND LA GARITAS.
HOWEVER...WITH STRONG DIFLUENCE ALOFT...MUCH OF SOUTH WEST CO COULD
SEE SIGNIFICANT SNOWFALL AMOUNTS MON NIGHT/TUES.  THIS AREA WILL
LIKELY NEED A WINTER STORM WATCH...BUT WITH HIGHLIGHTS ONGOING...AND
ONSET OF HEAVY SNOW BEING A LATE 3RD PERIOD EVENT...PREFER TO HOLD
OFF FOR NOW.

SNOW WILL SPREAD NORTHWARD ACROSS THE EASTERN PLAINS MON NIGHT/TUES
AS UPPER LOW APPROACHES SW CO AND AREA OF ISENTROPIC UPGLIDE SPREADS
ACROSS THE REGION.  ONCE AGAIN...APPEARS EVENT WILL BE DRIVEN MORE
BY SYNOPTIC LIFT...HOWEVER SOME SE LOW LVL FLOW MAY LOCALLY ENHANCE
SNOWFALL ALONG THE EASTERN MTS TUES MORNING. GFS WRAPS DRY SLOT
AROUND THE UPPER LOW ACROSS ERN CO TUES NIGHT...WITH BEST UPGLIDE
SHIFTING EAST OF THE AREA. THIS SHUTS DOWN THE SNOWFALL SOME TUES
NIGHT...HOWEVER WITH TIGHTER UPPER LOW IN NAM12...NAM PORTRAYS MUCH
HEAVIER SNOWFALL FOR EASTERN CO TUES NIGHT.  OVERALL STILL LOOKS
LIKE THE POTENTIAL FOR A SIGNIFICANT SNOWFALL EVENT FOR THE ERN
PLAINS AS WELL...BUT DETAILS STILL TOO UNCERTAIN TO WARRANT A 4TH
PERIOD AND BEYOND WATCH. FOR NOW...MODEL SOUNDINGS SUGGEST PCPN TYPE
SHOULD STAY AS SNOW...THOUGH COULD SEE SOME ICE PELLETS BRIEFLY TUES
NIGHT ACROSS THE FAR SE CORNER UNDER WAA ALOFT.

UPPER LOW INTENSIFIES AS IT LIFTS TO THE NE WED/WED NIGHT...AND SE
PLAINS COMING UNDER THE INFLUENCE OF THE TROWAL. ONCE
AGAIN...EXACT POSITION OF THE TROWAL STILL UNCERTAIN...AND GFS
INDICATES SOME DRY WEDGES WILL BE WRAPPING AROUND THE UPPER LOW
WHICH COULD SHUT DOWN SNOWFALL. BUT OVERALL SNOW SHOULD BE WINDING
DOWN BY THURS.

NEXT SYSTEM IS QUICK ON ITS HEALS WITH LATEST GFS NOW DIVING NEXT
UPPER LOW SOUTHWARD ACROSS NV ON FRI...THEN SENDS CLOSED LOW
SOUTHWARD INTO OLD MEXICO BY SAT MORNING.  THIS TRACK IS
SIGNIFICANTLY DIFFERENT FROM PREVIOUS RUNS...AND ENSEMBLE MEMBERS
SHOW QUITE A BIT OF SPREAD.  HOWEVER THIS SYSTEM SHOULD BE COLDER
BRINGING ANOTHER SHOT OF SNOW ACROSS THE REGION FOR FRI NIGHT/SAT.
LITTLE CHANGES MADE TO PREVIOUS GRIDS.  -KT

...A WINTER STORM WATCH IS IN EFFECT FOR THE EASTERN SAN JUAN
MOUNTAINS AND THE LA GARITA MOUNTAINS FROM MONDAY EVENING THROUGH
TUESDAY NIGHT...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL...EAST
CENTRAL...SOUTH CENTRAL AND SOUTHEAST COLORADO.

.DAY ONE...TONIGHT

PERIODS OF LIGHT SNOW WILL CONTINUE TONIGHT OVER THE
CENTRAL AND SOUTHWEST MOUNTAINS. ADDITIONAL ACCUMULATIONS WILL
GENERALLY BE LESS THAN TWO INCHES. LOCAL AREAS OF LOW VISIBILITY
DUE TO BLOWING SNOW WILL CONTINUE TO RESULT IN POOR TRAVEL CONDITIONS.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

A MAJOR WINTER STORM WILL AFFECT SOUTHEASTERN COLORADO FROM LATE
MONDAY EVENING THROUGH EARLY THURSDAY. HEAVY SNOW WILL BEGIN
FALLING OVER THE SOUTHWEST MOUNTAINS LATE MONDAY...AND WILL
SPREAD TO THE EASTERN MOUNTAINS AND PLAINS BY TUESDAY MORNING.
SNOW ACCUMULATIONS OF GREATER THAN ONE FOOT ARE EXPECTED OVER THE
HIGHER ELEVATIONS OF THE SAN JUANS AND LA GARITA MOUNTAINS...INCLUDING
WOLF CREEK PASS.

SNOW ACCUMULATIONS OVER THE EASTERN MOUNTAINS AND INTERSTATE 25
CORRIDOR REMAIN UNCERTAIN. THE LATEST COMPUTER GUIDANCE SUGGESTS THAT
ONLY LIGHT TO MODERATE ACCUMULATIONS WILL OCCUR OVER THE
INTERSTATE METROPOLITAN AREAS...WITH GREATER ACCUMULATIONS
OCCURRING OVER THE SOUTHEASTERN PLAINS. HOWEVER...IF THE STORM SLOWS DOWN
SLIGHTLY...THEN MORE SIGNIFICANT ACCUMULATIONS COULD OCCUR CLOSER
TO THE MOUNTAINS. STAY TUNED FOR THE LATEST FORECASTS AND
ADVISORIES REGARDING THIS STORM.

.SPOTTER INFORMATION STATEMENT...

WEATHER SPOTTERS WILL NOT BE NEEDED TONIGHT.
