1103 AM MST SAT NOV 16 2013

.UPDATE...

&&

.SHORT TERM...THE NEXT BATCH OF SNOW IS SPREADING INTO THE
NORTHERN COLORADO MOUNTAINS AHEAD OF TONIGHTS TROUGH. RIDGETOP
WINDS ARE ALSO INCREASING WITH A LOW AMPLITUDE MOUNTAIN WAVE ON
THE EAST SLOPES...BUT THE STRONG WINDS HAVE GENERALLY BEEN ABOVE
9000 FEET SO FAR. AS THE RIDGETOP WINDS INCREASE...WE SHOULD SEE
AN INCREASE IN THE HIGHER FOOTHILLS THIS AFTERNOON. THEN THE SHEAR
INCREASES AND THE WAVE SHOULD DIMINISH THIS EVENING...COULD BE A
BIT OF A LULL IN THE FOOTHILLS BUT HOWLING UP HIGH. BUT BY LATE
TONIGHT THERE IS 80 KNOTS AT 500 MB AND 70 KNOTS AT 700
MB...MODELS PRODUCE A LOW AMPLITUDE WAVE WITH 95 KNOTS AT THE
RIDGETOP. SO BRUTE FORCE MAY WIN OUT LATER TONIGHT. STILL LOOKS
LIKE A BRIEF WINDOW OF OPPORTUNITY FOR AN AMPLIFIED WAVE BEHIND
THE TROUGH AXIS IN THE 09-15Z TIME FRAME AS STRONG WARM ADVECTION
ALOFT CREATES A GREAT TEMPERATURE PROFILE WITH STRONG SUBSIDENCE
AND SHEAR STARTING TO DECREASE. PROBABLY JUST A QUICK POP FOR OUR
CHINOOK HOT SPOTS LIKE ROCKY FLATS/BOULDER AND CARTER LAKE.
WITH A LACK OF COLD ADVECTION AND FAIRLY WESTERLY DIRECTION...NOT
FAVORABLE FOR FORT COLLINS. FOR BOULDER MAIN CONCERN IS THAT
LITTLE WINDOW IN THE MORNING...BUT SHOULD NOT BE WIDESPREAD OR
LONG LASTING. THREAT SEEMS TO SMALL FOR A WARNING FOR THOSE ZONES.
UPGRADING TO A HIGH WIND WARNING FOR THE FOOTHILLS...AND WILL GO
AHEAD AND KEEP ZONE 37 IN IT AS THE BRUTE FORCE MIXING MAY GET
INTO THE HIGHER ELEVATIONS LIKE FAIRPLAY. DELAYING THE START TO
03Z FIGURING THIS AFTERNOONS ACTION WILL NOT BE STRONG ENOUGH.

AS FOR THE SNOW...FORECAST LOOKING ON TRACK. SNOW AMOUNTS NOT HUGE
BUT LOTS OF WIND. I WILL ADD AN ADVISORY FOR ZONES 30 AND
32...NORTH AND MIDDLE PARKS...DUE TO THE AMOUNT OF WIND COMBINED
WITH SEVERAL INCHES OF SNOW.

&&

.AVIATION...VFR THROUGH TONIGHT. TREND WILL BE TOWARD MORE MIXING
OF WESTERLY WINDS THIS AFTERNOON...BUT WITH SOME MOUNTAIN WAVE
ACTIVITY TO THE WEST EXPECT THAT THERE WILL BE SOME STARTING AND
STOPPING. COULD BE SOME PERIODS APPROACHING CROSSWIND LIMITS AT
KDEN...BUT DO NOT EXPECT THOSE CONDITIONS TO PREVAIL. POSSIBLE
STRONGER WEST WINDS SOMETIME BETWEEN 09Z AND 18Z...ESPECIALLY AT
KBJC...BUT AGAIN EXPECT THOSE TO BE SOMEWHAT ERRATIC. CHANCE OF
SNOW SHOWERS WITH THE TROUGH AXIS TONIGHT 10 PERCENT OR LESS.

&&

.PREV DISCUSSION... /ISSUED 412 AM MST SAT NOV 16 2013/

SHORT TERM...AREAS OF LIGHT SNOW HAVE CONTINUED OVER THE
MOUNTAINS THIS MORNING WITH TRAFFIC CAMS ALONG I-70 SHOWING LIGHT
ACCUMULATIONS BETWEEN VAIL PASS AND THE EISENHOWER TUNNEL. THE WEB
CAM ON A SNOW STAKE AT COPPER MOUNTAIN SHOWS THAT 4-6 INCHES OF
SNOW HAS FALLEN SINCE 10 PM LAST NIGHT. SNOTEL SITES DO NOT BACK
UP THIS OBSERVATION THOUGH. SATELLITE IMAGERY SHOWS THAT THE
MOUNTAINS ARE IN A BIT OF A LULL NOW...AHEAD OF THE NEXT
DISTURBANCE WHICH WILL MOVE IN THIS AFTERNOON. THIS SYSTEM IS
BEING DRIVEN BY A 130+ KNOT JET STREAM. AS THE SYSTEM MOVES
IN...SNOW WILL INCREASE OVER THE MOUNTAINS AFTER THE LUNCH HOUR.
WINDS WILL ALSO BE INCREASING. BY EVENING...THE MOUNTAINS SHOULD
BE SEEING A FAIR AMOUNT OF BLOWING AND DRIFTING SNOW. WILL
CONTINUE THE WINTER WEATHER WARNING FOR ZONE 31 AND ADVISORIES FOR
ZONES 33 AND 34. AS THE UPPER JET APPROACHES...THE THREAT OF
STRONG WINDS WILL CONTINUE OVER THE EASTERN MOUNTAIN SLOPES. AT
TIMES THE VERTICAL SHEAR PROFILE WILL BE NEAR ZERO ON THE LEADING
EDGE OF THE JET STREAK. THE STRENGTH OF THE FLOW ALOFT LOOKS LIKE
IT WILL PRODUCE A HIGH WIND EVENT...BUT WILL HOLD ONTO THE HIGH
WIND WATCH FOR THE TIME BEING. ON THE PLAINS...CONDITIONS SHOULD
REMAIN DRY...BUT TEMPERATURES WILL BE COOLER DUE TO THE COLD
ADVECTION THAT WILL BE TAKING PLACE THROUGH THE NEXT 24 HOURS.
AREAS OF GUSTY WINDS SHOULD REMAIN CONFINED TO NEAR THE FOOTHILLS
DURING THE MORNING BUT THEN MAY SPREAD EASTWARD DURING THE
AFTERNOON DUE TO THE MIXING OF THE BOUNDARY LAYER THROUGH THE DAY.

LONG TERM...STG WNW FLOW ALOFT WILL BE OVER THE AREA SUN MORNING
AND THEN WEAKEN SOMEWHAT SUN AFTN INTO SUN NIGHT. CROSS-SECTIONS
SHOW MOISTURE DECREASING IN THE MTNS BY 18Z SUN SO SNOW SHOULD
GRADUALLY WIND DOWN BY LATE MORNING. HOWEVER WINDS WILL REMAIN
GUSTY THRU THE AFTN WITH AREAS OF BLOWING SNOW CONTINUING OVER THE
HIGHER PASSES SO WILL KEEP HIGHLIGHTS THRU 18Z.

AT LOWER ELEVATIONS THERE STILL WILL BE A FAVORABLE SET UP FOR HIGH
WINDS SUN MORNING AS STG DOWNWARD DESCENT COMBINES WITH A WK MTN
WAVE.  COMPONENT ALONG WINDS IN THE HIGHER FOOTHILLS AND MTN AREAS
ARE FCST AOB 90 KTS THRU SUN MORNING WITH SPEEDS IN THE 60-70 KT
RANGE IN AND NR THE LOWER FOOTHILLS.  BY MIDDAY WINDS SHOULD BEGIN
TO DECREASE BUT IT WILL REMAIN BLUSTERY.  OVER NERN CO THERE IS SOME
POTENTIAL FOR HIGH WINDS OVER THE PLAINS ALONG AND NORTH OF A
GREELEY TO FORT MORGAN TOP AKRON LINE AS WELL WHERE GUSTS FROM 55 TO
60 MPH MAY OCCUR THRU THE EARLY AFTN.  OUTSIDE OF THE WINDS IT WILL
BE DRY OVER NERN CO WITH AFTN HIGHS IN THE UPPER 40S TO LOWER 50S.

BY SUN EVENING THE WINDS WILL GRADUALLY DECREASE OVER THE PLAINS
ALTHOUGH IT WILL REMAIN WINDY IN THE MTNS AND NRN FOOTHILLS AS
COMPONENT ALONG WINDS ARE STILL IN THE 40-50 KT RANGE WITH A MTN
WAVE SHOWN OVERNIGHT INTO MON MORNING.  ON MON DRY WLY FLOW ALOFT
WILL BE OVER THE AREA WITH NO PRECIP EXPECTED.  A SFC LEE TROUGH
WILL DVLP OVER ERN CO WITH DOWNSLOPE LOW LVL FLOW THUS SHOULD SEE
WARMER TEMPS OVER NERN CO WITH HIGHS IN THE UPPER 50S TO POSSIBLY
NEAR 60.

FOR TUE LITTLE CHANGE EXPECTED AS THE FLOW ALOFT REMAINS WLY
ALTHOUGH MAY SEE AN INCREASE IN HIGHER LEVEL CLOUD COVER.  WITH WLY
LOW LVL WINDS GOOD DOWNSLOPE COMPONENT WILL BE IN PLACE WHICH MAY
ALLOW FOR HIGHS TO RISE INTO THE LOWER TO MID 60S OVER NERN CO.  BY
WED MOISTURE WILL INCREASE IN THE ZONAL FLOW ALOFT WHICH MAY LEAD TO
A CHC OF -SHSN IN THE MTNS.  OVER NERN CO CO IT WILL REMAIN DRY WITH
TEMPS STILL ABV NORMAL.

BY LATER IN THE WEEK THE ECMWF AND GFS BEGIN TO DIVERGE WITH REGARDS
TO THE UPPER AIR PTRN.  THE ECMWF DEVELOPS AN UPPER LEVEL LOW OVER
CALIFORNIA ON THU WITH SWLY FLOW ALOFT OVER NRN CO WHILE THE GFS HAS
A DIFFUSE UPPER LEVEL TROUGH OVER THE GREAT BASIN.  MEANWHILE AT THE
SFC BOTH MODELS DO AGREE THAT A RATHER STG CDFNT WILL MOVE INTO NERN
CO BY THU WITH MUCH COOLER TEMPS.  OVERALL WILL MENTION A CHC OF
SNOW IN THE MTNS AND KEEP LOW POPS IN OVER NERN CO FOR WED NIGHT
THRU THU.

FOR FRI THE GFS SHOWS A WEAK UPPER LEVEL TROUGH MOVING ACROSS WITH
MOST OF THE ENERGY TRACKING ACROSS THE SRN ROCKIES.  MEANWHILE THE
ECMWF STILL HAS A CLOSED UPPER LEVEL OVER THE SWRN US WITH SWLY FLOW
ACROSS THE AREA.  HOWEVER BOTH MODELS DO SHOW COLD SFC HIGH PRES
REMAINING OVER THE AREA.  AT THIS TIME WILL JUST MENTION LOW POPS
FOR FRI AND KEEP TEMPS GENERALLY 15 DEGREES BLO NORMAL OVER NERN
CO.

AVIATION...CEILINGS AND VISIBILITIES ARE NOW EXPECTED TO REMAIN
BETWEEN HIGH AND UNLIMITED AS STRONG WESTERLY FLOW ALOFT WILL
PRODUCE DOWNSLOPE DRYING ACROSS THE DENVER METRO ARE THROUGH THE
DAY. THE LOWEST CEILINGS SHOULD BE DURING THE LATE AFTERNOON AND
EVENING...BUT SHOULD REMAIN ABOVE 7000 FEET AGL. WEST WINDS MAY BE
THE MAIN CONCERN THROUGH THE NEXT 24 HOURS AS STRONG WINDS ARE
EXPECTED IN AND NEAR THE FOOTHILLS. GUSTY WEST WINDS MAY SPREAD
ACROSS THE METRO AREA DURING THE AFTERNOON AND EVENING WITH GUSTS
UP TO 30 MPH POSSIBLE. WITH THE STRONG WEST WINDS OVER THE
MOUNTAINS...PRECIPITATION IS NOT LIKELY TO MAKE IT OUT TO
KDEN...BUT A ROGUE SHOWER CAN NOT BE RULED OUT. AIR TRAFFIC
HEADING OVER THE MOUNTAINS SHOULD BE PREPARED FOR A BUMPY RIDE
THROUGH THE NEXT 24 HOURS.

WEATHER DISTURBANCE. SNOWFALL AMOUNTS UP TO 6 INCHES WILL BE

INCHES OF SNOW EXPECTED OVERNIGHT. THE INCREASING WINDS WILL

VISIBILITIES. EAST OF THE CONTINENTAL DIVIDE AND OVER THE FRONT
RANGE FOOTHILLS...LESS SNOW IS EXPECTED...BUT VERY STRONG WINDS
WILL BE POSSIBLE. WIND GUSTS OF 50 TO 70 MPH MAY MAKE TRAVEL
