WESTERN COLORADO & EASTERN UTAH AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
130 PM MST SAT NOV 24 2001
THANK YOU TO SLC AND PUB FOR COORDINATION.
CURRENTLY: BAROCLINIC LEAF IN STRONG WARM ADVECTION/SW FLOW IS
SPREADING INTO UTAH...AND WILL BE INTO COLORADO BY 00Z. KGJX VAD
WIND PROFILE HAS INCREASED TO 50KT WITH KICX TO 95KT AT JET LEVEL.
MODELS IN GOOD AGREEMENT...AVN THE MOST CONSISTENT AND DEEPER AND
ETA IS FASTER. BOTH YIELD THE SAME FORECAST: ANOTHER TASTE OF
WINTER.
TONIGHT-SUNDAY: SNOW TO START IN THE SOUTHERN MTNS SOON AFTER SUNSET
AND INCREASE TOWARDS MORNING. OROGRAPHIC SNOW MODEL YIELDS WARNING
CRITERIA...AND JET DYNAMICS/CONVECTION WILL ADD TO THOSE AMOUNTS ON
SUNDAY. FRONTAL PASSAGE LOOKS PIECEMEAL WITH COLD ADVECTION
BEGINNING BEFORE 12Z BUT STRONGER FRONT AROUND 18Z FOR GJT. EXPECT
THE CENTRAL VALLEYS TO SEE THEIR BEST CHANCE OF SNOW AFTER 12Z IN THE
COLD AIR. WINDS DIMINISH IN THE TROF...BUT WITH GREATER MIXING WINDS
WILL CONTINUE TO BE A FACTOR. 7-5 LAPSE RATE GOES TO 8+ IN THE
AFTERNOON FOR THE SOUTH AND CENTRAL FOR ISOLATED THUNDERSNOW. 8-7
THICKNESS LESS THAN 1550 WOULD LOWER ACCUMULATION LEVEL TO VALLEY
FLOORS. NORTHERN MTNS MISS MOST OF THE DYNAMICS BUT WILL DO WELL IN
COLD NW FLOW.
SUNDAY NIGHT: LOSS OF SUPPORT SOUTH SHOULD LIMIT SNOW TO
OROGRAPHIC FAVORED AREAS SUCH AS TEX-OURAY-LAKE CITY AND END IT OVER
THE SOUTHERN VALLEYS. NORTHERN MTNS MOIST NW FLOW OF 20-30KTS
WILL CONTINUE TO ACCUMULATE.
MONDAY-MONDAY NIGHT: COLD NW FLOW CONTINUES FOR LIGHT ACCUMULATIONS
IN THE NORTH...AND CENTRAL MTNS. IN HIGHLY AMPLIFIED FLOW THE COLD
CORE IS NOW PROGGED TO BE EAST OF THE CWA. STILL CLEARING SKIES
AND CALM WINDS WILL YIELD VERY COLD MORNING TEMPS. 99/RAMEY
EXTENDED: (TUE-SAT)...BROAD TROUGH OVER THE ROCKIES AND NORTHERN
PLAINS WILL GRADUALLY BEGIN TO SHIFT EAST TUESDAY AS THE UPPER LOW
PROGRESSES THROUGH THE UPPER MIDWEST. NORTHWEST FLOW WILL CONTINUE TO
PRODUCE PERSISTENT SHOWERS OVER THE NORTHERN CWFA THROUGH WEDNESDAY.
WEAK SHORTWAVES RIDING THROUGH NORTHWEST FLOW WILL CARVE THE TROUGH
OVER THE MIDWEST BY THURSDAY. THIS WILL HELP TO DRY THINGS OUT ON
THURSDAY AS ALL MODELS AGREE ON WEAK RIDGE OVER CWFA. HOWEVER...
RESPITE WILL BE SHORT AS PROGRESSIVE WESTERLY FLOW OFF THE PACIFIC
RETURNS FOR FRIDAY AND SATURDAY. SERIES OF WAVES IN THIS FLOW AND
INCREASING MOISTURE WILL NECESSITATE POPS AGAIN FOR FRIDAY AND
SATURDAY. TEMP GUIDANCE LOOKS A LITTLE COLD...BUT NONETHELESS WENT
AHEAD AND NUDGED TEMPS DOWN A CATEGORY OR SO FOR TUESDAY AND
WEDNESDAY. CNJ
