AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
455 AM MST WED FEB 16 2011

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT

STRONG WINDS AND SNOW WILL HIT THE MOUNTAINS DURING THIS PERIOD...
WITH RAIN AND SNOW FOR THE CENTRAL AND SOUTHERN VALLEYS NUMEROUS
WIND AND WINTER HIGHLIGHTS ARE IN EFFECT.

A PACIFIC STORM ALONG THE WEST COAST EARLY THIS MORNING WILL EJECT A
SHORTWAVE ACROSS THE GREAT BASIN AND NORTHERN ROCKIES TONIGHT AND
THURSDAY...WHILE THE MAIN UPPER TROUGH RELOADS AND REMAINS ALONG THE
WEST COAST. A COLD FRONT WITH LIMITED MOISTURE MOVES INTO NE UT/NW CO
AFTER MIDNIGHT TONIGHT...THEN SLOWS OR STALLS ACROSS SE UT AND WEST-
CENTRAL CO ON THU AS THE UPPER DISTURBANCE AND SFC LOW MOVE ACROSS
WY/MT/DAKOTAS.

SW WINDS STRENGTHEN AHEAD OF THIS SYSTEM IN A WARM ADVECTIVE PATTERN
TODAY. 700 MB WINDS FORECAST TO REACH 45-60 KTS ACROSS ERN UT AND NW
CO BY THIS EVENING...AS A 120-130 KT UPPER JET SETS UP FROM SRN UT
TO NW CO. HIGH WIND WARNING FOR GUSTS 75 MPH FOR THE MTNS IN ERN UT
AND NW CO LOOKS ON TRACK. BELIEVE ENOUGH MIXING COMBINED WITH A
TIGHTENING PRESSURE GRADIENT WILL RESULT GUSTIER WINDS SE UT AND NW
CO VALLEYS THIS AFTERNOON AND EVENING THAN MOS GUIDANCE PREDICTS...SO
WILL ISSUE A WIND ADVISORY THIS AFTERNOON/EVENING FOR GUSTS 45 MPH
FOR UT ZONES 27/29/22 AND CO ZONES 1/2. THINK THE GRAND VALLEY AND
ESPECIALLY THE ERN UINTA BASIN WILL NOT SEE QUITE AS STRONG. MODELS
SHOWING LESS WIND FROM VAIL/ASPEN TO THE SAN JUAN MTNS AND WILL
DOWNGRADE THE HIGH WIND WARNING THERE TO A WIND ADVISORY.

THE UPPER JET SHIFTS TO SW CO LATER TONIGHT AS THE COLD FRONT MOVES
INTO THE NORTH. GOOD FRONTAL UPLIFT AND OROGRAPHIC FORCING WILL
BRING SNOW TO THE NORTH LATER TONIGHT INTO THU. WINDS TURN MORE
WESTERLY WHICH WILL FAVOR SNOW ACCUMS IN THE STEAMBOAT VALLEY.
UPGRADED THE WATCH TO A WINTER STORM WARNING FOR THE ELKHEAD/PARK/
FLATTOPS AREAS...AND TO A SNOW/BLOWING SNOW ADVISORY FOR THE ELK MTNS
AROUND ASPEN AND VAIL...STEAMBOAT VALLEY...AND FOR THE EASTERN UINTA
MTNS. THE TAVAPUTS AND ROAN PLATEAUS LOOK SHY OF ADVISORY SNOW
AMOUNTS...BUT PERIODS OF SNOW/BLOWING SNOW WILL STILL CAUSE PROBLEMS
FOR DOUGLAS PASS EARLY THU MORNING. WILL ALSO HAVE TO KEEP AN EYE ON
THE NW CO VALLEYS WHERE OVERRUNNING COULD RESULT IN GREATER SNOW
ACCUMS...AND WIND FOR BLOWING SNOW.

00Z MODELS WERE RATHER STINGY WITH SNOW ACCUMS FOR THE SOUTHERN
MTNS...HOWEVER...WHERE SNOW LEVELS MAY START OFF 8000 FT OR
HIGHER THIS EVENING BEFORE LOWERING BY THU. BUT...EXPECT WIND WILL
BE PREVALENT WITH THE UPPER JET OVERHEAD THROUGH THU. GUSTS OVER 70
MPH EXPECTED ABOVE 10K FEET. THUS...DECIDED TO UPGRADE THE BLIZZARD
WATCH TO A BLIZZARD WARNING FOR LATE TONIGHT THROUGH THU EVENING.
PEAK TIME FOR SNOW/WIND IN THE BLIZZARD WARNING LOOKS LIKE 300 AM TO
ABOUT NOON THU.

WEATHER WINDS DOWN THU NIGHT.

THANKS TO SLC/BOU/CYS/PUB FOR THE COORDINATION!

.LONG TERM...FRIDAY THROUGH TUESDAY...
UNSETTLED WEATHER WILL CONTINUE THIS WEEKEND AS A MEAN UPPER LEVEL
TROUGH REMAINS OVER THE EASTERN PACIFIC DURING THE LATTER PART OF
THE WORK WEEK. NAM...GFS AND ECMWF WERE IN GOOD AGREEMENT EARLY ON
THOUGH SOLUTIONS DIVERGE THIS WEEKEND WITH RESPECT TO PROPAGATION OF
A DEEP SHORTWAVE ACROSS THE WEST. HPC DISCUSSED A FAIRLY WIDE SPREAD
IN ENSEMBLE SOLUTIONS ACROSS THE WEST DURING THE PERIOD...SO FORECAST
CONFIDENCE NOT GREAT THIS MORNING. CONSEQUENTLY...WILL ABSTAIN FROM
MAKING ANY SIGNIFICANT CHANGES TO THE GOING FORECAST.

FRIDAY-FRIDAY NIGHT: FLOW BACKS TO THE SOUTHWEST FRIDAY AS THE UPPER
LEVEL TROUGH OVER THE EASTERN PACIFIC DEEPENS. LIFT NEGLIGIBLE
BENEATH WEAK SHORTWAVE RIDGE ALOFT AND MOISTURE LIMITED SO EXCEPT
FOR THE POSSIBILITY OF SOME LIGHT SHOWERS OVER HIGHER TERRAIN...
EXPECT MAINLY DRY WEATHER. DESPITE WARM AIR ADVECTION...DOUBTFUL
THERE WILL BE ENOUGH WIND ALOFT TO MIX WARMER AIR INTO THE VALLEYS
AND TEMPERATURES LIKELY TO ONLY REACH NORMAL LEVELS DURING THE
AFTERNOON...THOUGH INCREASING CLOUDS SHOULD HELP BUOY OVERNIGHT
LOWS.

SATURDAY-SUNDAY: WEATHER BECOMES MORE ACTIVE THIS WEEKEND AS THE
DEEP EASTERN PACIFIC TROUGH BEGINS TO MOVE INLAND ON SATURDAY. IN
RESPONSE...FLOW BECOMES MORE SOUTHERLY AND INCREASES AT RIDGE TOP
LEVEL DURING THE DAY. IMPRESSIVE DIFFLUENCE AND DIVERGENCE ALOFT
INDICATED WHILE SURGE OF DEEPER PACIFIC MOISTURE MAKES ITS WAY INTO
THE REGION. CONSEQUENTLY...EXPECT WIDESPREAD PRECIPITATION TO DEVELOP
SATURDAY...FAVORING THE SOUTH. CONTINUED WAA PROMISES TO RAISE
SNOWLEVELS ABOVE MOST VALLEY LOCATIONS...EVEN INTO SATURDAY NIGHT. EC
AND GFS BEGIN TO DIVERGE FAIRLY SIGNIFICANTLY SATURDAY NIGHT AS MUCH
MORE PROGRESSIVE GFS CARRIES THE UPPER LEVEL TROUGH AXIS OVER THE
CWFA BY SUNDAY MORNING WHILE THE EC HOLDS A MORE VERTICALLY STACKED
SYSTEM OVER THE GREAT BASIN. DESPITE MODEL DIFFERENCES...BOTH
INDICATED WIDESPREAD PRECIPITATION LIKELY TO CONTINUE INTO SUNDAY.

MONDAY-TUESDAY: THE NEXT LOW DEVELOPS OFF THE COAST LATE MONDAY INTO
TUESDAY. MODELS KEEP THIS FEATURE UPSTREAM THROUGH THE END OF THE
PERIOD...BUT THE STRONG AND MOIST SOUTHWEST FLOW WILL CONTINUE TO
KEEP CONDITIONS UNSETTLED.

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL ACROSS MOST OF THE REGION THIS MORNING...
HOWEVER LOCAL HAZE OR FOG IN THE UINTAH BASIN WILL BRING MVFR VSBY
THROUGH MIDDAY. EXPECT GUSTY SOUTHWEST WINDS TO DEVELOP AROUND NOON
...ESPECIALLY ALONG 125 NM WIDE CORRIDOR CENTERED ON A KPGA TO 30W
KRWL LINE. RIDGE TOP WINDS WITHIN THIS CORRIDOR WILL FREQUENTLY GUST
IN EXCESS OF 50 MPH AND OCCASIONALLY ABOVE 75 MPH THIS AFTERNOON AND
EVENING. IN ADDITION...SCATTERED SNOW SHOWERS WILL DEVELOP OVER THE
SOUTHERN MOUNTAINS WHICH WILL PRODUCE OCCASIONAL MVFR CIGS AND VSBY
IN SNOW AND BLOWING SNOW. CONDITIONS DETERIORATE FURTHER TONIGHT AS
SNOW BECOMES WIDESPREAD WITH MVFR FLIGHT CATEGORIES BECOMING THE
NORMAL AND IFR/LIFR CONDITIONS COMMON DUE TO SNOW AND BLOWING SNOW.
