AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
239 PM MDT THU APR 28 2011

.SHORT TERM...TONIGHT THROUGH SUNDAY...
ACTIVE WEEKEND IN THE WORKS WITH RAIN...SNOW...WIND...FREEZING TEMPS
AND FIRE CONCERNS ALL THROWN IN THE MIX.  REMAINDER OF TODAY WILL
SEE THE WARM-UP CONTINUING WITH MOSTLY SUNNY SKIES ACROSS UTAH AND
COLORADO.

TONIGHT AND EARLY TOMORROW MORNING...A STRONG COLD FRONT AND ASSOD
UPPER LEVEL TROF WILL APPROACH FROM THE NW INCREASING PRECIP CHANCES
FOR EXTREME NERN UT INTO NW CO WHILE ALSO TIGHTENING UP THE PRESSURE
GRADIENT.  FORECAST SKEW-T DATA...H7 WINDS...ALL CORROBORATE NICELY
WITH SOME STRONGER WINDS MIXING DOWN TO THE SFC WITH WINDS PICKING
UP IN SPEED LATE FRI MORNING INTO THE AFTN.  HIGHEST WIND SPEEDS ARE
EXPECTED ALONG AND JUST BEHIND THE COLD FRONT WHICH WILL START
MOVING THRU EARLY FRI MORNING AND HAVE PUSHED THRU ENTIRE CWA BY
FRI EVENING.  HELD OFF ON ISSUING WIND ADVISORY SINCE BELIEVE SPEEDS
WILL BE JUST BELOW CRITERIA BUT THAT BEING SAID...THEY WILL STILL
NEED TO BE MONITORED AND WINDY CONDITIONS WILL BE THE NORM ACROSS
THE REGION.  THESE WINDS HAVE ALSO INCREASED FIRE WX CONCERNED AS
DESCRIBED IN FIRE SECTION BELOW.

AS THE FRONT MOVES THROUGH...PRECIP CHANCES WILL PICK UP N OF I-70
WITH BEST CHANCES OVER NRN MTNS...AND THEN TRANSLATING SWRD TO CENT
MTNS BY EARLY AFTN.  NAM12/GFS40 CONTINUE TO HIGHLIGHT ACCUMULATING
SNOW FOR THOSE AREAS AND THE LATEST RUN IS NO DIFFERENT.  AM
EXPECTING 4 TO 8 INCHES OF NEW SNOW FOR NRN/CENT MTNS FROM FRIDAY
MORNING THRU NOON SATURDAY.  SNOW LEVELS WILL START NEAR 8000FT
FRIDAY MORNING AND THEN DROP TO MTN BASES AFTER FROPA.  AS USUAL...
NWLY WINDFLOW AFTER FRONTAL PASSAGE WILL KEEP SNOW GOING FOR NRN/CENT
MTNS THRU SATURDAY MORNING.  FOR THOSE TRAVELLING OVER MOUNTAIN
PASSES FOR THE WEEKEND...HAZARDOUS CONDITIONS CAN BE EXPECTED WITH
SNOW AND ICE.  FOR THESE REASONS...ISSUED LOW-END ADVISORY FOR
SNOW AMOUNTS FOR THOSE CO ZONES 4 10 12 13.  MODELS CONTINUE TO
HIGHLIGHT BULK OF MOISTURE TO FALL IN AND AROUND CONTINENTAL DIVIDE
AS PREVIOUSLY DISCUSSED WITH MORE SHOWERY TYPE PRECIP ALONG/BEHIND
FRONT SO FORECAST FOLLOWS SUIT.  AS THE FRONT MOVES THRU...SHOWERS
WILL INCREASE AS WILL SURFACE WINDS BUT IT WILL BE SHORT-LIVED AS
POWERFUL OVERHEAD JET QUICKLY PUSHES SYSTEM TO THE E. SOME DECENT
FRONTOGENETICAL FORCING SHOWING UP ALONG WITH DIVERGENCE ALOFT BUT
RAPIDLY WEAKENS AND PERSISTS FOR SUCH A SHORT TIME...WENT AHEAD AND
DROPPED POP/QPF AND AREAL COVERAGE FOR AREAS W OF THE MTNS.

FOR FRI NIGHT/SAT MORNING....CLEARING CONDITIONS FROM W TO E AND
STRONG H7 CAA OF -10 TO -12C...EXCEPT MTNS WHICH WILL STAY UNDER
CLOUD COVER...WILL ALLOW ANOTHER NIGHT OF SUB-FREEZING TEMPS
PROMPTING ISSUANCE OF FREEZE WATCH FOR CO ZONES 6 7 11 21.

NAM12 DEPICTS AXIS OF UPPER LEVEL TROF FIRMLY ENTRENCHED OVER CWA
SAT MORNING WITHOUT MUCH MOVEMENT THRU SAT NIGHT.  VERY LOW MOISTURE
CONTENT AND INCREASING STABILITY WILL KEEP PRECIP TO A MINIMUM
THOUGH LINGERING CLOUDS CAN BE EXPECTED FOR MUCH OF THE AREA.  MODELS
ARE NOW HINTING AT UPPER LEVEL TROF BECOMING CLOSED LOW EARLY SUNDAY
MORNING AS INVERTED TROF APPROACHES FROM THE EAST BRINGING A CHANCE
FOR PRECIP OVER PAGOSA SPRINGS AND SAN JUANS.  WILL BE INTERESTING TO
SEE HOW THIS PLAYS OUT SINCE RETROGRADING WAVES ARE SOMEWHAT UNCOMMON
THOUGH NOT UNHEARD OF.

TEMPS WILL BOUNCE AROUND OVER THE WEEKEND WITH NORMAL TEMPS THRU
TOMORROW...DROPPING ANOTHER 20 DEG OR SO FOR MOST PLACES SATURDAY
AFTER THE FRONT PASSES BEFORE REBOUNDING ABOUT 10 DEG PER DAY THRU
REMAINDER OF SHORT-TERM.

.LONG TERM...SUNDAY NIGHT THROUGH THURSDAY...

THE MODEL TREND IS TO SLOW THE EVOLUTION TO A MORE BENIGN PATTERN IN
THE WAKE OF THIS WEEKENDS LOW PRESSURE TROUGH. THE 12Z RUNS KEEP
SOME SHOWERS ALONG THE DIVIDE IN THE NORTHWEST FLOW THROUGH SUNDAY
NIGHT. THEREFORE UPPED POPS A LITTLE ON THE FAVORED NORTH-FACING
SLOPES. ANY SHOWERS WILL PROBABLY BE ON THE LIGHT SIDE...
DIMINISHING LATE SUNDAY NIGHT. TEMPERATURES WILL REMAIN WELL BELOW
NORMAL INTO MONDAY...POSSIBLY DROPPING BELOW FREEZING IN THE CENTRAL
AND SOUTHERN VALLEYS MONDAY MORNING.

THEN BY TUESDAY...DRIER AND WARMER CONDITIONS ARE EXPECTED AS THE
STORM TRACK SHIFTS TO THE NORTH. AS SHORTWAVES PASS ACROSS THE
NORTHERN TIER STATES...WINDS WILL INCREASE ACROSS OUR AREA AT
TIMES...BUT WITH LOW CONFIDENCE IT LOOKS LIKE PRECIPITATION WILL
GENERALLY STAY TO THE NORTH. MODELS CONTINUE TO SHOW SOME DIFFERENCES
IN THE TIMING AND TRACK. THE ECMWF BRINGS A SHORTWAVE ACROSS THE
NORTH DURING THE TUE NIGHT-WED TIME FRAME. WHILE THE 12Z RUN IS MORE
NORTHERLY THAN THE 00Z EC...IT STILL INDICATES SHOWERS WILL SPREAD
INTO THE SOUTHERN MOUNTAINS. THE CANADIAN ALSO SHOWS A SHARPER AND
MORE SOUTHERLY TROUGH UPSTREAM AT 144 HOURS/12Z WED. BUT THE GFS
KEEPS THE ACTIVITY NORTH OF THE AREA. FOR THIS PACKAGE...I DID NOT
CHANGE THE VERY LOW POPS OVER THE NORTH. WILL WAIT FOR BETTER
CONSISTENCY TO SEE IF HIGHER POPS ARE WARRANTED.

&&

.AVIATION...

FOR TONIGHT...VFR CONDITIONS WILL PREVAIL...WITH SOUTHWEST WINDS
INCREASING OVER THE HIGHER MOUNTAINS OVERNIGHT. BY FRIDAY SHOWERS
WILL SPREAD IN FROM THE NORTH AS A COLD FRONT BEARS DOWN ON THE AREA
FROM THE NORTHWEST. IN ADDITION...SOUTHWEST WINDS WILL STRENGTHEN AND
MIX INTO THE VALLEYS. THESE WINDS MAY PRODUCE WIND SHEAR AND/OR
TURBULENT MIXING. AND AT TIMES MVFR OR EVEN IFR CIGS AND/OR VSBYS
WILL DEVELOP IN VALLEY RAIN OR MOUNTAIN SNOW SHOWERS...MAINLY OVER
THE CENTRAL MOUNTAINS AND NORTH. THE SOUTH...AND THE WESTERN VALLEYS
WILL GENERALLY REMAIN DRY WITH VFR CONDITIONS.

&&

.FIRE WEATHER...
ABOVE-MENTIONED COLD FRONT WILL BRING PERIOD OF SUSTAINED WINDS
ABOVE 25 MPH FRI AFTN ALONG WITH RH VALUES HOVERING AT OR BELOW 15%.
THOUGH RECENT RAIN AND SNOW FOR ZONE 207 HAVE KEPT CONDITIONS
SOMEWHAT WET...THESE WX CONDITIONS MAY STILL CAUSE EXPLOSIVE FIRE
GROWTH.  FOR THESE REASONS...A RED FLAG WARNING HAS BEEN ISSUED
FOR WATCH FOR CO FIRE ZONE 207 VALID FROM 11AM TO 6PM FRIDAY.
