AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
352 AM MDT FRI OCT 29 2010

.SHORT TERM...A WRINKLE ON AN OTHERWISE GORGEOUS FALL DAY AS THE
COMBINATION OF SOME HIGH LEVEL MOISTURE AND A WEAK MOUNTAIN WAVE IS
PRODUCING A FAIRLY SUBSTANTIAL WAVE CLOUD OVER THE FRONT RANGE. NOT
MUCH SIGN OF THIS CHANGING...PERHAPS A BIT OF A DECREASE IN MOISTURE
DURING THE DAY AND THEN AN INCREASE AGAIN TONIGHT WITH NO CLEAR SIGN
OF THE WAVE STRUCTURE CHANGING. STRONG LOW LEVEL INVERSION IS ONCE
AGAIN KEEPING ALL THE WIND ABOVE 10 THOUSAND FEET...AND WHILE THE
LOW LEVELS WILL BE A LITTLE WARMER TODAY THERE WILL STILL BE
RESISTANCE TO MIXING...ESPECIALLY WITH SOME CLOUD COVER THAT MAY
TAKE A COUPLE DEGREES OFF TODAYS HIGHS. MOS GUIDANCE SEEMS
UNREASONABLY WARM TODAY GIVEN THE LACK OF WIND AND LIMITED
SUNSHINE...I DROPPED THE FORECAST HIGHS A DEGREE OR TWO. WITH THE
LOW LEVEL STABILITY...SOME QUESTION ABOUT WIND DIRECTION AROUND
DENVER. STILL THINK WESTERLY DIRECTIONS WILL PREVAIL NEAR THE
MOUNTAINS WITH CONVERGENCE INTO EASTERLY OR JUST LIGHT WINDS AT
LOWER ELEVATIONS ON THE PLAINS...BUT SPEEDS IN THE WESTERLIES WILL
PROBABLY BE LIGHT TOO. RAISED TEMPS A LITTLE AGAIN TONIGHT WITH SOME
CLOUD COVER...ONCE AGAIN THE PATTERN OF MILDER TEMPS IN AREAS WITH
DRAINAGE WINDS AND COLD POCKETS...THOUGH MITIGATED BY SOME CLOUDS.

.LONG TERM...FAIRLY STRONG SOUTHWESTERLY FLOW ALOFT IS PROGGED
SATURDAY AND MUCH OF SATURDAY NIGHT...WITH A WEAK UPPER TROUGH TO
MOVE ACROSS ALL OF COLORADO BY MID MORNING SUNDAY.  PRETTY STRONG
ZONAL FLOW ALOFT IS INDICATED SUNDAY AND MUCH OF SUNDAY NIGHT...WITH
ANOTHER UPPER TROUGH MOVING INTO WESTERN COLORADO BY 12Z MONDAY
MORNING.  UPWARD VERTICAL VELOCITY IS EXPECTED SATURDAY AND SATURDAY
NIGHT...WITH DOWNWARD MOTION ON SUNDAY.  WEAK UPWARD MOTION RETURNS
LATE SUNDAY NIGHT INTO MONDAY MORNING...BUT WEAKER THAN SATURDAY'S
ENERGY.  THE LOW LEVEL PRESSURE AN WIND FIELDS INDICATED WEAK
BOUNDARY LAYER FLOW EARLY SATURDAY...WITH EAST-SOUTHEASTERLIES OUT
ON THE PLAINS LATER SATURDAY AND SATURDAY EVENING.  THERE IS SOME
DOWNSLOPING FLOW LATE SATURDAY NIGHT INTO EARLY SUNDAY AFTER THE
UPPER FEATURE MOVES ACROSS.  CROSS SECTIONS DO HAVE A MOUNTAIN TOP
STABLE LAYER IN PLACE THEN...BUT IT HAS WEAKENED SOME FROM
YESTERDAY'S 00Z RUNS.  THE LOW LEVEL WINDS LOOK PRETTY WEAK AGAIN
BY MID DAY SUNDAY THROUGH LATE SUNDAY NIGHT...THEN BETTER LOOKING
NORTHWESTERLY DOWNSLOPING IS PROGGED BY MONDAY MORNING WITH THE NEXT
UPPER TROUGH PASSAGE.  FOR MOISTURE...THERE IS SOME TO MOVE INTO THE
WESTERN FORECAST AREA BY LATE DAY SATURDAY.  THERE IS FAIRLY DECENT
MOISTURE FOR SATURDAY NIGHT...BUT IT IS A QUICK SHOT.  ON SUNDAY...
THE GFS HAS A BIT MORE MOISTURE OVER THE FORECAST AREA COMPARED TO
THE NAM.  BY SUNDAY NIGHT...BOTH MODELS SHOW PRETTY DECENT MOISTURE
FOR THE FORECAST AREA.  OVER THE EAST IT IS IN THE MID AND UPPER
LEVELS ONLY.  THE QPF FIELDS HAVE SOME MEASURABLE PRECIPITATION OVER
THE MOUNTAINS SATURDAY NIGHT...MORE THAN YESTERDAY'S 00Z RUNS
INDICATED.  THERE IS EVEN A TAD OVER THE NORTHERN BORDER AREAS OF
THE PLAINS.  THE GFS HAS A BIT OVER THE NORTHERN HALF OF THE
MOUNTAINS SUNDAY.  THERE IS A TINY BIT OVER THE MOUNTAINS SUNDAY
NIGHT.  FOR POPS...MOISTURE IS PRETTY GOOD FOR ABOUT A 6 HOUR PERIOD
IN THE MOUNTAINS SATURDAY NIGHT.  HOWEVER...MOUNTAIN TOP FLOW IS
PROGGED TO BE SOUTHWESTERLY DURING THE BEST MOISTURE SO WILL GO
WITH...20-40% POPS THERE.  NOT MUCH OROGRAPHIC HELP.  THE PLAINS ARE
TOO DRY FOR ANY POPS.  WILL KEEP MINOR POPS GOING SUNDAY FOR THE
HIGH MOUNTAINS.  WILL GO WITH 10-20% POPS IN THE MOUNTAINS WITH THE
NEXT SYSTEM.  AGAIN...THE PLAINS LOOK TOO DRY FOR ANY POPS.  FOR
TEMPERATURES...SATURDAY'S HIGHS ARE SIMILAR TO TODAY'S HIGHS.
SUNDAY'S HIGHS COOL OFF 3.5-6.0 C FROM SATURDAY'S.  FOR THE LATER
DAYS...MONDAY THROUGH THURSDAY...MODELS HAVE STRONG NORTHERLY FLOW
ALOFT FOR THE FORECAST AREA MONDAY AND MONDAY NIGHT.  A SIGNIFICANT
UPPER RIDGE IS PROGGED OVER COLORADO THROUGH THURSDAY.  THE FLOW
ALOFT WEAKENS BY TUESDAY AS IS NORTH-NORTHEASTERLY.  BY WEDNESDAY
NIGHT AND THURSDAY IT IS WEAK AND NORTHWESTERLY.  THERE IS A BIT OF
MOISTURE MONDAY...ENOUGH FOR MINOR ALPINE POPS...OTHERWISE ALL THE
FORECAST AREA IS DRY THROUGHOUT.  TEMPERATURES ARE CLOSE TO SEASONAL
NORMALS ON MONDAY...THEN THEY ARE ABOVE NORMALS TUESDAY THROUGH
THURSDAY.

.AVIATION...VFR CONDITIONS WILL CONTINUE THROUGH TONIGHT. SOME
QUESTIONS ABOUT WIND DIRECTION THIS AFTERNOON...AND IT MAY BE
VARIABLE...BUT SPEEDS WILL BE LESS THAN 10 KNOTS.

.BOU WATCHES/WARNINGS/ADVISORIES...NONE.
