AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
300 PM MDT SAT SEP 4 2010

.SHORT TERM...UPPER TROUGH APPROACHES SUNDAY WITH A VERY DRY AIRMASS
OVER OUR AREA. ONLY SLIGHT WARMING ANTICIPATED AND NOW ONLY A LITTLE
MORE WIND AS WELL...BUT IT LOOKS TO BE EVEN DRIER ON SUNDAY DRIVING
AFTERNOON HUMIDITIES INTO THE SINGLE DIGITS. CERTAINLY HOT AND DRY
ENOUGH TO JUSTIFY A RED FLAG WARNING...WINDS MORE MARGINAL BUT WITH
THE EXPECTATION THAT THEY WILL BE A BIT MORE THAN TODAY WE SHOULD
SEE 25 MPH GUSTS IN THE MOUNTAINS AND ON THE ADJACENT PLAINS. WE ARE
UPGRADING THE FIRE WEATHER WATCH TO A RED FLAG WARNING AND BEGINNING
IT AT 10 AM SUNDAY AS IT SHOULD GET HOT/DRY/BREEZY FAIRLY EARLY IN
THE DAY...MOS GUIDANCE HAS 90 DEGREES WITH SINGLE DIGIT HUMIDITIES
IN DENVER BY NOON. DROPPED SOUTH PARK AS FUELS ARE REPORTED TO NOT
BE DRY ENOUGH YET...MODERATE FIRE DANGER THERE YESTERDAY WILL BE
INCREASING OF COURSE. FURTHER EAST ON THE PLAINS THE WINDS ARE
EXPECTED TO BE LESS.

NOT TOO MANY CHANGES TO THE FORECAST OTHERWISE...TWEAKED TEMPS DOWN
IN THE MOUNTAIN VALLEYS TONIGHT THOUGH THE RIDGES WILL BE WARM...THE
USUAL WIDE RANGES UNDER DRY/CLEAR CONDITIONS WITH MODERATE WINDS
ALOFT. HIGHS ON SUNDAY WILL BE NEAR THE RECORDS FOR THE DAY AND THE
MONTH...THINK WE WILL BE A COUPLE DEGREES SHY OF THE 97 RECORD IN
DENVER.

.LONG TERM...MODELS HAVE AN UPPER TROUGH PUSHING ACROSS THE FORECAST
AREA SUNDAY NIGHT INTO MONDAY.  STRONG WEST-SOUTHWESTERLY FLOW ALOFT
IS PROGGED AT THE BOTTOM OF THE TROUGH OVER THE FORECAST AREA LATE
SUNDAY NIGHT INTO MONDAY AFTERNOON.  DECREASING ZONAL FLOW ALOFT IS
PROGGED MONDAY NIGHT INTO TUESDAY...WHEN IT BECOMES A BIT
SOUTHWESTERLY LATE IN THE DAY.  THE QG VERTICAL VELOCITY FIELDS HAVE
FAIRLY STRONG UPWARD SYNOPTIC SCALE ENERGY PROGGED SUNDAY NIGHT INTO
MONDAY.  BY MONDAY AFTERNOON STRONG DOWNWARD MOTION IS PROGGED.  BY
TUESDAY...WEAK UPWARD MOTION IS INDICATED.  BOUNDARY LAYER WIND
PROGGS NOW SHOW A COLD FRONT TO MOVE INTO THE FORECAST AREA AROUND
09Z EARLY MONDAY MORNING.  BEHIND THE FRONT...THE FLOW IS NORTH-
NORTHWESTERLY.  BY MONDAY NIGHT...NORMAL DIURNAL WIND PATTERNS ARE
LIKELY.  SOUTH-SOUTHEASTERLIES ARE PROGGED ON TUESDAY.  FOR MOISTURE
...SUNDAY EVENING HAS A BIT IN THE MID LEVELS.  AFTER THAT...THE GFS
HAS THE FORECAST AREA QUITE DRY UNTIL TUESDAY AFTERNOON...WHEN SOME
MID LEVEL MOISTURE MOVES IN.  THE NAM SHOWS MORE MOISTURE IN THE MID
LEVELS THE REST OF THE SUNDAY NIGHT AND MONDAY.  MONDAY NIGHT AND
TUESDAY ARE VERY DRY ON THE NAM.  THE BOUNDARY LAYER DEW POINTS ARE
IN THE 20S F MUCH OF SUNDAY NIGHT.  THEY CLIMB INTO THE 40S F
BRIEFLY MONDAY MORNING BEHIND THE FRONT...THEN THE DRY OUT QUICKLY
INTO THE LOWER 10S F WEST TO THE LOWER 30S F EAST FOR MONDAY
AFTERNOON AND NIGHT.  ON TUESDAY...DEW POINTS ARE IN THE 20S F FOR
MUCH OF THE FORECAST AREA.  PRECIPITABLE WATER PROGGS ARE MAINLY IN
THE 0.15 TO 0.30 INCH RANGE...WITH SOME 0.40S BRIEFLY BEHIND THE
FRONT MONDAY MORNING ONLY.  THERE IS A SMIDGEN OF CAPE IN A FEW
PLACES SUNDAY NIGHT INTO MONDAY EVENING...THEN NONE THROUGH TUESDAY
EVENING.  THE QPF FIELDS HAVE A TINY BIT OF MEASURABLE RAINFALL
SUNDAY NIGHT.  THAT IS ONLY ON THE GFS.  FOR POPS...NONE THROUGH THE
PERIOD.  FOR TEMPERATURES...MONDAY'S HIGHS ARE 9-18 C COLDER THAN
SUNDAY'S.  TUESDAY'S COME UP 3-5 C FROM MONDAY'S.  FOR THE LATER
DAYS...WEDNESDAY THROUGH SATURDAY...MODELS HAVE FAIRLY STRONG
SOUTHWESTERLY FLOW ALOFT FOR THE FORECAST AREA WITH THE UPPER RIDGE
CENTERED OVER THE SOUTHEASTERN UNITED STATES AND AN UPPER TROUGH
NORTHWEST AND NORTH OF COLORADO.   THE UPPER TROUGH NEVER REALLY
PUSHES ACROSS COLORADO...IT STAYS TO THE NORTH.  IT LOOKS PRETTY DRY
AGAIN THROUGH THE PERIOD...WITH THE BEST MOISTURE FOR LATE DAY
WEDNESDAY.  TEMPERATURES STAY A BIT ABOVE SEASONAL NORMALS.

.AVIATION...VFR CONDITIONS EXPECTED THROUGH SUNDAY. WINDS GENERALLY
EXPECTED TO DECRESE THROUGH EARLY EVENING BUT WILL OCCASIONALLY GUST
OUT OF THE NORTHWEST AS HIGH AS 20 KNOTS. DIRECTION WILL TURN TO THE
SOUTHWEST BY LATE EVENING. ON SUNDAY WINDS ARE EXPECTED TO BE
SIMILAR TO TODAY BUT A LITTLE STRONGER...BECOMING NORTHWEST WITH
OCCASIONAL GUSTS IN THE 20 TO 25 KNOT RANGE IN THE AFTERNOON.
