AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
315 PM MDT FRI JUL 10 2009

.SHORT TERM...A STRONGLY CAPPED AND VERY MOIST BOUNDARY LAYER
BLANKETING THE PLAINS NOW BEGINNING TO ERODE ALONG THE EDGES/UP
AGAINST THE FOOTHILLS AND PALMER DIVIDE. NEED UPR 80S/LOWER 90S
FARTHER OUT ON THE PLAINS TO BREAK THE INVERSION LAYER UP NEAR
750MB. WHEREAS CLOSER TO THE FOOTHILLS...CONVECTIVE TEMPS ALMOST
REACHED. ONLY A MATTER OF TIME BEFORE WE SEE CONVECTIVE INITIATION
OVER THE FOOTHILLS AND PALMER DIVIDE...HOWEVER HAVE NOTICED A DROP
IN DEWPTS IN THESE AREAS WHICH HAS RAISED THE CONVECTIVE TEMP IN
THESE AREAS.  IN THE PAST 2 HOURS...DEWPT AT DIA FELL 5F...BUT ITS
STILL A RESPECTABLE 58F. BUFKIT SOUNDINGS INDICATE AN IMPRESSIVE
3850J/KG OF CAPE AND NO CIN AT DENVER SHOULD WE REACH A TEMPERATURE
OF 89F. CERTAINLY SOMETHING TO KEEP AN EYE ON.

BELIEVE OTHER REASON FOR THE LACK AND/OR DELAY IN T-STORM DVLPMNT
MAY BE DUE TO THE VERY DRY LOW/MID-LVL AIR WEST OF THE CONT DIVIDE.
MID-AFTERNOON SFC DEWPTS UP THERE ONLY IN THE TEENS/20S WITH A DRY
19F DEWPT ATOP COPPER MTN. FCST SOUNDINGS SHOW SOME MOISTENING AT
MID-LEVELS NEXT SEVERAL HOURS AS THE PLUME OF MOISTURE ROUNDING THE
FRINGE OF THE SRN GREAT PLAINS RIDGE MAKES A GRADUAL SEWRD SHIFT.
THEREFORE SHOULD SEE ISOLATED/SCATTERED STORMS FORMING OVER THE MTN
RIDGES IN THE NEXT FEW HOURS. AND IT IS THESE STORMS THAT COULD
INITIATE STORM ON THE NEARBY PLAINS. HOWEVER...HAVE ALREADY SEEN A
FEW STORMS FIRING OVER SRN LINCOLN COUNTY.

DURING THE NEXT SEVERAL HOURS....COULD SEE T-STORMS OVER AND ALONG
THE FOOTHILLS AND PALMER DIVIDE MOVING OUT ONTO THE PLAINS. BUT
DOUBTFUL ANY WILL BE ABLE TO SUPPORT A WELL DVLPD UPDRAFT ACROSS THE
FAR NERN CORNER EVEN WITH EFFECTIVE BULK SHEAR APPROACHING 30KTS.
THEN AGAIN...SHOULD ONE SUCH UPDRAFT FORM...COULD SEE SOME PRETTY
EXPLOSIVE DEVELOPMENT WITH ALL OF THE POTENTIAL INSTABILITY
AVAILABLE. AFTER MIDNIGHT THE LOSS OF HEATING AND THE LACK OF ANY
SHORTWAVES AROUND...SHOULD SEE THE LAST OF THE CONVECTION BEING
REPLACED BY AREAS OF FOG ON THE PLAINS. WITH THE NAM AND GFS SHOWING
MEAN LAYER PW VALUES INCHING UP OVER 1.5 INCHES OVERNIGHT WITH
E-SELY LOW-LVL FLOW...COULD SEE AREAS OF DENSE FOG ESPECIALLY WITHIN
THE SOUTH PLATTE RIVER VALLEY. COULD SEE SOME OF THIS FOG REACHING
THE METRO AREA SOMETIME AROUND 12Z OR 13Z/SATURDAY.

ON SATURDAY...MODELS STILL SHOW A SUBSTANTIAL AMOUNT OF MOISTURE ON
THE PLAINS. HIGHER ELEVATIONS SHOULD ALSO GET INTO THE ACT. THE DAY
SHOULD START OUT SIMILAR TO TODAY WITH A WIDE AREA OF FOG ON THE
PLAINS AND PCLDY SKIES IN THE HIGH COUNTRY. THEN MODELS SHOW A
RATHER SIGNIFICANT SHORTWAVE RIDING OVER THE TOP OF THE UPPER RIDGE
AND ACROSS NERN COLORADO LATE AFTERNOON OR EARLY EVENING. AT THE
SFC...OLD FRONTAL BNDRY STALLED OUT ACROSS E-CNTRL COLORADO MAY ALSO
ACT AS A FOCUS FOR SCATTERED POSSIBLY STRONG STORM DVLPMNT. WIND
FIELDS SHOW BRISK SELY FLOW ADVECTING HIGH DEWPT AND THETA-E AIR UP
INTO THE FCST AREA THRU THE DAY.  HEAVY RAIN AND LARGE HAIL A
POSSIBILITY. SPC HAS NERN COLORADO UNDER A SLIGHT RISK FOR SEVERE
TOMORROW. NOT UNLIKE TODAY SHOULD SEE INITIAL STORM DVLPMNT OVER AND
NEAR THE FRONT RANGE AND PALMER DVD BEFORE MOVING OUT ONTO THE
PLAINS DURING THE AFTERNOON. LASTLY...LOOKING FOR A 1-2C JUMP IN THE
MAX TEMPERATURE.

.LONG TERM...THE UPPER RIDGE CENTER IS PROGGED TO STAY JUST
SOUTHEAST OF COLORADO SATURDAY NIGHT AND SUNDAY.  SUNDAY NIGHT AND
MONDAY...THE UPPER RIDGE MOVES WESTWARD TO BE SOUTH OF COLORADO.
THE RIDGE FLATTENS SOMEWHAT MONDAY AFTERNOON AND NIGHT AS AN UPPER
TROUGH PUSHES EASTWARD TO THE NORTH OF COLORADO.  THE FLOW ALOFT IS
WEST-SOUTHWESTERLY THROUGH THE PERIODS.  SPEEDS ARE MAINLY IN THE 35
TO 60 KNOT RANGE.  QG VERTICAL VELOCITY FIELDS SHOW WEAK UPWARD
MOTION MOST OF THE PERIODS.  THE BOUNDARY LATER FLOW HAS AN EASTERLY
COMPONENT TO IT MUCH OF THE TIME SATURDAY NIGHT THROUGH SUNDAY
NIGHT.  BY MONDAY...THE LOW LEVEL FLOW HAS A DOWNSLOPING COMPONENT
TO IT.  FOR MOISTURE...THERE IS QUITE A BIT SATURDAY NIGHT INTO
SUNDAY NIGHT...WITH SOME DRYING ON MONDAY.  PRECIPITABLE WATER
VALUES RANGE FROM 0.90 TO 1.20 INCH SATURDAY NIGHT THROUGH SUNDAY
NIGHT.  FOR MONDAY THEY DRY OUT A BIT INTO THE 0.80 TO 1.00 INCH
RANGE.  BOUNDARY LAYER DEW POINT READINGS ARE PROGGED IN THE MID 50S
TO LOWER 60S F SATURDAY NIGHT THROUGH MID DAY MONDAY.  BY MONDAY
AFTERNOON THEY DECREASE INTO THE MID 40S TO MID 50S FOR MUCH OF THE
PLAINS.  STILL IN THE LOWER 60S OVER THE FAR NORTHEAST CORNER.
THERE IS A DECENT THETA-E AXIS OVER THE EASTERN TWO-THIRDS OF THE
FORECAST AREA SATURDAY NIGHT.  THERE IS A THETA-E AXIS OVER ALL THE
FORECAST AREA LATE DAY SUNDAY.  FOR LATE DAY MONDAY...THE THETA-E
AXIS IS OVER THE THE EASTERN BORDER AND PALMER RIDGE.  THERE IS
PRETTY HIGH CAPE PROGGED OVER MOST OF THE PLAINS AND FOOTHILLS
SATURDAY EVENING...WITH LITTLE OVER THE MOUNTAINS.  FOR LATE DAY
SUNDAY...IT LOOKS SIMILAR...WITH MORE OVER THE MOUNTAINS.  FOR LATE
DAY MONDAY...THERE IS DECENT CAPE OVER THE EASTERN HALF OF THE
PLAINS AND PALMER RIDGE...WITH LESS OVER THE REST OF THE PLAINS AND
FOOTHILLS.  THERE IS LITTLE IN THE MOUNTAINS MONDAY.  LAPSE RATE
FIELDS INDICATED PRETTY STEEP RATES SATURDAY EVENING AND LATE DAY
SUNDAY.  THERE IS A BIT OF MID LEVEL CAP OVER THE EASTERN PLAINS
BOTH PERIODS.  BY MONDAY...THE MID LEVEL CAP IS OVER MUCH OF THE
FORECAST AREA.  THE QPF FIELDS HAVE MEASURABLE RAINFALL OVER THE
FORECAST AREA ALL THREE LATE-DAY/EVENING PERIODS...THE MOST ON BOTH
SATURDAY EVENING AND LATE DAY SUNDAY.  SO FOR POPS...20%-30%S LOOK
GOOD FOR SATURDAY EVENING AND LATE DAY SUNDAY.  MONDAYS ARE LOWER.
FOR TEMPERATURES...SUNDAYS HIGHS ARE JUST A TAD ABOVE SATURDAYS.
MONDAYS WARM-UP ABOUT 2-4 C.  FOR THE LATER DAYS...TUESDAY THROUGH
FRIDAY...MODELS HAVE THE UPPER RIDGE JUST SOUTH OF COLORADO AND OVER
COLORADO THROUGH THE PERIOD.  MOISTURE IS NOT GREAT.  TEMPERATURES
LOOK AT OF A BIT ABOVE SEASONAL NORMALS.

&&

.AVIATION...STRONG INVERSION OVER THE AREA COULD BREAK IN THE NEXT
1-3 HOURS. SHOULD THIS OCCUR COULD SEE A COUPLE T-STORMS FORM
AND/OR MOVE ACROSS THE DENVER AREA WITH BRIEF HEAVY RAIN AND SMALL
HAIL A POSSIBILITY UNTIL 02Z THIS EVENING. MAY ALSO SEE CEILINGS
LOWERING TO 6000 FT AGL AND VSBYS AS LOW AS 4 MILES WITH THE HEAVIER
SHOWERS. BETWEEN 12Z AND 16Z/SATURDAY...COULD SEE AREAS OF FOG
FORMING OVER NORTHERN AND EASTERN PORTIONS OF THE DENVER METRO AREA.
THE FOG MAY LOWER VSBYS AT DENVER INTERNATIONAL AIRPORT TO BELOW 3
MILES DURING THIS EARLY MORNING PERIOD. THEN EXPECT TO ANOTHER ROUND
OF MID TO LATE AFTERNOON THUNDERSTORMS IN THE DENVER AREA.

&&

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