AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
352 PM MDT SAT JUL 2 2011

.UPDATE...FORECAST HAS BEEN UPDATED TO INCLUDE SEVERE THUNDERSTORM
WATCH 586 FROM NOAA'S STORM PREDICTION CENTER FOR NORTHEAST
COLORADO. THE WATCH PERIOD RUNS UNTIL 04Z THIS EVENING...UNLESS THE
THREAT FOR SEVERE WEATHER SHOULD END EARLIER THAN THAT. LARGE
HAIL AND DAMAGING THUNDERSTORM WINDS APPEARS TO BE MAIN THREAT.
HOWEVER CAN NOT RULE OUT AN ISOLATED TORNADO IN THE NORTHEAST
CORNER OF THE STATE.

&&

.SHORT TERM...

.PREV DISCUSSION... /ISSUED 310 PM MDT SAT JUL 2 2011/

SHORT TERM...CONVECTIVE TEMPERATURE HAVE FINALLY BEEN REACHED ALONG
THE FRONT RANGE. JUST A MATTER OF TIME BEFORE CONVECTION BEGINS
PRODUCING CG LIGHTNING...GUSTY WINDS...LIGHT-MODERATE RAINFALL AND
POSSIBLY SMALL HAIL. STORMS WITH THIS FIRST WAVE OF CONVECTION
SHOULD CONTINUE TO GROW AS THEY TRACK EAST-SOUTHEAST FED BY 10-15KT
SELY BNDRY LAYER FLOW AND LOW/MID 50 DEG DEWPTS. COULD SEE A COUPLE
OF THESE STORMS GO SEVERE ROUGHLY EAST OF I-25 WITH LARGE HAIL AND
WIND GUSTS TO 60 MPH BEING THE MAIN THREAT. ATTENTION THEN SHIFTS TO
A SECOND WAVE OF STORMS EXPECTED TO DEVELOP OVER AND ALONG THE
NORTHERN FRONT RANGE AFTER 22Z. WEAK SHORTWAVE TROUGH EMBEDDED IN
WLY FLOW ALOFT NOW OVER CNTRL WYOMING/N-CENTRAL IS SLATED TO PASS
OVER NERN COLORADO LATE THIS AFTERNOON AND EARLY THIS EVENING. STORM
PREDICTION CENTER HAS MOST OF NORTHEAST COLORADO UNDER A SLIGHT RISK
OF SVR ATTM. LATEST SFC ANALYZES SHOW THIS AREA STILL WEAKLY
CAPPED...HOWEVER HRRR AND NAM INDICATE A NORTHWEST-TO- SOUTHEAST
SWATH OF 2000-3000J/KG SFC BASED CAPES ACROSS THE NERN CORNER OF THE
STATE FM 02/21Z TO 03/02Z. HELICITIES OVER 250 OUT THERE WITH GUSTY
SELY FLOW. COULD SEE A FEW STORMS OUT THERE PRODUCING HAIL UP TO 2
INCHES IN DIAMETER...GUSTS IN EXCESS OF 60KTS...1 TO 2 INCH RAINFALL
AMOUNTS AND EVEN A FEW TORNADOES. A TORNADO WATCH IS NOW IN EFFECT
FOR ERN WYOMING/WRN NEBRASKA UNTIL 04Z TONIGHT. COULD SEE THIS WATCH
EXPANDED SOUTHWARD INTO NERN COLORADO ANY TIME NOW.

OTHERWISE...SHOULD SEE CONVECTION MOVE EAST AWAY FROM THE FRONT
RANGE THIS EVENING WITH DRYING AND SUBSIDENCE IN THE WAKE OF THE
PASSING SHORTWAVE. MEANWHILE COULD SEE T-STORMS LINGERING WELL AFTER
MIDNIGHT/06Z IN THE FAR ERN ZONES WHERE A MOIST AND UNSTABLE S-SELY
FLOW PERSISTS.

ON SUNDAY...AIRMASS ACROSS THE REGION WILL CONTINUE TO DRY OUT AND
WARM UP WITH THE HIGH PRESSURE ALOFT STRENGTHENING. SEE DAYTIME
TEMPERATURES PUSHING WELL INTO THE 90S AT LOWER ELEVATIONS AND THE
70S AND LOWER 80S IN THE HIGH COUNTRY. COULD STILL SEE STEEP LAPSE
RATES AND POCKETS OF LOW LEVEL MOISTURE PRODUCING ISOLATED LATE DAY
STORMS OVER THE MTNS AND FTHL AREAS ROUGHLY SOUTH OF I-70. THIS
INCLUDES SOUTH PARK. OTHERWISE LOOKING FOR A DRY DAY WITH PLENTY OF
SUNSHINE FOR THE REST OF THE CWFA.

LONG TERM...MODELS KEEP AN UPPER RIDGE CENTER AROUND SOUTHWEST TO
SOUTH CENTRAL COLORADO SUNDAY NIGHT THROUGH TUESDAY NIGHT.  THE FLOW
ALOFT VARIES SOMEWHAT THROUGH THAT PERIOD WITH THE RIDGE AXIS MOVING
ABOUT.  FOR THE MOST PART JET LEVEL WINDS WILL BE WEST-NORTHWESTERLY
FOR THE CWA.  THERE IS A WEAK UPPER TROUGH WAY NORTH AND NORTHEAST
OF COLORADO MOVING EAST FROM LATER MONDAY ONWARD. THIS SEEMS TO HELP
BRING IN A COOLER AIRMASS SOMETIME LATER MONDAY...CONTINUING THROUGH
TUESDAY.  THE QG VERTICAL VELOCITY IS BENIGN TO VERY WEAK UPWARD
MOTION FOR THE CWA SUNDAY NIGHT THROUGH TUESDAY NIGHT.  THE LOW
LEVEL WINDS LOOK TO ADHERE TO NORMAL PATTERNS SUNDAY NIGHT INTO
MONDAY AFTERNOON...THEN A WEAK SURGE MOVES IN.  UPSLOPE FLOW IS
PROGGED MONDAY EVENING THROUGH TUESDAY NIGHT.  FOR MOISTURE...THERE
IS BIT IN THE MID AND UPPER LEVELS SUNDAY EVENING.  OVERNIGHT SUNDAY
AND MONDAY MORNING LOOK PRETTY DRY.  FOR LATE DAY MONDAY AND MONDAY
NIGHT...MOISTURE INCREASES...WITH MORE IN THE MID AND UPPER LEVELS.
ON TUESDAY AND TUESDAY EVENING...MOISTURE IS PRETTY DEEP...WITH SOME
EVEN IN THE LOWER LEVELS.  DEW POINT PROGGS HAVE READINGS IN THE
35-45 F RANGE SUNDAY NIGHT...WITH SOMEWHAT HIGHER VALUES OVER THE
NORTHEAST BORDER.  THEY ARE IN THE 35 F WEST TO 55 F EAST RANGE ON
MONDAY.  BY MONDAY NIGHT AND TUESDAY...THEY CLIMB INTO THE 50S F
WEST TO THE MID 60S F EAST.  PRECIPITABLE WATER PROGGS SHOW THIS
TREND AS WELL...WITH VALUES AROUND 0.60 INCH SUNDAY NIGHT...GETTING
IN TO THE 1.00-1.50 INCH RANGE TUESDAY AND TUESDAY EVENING.  LAPSE
RATES ARE PRETTY STEEP SUNDAY EVENING AND AGAIN LATE DAY MONDAY.
THERE ARE NOT AS GOOD ON TUESDAY.  THERE IS SOME CAPE AROUND SUNDAY
EVENING...ESPECIALLY OVER THE MOUNTAINS AND NORTHEAST CORNER.
THERE CAPE IS ONLY FAIR LATE DAY MONDAY...WITH THE BEST OVER THE
MOUNTAINS AND FOOTHILLS.  THERE IS SOME CAPE OVER ALL THE CWA
TUESDAY...BUT VALUES ARE UNDER 1600 J/KG.   THE QPF FIELDS SHOW NO
MEASURABLE PRECIPITATION FOR THE CWA SUNDAY NIGHT AND MUCH OF
MONDAY.  BY MONDAY AFTERNOON AND NIGHT...BOTH MODELS HAVE A TAD OF
MEASURABLE PRECIPITATION.  BY LATER TUESDAY AND TUESDAY EVENING...
HIGHER AMOUNTS OF MEASURABLE RAINFALL ARE INDICATED ON BOTH MODELS
FOR ALL OF THE CWA...THE SOUTHEAST CORNING LOOKING THE DRIEST.  SO
FOR POPS...WILL GO MINIMAL CHANCES OVER THE HIGH COUNTRY SUNDAY
EVENING.  WILL GO WITH 10-20%S LATE DAY MONDAY.  WILL INCREASE POPS
TO 30-40%S FOR TUESDAY AFTERNOON AND EVENING WITH THE DECENT
MOISTURE IN MIND.  FOR TEMPERATURES...MONDAY'S HIGHS WILL BE CLOSE
TO SUNDAY'S...MAYBE A TAD WARMER.  TUESDAY'S READINGS ARE 4-8C
COOLER THAN MONDAY'S ON THE NAM...BUT ONLY SLIGHTLY COOLER ON THE
GFS.  FOR THE LATER DAYS...WEDNESDAY THROUGH SATURDAY...THE UPPER
RIDGE FLATTENS A TINY BIT WITH ITS CENTER TO MOVE SOUTH INTO NEW
MEXICO...THEN SOUTHEAST BY SATURDAY.  MOISTURE LOOKS PRETTY GOOD ON
BOTH THE GFS AND ECMWF...SO WILL GO WITH 20-30% POPS THROUGH THE
PERIOD.  TEMPERATURES LOOK TO BE AROUND SEASONAL NORMALS TO SLIGHTLY
BELOW.

&&

.AVIATION...SCATTERED THUNDERSTORMS EXPECTED TO MOVE ACROSS THE
DENVER METRO AREA NOW THROUGH 01Z THIS EVENING. STORMS WILL
GENERALLY PRODUCE GUSTY ERRATIC WINDS POTENTIALLY TO 50 MPH...
SEVERAL MINUTES OF LIGHT TO MODERATE RAINFALL...AND POSSIBLY SMALL
HAIL. HOWEVER CAN NOT RULE OUT A SEVERE T-STORM OR TWO CAPABLE OF
ONE INCH DIAMETER HAIL AND WIND GUSTS TO 60 MPH. STORMS ARE EXPECTED
TO MOVE EAST OF THE DENVER METRO AREA AFTER 02Z THIS EVENING
FOLLOWING THE PASSAGE OF A WEAK UPPER AIR DISTURBANCE. VISIBILITIES
COULD BRIEFLY LOWER TO 3-4 MILES WITH THE RAINFALL AND STORM CLOUD
BASES AS LOW AS 6000 FT AGL. CONDITIONS IMPROVE LATER THIS EVENING
AS DRIER AIR MOVES IN FROM THE WEST. ON SUNDAY...ANTICIPATE VFR
CONDITIONS UNDER A STRONG RIDGE OF HIGH PRESSURE AND LIGHT DIURNAL
WINDS.

.HYDROLOGY...WILL CONTINUE TO SEE THE TYPICAL DIURNAL RISE AND FALL
CYCLE ON AREA RIVERS. ALONG THE FRONT RANGE...FLOOD ADVISORIES
REMAIN IN EFFECT FOR THE BIG THOMPSON AT ESTES PARK AND THE CACHE LA
POUDRE RIVER. LEVELS HAVE FALLEN ON BOTH RIVERS TODAY...BUT WILL
LIKELY RISE AGAIN TONIGHT AND REMAIN AT ACTION STAGE OVERNIGHT INTO
TOMORROW. FLOOD ADVISORIES ALSO REMAIN IN EFFECT FOR RIVERS IN GRAND
AND JACKSON COUNTIES ON THE WEST SLOPE. DO NOT SEE PEAKS REACHING
LEVELS AS HIGH AS THEY WERE A COUPLE DAYS AGO. ISOLATED-SCATTERED
THUNDERSTORMS LATE THIS AFTERNOON COULD CAUSE A BRIEF SPIKE ON FRONT
RANGE RIVER FLOWS. HOWEVER THE STRONGER STORMS FARTHER OUT ON THE
PLAINS WILL PRODUCE THE HEAVIER RAINFALL.

HIGH COUNTRY SNOWMELT WILL CONTINUE WITH THE UNSEASONABLY WARM
TEMPERATURES THE NEXT 24 HOURS.

FLOOD ADVISORIES...

CURRENTLY IN EFFECT FOR THE BIG THOMPSON RIVER THROUGH ESTES PARK
UNTIL NOON MONDAY. ADVISORIES ALSO IN EFFECT ON THE CACHE LA
POUDRE RIVER FROM THE CANYON MOUTH TO GREELEY...THE COLORADO RIVER
NEAR KREMMLING...THE SAINT LOUIS CREEK BETWEEN FRASIER AND
TABERNASH IN GRAND COUNTY...AND FRASIER RIVER IN GRAND COUNTY
UNTIL MONDAY AFTERNOON.
