Area forecast discussion, Aug 2, 3:06 PM MDT, 3 hours 27 minutes before

AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE PUEBLO CO
306 PM MDT MON AUG 2 2010

.SHORT TERM...
(TONIGHT AND TUESDAY)

...FLASH FLOOD POTENTIAL AND HEAVY RAIN STILL A THREAT...

CURRENTLY...VERY LITTLE CHANGE IN THE UPPER WEATHER PATTERN THE PAST
FEW DAYS...AND THIS CONTINUES AS THE UPPER RIDGE REMAINS OVER THE
LOWER MISS RIVER VALLEY AND THE TROF SITS OVER THE PAC NW. A VORT
MAX OVER THE 4 CORNERS HAS PROVEN TO BE FOCUS POINT FOR A GREAT
AMOUNT OF CONVECTION OVER THE WESTERN HALF OF COLORADO. SAT WV
IMAGERY INDICATED EARLY THIS MORNING A GOOD AMOUNT OF DRY AIR
ADVECTING INTO THE SE CORNER FROM NM AND THE PANHANDLES...AND THIS
HAS PROVEN TO BE TRUE AS SOUTHERLY SFC FLOW HAS KEPT THE SE PLAINS
DRY AND ALMOST CLOUD-FREE...EAST OF A LINE EXTENDING ROUGHLY FROM
KTAD TO NORTHERN CROWLEY COUNTY.

TEMPS HAVE WARMED TO AROUND 90 F ACROSS THE PLAINS...WITH DEWPOINTS
IN THE MID-50S TO LOWER 60S.

TONIGHT...MODELS CONTINUE TO DROP A FRONTAL BOUNDARY DOWN ACROSS THE
E PLAINS LATER TONIGHT...WITH IT IN THE VICINITY OF A LINE FROM
KIOWA COUNTY BACK TOWARDS I25 AND THE RATON MESA OVERNIGHT. THIS
BOUNDARY IS EXPECTED TO HELP TRIGGER ADDITIONAL SHOWERS AND
THUNDERSTORMS THROUGH THE EVENING...AND LINGER WELL INTO THE NIGHT.
ONGOING GRIDS HAD A GOOD HANDLE ON THE EXPECTED CLOUDY AND WARM
NIGHT AHEAD...AND JUST HAD TO ADJUST POPS GRIDS A BIT AS WELL AS
AVIATION FORECASTS. CURRENT FLASH FLOOD WATCH CONTINUES TIL MIDNIGHT
FOR THE MTS AND HIGHER TERRAIN...AND WILL ALLOW THIS TO RUN SINCE
THESE ARE THE AREAS SO FAR WHERE ACTIVITY IS TAKING PLACE.

TOMORROW...FRONTAL BOUNDARY IS FORECAST TO CONTINUE SOUTH AND DROP
SOUTH OF THE NM/CO BORDER...WITH LLVL EASTERLY UPSLOPE FLOW SETTLING
IN. THE MONSOON PLUME OUT WEST WILL CONTINUE...WITH THE GREATEST
AMOUNT OF AVAILABLE MID AND HIGH LEVEL MOISTURE EXPECTED FOR W CO
AND ALONG THE CONTDVD. HOWEVER...MODELS INDICATE THAT QPF MAXIMUMS
WILL BE OVER THE E PLAINS DUE TO MOIST LLVLS AND UPSLOPE FLOW. THIS
COULD BE TRUE VERY EASILY IF THE NAM MODEL IS CORRECT...SINCE THIS
MODEL PAINTS 0-6 KM BULK SHEARS OF 35-40 KTS AND NEARLY 3K J OF CAPE
POINTING TO A POSSIBLE AFTN/EVE OF SEVERE WX. FORECAST AFTN MAX
TEMPS LOOK VERY SIMILAR TO TODAY...AND ONE DECIDING FACTOR WILL BE
HOW MUCH SOLAR HEATING THE E PLAINS GET BY MID-LATE MORNING.
THEREFORE...CHANCE FOR SEVERE WX FOR THE PLAINS TUE...WHILE A HEAVY
RAIN THREAT CONTINUES ALONG THE CONTDVD AND POSSIBLY EVEN OVER THE
SLV. MODELS DO NOT TOTALY AGREE ON WHAT WILL HAPPEN OVER THE
WEST...SO WILL APPRISE THE INCOMING SHIFT ON FLASH FLOOD POTENTIAL
AND HAVE THEM TAKE ANOTHER LOOK FOR ANY POTENTIAL HIGHLIGHTS. MOORE

.LONG TERM...
(TUESDAY NIGHT THROUGH MONDAY)

...MONSOON CONTINUES THROUGH THURSDAY...THEN DRYS OUT SOME THROUGH
THE WEEKEND...

LOOKS LIKE THE MONSOON WILL REMAIN IN FULL FORCE THROUGH ABOUT
THURSDAY...BEFORE SOME DRIER AIR BEGINS WORKING IN FRIDAY THROUGH
THE WEEKEND.  TUESDAY EVENING...THE JETSTREAM MOVES A LITTLE CLOSER
TO THE AREA...INCREASING STEERING WINDS AND SHEAR VALUES OVER THE
PLAINS...SO THE SEVERE THREAT MAY BE UP A BIT ACROSS THE PLAINS
TUESDAY EVENING.  STILL HEAVY RAIN POSSIBLE BECAUSE ATMOSPHERIC
MOISTURE IS SO GREAT...BUT STORM MOTIONS SHOULD BE A BIT HIGHER SO
PERHAPS THE FLASH FLOOD THREAT WILL BE DOWN ACROSS THE PLAINS.

WEDNESDAY AFTERNOON AND EVENING LOOKS POTENTIAL BUSY...ESPECIALLY
ACROSS THE PLAINS...WITH WHAT LOOKS LIKE A DECENT BOUNDARY MOVING
THROUGH DURING THE AFTERNOON AND EVENING HOURS.  THIS BOUNDARY
SHOULD PROVIDE THE FOCUS FOR ENHANCED CONVECTION...ESPECIALLY ACROSS
THE PLAINS AND ADJACENT MOUNTAINS.  HPC QPF GUIDANCE IS PRETTY
IMPRESSIVE OVER THE EAST...AND BASICALLY USED THIS TO POPULATE THE
FORECAST GRIDS.  THE GFS40 SUPPORTS HPC PRETTY WELL...BUT THE NAM12
IS A LOT LESS BULLISH AND A LOT MORE SCATTERED ON THE COVERAGE.  I
STARTED WITH THE HPC GUIDANCE AND THEN BLENDED AND TAPERED AMOUNTS
DOWN SOME...BUT KEPT THE HPC/GFS THEME GOING.  WILL HAVE TO SEE IF
THIS TYPE OF WIDESPREAD HEAVY PRECIP STILL EXISTS IN LATER RUNS AND
THEN ADJUST ACCORDINGLY.  HARD TO SAY WHETHER OR NOT ANY GIVEN
PRECIP BULLSEYE WILL ACTUALLY MATERIALIZE AT 2 DAYS OUT.

THURSDAY STILL LOOKS LIKE ANOTHER ACTIVE MONSOON DAY...ESPECIALLY
MOUNTAINS AND WEST.  BUT THEN...FROM FRIDAY ONWARD...IT LOOKS LIKE
THE MONSOON PLUME THINS OUT CONSIDERABLY...LEAVING THE BEST ODDS FOR
STORMS OVER THE MOUNTAINS AND WEST...WITH VERY SPOTTY AND NOT REAL
INTENSE ACTIVITY OVER THE EAST.  THIS IS STILL SEVERAL DAYS OUT AND
SUBJECT TO CHANGE SO STAY PLEASE TUNED. LW

&&

.AVIATION...
HEAVY RAIN FROM LINGERING SHOWERS AND THUNDERSTORMS CONTINUES TO BE
A THREAT FOR ALL OF SOUTHERN CO TONIGHT THROUGH 09Z...PRODUCING MVFR
TO IFR CIGS/VIS FOR THE THREE MAIN TAF SITES OF KCOS...KPUB AND
KALS. FRONT WILL DROP SOUTH ACROSS THE E PLAINS TONIGHT...WITH
NORTHERLY WINDS FORECAST FOR KCOS BY OOZ AND AT KPUB BY 02Z.
TOMORROW...HEAVY RAIN PRODUCING REDUCED VISIBILITIES WILL AGAIN BE A
THREAT OVER THE HIGHER TERRAIN AND KALS BEGINNING BY 16Z...WHILE
KCOS AND KPUB WITH HAVE THE ADDED THREAT OF HAIL AFTER 19Z.
