AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
257 PM MDT MON JUN 11 2007

.SHORT TERM...
(TONIGHT AND MONDAY)

...SHORT TERM CONCERNS INCLUDE QPF AND AREAL/TEMPORAL EXTENT OF
   TSRA THROUGH THIS FCST PD...

CURRENTLY...AS PER SAT PIX AND REGIONAL RADARS...MSTR IS INCREASING
OVER THE PLAINS. AS OF 2 PM...ISOLD TSRA ARE ALREADY OCCURRING OVER
THE PLAINS. TSRA ON FAR E PLAINS IS BEING FORCED BY RETROGRADING
DRYLINE AS SEEN IN KPUX BASR R LOOP. ABUNDANT SHOWERS/TSRA ARE NOTED
OVER NM AND ARE MOVG NNE TOWARDS S CO. SOME OF THESE TSRA HAVE
ALREADY CROSSED OVER THE STATE LINE AND OCCURRING OVER THE
SANGRES/WET MTS. ALL OF THIS PRECIP IS BEING FORCED BY A TROUGH OVER
THE SW CONUS...CURRENTLY LOCATED OVER S AZ/N OLD MEX.

TONIGHT...BOTH PRIMARY MODELS INDICATING BAJA TROUGH WILL AFFECT
REGION TONIGHT AND TOMORROW. MAIN DIFF IN GUIDANCE IS TIMING. GFS IS
A BIT QUICKER (OPEN TROUGH) WHILE NAM IS A BIT SLOWER (CLOSED LOW).
IN EITHER CASE WE WILL SEE INCREASING MSTR TONIGHT OVER THE
REGION...ESPECIALLY OVER THE SW AND S MTNS. FOR THIS REASON...I
KEPT POPS UP TONIGHT OVER THESE REGIONS. I ALSO KEPT POPS UP THIS
EVENING OVER THE PLAINS...BUT CUT BACK A BIT DURING THE EARLY
MORNING HOURS AS I REALLY DO NOT SEE THE FORCING NECESSARY FOR
SCTD POPS (CUT DOWN TO ISOLD). WE WILL SEE LOTS OF CLOUDS FA-WIDE
SO TEMPS SHOULD KEEP UP TONIGHT. AS FOR SVR TSRA...WE MAY SEE A
PULSE SVR STORM OR TWO THIS EVENING...BUT WITH 500 MB WINDS VERY
WEAK...SHEAR IS SIMPLY NOT IN PLACE. IT SHOULD BE NOTED
HOWEVER...THAT THE DRYLINE IS MOVG W OVER THE E PLAINS...AND THIS
MAY ASSIST IN SVR POTENTIAL...ESPECIALLY THIS AFTERNOON.

TOMORROW...LOTS OF CLOUDS SHOULD BE OVER THE REGION AS COMPARED TO
CLIMO AS UPPER LOW MOVES OVER AREA. PRECIP SHOULD START A BIT
EARLIER THAN NORMAL AND HAVE POPS INCREASING LATE IN THE MORNING
INTO THE AFTERNOON. OLD ETA MOS LITERALLY GOES BALLISTIC WITH
POPS...ESPECIALLY OVER THE PIKES PEAK REGION LATE IN THE DAY WITH
NEAR 100% POPS AND VERY HI QPF (5). FOR NOW...I THINK THIS IS A BIT
OVERDONE BUT IT COULD THEORETICALLY HAPPEN GIVEN THE SETUP. FOR
NOW...I HAVE 50 POPS OVER THIS REGION LATE IN THE AFTERNOON...BUT
THIS AREA WILL HAVE TO BE WATCHED. AS FOR SVR TOMORROW...SHEAR WILL
BE IN PLACE...BUT I DONT THINK WE WILL HAVE THAT MUCH IN THE WAY OF
CAPE TO PLAY WITH...SO SVR THREAT NOT THAT HI ATTM. HOWEVER...IF WE
DO WARM UP WE COULD HAVE A FEW ROTATING STORMS OVER THE CWA BY LATE
AFTERNOON. THIS WILL BE ESPECIALLY TRUE IF THE NAM (THE SLOWER
MODEL) VERIFIES. /HODANISH

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

...MOSTLY QUIET WEATHER AFTER WEDNESDAY...

.TUESDAY NIGHT AND WEDNESDAY...THE NAM APPEARS TO BE THE OUTLIER
AMONG THE MODELS WITH THE SLOWER EASTWARD PROGRESSION OF THE
TROUGH. THE GFS WAS FOLLOWED FOR THE FORECAST...BUT LATEST
GUIDANCE FROM HPC SUGGESTS THIS SOLUTION MAY BE TOO SLOW. BEST
CHANCES FOR PRECIPITATION WILL BE TUESDAY EVENING. AS THE TROUGH
LINGERS OVER WESTERN KANSAS ON WEDNESDAY...REGION WILL MOSTLY BE
ON THE DRIER WESTERN SIDE OF THE SYSTEM. SCATTERED POPS WERE
MAINTAINED ON THE EASTERN PLAINS SINCE THEY WILL BE CLOSER TO THE
UPPER LOW. OTHERWISE...ONLY SOME ISOLATED POPS WERE LEFT IN THE
FORECAST FOR DURING THE DAY ON WEDNESDAY. WITH THE PROXIMITY OF
THE UPPER LOW AND STRONG JUNE SUNSHINE...IT WOULD NOT TAKE MUCH
MOISTURE TO GET A FEW STORMS GOING...ESPECIALLY OVER THE
MOUNTAINS.

.THURSDAY AND FRIDAY...UPPER LOW SLOWLY DRIFTS FROM WESTERN KANSAS INTO
EASTERN TEXAS. REGION WILL MOSTLY BE UNDER SUBSIDENCE FROM THE
UPPER LOW WITH SOME DRIER MID LEVEL AIR BEING ADVECTING INTO THE
REGION FROM THE NORTH. GRIDS HAVE SOME VERY LOW POPS ON THE PLAINS
WHICH MATCHES OTHER OFFICES. ANY DISTURBANCES ROTATING AROUND THE
BACK SIDE OF THE UPPER LOW MAY ALLOW FOR ENOUGH INSTABILITY TO GET
A THUNDERSTORM OR TWO TO DEVELOP. ANY CONVECTION WOULD BE WEAK
WITH MOSTLY LIKELY HAZARD GUSTY WINDS.

.SATURDAY...NEXT FAIRLY STRONG TROUGH MOVES ON THE PACIFIC
NORTHWEST. SOUTHWEST FLOW DEVELOPS AHEAD OF THE SYSTEM WITH WARM
TEMPERATURES ALOFT. GFS KEEPS A POCKET OF MID LEVEL MOISTURE OVER
THE REGION. IF THE FLOW BECOMES A LITTLE STRONGER FROM THE
SOUTHWEST...THEN SOME DRIER AIR MAY BE ADVECTED INTO THE REGION.
THIS MAY BE THE WARMEST DAY OF THE PERIOD ESPECIALLY ALONG THE
INTERSTATE 25 CORRIDOR. THIS FAR OUT...CANNOT ELIMINATE ALL
CONVECTION FROM THE FORECAST WITH THE POTENTIAL FOR SOME MID LEVEL
MOISTURE...BUT MAIN THREATS FROM ANY STORM WILL LIKELY BE GUSTY
WINDS.

.SUNDAY AND MONDAY...UPPER TROUGH OVER THE PACIFIC NORTHWEST WILL
TRY TO MOVE EASTWARD. THERE IS A VARIETY OF SOLUTIONS BETWEEN THE
MODELS. THE OPERATIONAL GFS IS INDICATING A SUBSTANTIAL UPSLOPE
SURGE ON MONDAY...WHILE ENSEMBLE MEAN TENDS TO KEEP THE TROUGH
FURTHER WEST. LATEST EC LOOKS MORE LIKE THE GFS. GRIDS HAVE SOME
POPS ON THE THE PLAINS AS WELL AS MOUNTAINS TO ACCOUNT FOR THE
POTENTIAL FOR SOME UPSLOPE. TEMPERATURES ARE NEAR
CLIMATOLOGY...BUT WILL BE COOLER IF THE COLD SURGE IS A STRONG AS
SUGGESTED BY GFS. --PGW--

&&

.AVIATION...MAIN CONCERN IS TSRA. DO NOT BELIEVE WE WILL HAVE ANY
CONCERNS WITH LOW CIGS OVER AN EXTENDED PERIOD OF TIME WITH THIS
EVENT AS THIS IS A PRIMARY CONVECTIVE EVENT. OF COURSE...MAY SEE LOW
CIGS WITH TSRA...BUT THIS WILL BE BRIEF. MAIN THREAT OF TSRA WILL BE
LATE AFTERNOON/EARLY EVENING TODAY...AND AGAIN TOMORROW AFTERNOON
LATE.

.PUB WATCHES/WARNINGS/ADVISORIES...
NONE.
