AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
347 AM MDT SUN MAY 29 2005

.SHORT TERM...
(TODAY AND TONIGHT)

MAIN CHALLENGE TODAY IS TIMING OF FRONT AND ITS AFFECT ON TEMPS AND
THUNDERSTORM CHANCES/STRENGTH...

AS 09Z...COLD FRONT HAS MOVED INTO NE CO...ALONG A LINE ROUGHLY FROM
CASTLE ROCK...TO KAKO...TO KIML.  FRONT SHOULD BE REACHING KMNH
WITHIN THE NEXT HOUR. LOOKS LIKE RUC40 HAS A BETTER HANDLE
ON TIMING OF THE FRONT VS ETA12 WHICH LOOKS TOO SLOW. BY 15Z
RUC 40 HAS FRONT POSITIONED NEAR THE ARKANSAS RIVER...WHICH SHOULD
PROGRESS SOUTHWARD THROUGH REMAINDER OF FCST AREA BY 18-21Z.
MAIN CHALLENGE TODAY WILL BE HOW DEEP THE COOL AIR IS BEHIND THE
FRONT...AND HOW QUICKLY THE LOWER LEVELS WILL STABILIZE BEHIND THE
FRONT...WHICH WOULD LIMIT AFTN THUNDERSTORM COVERAGE.  ETA12 TAKEN
FOR FACE VALUE KEEPS SFC DEW POINTS IN THE 50S BEHIND THE FRONT
ACROSS MUCH OF SOUTHEAST COLORADO...WITH A RIBBON OF AROUND
1000 J/KG CAPE ACROSS ALONG THE CO/NM BORDER. PRETTY GOOD CAP
ACROSS NRN SECTIONS OF THE EAST PLAINS (EL PASO/KIOWA COUNTIES) IN
MODEL SOUNDINGS.  FOR UPPER SUPPORT...APPEARS TO BE A SERIES OF WEAK
SHORTWAVES EMBEDDED IN THE FLOW ALOFT...ONE ENTERING WRN CO ATTM
KEEPING SOME ISOLATED SHOWERS GOING ACROSS NW PARTS OF THE STATE.
MODELS BRING THIS FEATURE ACROSS CO TODAY.  THAT COMBINED WITH
EASTERLY UPSLOPE FLOW SHOULD HELP THUNDERSTORMS GET GOING ACROSS THE
EASTERN MOUNTAINS.  HOW STRONG THEY STAY AS THEY MOVE OFF INTO THE
SOUTHEAST PLAINS WILL DEPEND ON HOW COOL/STABLE THE SFC AIRMASS
WILL BE.  THINK THE ETA12 ISNT BRINGING ENOUGH COLD AIR IN BEHIND
THE FRONT...WITH THE HIGHER CAPES A BIT OVERDONE.  BEST CHANCE OF
SVR WOULD BE NEAR THE CO/NM BORDER.  WITH EASTERLY FLOW BENEATH
WRLY FLOW ALOFT...DEEP LAYER SHEARS ARE RESPECTABLE (35-40KTS) SO IF
INSTABILITY IS THERE...THEN THERE WILL BE ENOUGH SHEAR FOR
SUPERCELLS.  THIS SCENARIO BEARS WATCHING...BUT FOR NOW THINK THE
BEST THREAT WILL BE ACROSS THE SRN BORDER COUNTIES. AND IF FRONT
ADVANCES TOO FAR SOUTH...MAY NOT SEE ANY SVR.

OVERNIGHT ...NICE WAA OVERRUNNING PATTERN SETS UP FOR WIDESPREAD
PRECIPITATION ACROSS THE SOUTHEAST PLAINS.  WILL BE DEALING WITH LOW
IFR/LIFR CIGS FOR TAF SITES EAST OF THE MTS.  WILL PROBABLY SEE
CONVECTION ALONG/BEHIND THE FRONT CONGEAL INTO AN MCS ACROSS EXTREME
SOUTHEAST CO/NE NM AND THE TX/OK PANHANDLES OVERNIGHT.  HAVE BOOSTED
THE POPS FOR THE SRN TIER INTO THE LIKELY CATEGORY.  OTHER FOCUS
FOR PERSISTENT SHOWERS WILL BE ALONG EAST FACING SLOPES OF SOUTHEAST
MTS IN EASTERLY UPSLOPE FAVORED REGIONS.  AGAIN...BOOSTED POPS FOR
THESE AREAS.

NOT TO BE LEFT OUT...WRN MTS WILL SEE SOME ISOLATED/SCATTERED
DIURNAL TSTORMS WITH SHORTWAVE MOVING ACROSS AREA TODAY.  TEMPS OUT
WEST WILL BE A COUPLE DEGREES COOLER THAN YESTERDAY.  HIGHER
ELEVATION SNOTEL SITES SHOWED A MINOR SLOWING IN THE MELT OFF
YESTERDAY...AND EXPECT THAT TO CONTINUE AGAIN TODAY.  THIS SHOULD
RELIEVE SOME OF THE HIGH FLOWS THAT WEVE BEEN SEEING OF LATE...AND
IN FACT MOST RIVER GAGES HAVE BEEN SHOWING A SLIGHT DECLINE BELOW
ACTION STAGE.  WITH MIN TEMPS AT NIGHT REMAINING AROUND OR ABOVE
FREEZING THROUGH TONIGHT...STILL EXPECT THE MELT TO CONTINUE EVEN
THOUGH IT SLOWS A BIT...SO HIGH FLOWS STILL EXPECTED TO CONTINUE
THROUGH THE HOLIDAY WEEKEND. -KT

.LONG TERM...
(MEMORIAL DAY THROUGH SATURDAY)

...COOL AND UNSETTLED THROUGH PERIOD...MONDAY COULD SEE SOME COOL
   TEMP SVR WX...

THE WEATHER DURING THIS PERIOD...ESPECIALLY THE FIRST 2/3RS...IS
GOING TO BE UNSETTLED. THIS IS GOOD AS WE COULD USE THE PRECIP OVER
THE REGION AS IT HAS BEEN DRY...ESPECIALLY IN THE MTNS AND I-25
CORRIDOR.

MEMORIAL DAY...THIS DAY IS GOING TO HAVE TO BE WATCHED VERY, VERY
CAREFULLY AS IT COULD BE A CLASSIC DAY 2 SETUP. THE FRONT IS COMING
DOWN TODAY AND BY MONDAY WE WILL BE UNDER SE UPSLOPE. THIS UPSLOPE
WILL BE ENHANCED GREATLY BY A RATHER POTENT DISTURBANCE MOVING
TOWARDS THE REGION FROM THE WEST. DEEP SHEAR AND ENHANCED LLVL SHEAR
WILL LIKELY BE QUITE STRONG MONDAY AFTERNOON ACROSS THE PLAINS.
PROBLEM FOR CONVECTIVE INITIATION WILL BE HOW COOL WILL IT BE??. IF
IT IS TOO COOL THEN CONVECTION WILL NOT BE ABLE TO FIRE...BUT IF
CONVECTION GETS GOING AND IT IS SURFACE BASED...THEN WE WILL SEE THE
POSSIBILITY OF TORNADOES ON THIS DATE. THIS DAY REMINDS ME OF THE
ELLICOTT TORNADO DAY OF A FEW YEARS BACK...IT WAS QUITE COOL ON THAT
DATE (60S) BUT UPPER TEMPS WERE ALSO QUITE COOL. CAPE WAS NOT THAT
IMPRESSIVE (1500 J/KG) BUT SHEAR WAS STRONG. T/TDS WERE LOW AND A SUP
DEVELOPED ON A BOUNDARY ACROSS EL PASO...AND WE ALL KNOW WHAT
HAPPENED AFTER THAT. ALSO ON THIS DATE NO SVR WENT UP OVER THE
REMAINDER OF THE PLAINS (TOO STABLE)...IT ONLY FIRED ON THE PALMER
AND RATON. TORNADIC SUPS WENT UP ON BOTH DIVIDES. CURENT DAY 2 HAS
THE AREA OUTLOOKED. OF COURSE...IT ITS TOO COOL MONDAY FOR
CONVECTION TO INITIATE...THEN WE MAY JUST SEE SOME BENEFICIAL
STRATIFORM RAIN ACROSS THE REGION.

LATE MONDAY INTO EARLY TUESDAY...DISTURBANCE MOVES THROUGH. SHOULD
BRING A GOOD CHANCE OF PRECIP TO THE PLAINS DURING THIS TIME PERIOD
AND HAVE MATCHED UP WITH GLD AND BOU POPS TO REFLECT THIS.

AFTER THIS SYSTEM MOVES THROUGH...BROAD FLAT TROUGH IS FCST TO SET
UP OVER THE W CONUS...WITH THE MAIN FLOW ALONG OR S OF CO. THIS
SHOULD KEEP THE AREA ON THE COOL SIDE OF THINGS. THIS PATTERN WILL
TEND TO ALLOW A BIT MORE UPSLOPE INTO THE REGION AND BELIEVE WE
WILL SEE A PRETTY GOOD CHANCE OF AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS INTO MID WEEK. BY LATE WEEK AREA IS UNDER SW FLOW
ALOFT WHICH SHOULD WARM THINGS UP...HOWEVER IF THE JET IS A BIT
FARTHER SOUTH THEN WE COULD ONCE AGAIN BE IN COOLER UPSLOPE.

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

RIVERS AND CREEKS WILL CONTINUE TO RUN HIGH ACROSS SOUTH CENTRAL AND
SOUTHEAST COLORADO THROUGH TONIGHT...ESPECIALLY ACROSS THE UPPER RIO

REGION AND RATON MESA AREAS TOMORROW. THERE IS A POSSIBILITY THE
ATMOSPHERE MAY BE TOO STABLE FOR THUNDERSTORMS TO DEVELOP TOMORROW...
BUT IF THEY DO DEVELOP...CONDITIONS WILL BE FAVORABLE FOR THEM TO
BECOME SEVERE. ALONG WITH LARGE HAIL AND STRONG WINDS...A TORNADO OR
TWO WILL BE POSSIBLE...AS LOW LEVEL WIND SHEAR WILL BE QUITE
FAVORABLE FOR STORM ROTATION.

DURING THE REST OF THE WEEK THE WEATHER IS EXPECTED TO BE
UNSETTLED...AND THUNDERSTORMS ARE EXPECTED EACH DAY DURING THE
