Severe Thunderstorm Warning 128, NWS Pueblo, CO

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
227 PM MDT FRI JUL 9 2004

.SHORT TERM...
(TONIGHT AND SATURDAY)

WEATHER ISSUE IS HOW WIDESPREAD AND STRONG WILL THE NEXT FEW ROUNDS
OF THUNDERSTORMS BE?  CURRENTLY...CWFA NOTING MOSTLY CLEAR TO
PARTLY CLOUDY SKIES ALONG WITH A FEW CELLS BEGINNING TO DEVELOP OVER
WESTERN LAS ANIMAS AND WESTERN EL PASO COUNTIES.

LATEST GOES SOUNDED CAPES RANGE FROM NEAR 0 J/KG PORTIONS OF THE
WESTERN CWFA TO AROUND 5000 J/KG FAR EASTERN SECTIONS...WHILE LIS
VARY FROM AROUND 0C WESTERN SECTIONS TO -8C EASTERN SECTIONS.
CONVECTIVE INHIBITION STILL HOLDING MAJORITY OF CONVECTION AT BAY
WITH VALUES OF 85 TO 180 STILL NOTED EASTERN SECTIONS EARLY THIS
AFTERNOON.

A BROAD AREA OF UPPER LEVEL HIGH PRESSURE IS PROJECTED TO CONTINUE
FROM NORTHERN OLD MEXICO INTO EASTERN COLORADO WITH ENOUGH
ATMOSPHERIC MOISTURE AS WELL AS DAILY HEATING IN THE AREA TO PRODUCE
ISOLATED TO SCATTERED MAINLY AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORM DURING THE SHORT TERM.

AT THE SURFACE...A MOIST UPSLOPE FLOW REMAINS IN PLACE INTO THE EARLY
EVENING HOURS OVER THE EASTERN PLAINS WITH RELATIVELY WEAK LEE-SIDE
TROUGH SETTING UP JUST EAST OF THE I-25 CORRIDOR LATER IN THE
EVENING. WILL INCREASE POPS PORTIONS OF THE EASTERN PLAINS TONIGHT
AND WOULD NOT BE TOO SURPRISED TO SEE A FEW OF THESE STORMS ENTER THE
SEVERE CATEGORY AS CURRENTLY MENTIONED IN THE HWO PRODUCT.
MAXIMUM AND MINIMUM TEMPERATURES SHOULD BE SIMILAR OVER MAJORITY OF
CWFA TO VALUES NOTED DURING THE PREVIOUS 24 HOURS.

THANKS SURROUNDING OFFICES FOR COORDINATION.

.LONG TERM...
(SUNDAY THROUGH FRIDAY)

...RELATIVELY HOT WEATHER STILL IN THE OFFING FOR NEXT WEEK...
...LITTLE CHANCE FOR WIDESPREAD WETTING RAINFALL NEXT WEEK...

SAT NGT AND SUN...ELONGATED UPPER LEVEL HIGH PRESSURE AREA WILL
EXTEND FROM THE CNTRL PLAINS INTO PARTS OF THE DESERT SW WITH SW-
WLY FLOW PROJECTED FOR THE CNTRL ROCKIES.  WK TROPICAL-ORIGIN MID
LEVEL SHORTWAVE TROUGHS (AND SOME MOISTURE) CONTINUE TO BE PROGGED
TO MOVE ACROSS THE CNTRL ROCKIES SAT NGT AND THEN INTO THE CNTRL
PLAINS FOR SUN.  GIVEN THE DAYTIME HEATING AND DESTABILIZING
ATMOSPHERE ALONG WITH SOME SYNOPTIC SUPPORT...THERE SHOULD BE ISOLD-
SCT HIGH BASED SHRA/TSRA POTENTIAL ACROSS THE CWA SAT EVE.  MOST
OF THE ACTIVITY DISSIPATE SHORTLY 10PM OR 12AM...AS THE CONVECTIVE
PRECIPITATION EVOLVES INTO A NOCTURNAL MCS ACROSS THE CNTRL PLAINS.
LOOKS LIKE A REPEAT PERFORMANCE ON SUN...HOWEVER...A SLIGHT DRIER
AIR MASS ALOFT MOVES INTO THE CNTRL ROCKIES FROM THE W-NW...WHICH
COULD CUT DOWN ON THE COVERAGE SUN AFTN/EVE.  AT OR ABOVE AVE JUL
TEMPS SHOULD BE IN THE OFFING WITH 90S BELOW 6K FT MSL AND
50S/60S/70S/80S IN THE MTS AND HIGH VALLEYS ON SUN.

MON THROUGH FRI...PROJECTION OF A LARGE UPPER LEVEL HIGH PRESSURE
SYSTEM OVER THE 4 CORNERS REGIONS STILL APPEARS TO BE ON TRACK WITH
SOME SUBTLE DIFFERENCES OF THE RIDGE AXIS LOCATION.  FOR MON-THU...IT
APPEARS THIS BROAD AREA OF HIGH PRESSURE WILL BE DIRECTLY OVER CO.
GFS LOOKS TO BE SUFFERING FROM ITS CONVECTIVE PRECIPITATION
BOMBS...WHICH ULTIMATELY AFFECTS THE SUB-SCALE/SFC LEVELS. WILL
CONTINUE TO FORECAST TEMPS IN THE 90S BELOW 6K FT MSL...WHICH ISNT
TOO FAR AWAY FROM THE MEX GUIDANCE.  PLACEMENT OF THE MID/UPPER LEVEL
RIDGE AXIS WILL BE IMPORTANT IN TERMS OF THE AVAILABLE MOISTURE TO
GENERATE CONVECTIVE PRECIPITATION.  GFS NOW SHOWING SIGNS OF
MONSOONAL MOISTURE(LOW/MID LEVEL) OLD MEXICO MOISTURE CONTINUING TO
MIGRATE OUT OF OLD MEXICO AND INTO AZ WITH A DEEP S-SWLY FLOW ON
THE W SIDE OF THE MID/UPPER HIGH PRESSURE AREA.  ALSO...THERE ARE
HINTS OF TROPICAL MID LEVEL SHORTWAVE TROUGHS(ELY WAVES) ROTATING
AROUND THE LARGE HIGH WITH THE GFS TRYING TO MOVE SOME OF THEM
DIRECTLY THROUGH THE UPPER HIGH.  ANOTHER ISSUE TO KEEP IN MIND IS IF
THE UPPER LEVEL RIDGE AXIS IS A LITTLE FURTHER W(MUCH LIKE THE ECMWF
SUPPORTS FOR FRI(DAY 7))...THEN ERN CO WILL BE UNDER THE POTENTIAL
FOR SHALLOW COLD FRONT/MCS OUTFLOW BOUNDARIES INTRUSIONS EACH DAY...
WHICH COULD MOISTEN UP THE LOW LEVELS AND INCREASE INSTABILITY
RESULTING IN MORE THUNDERSTORM POTENTIAL.  OR...THE UPPER HIGH COULD
BE DIRECTLY OVERHEAD AND ITS JUST HOT WITH MAINLY ISOLD AFTN/EVE
SHRA/TSRA ACROSS THE HIGH COUNTRY AND DRIFTING IN ANY DIRECTION. ONLY
MADE A FEW MODIFICATIONS TO MON THROUGH FRI...SO RELATIVELY HOT AND
LOW POP/WX CHANCES WILL BE THE RULE. METZE

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH CENTRAL AND SOUTHEAST
COLORADO.

.DAY ONE...TODAY AND TONIGHT.

ONE OR TWO SEVERE THUNDERSTORMS WILL BE POSSIBLE THIS AFTERNOON AND
EVENING OVER THE SOUTHEAST COLORADO PLAINS. THE PRIMARY THREAT FROM
THESE STORMS WILL BE WIND GUSTS TO 65 MPH AND HAIL UP TO THE SIZE
OF QUARTERS. THE GREATEST CHANCE FOR SEVERE THUNDERSTORM ACTIVITY
WILL GENERALLY BE NORTH AND EAST OF A LINE FROM PIKES PEAK...TO
PUEBLO...TO KIM.

MOIST UPSLOPE FLOW ASSOCIATED WITH A LARGE AREA OF THUNDERSTORMS OVER
KANSAS LAST NIGHT HAS DEVELOPED OVER THE REGION. THE COMBINATION OF
THE INSTABILITY AND UPSLOPE FLOW WILL ALLOW ONE OR TWO SEVERE STORMS
TO DEVELOP OVER THE PLAINS THIS AFTERNOON AND EARLY EVENING. IN
ADDITION...LOCALLY HEAVY RAINS WILL BE POSSIBLE OVER THE PLAINS.

OVER THE MOUNTAINS...MOISTURE FROM MEXICO WAS MOVING NORTHEAST THIS
MORNING. THIS WILL ALLOW FOR SCATTERED THUNDERSTORMS TO DEVELOP
OVER THE INTERIOR COLORADO MOUNTAINS THIS AFTERNOON AND EARLY
EVENING. THE PRIMARY THREAT FROM THESE STORMS WILL BE CLOUD TO
GROUND LIGHTNING.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH NEXT THURSDAY.

ISOLATED MAINLY AFTERNOON AND EVENING THUNDERSTORMS WILL BE POSSIBLE
EACH DAY ACROSS PORTIONS OF SOUTHEAST AND SOUTH CENTRAL COLORADO.
THESE THUNDERSTORMS ARE EXPECTED TO BE PRIMARILY DRY...SO THE MAIN
THREAT WILL BE CLOUD TO GROUND LIGHTNING AND GUSTY WINDS.

.SPOTTER INFORMATION STATEMENT...

WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS
WILL BE POSSIBLE ACROSS THE PIKES PEAK REGION AND ALONG THE I-25
CORRIDOR THIS AFTERNOON AND THIS EVENING.
