AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
257 PM MDT WED JUL 2 2008

.SHORT TERM...
(TONIGHT AND TOMORROW)

...SHORT TERM CONCERNS INCLUDE TIMING AND EXTENT OF FRONTAL BOUNDARY
ACROSS EASTERN COLORADO ALONG WITH THUNDERSTORM COVERAGE...

CURRENT WATER VAPOR IMAGERY CONTINUES TO SHOW NORTHWEST FLOW MOVING
OVER COLORADO. THE THUNDERSTORM ACTIVITY WILL DECREASE IN THE
WESTERN AREAS AS THE EVENING PROGRESSES. THERE REMAINS THE
POSSIBILITY FOR ISOLATED THUNDERSTORMS ALONG THE EASTERN PLAINS
ENDING BY MID EVENING. FRONTAL PASSAGE SHOULD OCCUR EARLY THIS
EVENING. THE MODELS BOTH SEEM TO BE IN RELATIVE AGREEMENT ON THE
APPROXIMATE TIMING. WITH AN INFLUX OF MID LEVEL MOISTURE...A STRATUS
LAYER WILL FORM OVER SOUTH EASTERN COLORADO. THIS LAYER WILL REMAIN
OVER MOST OF THE AREA UNTIL AFTER DAYBREAK. THIS CLOUD LAYER COUPLED
WITH THE COLD FRONT...WILL CAUSE REDUCED MAXIMUM TEMPERATURES
TOMORROW. THE REDUCED MAXIMUM TEMPERATURES AND THE PRESENCE OF CAP
IN THE SOUNDINGS WILL REDUCE THE THUNDERSTORM THREAT FOR TOMORROW.
THE STRATUS LAYER SHOULD DISSIPATE BY 18Z. THE BEST AREAS FOR
THUNDERSTORM ACTIVITY TOMORROW AFTERNOON SHOULD BE ALONG THE FRONTAL
BOUNDARY IN NORTHERN KIOWA AND OVER THE MOUNTAINS ESPECIALLY THE
SOUTHEAST RANGES. -JC

.LONG TERM...
(THURSDAY NIGHT THROUGH WEDNESDAY)

LINGERING SEVERE THUNDERSTORM THREAT THE CONCERN FOR THURS EVENING.
MAIN FOCUS FOR THUNDERSTORMS WILL BE ALONG THE FRONT TO THE SOUTH...
ACROSS THE TX/OK PANHANDLE INTO NE NM AND ALONG THE EASTERN SLOPES
OF THE SOUTHEAST MOUNTAINS.  WITH 50-55+ DEW POINTS POOLING ALONG
THE EASTERN SLOPES OF THE SE MTS IN EASTERLY UPSLOPE FLOW NAM IS
SHOWING UP TO 2000 J/KG OF CAPE IN THIS REGION.  WITH EASTERLY LOW
LVL FLOW BENEATH NW FLOW ALOFT...DEEP LAYER SHEARS RANGE FROM AROUND
25-30 KTS...ENOUGH TO SUPPORT ISOLATED SEVERE THUNDERSTORMS IN THIS
REGION...WITH MAIN THREATS LARGE HAIL AND DAMAGING WINDS. HOW FAR
EAST TO SPREAD SCT POPS IS THE MAIN QUESTION.  LATEST NAM12 MODEL
SOUNDINGS IN 12Z RUN LOOK CAPPED ACROSS THE PLAINS...AND FORCING
ALOFT APPEARS PRETTY WEAK FROM PV LOBE WHICH ORIGINATES FROM NV
TODAY. BUT IF CONVECTION CAN BE FORCED BY OUTFLOW BOUNDARIES OR IF
SUFFICIENT HEATING IS REALIZED AND CONVECTIVE TEMPS ARE ATTAINED
THEN ITS POSSIBLE SCT POPS MAY BE NEEDED ACROSS THE PLAINS.  CURRENT
POPS ARE IN LINE WITH LATEST GUIDANCE AND PAST PERFORMANCE OF MODELS
SUGGEST NAM IS PROBABLY OVERDOING THE QPF ACROSS SE CO THURS
EVENING. THINK MAIN INSTABILITY AXIS WILL END UP BEING FARTHER SOUTH
ALONG THE FRONT. ANY WEAK FORCING WILL BE EXITING SE CO OVERNIGHT SO
THINK MOST CONVECTION WILL END BY 06Z.

RIDGE AXIS SHIFTS EASTWARD FOR FRIDAY WHICH SPREADS WARMER AIR ALOFT
ACROSS THE REGION BY THE AFTN.  DEW POINTS START OUT IN THE 50S
ACROSS THE LOWER EASTERN SLOPES/SE PLAINS BUT CRASH INTO THE 30S TO
LOWER 40S BY AFTN IN SPITE OF SE LOW LVL FLOW AS DEEP MIXING TAKES
PLACE.  THIS DECREASES THE CAPES TO LESS THAN 800 J/KG AND DEEP
LAYER SHEARS DROP TO LESS THAN 20 KTS.  THUS...THREAT FOR ANY SVR
THUNDERSTORMS APPEARS TO BE NIL.  WARMED UP MAX TEMPS THIS DAY.
DECREASED DEW POINTS ALONG THE I-25 CORRIDOR AS WELL...BUT LATER
SHIFTS MAY NEED TO DROP THEM FURTHER IF LATER RUNS CONTINUE TO SHOW
SUBSTANTIAL DRYING.

SATURDAY/SUN LOOKS RATHER HOT ACROSS THE CWA AS A SERIES OF
SHORTWAVES MOVE THROUGH THE NRN US ROCKIES CUTTING DOWN THE RIDGE TO
THE NORTH...AND DEEPENING THE LEE TROF TO THE EAST.  H7 TEMPS RANGE
FROM +16 TO +20C ACROSS THE AREA...SO LOWER 100S ARE POSSIBLE ACROSS
THE SE PLAINS.  MODEL SOUNDINGS SHOW VERY HIGH BASED MOISTURE MOVING
ACROSS THE AREA ASSOC WITH WEAK SHORTWAVES...SO COULD SEE SOME HIGH
BASED DRY THUNDERSTORMS THESE DAYS.

WEAK COLD FRONT MOVES IN FOR MONDAY THOUGH APPEARS COOLER TEMPS/AND
BEST MOISTURE STAYS OFF TO THE NORTHEAST. COVERAGE OF THUNDERSTORMS WILL
BE DEPENDENT ON HOW QUICKLY THE MOISTURE MOVES IN.  FOR NOW APPEARS
BEST THREAT AREA WILL STAY OF TO THE NORTHEAST UNTIL DEEPER SURGE
MOVES IN LATER MONDAY NIGHT INTO TUES.  UPPER RIDGE REBUILDS OVER
THE WEST BY WED WITH LOW LVL EASTERLY FLOW KEEPING LOW LVL MOISTURE
TRAPPED UNDER THE RIDGE WITH AFTN/EVENING THUNDERSTORMS POSSIBLE
EACH DAY...ESP OVER THE MTS. -KT

&&

.AVIATION...
ISOLATED THUNDERSTORMS THIS AFTERNOON REMAIN A POSSIBLE HAZARD
UNTIL ABOUT MID EVENING.   THE MAIN THREATS WILL BE LOCALLY HEAVY
RAIN OVER THE MTS AND HIGH VALLEYS ALONG WITH SMALL HAIL...WHILE
OVER THE SOUTHEAST PLAINS THE MAIN THREAT WILL BE WIND GUSTS UP TO
50 MPH. THE INCOMING AND SUBSEQUENT LOWERING OF A MID DECK WILL
CAUSE MVFR CONDITIONS TOMORROW MORNING ALONG THE I 25 CORRIDOR.
THERE IS ALSO THE POSSIBILITY FOR THIS LAYER TO THICKEN/LOWER AND
CAUSE IFR CONDITIONS. THIS LAYER WILL CLEAR OUT BY 18Z TOMORROW
AND THE ONLY THREAT WILL BE ISOLATED THUNDERSTORMS ALONG THE
FRONTAL BOUNDARY AND OVER THE MOUNTAINS.

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

.DAY ONE...TODAY AND TONIGHT

ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP
ACROSS THE HIGHER TERRAIN AND THE ADJACENT VALLEYS AND PLAINS
THIS AFTERNOON AND EVENING. A FEW STORMS MAY BE DRY...PRODUCING
CLOUD TO GROUND LIGHTNING AND GUSTY WINDS TO AROUND 50 MPH...WITH
LITTLE OR NO RAINFALL. THIS COULD LEAD TO A FEW FIRE STARTS AND
INCREASED FIRE DANGER...ESPECIALLY ACROSS THE I-25 CORRIDOR. A FEW
OF THE STRONGER STORMS COULD PRODUCE LOCALLY HEAVY RAIN AND HAIL TO
THE SIZE OF PENNIES...ESPECIALLY ACROSS THE FAR EASTERN PLAINS THIS
EVENING...WHERE LOW LEVEL MOISTURE WILL BE INCREASING BEHIND A
PASSING COLD FRONT.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

ON THURSDAY...SEVERE THUNDERSTORMS ARE POSSIBLE OVER THE EASTERN
PLAINS AND EASTERN MOUNTAINS DURING THE AFTERNOON AND EVENING. THE
MAIN THREATS FROM THESE STORMS WILL BE ONE INCH DIAMETER HAIL...OR
LARGER...AND WIND GUSTS IN EXCESS OF 60 MPH.

STARTING ON FRIDAY...WARMER AND DRIER AIR WILL MOVE INTO THE
REGION. AFTERNOON AND EVENING THUNDERSTORMS WILL BE POSSIBLE EACH DAY...AND
THE THREAT FOR MOSTLY DRY THUNDERSTORMS WILL INCREASE THROUGHOUT
THE WEEKEND AND INTO NEXT WEEK.

.SPOTTER INFORMATION STATEMENT...

WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL
BE POSSIBLE ACROSS THE HIGHER TERRAIN AND ADJACENT PLAINS THIS
AFTERNOON AND EVENING.
