AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
345 PM CDT TUE AUG 10 2004

.DISCUSSION...
ACTIVE WEATHER PATTERN APPEARS TO BE SETTING UP FOR TONIGHT ACROSS
THE REGION AS APPORACHING H7 S/W MOVES TOWARDS THE REGION.  BIG
QUESTION RIGHT NOW IS WHETHER OR NOT STORMS WILL FORM ACROSS THE
REGION PRIOR TO S/W PASSAGE.  DEWPTS ARE NOT AS HIGH AS THIS TIME
YESTERDAY...BUT DEVELOPING SFC LOW OVER SE CO HAS HELPED TO POOL
MOISTURE OVER THE OK PNHDL.  ADDITIONALLY...SFC BOUNDARY RUNS FROM
NEAR TURKEY OVER AMARILLO TO NEAR STRATFORD LATE THIS AFTERNOON AND
THIS COULD INITIATE STORMS.  WILL HAVE TO WATCH CLOSELY...AND FEEL
SVR WX THREAT WILL BE EARLY ON AS STORMS DEVELOP AND MATURE.
TORNADO THREAT IS NOT QUITE AS HIGH AS WINDSPEEDS ARE FAIRLY WEAK
BELOW 600 MB.  DAMAGING WINDS AND LOW END SVR HAIL SHOULD BE THE
BIG ISSUE...THAT IS UNTIL LATE TONIGHT.

STORMS FIRING ACROSS CO AND NM SHOULD EVOLVE INTO A MCS AND ROLL
ACROSS THE REGION OVERNIGHT.  THE BEST CHANCE FOR STORMS SHOULD BE
OVER THE NE TX AND ERN OK PNHDLS...BUT ALL OF THE AREA SHOULD SEE A
GOOD CHANCE AT RAIN.  SEVERE THREAT APPEARS TO EVOLVE INTO A
DAMAGING WIND SCENARIO...ESPECIALLY IF THE STORMS CAN GET ORGANIZED
EARLY IN THEIR LIFE CYCLE.  ONLY CHANGES TO GRIDS/FCST IN THE SHORT
TERM WERE TO ADJUST POP GRIDS TO REFLECT EXPECTED MOVEMENT AND
COVERAGE OF STORMS AND TO TWEAK TEMPS.

COLD FRONT APPEARS TO HOLD OFF UNTIL EARLY TOMORROW MORNING AS 20Z
SFC ANALYSIS SHOWS THIS STILL LOCATED OVER NRN KS/SRN NE.
ADDITIONALLY...STRONG LOW ACROSS THE NRN U.S. STILL DIVING SOUTH AND
THIS WILL HOLD FRONT UP A BIT AS WELL.  THIS LOW WILL HELP TO
ESTABLISH DEEP TROF ACROSS THE ERN U.S...WITH NORTHWEST FLOW
ENTRENCHED OVER THE REGION AT LEAST THROUGH THE NEXT 7 DAYS. PRECIP
CHANCES WILL BE MODERATED BY ANY S/W ACTIVITY PASSING ACROSS THE
AREA AND ALSO BY AMOUNT OF LOW-LEVEL HEATING TO DESTABILIZE THE
ATMOSPHERE.  DID ADD IN 10% POPS FOR LATE SUNDAY INTO MONDAY FOR
POSSIBLE S/W MOVING ACROSS THE REGION.  OTHERWISE...NO CHANGES TO
GRIDS BEYOND THURSDAY.
