AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
230 PM CDT FRI JUN 20 2003

ANOTHER CROP OF TSTMS LIGHTING UP OVER ERN NM IN ASSOCIATION WITH
THE NEXT SHORTWAVE TROF. SPC ALREADY HAS A SVR TSTM WATCH OUT FOR
THAT PART OF THE STATE. EXPECT THESE THUNDERSTORMS TO CONTINUE MOVG
NNEWD INTO THE PNHDLS LATE THIS AFTN AND TNGT. WILL REVERT TO AREAL
QUALIFIERS FOR TNGT AND RAISE POPS A BIT WITH A TREND TOWARDS
HIGHEST VALUES OVER WRN ZNS. WILL ALSO RETAIN MENTION OF SVR.

FOR SAT...SOME SORT OF SFC TROF OR PSEUDO DRYLINE TO SLIDE EWD AND
MAKE IT ABOUT HALF OR TWO THIRDS OF THE WAY THRU FCST AREA. ENUF
CONVERGENCE ALONG THIS FEATURE WARRANTS LOW POP VALUES ERN ZNS SAT
AFTN AND EVENING. HOWEVER...A LAYER OF WARM AIR ALOFT SHOULD
OVERSPREAD THE REGION THANKS TO MORE W AND SW FLOW...WHICH WILL MAKE
IT TOUGHER FOR STORMS TO FORM.

FROM SUN THRU MIDDLE OF NEXT WEEK A BROAD WESTERN US TROF WILL
DOMINATE WITH A FLAT RIDGE S OF FCST AREA. THIS WILL RESULT IN
TEMPS COMPARABLE TO EARLY SUMMER ALONG WITH LITTLE PROSPECTS FOR
PRECIP. SHORT AND MEDIUM RANGE MODELS IN GOOD AGREEMENT WITH THIS
SCENARIO AND ARE ACCEPTED. AFTER WED THOUGH THE MEDIUM RANGE MODELS
DIVERGE ON EXTENT OF WRN TROF. IT DOES APPEAR A WEAK SFC TROF OR COLD
FRONT MAY SLIDE SEWD INTO THE AREA AROUND THU WITH A MINOR SETBACK IN
TEMPS FORESEEN. IN ADDITION...THIS FRONT OR BOUNDARY MAY SERVE AS A
FOCUSING MECHANISM FOR TSTMS...AND HAVE LEFT LOW POPS IN FOR THU...
THEN EXTENDED THEM INTO THU NIGHT AND FRI. OVERALL...PREVIOUS PCKG IN
DECENT SHAPE AND HAVE RETAINED ITS INTEGRITY. PRELIM VALUES FOLLOW.
