AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE FORT WORTH TX
605 PM CDT TUE JUN 3 2003

PUBLIC UPDATE...
HAVE UDPATED FOR WATCH...AND TO INCLUDE THREAT OF SEVERE.    42

605 PM AVIATION DISCUSSION...
MOST OF THE NIGHT WILL BE QUIET.  THUNDERSTORMS IN EASTERN NEW
MEXICO MAY MOVE INTO NORTH TEXAS EARLY WEDNESDAY MORNING.  UNTIL
THEN WINDS WILL BE LIGHT WITH SOME HIGH CLOUDS.  59

CONVECTION HAS ALREADY DEVELOPED THIS AFTERNOON...ALONG A WEAK
CONVERGENCE ZONE IN CENTRAL TEXAS...AND ACROSS PORTIONS OF EASTERN
NEW MEXICO. SHORT TERM MODEL GUIDANCE IS IN REMARKABLE AGREEMENT ON
THE CONVECTION ACROSS WEST TEXAS DEVELOPING INTO A LARGE MCS...AND
MOVING SOUTHEASTWARD ACROSS CENTRAL TEXAS OVERNIGHT. HOWEVER...A
GREAT DEAL OF UNCERTAINTY REMAINS...ESPECIALLY GIVEN SIMILAR
CONDITIONS FORECAST FOR LAST SUNDAY. WITH THIS IN MIND...WILL PLACE
HIGHEST CHANCE POPS ACROSS WESTERN ZONES...AS MCS WILL LIKELY
PROPAGATE INTO STRONGEST LOW-LEVEL MOISTURE ADVECTION...WHICH WILL
LIKELY OCCUR WEST OF OUR FORECAST AREA. GIVEN WEAK CINH FORECAST TO
REMAIN ACROSS THE DFW/ACT REGIONS AND PROGS OF WEAK SYSTEM RELATIVE
LOW-LEVEL WINDS ACROSS THE AREA...WILL TAPER POPS TO LOW CHANCE
ACROSS THE I-35 CORRIDOR...AND KEEP ONLY SLIGHT CHANCES IN THE FAR
EAST. GUIDANCE FROM NUMEROUS MODELS /GFS-CANADIAN-UKMET/ CONTINUE TO
PAINT A WET PICTURE ACROSS NORTH TEXAS THROUGH FRIDAY. HOWEVER...
GIVEN AMOUNT OF UNCERTAINTY CONCERNING WHERE UPPER WAVES WILL TRACK
AND THE RESULTANT LOCATION OF RESIDUAL SURFACE BOUNDARIES...WILL
ONLY PLACE SLIGHT CHANCE POPS IN THE FORECAST. IN TERMS OF
TEMPERATURES...WILL FOLLOW A WARMER SOLUTION THAN WHAT HAS BEEN
FORECAST FOR THE LAST SEVERAL DAYS...AS BOTH MAXES AND MINS HAVE
BEEN WARMER THAN MOS NUMBERS.

THE EXTENDED PORTION OF THIS FORECAST APPEARS TO FAVOR A DRIER AND
WARMER PATTERN...AS ALL MEDIUM RANGE GUIDANCE IS IN AGREEMENT ON
BUILDING AN UPPER RIDGE ACROSS THE GULF OF MEXICO AND INTO TEXAS BY
THIS WEEKEND. THE LATEST GFS WANTS TO SWEEP ANOTHER FAST MOVING COLD
FRONT ACROSS THE REGION ON SUNDAY. HOWEVER...WILL WAIT FOR
ADDITIONAL CONTINUITY IN MODEL RUNS TO FORECAST COOLER TEMPERATURES
AND CHANCES OF RAIN. FOR NOW...WILL CONTINUE WITH A DRY AND SLOW
WARMING TREND THROUGH NEXT TUESDAY.
