AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
303 PM CDT SUN JUN 3 2007

.DISCUSSION...
DESPITE SLIGHTLY LOWER DEWPOINTS TODAY...CONVECTION IS GETTING AN
EARLIER START THAN YESTERDAY THANKS TO THE HELP OF BETTER UPPER
DYNAMICS IN THE FORM OF AN UPPER TROUGH DIGGING INTO NORTHERN MEXICO.
THE TROUGH HAS PUSHED THE RIDGE SLIGHTLY WEST ALLOWING FOR MORE ZONAL
FLOW ACROSS THE AREA AND THUS THE THUNDERSTORMS WILL HAVE MORE
EASTWARD MOVEMENT THAN WE SAW INITIALLY YESTERDAY. EXPECT THE SAME
RESULTS AS LAST NIGHT WITH DISCREET CELLS MERGING INTO AN MCS AND
MOVING SOUTHEAST OVERNIGHT WITH THE SEVERE THREAT DIMINISHING WITH
TIME.

LATE MONDAY WILL BE A REPEAT PERFORMANCE WITH CONTINUED
NORTHWESTERLY FLOW AND WENT AHEAD AND LEFT THE POPS IN FOR TUE NIGHT
AS I JUST DO NOT HAVE CONFIDENCE TO REMOVE RIGHT NOW...THOUGH I DO
HAVE CONCERNS THAT WE MAY BE TOO CAPPED FOR CONVECTION. WED WILL BE
HOT...DRY...AND WINDY SO IT IS A GOOD THING WE HAVE HAD PRECIP
RECENTLY TO HELP LOWER ANY FIRE DANGER THREAT. THURSDAY WILL BE HOT
AND DRY AS WELL BUT NOT AS WINDY AS THE PRESSURE GRADIENT RELAXES
AHEAD OF A WEAK FRONT APPROACHING THE AREA. AM NOT NEAR AS
ENTHUSIASTIC ABOUT THE ARRIVAL OF THE FRONT AS THE 12Z GFS SO HAVE
TRENDED CLOSER TO THE ECMWF AND WENT ABOVE GUIDANCE THE LAST FEW DAYS
OF THE FORECAST PERIOD. PROLONGED SOUTHWESTERLY UPPER FLOW IS NOT
CONDUCIVE TO BRINGING A FRONT INTO OUR CWA...AND IF IT DOES IT SHOULD
MAKE A QUICK EXIT BACK NORTH.
