.PREV DISCUSSION... (ISSUED 245 PM CDT SUN JUN 5 2005)

SHORT TERM...
A BLOB OF DRIER AIR HAS BEEN WORKING ITS WAY ACROSS WEST CENTRAL
TEXAS TODAY. DEWPOINTS AT KJCT...KSOA...AND KSJT DROPPED INTO THE
LOW 60S THIS MORNING...WITH THE DEWPOINT AT KABI HAVING DROPPED TO
63 OVER THE LAST SEVERAL HOURS. ALTHOUGH THERE HAS BEEN SOME
RECOVERY...THESE LOWER DEWPOINTS...COMBINED WITH A MID LEVEL CAP
ALREADY IN PLACE...HAVE PUSHED CIN VALUES AT 19Z WELL ABOVE 100
ACROSS THE CENTRAL AND SOUTHERN COUNTIES. CAPE VALUES THAT WERE
5000 TO 6000 YESTERDAY ARE IN THE 2000 TO 300 RANGE TODAY.
BOUNDARY WISE...WEAK COLD FRONT THAT HAD OOZED TO NEAR THE
NORTHWEST BIG COUNTRY THIS MORNING HAS STARTED TO RETREAT...ALONG
WITH SEVERAL OUTFLOW BOUNDARIES THAT WERE SEEN ACROSS THE BIG
COUNTRY THIS MORNING. ALOFT...WEAK SHORTWAVE NOTED CROSSING INTO
THE SOUTHERN ROCKIES...HEADED JUST NORTH OF DUE EAST.

WITH THE HIGH CINS ACROSS THE CENTRAL AND SOUTH...GETTING
CONVECTION TO DEVELOP ACROSS THE SOUTHERN TWO THIRDS OF THE AREA
WILL BE TOUGH. EXCEPTION MAY BE ACROSS THE BROWNWOOD AREA...WHICH
APPARENTLY MISSED THE DRY AIR PASSING OFF TO THE WEST. HIGHER
DEWPOINTS HAVE GIVEN RISE TO BETTER INSTABILITY OVER THERE AND AT
LEAST SOME CHANCE OF STORM DEVELOPMENT. BETTER RAIN CHANCES TO THE
NORTH...WHERE MOISTURE POOLING ALONG THE BOUNDARIES WILL COMBINE
WITH THE WEAKER MID LEVEL CAP. MODELS HAVE KEPT TRYING TO INITIATE
AN MCS SOMEWHERE UP ALONG THE RED RIVER VALLEY...ALTHOUGH THERE
HAS BEEN VERY LITTLE CONSISTENCY ON THE WHERE. ALREADY CARRYING
CHANCE POPS UP ACROSS THE BIG COUNTRY AND THIS LOOKS GOOD FOR NOW.

LONG TERM...
GENERAL PATTERN OF TROUGH TO THE WEST AND RIDGE TO THE EAST TO
CONTINUE...GIVING SOUTHWEST FLOW ACROSS THE SOUTHERN PLAINS. WILL
LIKELY SEE A FEW SHORTWAVES RACE ACROSS THE AREA...BUT TIMING
THESE WAVES WILL BE JUST ABOUT BE IMPOSSIBLE MORE THAN A DAY OR
TWO IN ADVANCE. BEST CHANCES LOOK TO BE FRIDAY INTO SUNDAY...WHEN
WHATS LEFT OF THE TROUGH MOVES ACROSS THE PLAINS.

.SJT WATCHES/WARNINGS/ADVISORIES...SEVERE THUNDERSTORM WATCH
UNTIL MIDNIGHT FOR FISHER...HASKELL...THROCKMORTON.
