738 PM CDT SAT JUN  5 2004

.UPDATE...THUNDERSTORMS THAT HAD DEVELOPED ALONG THE DRYLINE/OUTFLOW
BOUNDARY CONVERGENCE AREA OVER THE PERMIAN BASIN ARE ON THE WAY
DOWN. SO HAVE REMOVED MENTIONABLE POPS IN THE FIRST HALF OF THE
PERIOD FOR EVERYWHERE EXCEPT STERLING...IRION AND CROCKETT COUNTIES
WHERE THEY COULD SEE A LITTLE MEASURABLE RAIN...HOWEVER CHANCES OF
THAT ARE BEGINNING TO LOOK MEAGER.

THEN ALL EYES TURN TOWARDS THE PAN HANDLE ONCE AGAIN AS COMPLEX IS
CURRENTLY IN FULL SWING IN THAT AREA AT THIS TIME. THIS ACTIVITY IS
EXPECTED TO ONCE AGAIN MOVE INTO THE AREA 11 PM OR AFTER. WHETHER
OR NOT THE DAMAGING WIND THREAT WILL REMAIN WITH THE ACTIVITY BY
THAT TIME REMAINS TO BE SEEN. HOWEVER DID RAISE POPS FOR THE LAST
SIX HOURS OF THE TONIGHT PERIOD.

ALSO TWEAKED TOMORROW MORNINGS POPS UP A LITTLE ACROSS THE NORTHEAST
ZONES WITH THE REMAINS OF ANY ACTIVITY EXPECTED ACROSS THAT AREA AT
THE BEGINNING OF THE PERIOD.  ALSO LOWERED TONIGHTS MINS A TAD GIVEN
THAT THE DRIER HAS BEEN COOLER AT NIGHT WITH THE PRECIPTIATION AND
ANY OUTFLOW BOUNDARIES THAT PASS THROUGH ANY PARTICULAR AREA.

UPDATED PRODUCTS OUT SHORTLY.

.PREV DISCUSSION...
A FEW SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP ACROSS EASTERN
SECTIONS OF WEST CENTRAL TEXAS THIS AFTERNOON. AIRMASS WAS PRETTY
WELL WORKED OVER BY REMNANTS OF MCS THIS MORNING...BUT REMAINS MOIST
AND UNSTABLE ENOUGH FOR THESE TO CONTINUE TO DEVELOP. WE EXPECT
THUNDERSTORM ACTIVITY THIS AFTERNOON AND EARLY THIS EVENING TO BE
SOMEWHAT LIMITED ACROSS WEST CENTRAL TEXAS.

FURTHER NORTH...THUNDERSTORMS BEGINNING TO DEVELOP THIS AFTERNOON
ALONG SURFACE TROF ACROSS NORTHEAST NEW MEXICO INTO SOUTHWEST KANSAS.
THESE STORMS ARE EXPECTED TO ORGANIZE INTO ANOTHER MCS AND MOVE
SOUTHEAST TONIGHT...THROUGH AT LEAST PART OF WEST CENTRAL TEXAS. WE
WILL PUT HIGHEST POPS ACROSS THE BIG COUNTRY AND TAPER DOWNWARD
TOWARD THE SOUTHWEST.

UPPER AIR PATTERN BEGINS TO CHANGE LATE IN THE WEEKEND AS A TROF
MOVES INTO THE PACIFIC NORTHWEST...FLATTENING UPPER RIDGE OVER THE
WESTERN U.S...AND THEN DIGGING TROF OVER THE FAR WEST. WE CANNOT
RULE OUT SOME DRYLINE ACTIVITY ACROSS WESTERN PORTIONS OF WEST
CENTRAL TEXAS NEXT WEEK...BUT DONT FEEL CONFIDENT ENOUGH AT THIS
TIME TO PUT IN POPS.

.SJT WATCHES/WARNINGS/ADVISORIES...
