.DISCUSSION...

MUCH OF THE REMAINING CONVECTION HAS DISSIPATED EARLY THIS AFTERNOON...AS
S AR/N LA HAS BEEN SLOW TO DESTABILIZE IN WAKE OF THE MORNING CONVECTION.
HOWEVER...RESIDUAL OUTFLOW BOUNDARY HAS REINFORCED THE WEAK STATIONARY
BOUNDARY ACROSS SOUTHCENTRAL LA INTO LOWER E TX THIS AFTERNOON...WITH
TOWERS/WEAK CONVECTION DEVELOPING ALONG THE INSTABILITY AXIS.  HOWEVER...MCV
HASN/T MOVED ALL THAT MUCH SINCE THE MORNING DISCUSSION...AND REMAINS OVER
CENTRAL AR PER SATELLITE/MOSAIC 88-D IMAGERY.  MCV/TROUGH AXIS SHOULD
CONTINUE ON A SE TRACK INTO SE AR/NE LA THIS EVENING...WITH DRIER AIR IN
THE MID AND UPPER LEVELS FILTERING IN ON THE NW FLOW.  BOUNDARY SHOULD
STILL RUN NW TO SE ACROSS E TX AND N LA SATURDAY...THUS HAVE RETAINED
SLIGHT CHANCE POPS IN VC OF THE BOUNDARY TO RESPECT INSTABILITY INCREASING
WITH THE HEAT OF THE DAY.  HOWEVER...WEAK UPPER RIDGE IN PLACE THIS AFTERNOON
FROM SOUTHERN AZ/FAR W TX...IS EXPECTED TO AMPLIFY NORTHWARD INTO SOUTHERN
CANADA DURING THE WEEKEND...THUS CAP MAY BE ENOUGH TO SUPPRESS MOST/IF NOT
ALL CONVECTION THAT MAY TRY AND DEVELOP ON IT SATURDAY.

LOOKS LIKE HOT/DRY/HUMID CONDITIONS WILL RETURN FOR MUCH OF THE NEXT
WEEK...AS THE AFOREMENTIONED RIDGE IN PLACE WILL REMAIN DOMINANT ACROSS THE
NATION/S HEARTLAND.  HOWEVER...PROGS INDICATE THAT CURRENT TROUGHING ALONG
THE E COAST WILL BECOME CUT OFF BY SUNDAY MORNING OVER THE CAROLINAS...AND
SLOWLY RETROGRADES SW ACROSS GA/AL BY EARLY NEXT WEEK.  GFS WANTS TO SHEAR
THIS SYSTEM OUT BY TUESDAY...WITH A PIECE OF ENERGY POSSIBLY TAKING UP
RESIDENCE IN THE NORTHERN GULF BY THURSDAY.  IF THIS IS INDEED THE
CASE...THEN THIS FEATURE WOULD ENHANCE SEABREEZE ACTIVITY BY LATE NEXT
WEEK...WHICH WOULD HELP SLIGHTLY RELIEVE THE MODERATE/SEVERE DROUGHT
CONDITIONS IN PLACE ACROSS MUCH OF THE REGION.  BUT FOR NOW...WILL KEEP
FORECAST DRY AND AWAIT FUTURE RUNS BEFORE CATCHING ONTO THIS SCENARIO.

HAVE TAILORED TEMPS A TAD ABOVE GUIDANCE IN THE SHORT TERM IN LIGHT OF DRY
ANTECEDENT SOIL CONDITIONS EVEN AFTER RECENT RAINS.  MOS OBVIOUSLY DOES
NOT CUE ON OUR LACK OF SOIL MOISTURE...THUS AREAS THAT DID NOT RECEIVE RAIN
THE LAST COUPLE OF DAYS WILL HAVE MORE OF A POTENTIAL TO WARM /I.E. E TX/.
THE GROUND SHOULD QUICKLY DRY OUT AGAIN IN THE NEXT COUPLE OF DAYS...WITH
MID/UPPER 90S AGAIN POSSIBLE NEXT WEEK.

PRELIMS ARE NEXT...
