.DISCUSSION...
ASIDE FROM THE MID AND HIGH CLOUD LAYERS OBSERVED ON IR SATELLITE
IMAGERY...VERY LITTLE REMAINS TO DISCERN THE REMNANT FRONTAL BNDRY
WHICH HAD MOVED AS FAR SOUTH AS OUR EXTREME SRN ZONES ON SUNDAY
BEFORE STALLING. AS THE GULF OPENS BACK UP TODAY DUE TO INCREASING
S/SW FLOW...EXPECT TYPICAL SUMMERLIKE CONDITIONS TO RETURN AS SEA
BREEZE CONVECTION WILL ADVANCE NWRD INTO OUR SRN ZONES LATER TODAY
WHILE A SHORT WAVE DIVING SWRD OUT OF THE SRN PLAINS THIS MORNING
WILL SERVE AS A FOCUS FOR ADDITIONAL CONVECTION OVER THE REMAINDER
OF OUR REGION THIS AFTERNOON AND EVENING. TEMPERATURES SHOULD HAVE
TIME TO RECOVER INTO THE LOWER 90S PRIOR TO THE ONSET OF SHWRS AND
TSTMS WHICH SHOULD REMAIN ISOLD TO WIDELY SCATTERED...HENCE SLIGHT
CHANCE TO LOW CHANCE POPS HAVE BEEN CARRIED THROUGH THIS EVENING.

THE UPPER LEVEL PATTERN WILL REMAIN MOSTLY UNCHANGED FOR TUESDAY
AS THE LONGWAVE TROF WILL BECOME SLIGHTLY MORE AMPLIFIED ACROSS
THE ERN HALF OF THE COUNTRY...CARVING DEEPER INTO OUR REGION WITH
ADDITIONAL SHORT WAVE PERTUBATIONS IN THE NW FLOW ALOFT. THIS WILL
ENHANCE CONVECTION DURING MUCH OF TUESDAY BEFORE THE UPPER PATTERN
FINALLY SHIFTS WITH THE TROF SLIDING EAST AND THE UPPER RIDGE OUT
WEST BECOMING MORE INFLUENTIAL. ALTHOUGH RAIN CHANCES CANNOT BE
RULED OUT ENTIRELY...THEY WILL BE LOWER FOR HEADING INTO WEDNESDAY
AND THURSDAY WITH SLIGHTLY WARMER TEMPERATURES.

BY FRIDAY...THE NEXT MAJOR SHORT WAVE WILL DIVE SWRD ACROSS THE
PLAINS IN THE NW FLOW PATTERN. THIS WILL SEND OUR RAIN CHANCES
HIGHER FOR FRIDAY AND SATURDAY WITH TEMPERATURES FALLING OFF BY A
FEW DEGREES DUE TO THE ADDITIONAL CLOUD COVER AND CONVECTION.
EXPECT HOT AND HUMID CONDITIONS MORE TYPICAL OF SUMMER TO RETURN
FOR THE LATTER HALF OF NEXT WEEKEND INTO EARLY NEXT WEEK AS HIGH
PRESSURE RIDGE BUILDS BACK ACROSS THE REGION WITH LESSER CHANCES
FOR ISOLD AFTERNOON CONVECTION. /19/
