.DISCUSSION...

SCATTERED SHOWERS AND THUNDERSTORMS HAVE ONCE AGAIN DEVELOPED ACROSS
THE MID-SOUTH THIS AFTERNOON. THIS CONVECTION HAS DEVELOPED ALONG A
WEAK SURFACE TROUGH WHICH BISECTS THE REGION AND IN RESPONSE TO AN
UPPER LEVEL TROUGH AXIS ALONG WITH DAYTIME HEATING. OTHER
CONVECTION FURTHER SOUTH HAS ALSO INITIATED ALONG OLD OUTFLOW
BOUNDARIES LEFT AROUND FROM CONVECTION THAT OCCURRED EARLIER THIS
MORNING. EXPECT CHANCES FOR SHOWERS AND THUNDERSTORMS TO CONTINUE
THROUGH THIS EVENING WITH A REDUCTION IN THE OVERALL COVERAGE LATER
TONIGHT WITH THE LOSS OF DAYTIME HEATING. ANY THUNDERSTORMS WILL BE
CAPABLE OF PRODUCING HEAVY RAIN (HIGH PWATS)...GUSTY WINDS...AND
DANGEROUS CLOUD TO GROUND LIGHTNING. ALTHOUGH A FEW STORMS MAY BECOME
STRONG...THINK THAT MOST WILL STAY BELOW SEVERE LIMITS...ALTHOUGH
CANNOT COMPLETELY RULE OUT AN ISOLATED PULSE SEVERE STORM IN AREAS
THAT RECEIVED GOOD HEATING AND RESULTANT POCKETS OF INCREASED
INSTABILITY. TEMPERATURES THIS AFTERNOON HAVE BEEN HELD BACK ACROSS
MOST AREAS DUE TO THE CLOUD COVER AND SCATTERED THUNDERSTORMS.

THIS WEATHER PATTERN WILL CONTINUE INTO SATURDAY...WITH THE UPPER
TROUGH AXIS REMAINING ORIENTED OVER THE AREA. EXPECT ANOTHER DAY
SIMILAR TO TODAY...WITH SCATTERED THUNDERSTORMS DEVELOPING ALONG
OLD MESOSCALE SURFACE BOUNDARIES...ESPECIALLY DURING THE MAXIMUM
HEATING OF THE DAY. THINK THAT TEMPERATURES WILL REACH INTO THE UPPER
80S AGAIN ON SATURDAY...WITH WIDE RANGES IN AFTERNOON TEMPERATURES
BASED UPON WHERE ONGOING CONVECTION EXISTS. IN ADDITION...WITH A VERY
MOIST AIRMASS IN PLACE AND PRECIPITABLE WATER VALUES NEARING 2
INCHES...CANNOT RULE OUT A HEAVY RAIN POTENTIAL WITH ANY SLOW MOVING
THUNDERSTORMS.

THE BERMUDA HIGH OFF OF THE SOUTHEAST U.S. COAST TODAY WILL BUILD
WESTWARD FOR SUNDAY AND INTO THE FIRST PART OF NEXT WEEK. THIS WILL
ALLOW FOR DRIER MID LEVEL AIR TO MOVE OVER THE AREA AND WITH UPPER
LEVEL HEIGHT RISES SHOULD LEAD TO MORE SUBSIDENCE OVER THE REGION.
ALTHOUGH DIURNAL CONVECTION CANNOT BE RULED OUT FOR THE END OF THE
WEEKEND AND EARLY NEXT WEEK...THE OVERALL CHANCES AND COVERAGE WILL
BE DIMINISHED.

AN UPPER LEVEL SHORTWAVE TROUGH NOW MOVING INTO THE PACIFIC
NORTHWEST WILL MOVE EAST THROUGH THE WEEKEND ACROSS THE NORTHERN
PLAINS AND AMPLIFY THROUGH THE BEGINNING OF NEXT WEEK. THIS WILL
HELP TO SEND A COLD FRONT TOWARDS THE AREA ON MONDAY NIGHT AND
TUESDAY. THE UPPER TROUGH WILL BEGIN TO DE-AMPLIFY BY MID-WEEK
CAUSING THE FRONT TO STALL ALONG OUR NORTHERN PERIPHERY ON TUESDAY
AND WASH OUT BY WEDNESDAY. HAVE RAISED POPS A BIT ON TUESDAY TO
ACCOUNT FOR THUNDERSTORM DEVELOPMENT IN ASSOCIATION WITH THE FRONT.
UPPER LEVEL RIDGING WILL AGAIN BUILD OVER THE AREA FOR THE END OF
NEXT WEEK WITH DRY WEATHER AND INCREASING SUMMER HEAT EXPECTED.
