.DISCUSSION...

QUIET CONDITIONS CONTINUE TONIGHT ACROSS THE REGION AS HIGH
PRESSURE SETTLES IN. SIMILAR CONDITIONS AS YESTERDAY CAN BE
EXPECTED TODAY WITH NORTHERLY FLOW AT THE SURFACE AND CLEAR SKIES.
WINDS SHOULD SLOWLY WORK THEIR WAY TO SOUTHERLY BY LATE SUNDAY
INTO MONDAY...BUT MORE SUBSTANTIAL SOUTH TO SOUTHWESTERLY FLOW
SHOULD ARRIVE TUESDAY. THIS WILL KEEP THE STEADY WARMING TREND
THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK IN TACT...WITH
TUESDAY LOOKING TO BE THE WARMEST DAY WITH HIGHS IN THE LOW TO MID
90S.

THE REASON FOR THE SOUTHERLY FLOW EARLY NEXT WEEK AND WARMING IS
DUE TO THE APPROACHING TROUGH THAT WILL FINALLY BRING A GOOD
CHANCE FOR PRECIP WEDNESDAY INTO THURSDAY. THE GFS AND ECMWF AGREE
ON LOCATION OF THE TROUGH BUT THE GFS IS A BIT MORE AGGRESSIVE
WITH THE STRENGTH OF THE TROUGH OVER THE MS RIVER VALLEY. EITHER
WAY IT LOOKS LIKE MIDDLE TN SHOULD SEE SOME PRECIP LATE WEDNESDAY
INTO THURSDAY WITH LINGERING CHANCES INTO FRIDAY. THE WEEKEND IS
STILL DIFFICULT TO PINPOINT ATTM DUE TO THE DIFFERENT FLOW
SOLUTIONS BY THE LONG TERM MODELS. THE GFS HAS A TROUGH AND IS A
BIT MORE WET WHILE THE ECMWF HAS RIDGING A BIT FURTHER EAST OVER
THE REGION. BOTH MODELS HAVE SUBTLE SHORTWAVES AS WELL...SO TRYING
TO PINPOINT BETTER TIMING FOR PRECIP NEXT WEEKEND WILL HAVE TO
WAIT UNTIL THERES BETTER MODEL AGREEMENT.
