.DISCUSSION...
ANOTHER QUIET NIGHT ONGOING ACROSS THE CNTRL TN VALLEY THIS EARLY
WED MORNING...WITH TEMP TRENDS BEGINNING TO LOWER INTO THE 60S
RANGE. WITH DEW PTS IN THE 60S AS WELL COUPLED WITH LIGHT WINDS AND
CLEARING SKIES...SOME LIGHT FOG IS POSSIBLE THIS MORNING. AT THIS
POINT THOUGH...BELIEVE ANY FOG WILL BE MORE CONFINED TO THE FOG
PRONE AREAS AND WILL BE SHALLOW/LIGHT ENOUGH NOT TO WARRANT ANY
CONCERNS AT THIS POINT...AND SHOULD QUICKLY DIMINISH WITH THE ONSET
OF THE DAYTIME HRS. THE OVERALL WX PATTERN SHOULD THEN BE FAIRLY
STAGNANT FOR THE NEXT FEW DAYS...AS HIGH PRESSURE LAYERED ACROSS THE
MID/SRN ATLANTIC BASIN BEGINS TO GRADUALLY WEAKEN AND SHIFT EWD. THE
UPPER LEVEL FLOW PATTERN STILL HAS WEAK RIDGING BUILDING INTO THE SE
REGION FROM THE W...AND THIS AXIS SHOULD TRANSLATE EWD OVER THE NEXT
COUPLE OF DAYS HELPING TO SOLIDIFY FAIRLY BENIGN WX CONDS. AFTERNOON
TEMPS STILL LOOK TO HOVER NEAR/SLIGHTLY ABOVE SEASONAL TRENDS WHILE
OVERNIGHT LOWS RUN CLOSE TO NORMAL READINGS GOING TOWARD THE END OF
THE WORK WEEK.

THE PATTERN ACROSS THE AREA THEN LOOKS TO BECOME MORE ACTIVE HEADING
INTO THE WEEKEND PERIOD...AS THE FLOW REGIME TURNS MORE TOWARD THE
SW. LATEST GLOBAL MODEL TRENDS STILL HINT AT UPPER WAVES BEGINNING
TO AFFECT THE REGION BY EARLY SAT...AS AN UPPER TROUGH AXIS OUT OF
THE MID PLAINS SHIFTS EWD. EVEN WITH SUBTLE DIFFERENCES IN TIMING
AND STRENGTH LINGERING IN THE MODEL BIAS...MOISTURE DEPTH/INFLOW
SHOULD BEGIN TO INCREASE SIG AS RETURN FLOW DEVELOPS ACROSS THE AREA
LATE FRI/INTO SAT. CONVECTIVE PATTERNS CONTINUE TO LOOK FAIRLY SCT
ACROSS MUCH OF THE REGION THIS WEEKEND...WITH THE ONCOMING UPPER
TROUGH AXIS. THE OVERALL PATTERN MAY BEGIN TO IMPROVE SOME GOING
INTO LABOR DAY...AS THE UPPER TROUGH WEAKENS/LIFTS INTO THE NE
STATES. RAIN CHANCES THOUGH LOOK TO CONTINUE THROUGH THE HOLIDAY
BREAK...GIVEN ENOUGH LINGERING MOISTURE/PROBABLE UPPER WAVES IN
PLACE ACROSS THE REGION. SUPTROPICAL RIDGE THOUGH IN PLACE ACROSS
THE ERN GULF REGION MAY HELP LIMIT ANY ADDITIONAL PRECIP TO JUST A
SLIGHT CHC MAINLY DURING THE DAYTIME HRS GOING MORE INTO THE NEXT
WORK WEEK.
