DISCUSSION...
UPPER LEVEL RIDGE ORIENTED W-E FROM OK THROUGH IL. AT THE SFC...SFC
RIDGE LOCATED ACROSS THE MID ATLANTIC STATES. THIS SFC RIDGE WILL BE
INFLUENCING OUR WEATHER OVER THE NEXT FEW DAYS BY ALLOWING DRIER AIR
TO WORK IN THROUGH THE LOWER LEVELS.

OTW...A WEAK SFC BOUNDARY STILL RESIDES ACROSS THE AREA THIS
MORNING. BUT OTHER THAN A FEW EXTRA MORNING CLOUDS AND PERHAPS A
STRAY AFT SHOWER/TSTM SW...THIS FEATURE SHOULD BE DISSIPATING IN THE
DAYS TO COME. AFOREMENTIONED UPPER RIDGE WILL RETREAT
SOUTHEASTWARD TOWARD THE BAHAMAS BUT THE ASSOCIATED AXIS WILL
EXTEND NW TOWARD TN. THEREBY...THE REMAINDER OF THIS WORK WEEK
LOOKS BASICALLY DRY.

FOR THE NEAR TERM TEMPS...THERMAL WITH THERMAL RIDGING IN
PLACE...AFTERNOON HIGHS WILL CONTINUE TO RUN A GOOD 5-8 DEGREES OR
SO ABOVE NORMAL. OVERNIGHT LOWS WILL BE JUST A FEW DEGREES ABOVE
NORMAL AS THE LOWER LEVELS DRY OUT JUST A TOUCH.

IN THE EXT FCST...UPPER LEVEL SHORTWAVE TO APPROACH THIS WEEKEND. A
SOUTHERLY MULTI-LEVEL WIND COMPONENT WILL RETURN AND BRING AN
INCREASE IN MOISTURE. THUS...SHOWER AND TSTM CHANCES TO RETURN.

THE EXT TEMPS CONTINUE TO LOOK WARMER THAN NORMAL AS UPPER
RIDGING...THOUGH NOT PARTICULARLY STRONG...HOLDS ACROSS THE DEEP
SOUTH.
