STILL SEEING AREAS OF ELEVATED CU STREAMING S ACROSS WRN AND
SCNTRL AR...AROUND THE ELONGATED CENTER OF THE CLOSED LOW OVER WRN
TN/MID-SOUTH REGION. HOWEVER...THE LAST FEW 11-3.9U SATELLITE
IMAGES HAS SHOWN THIS CU FIELD GRADUALLY ERODING ON ITS WRN FLANK
ACROSS EXTREME ERN OK/SW AR...WHICH SHOULD ALLOW FOR THE CU FIELD
TO CONTINUE TO DIMINISH OVERNIGHT WITH THE DEPARTURE OF THE CLOSED
LOW. WHILE WINDS ARE NO LONGER GUSTING ACROSS THE AREA THIS
EVENING /EXCEPT FOR THE ELD/MLU AREAS/...A PRESSURE GRADIENT
REMAINS WITH WINDS GENERALLY RANGING FROM 5-10KTS AS OF 03Z. EVEN
WITH THE CLEARING SKY IN PLACE...MIXING HAS HELPED TO HOLD THE 03Z
TEMPS AT OR ABOVE 50 DEGREES OVER MUCH OF THE REGION...WITH WINDS
EXPECTED TO ONLY DROP OFF SLOWLY OVERNIGHT ONCE THE PRESSURE
GRADIENT EASES SOME. AS A RESULT...DID BUMP UP MIN TEMPS A TAD FOR
PORTIONS OF THE AREA...MAINLY OVER SW AR AND N LA. OTHERWISE...THE
REMAINDER OF THE FORECAST IS ON TRACK.
