MOISTURE WILL BE ON A SLOW INCREASE OVER THE REGION AS SUBTROPICAL
JETLET MOVES NORTH OUT OF MEXICO AND RIGHT REAR ENTERS THE AREA IN
EARLY AM...AND OFF TO THE NORTH-NORTHEAST BY LATE AFTERNOON.  THIS
ALONG WITH THE WARM FRONT DRIFTING NORTHWARD...AND THE SEABREEZE

OVER THE SOUTHERN HALF OF THE REGION FOR THU.  LIGHT WINDS WILL
BECOME NORTHEAST AGAIN TONIGHT AND THEN COME AROUND FAIRLY ABRUPTLY

EXPECT ANOTHER ROUND OF THUNDERSTORMS BUT WILL DEPEND ON TIMING OF
UPPER FEATURES FOR ANY SIGN OF ORGANIZATION SO WILL LEAVE THIS TO
