WEAKENING FRONTAL SEGMENT ACROSS AR/TX/LA.
A FEW LIGHTNING STRIKES WILL BE POSSIBLE AS THE MIDLEVEL COLD CORE
CROSSES THE STILL RELATIVELY WARM UPPER GREAT LAKES. A FEW
THUNDERSTORMS ARE ALSO EXPECTED TODAY ACROSS S AND E TX...THOUGH THE
GREATER THUNDERSTORM COVERAGE THIS MORNING WILL REMAIN OFFSHORE OVER

WEAK SHORTWAVE TROUGH MOVING EWD FROM THE RIO GRANDE VALLEY.
OTHERWISE...MAINLY DIURNAL STORMS WILL AGAIN BE POSSIBLE ACROSS N FL
ALONG THE STALLED FRONT...AND FARTHER S INTO CENTRAL/S FL IN
ASSOCIATION WITH SEA BREEZE CIRCULATIONS.
