345 PM CDT MON AUG 25 2014

.DISCUSSION...
LOCAL 88DS ARE BEGINNING TO LIGHT UP WITH SCATTERED SHOWERS/STORMS
DEVELOPING IN RESPONSE TO THE ERLY WAVE CROSSING SERN LA ATTM.
EXPECT SOME OF THE NRN CONVECTION TO BEGIN DYING OFF WITH LOSS OF
HEATING THIS EVENING BUT HAVE MAINTAINED HIGHER POPS TONIGHT
CLOSER TO THE COAST WHERE LIFT/MOISTURE IS PROGGED TO REMAIN A
LITTLE BETTER. HIGHEST POPS WILL CONTINUE SPREADING WWD CLOSER TO
THE COAST AS THE WAVE CONTINUES PUSHING WWD ACROSS THE NWRN GULF
INTO TOMORROW MORNING. CONDITIONS LOOK TO IMPROVE BY TOMORROW
AFTERNOON AS DRYING ACCOMPANIES SOME RIDGING ALOFT RE-ESTABLISHING
ITSELF ESPECIALLY ACROSS THE ERN 1/2 OF THE AREA.

POST-WAVE AND THROUGH MID-WEEK MOISTURE IS PROGGED TO REMAIN
SOMEWHAT ELEVATED ESPECIALLY NEAR THE COAST WHILE THE RIDGE ALOFT
NUDGES SWD TOWARD THE REGION. FOR NOW HAVE MAINTAINED SMALL POPS
AREA-WIDE...TRENDING HIGHER FROM N-S. BY LATE IN THE WORK WEEK THE
AREA WILL BECOME UNDER A LITTLE BETTER INFLUENCE OF THE
APPROACHING WRN CONUS TROF...AND THE INCREASING MOISTURE/LIFT WILL
ALLOW FOR THE GRADUAL ELEVATION IN POPS INTO THE WEEKEND. RAIN
CHANCES WILL FINALLY WANE BY SUNDAY AS THE TROF AXIS WEAKENS AND
MOVES E OF THE AREA.

&&

.MARINE...
WINDS WILL GRADUALLY VEER AROUND TO A MORE TYPICAL SRLY DIRECTION
BY MID-WEEK AS THE WAVE MOVES WEST OF THE COASTAL WATERS AND HIGH
PRESSURE BECOMES RE-ESTABLISHED TO OUR EAST. NO FLAGS ARE
ANTICIPATED THROUGH THE PERIOD ATTM.
