.MARINE...
STORMS MOVING INTO THE NEARSHORE WATERS AND SHEAR/INSTABILITY OVER
THE WATER LOOKS SUFFICIENT FOR STRONG TO SEVERE STORMS THIS MORNING.
SEVERE THUNDERSTORM WATCH WAS EXPANDED AND EXTENDED TO 6 AM TO
INCLUDE THE GULF WATERS. WINDS TODAY SHOULD BECOME SOUTHWESTERLY AND
WESTERLY INCREASING AS SURFACE LOW DEEPENS MOVING OFF TO THE EAST.
WINDS LATE AFTERNOON/TONIGHT QUICKLY INCREASE TO 20-30 KNOTS WITH
GUSTS OF 30-45 KNOTS. GALE WARNING IN EFFECT TONIGHT. WINDS
GRADUALLY COMING DOWN WEDNESDAY AFTERNOON AND EVENING.

.AVIATION...
SEA FOG AT GLS IS GONE AND SHOULDN'T RETURN. MAIN ISSUE IS THE LARGE
SWATH OF RAIN/SHOWERS/TSRA MOVING THROUGH THE REGION THIS MORNING.
MORE SHOULD DEVELOP THIS AFTERNOON BUT BE SPOTTIER IN COVERAGE.
EXPECT VISIBILITIES TO DROP INTO IFR WITH THE STRONGER STORMS AND
WIDESPREAD CIGS OF 500-1500 OVC. EASTERLY WINDS SHOULD BECOME
WESTERLY AND NORTHWESTERLY LATE THIS MORNING AND EARLY THIS
AFTERNOON. STRONG GUSTY NORTHWESTERLY WINDS SET UP MID TO LATE

NORTHWESTERLY FLOW INCREASING AND SLOWLY DRYING OUT BY LATE
AFTERNOON. MODERATE NORTHWESTERLY WINDS OVERNIGHT AND WEDNESDAY
WITH RH VALUES DIPPING INTO THE MID 20 TO 30 PERCENT RANGE.

.PREV DISCUSSION... /ISSUED 447 AM CST TUE FEB 23 2016/

DISCUSSION...
MCS MOVING INTO SE TX THIS MORNING WITH THE STRONGEST STORMS OVER
THE MORE SRN FRINGES OF THIS SYSTEM. COORDINATION WITH SPC/CRP TO
EXTEND/EXPAND THE ORIGINAL WATCH KEEPS THE GREATEST THREAT(S) FOR
SEVERE WX ACROSS THE SW PORTIONS OF OUR CWA THROUGH SUNRISE. PRO-
SPECTS FOR ADDITIONAL ACTIVITY LATER TODAY COULD BE LIMITED GIVEN
THE LACK OF INSTABILITY IN THE WAKE OF THIS MORNINGS STORMS. HOW-
EVER WILL KEEP POPS ON THE HIGH SIDE THROUGH THIS AFTN AS WE WILL
STILL HAVE THE MAIN UPPER LOW MOVING ACROSS THE REGION.

NOT A LOT OF ISSUES WITH THE FCST AFTER TODAY AS THE BUILDING UP-
PER RIDGE FROM THE WEST HELPS TO DRY AND COOL THINGS OFF BY WEDS.
A WEAK COLD FRONT LATE THUR SHOULD HELP TO REINFORCE THIS AIRMASS
ACROSS SE TX THROUGH THE REST OF THE WEEK. THE FLATTENING OF THIS
UPPER RIDGE OVER THE WEEKEND WILL COINCIDE WITH THE RETURN OF ON-
SHORE WINDS BUT LOW-LEVEL MOISTURE COULD REMAIN LIMITED UNTIL MON
OR SO. THEREAFTER LONG RANGE MODELS BEGIN TO DIVERGE A BIT. ECMWF
WARMER THAN GFS BUT BOTH HINTING THAT ISO/SCT STORMS POSSIBLE MON
AND TUES AS ANOTHER COLD FRONT MOVES IN FROM THE NORTH. 41
