ANOTHER COMPLICATED FORECAST TODAY WITH STRONG CONVECTION
DEVELOPING OVER THE WESTERN ZONES AND DENSE SEA FOG PLAGUING THE
COASTAL ZONES. AT 15Z...A SURFACE TROUGH EXTENDED FROM NEAR WACO
SOUTHWARD TO ALICE. CONVECTION HAS BEEN DEVELOPING AND
INTENSIFYING NEAR THIS FEATURE THIS MORNING. AS THE TROUGH EDGES
EAST...AM EXPECTING LOW LEVEL CONVERGENCE TO STRENGTHEN. UPPER
LEVEL WINDS WILL ALSO BECOME MORE FAVORABLE AS SE TX FALLS INTO A
RIGHT REAR QUAD. TEXAS A AND M LAUNCHED A 15Z SOUNDING AND THE
SOUNDING SHOWS FAIRLY STEEP MID LEVEL LAPSE RATES AND LI VALUES OF
-4. WILL MAINTAIN LIKELY POPS AND ADD SEVERE WORDING FOR AREAS
ALONG AND NORTH OF I-10. WILL MAINTAIN THE DENSE FOG ADVISORY FOR
GALVESTON AND CHAMBERS COUNTIES DUE TO THE SEA FOG. THERE WILL
PROBABLY BE SEVERAL UPDATES DURING THE DAY. 43

.PREV DISCUSSION... /ISSUED 436 AM CST WED FEB 15 2012/
DISCUSSION...
SHOULD BE AN ACTIVE DAY ACROSS SE TX AS A COLD FRONT MOVES IN FROM
THE NORTH. AS PER CURRENT TRENDS PCPN ALREADY GETTING STARTED OVER
THE NEARSHORE WATERS WITH STRONG WAA ALREADY IN PLACE. WHILE THESE
RAINS ARE A GIVEN SOMEWHAT...CONFIDENCE REMAINS LOW WITH THE POSS-
IBILITY OF SEVERE WX WITH THIS ACTIVITY. PROGS OF STRONG LIFT JUST
AHEAD OF/ALONG THE FRONT ITSELF...COMBINED WITH ABUNDANT LOW-LEVEL
MOISTURE/DEEP IN-FLOW SHOULD HELP TO PRODUCE TSRAS THIS AFTN. HOW-
EVER THE BEST JET DYNAMICS APPEAR TO BE JUST NNE OF THE REGION AND
THEN THERE ARE THE QUESTIONS OF HOW UNSTABLE OUR AIRMASS CAN ACTU-
ALLY GET WITH THE PERSISTENT CLOUDS. SO BASED ON THESE CONCERNS...
WILL LIKELY KEEP THE MENTION OF SEVERE OUT OF THE ZONES TODAY WITH
FURTHER ELABORATION IN THE HWO.
THE BREAK IN BETWEEN WX SYSTEMS EXPECTED TO BE BRIEF AS MODELS ARE
STILL INSISTENT/CONSISTENT WITH THE DEVELOPMENT/PASSAGE OF THE UP-
PER LEVEL TROF FROM THE WEST AND A SFC COASTAL LOW FROM THE SW FOR
FRI/FRI NIGHT/SAT. AT THIS TIME...DYNAMICS DO APPEAR SLIGHTLY MORE
FAVORABLE FOR STRONG/SEVERE TSRA DURING THIS PERIOD WHEN COMPARING
WITH THE ONE TODAY. BUT HAVING SAID...THAT THERE IS STILL A LOT OF
WX TO BE HAD BETWEEN NOW AND THEN. SHOULD THESE GRAND SCHEMES COME
TOGETHER...A DRY/QUIET WEEKEND MAY BE ON TAP AS ALL THESE FEATURES
EXIT OFF TO THE EAST. BUT WITH THIS RATHER ATYPICAL LA NINA WINTER
PATTERN IN PLACE THE ACTIVE SRN STREAM JET IS FCST BE BACK BY MON.
41
MARINE...
SOUTHEAST WINDS WILL BECOME SOUTHERLY TODAY AS THE LOWER PRESSURES
ACROSS WEST TEXAS MOVE EAST. PATCHY FOG WILL BE POSSIBLE MAINLY IN
THE GALVESTON BAY AREA THIS MORNING. SHOWERS WILL BE INCREASING IN
COVERAGE OVER THE GULF WATERS AND BAYS TODAY WITH ISOLATED
THUNDERSTORMS. A PACIFIC COLD FRONT WILL REACH THE COAST AFTER 9 PM
AND LEADING TO NORTHERLY WINDS OF 10 TO 15 KNOTS. STILL NOT A CLEAR
PICTURE ON THE COASTAL LOW SCENARIO THAT MODELS HAVE BEEN PAINTING
FRIDAY AND SATURDAY. GENERALLY NORTHEAST WINDS INCREASING THEN THE
LOW MOVES THROUGH AND NORTHWEST WINDS DEVELOP BUT THE RECENT MODEL
TRENDS HAVE BEEN WEAKER WITH THE WINDS AND HAVE JUST TWEAKED THE
PREVIOUS WINDS DOWN A FEW KNOTS UNTIL THE MODELS HOPEFULLY COME INTO
BETTER AGREEMENT. SHOULD REACH SCEC/SCA CONDITIONS ON SATURDAY ON
THE BACK SIDE OF THE SYSTEM.
45
AVIATION...
CIGS CONTINUE TO SLOWLY LOWER OVER THE AREA WITH MOST NOW 400-900FT.
A FEW LIGHT SPRINKLES AS WELL BUT WITH THE APPROACHING UPPER JET AND
THE INCREASING MOISTURE EXPECT SHRA TO DEVELOP AND MOVE THROUGH THE
AREA BY LATE MORNING AND THEN MAY SWITCH OVER WITH A FEW
THUNDERSTORMS ESPECIALLY AFTER 19Z. HAVE ADDED TEMPO SHOWERS FOR
ROUGHLY THE 19-23Z TIMEFRAME WITH THE ARRIVAL OF THE BEST LIFT AND
THE SLOW EASTWARD PROGRESSION OF THE COLD FRONT AND PREFRONTAL
TROUGHING. CIGS MAY DROP AGAIN FOR HOU/SGR/LBX/GLS THIS EVENING
BEFORE THE FRONT FINALLY COMES THROUGH AND TAKES THE LL MOISTURE.
