.AVIATION...
A MESSY SATURDAY AFTERNOON INTO SUNDAY MORNING THAT WILL BE
HIGHLIGHTED WITH PERIODS OF HEAVY RAIN AND CEILINGS/VISIBILITIES
LOWERING TO IFR. BETWEEN HEAVY RAIN EPISODES...GENERALLY LIGHT
RAIN AND CEILINGS THAT WILL FLUCTUATE BETWEEN IFR AND LOW END
MVFR. AS A COASTAL LOW RIDES UP ALONG THE COASTLINE...A
STRENGTHENING LOW LEVEL JET WILL INCREASE JUST-OFF-THE-SURFACE
SOUTHEAST BACKING (NORTH)EAST WINDS TO 15 TO 25 KNOT MAGNITUDES.
LOWER 2K WIND SHEAR SHOULD NOT BE AN ISSUE AS THE DIFFERENCE
BETWEEN 020 AND SFC WIND SHOULD BE AT OR UNDER 10 KNOTS. AS THE
LOW MOVES EAST OF THE REGION SUNDAY AFTERNOON...MODERATE LOWER

..DANGEROUS MAJOR STORM EVENT TO MOVE THROUGH SOUTHEAST TEXAS
WITH THE GREATEST THREAT TONIGHT THROUGH SUNDAY MORNING...

DISCUSSION...
THREAT FOR HEAVY RAINFALL AND FLASH FLOODING CONTINUES ACROSS SOUTHEAST
TEXAS FOR LATE TODAY AND ON THROUGH THE OVERNIGHT HOURS. RECORD HIGH
MOISTURE LEVELS ARE HELPING TO GENERATE LARGE AREAS OF SHOWERS WITH
MAINLY LIGHT TO MODERATE RAINS SO FAR. RAINFALL TOTALS FROM INCREASING
SHOWER AND THUNDERSTORM COVERAGE OF 4 TO 6 INCHES TO THE NORTH OF A
LINE FROM COLUMBUS TO CLEVELAND AND 6 TO 12 INCHES TO THE SOUTH OF
THAT LINE ARE ANTICIPATED WITH LOCALLY HIGHER AMOUNTS POSSIBLE AS
LOW PRESSURE DEVELOPS NEAR OR JUST OFF THE SOUTH TEXAS COAST AND
MOVES TOWARD OUR AREA. IN ADDITION TO THE HEAVY RAINFALL THREAT...
THERE IS A POSSIBILITY OF STORM ROTATION THAT COULD LEAD TO FUNNEL
CLOUDS AND/OR TORNADOES. THIS DANGEROUS STORM SYSTEM WILL ALSO PRODUCE
INCREASING WINDS AND SEAS NEAR/ALONG THE COAST BOTH AHEAD OF THIS
STORM TODAY AND TONIGHT AND BEHIND THIS STORM ON SUNDAY.  42

PREV DISCUSSION... /ISSUED 648 AM CDT SAT OCT 24 2015/

DISCUSSION...
12Z TAF DISCUSSION IN AVIATION SECTION.

AVIATION...
RADAR SHOWING CONVECTION WORKING INTO KCLL THIS MORNING WITH A
FEW SHOWERS ACROSS OTHER SE TX TERMINALS. FRONTAL BOUNDARY WAS
NOTED TO THE NORTH OF THE AREA AND PUSHING SOUTHWARDS WITH OUTFLOW
FROM LAST NIGHTS STORMS OVER C TX. UPDATED KCLL TAF TO INCLUDE
MENTION OF TSRA TO START. OVERALL MESOSCALE MODELS ARE NOT DOING
WELL TO START WITH POSITION OF CURRENT CONVECTION. STILL LOOKS
LIKE SOME UPSCALE CONVECTIVE DEVELOPMENT AND ORGANIZATION FROM
14-18Z THIS MORNING WITH TSRA POSSIBLE AREA WIDE AFTER 18Z. CIGS
HAVE STARTED OUT MVFR/VFR FOR MOST TERMINALS BUT LIKELY DECREASE
TO IFR LATER THIS AFTERNOON WITH THE ONSET OF CONVECTION.

HEAVIEST RAINFALL SHOULD OCCUR OVERNIGHT AND WILL KEEP IFR CIGS
AND MVFR LEVEL VISIBILITY. HARD TO KNOW HOW LOW VISIBILITY WILL GO
AT THIS TIME BUT COULD SEE VISIBILITY IN THE 1-2 MILE RANGE WITH
STRONGER CONVECTION. MAIN QUESTION WILL BE WHEN HEAVY RAINFALL END
AND CIGS BEGIN TO IMPROVE. TRY TO SHOW AN IMPROVING TREND IN THE
09-18Z SUN TIME FRAME BUT THIS MAY BE DOUBTFUL. MAY NOT BE UNTIL
AFTER 18Z SUN THAT CIGS BEGIN TO IMPROVE AS SURFACE LOW MOVES
EAST.

SURFACE LOW MOVING OUT OF S TX TOWARDS SW LA WILL BE A MAIN
CONCERN FOR STRONG WINDS. MODELS SHOWING MUCH STRONGER WINDS ALONG
THE COAST THAN PREVIOUS TAFS AND COULD SEE 20G30KT AT
KGLS/KLBX/KHOU AFTER 09Z TONIGHT. THUNDERSTORM INDUCED WIND GUSTS
MAY REACH 30 KNOTS WITH OUTFLOW. 39

PREV DISCUSSION... /ISSUED 444 AM CDT SAT OCT 24 2015/

DISCUSSION...
ONE LAST QUIET NIGHT FOR SOUTHEAST TEXAS BEFORE A RATHER HAIRY 48
HOUR PERIOD UNFOLDS ACROSS THE REGION AS A POWERFUL SURFACE LOW
MOVES ALONG THE UPPER TEXAS COAST. EARLY MORNING WATER VAPOR
IMAGERY DEPICTED A MID LEVEL TROUGH MOVING ACROSS NORTHERN
MEXICO...WITH AN EXPANSIVE PACIFIC MOISTURE PLUME FROM HURRICANE
PATRICIA STREAMING OVER TEXAS AHEAD OF IT. SUBJECTIVE 05Z SURFACE
ANALYSIS SHOWED TWO DISTINCT BOUNDARIES DRAPED ACROSS TEXAS. THE
FIRST WAS AN ADVANCING COLD FRONT PUSHING SOUTH OUT OF THE TEXAS
PANHANDLE AND THE SECOND WAS A STATIONARY FRONT DRAPED FROM NEAR
DRT NORTHEAST TOWARDS ACT.

DIFFLUENT UPPER WINDS OVERSPREADING THE STATIONARY FRONT IS
RESULTING IN A TRAINING LINE OF SHOWERS AND THUNDERSTORMS
STRETCHING FROM PORTIONS OF SOUTHWEST TEXAS INTO NORTHEAST
TEXAS... WITH AN ANOMALOUSLY MOIST AIRMASS CONTRIBUTING TO A
WIDESPREAD HEAVY RAINFALL THREAT. ANYWHERE FROM 8 TO OVER 14
INCHES OF RAINFALL HAS BEEN OBSERVED ACROSS PARTS OF CENTRAL AND
NORTH TEXAS OVER THE PAST 24 HOURS...AND THE HEAVY RAINFALL
THREAT WILL SHIFT SOUTH THROUGH THE DAY TODAY TOWARDS SOUTHEAST
TEXAS AS THE MID LEVEL TROUGH APPROACHES FROM THE WEST...PEAKING
ON SUNDAY.

HURRICANE PATRICIA HAS WEAKENED SIGNIFICANTLY SINCE MAKING
LANDFALL ON MEXICO/S PACIFIC COAST LAST NIGHT...A CATEGORY 2
STORM AS OF 06Z...AND IS EXPECTED TO CONTINUE TO WEAKEN AS IT
TREKS NORTHEAST ACROSS MEXICO TODAY. HOWEVER...REMNANT ENERGY FROM
PATRICIA IS EXPECTED TO PHASE WITH THE MID LEVEL TROUGH OVER
NORTHERN MEXICO LATER TODAY AND INDUCE SURFACE CYCLOGENESIS OVER
SOUTHERN TEXAS. THIS SURFACE LOW WILL SHIFT NORTHEAST AHEAD OF THE
APPROACHING TROUGH...TRACKING ROUGHLY ALONG THE TEXAS COASTLINE
TODAY THROUGH SUNDAY. DETERMINISTIC AND ENSEMBLE GUIDANCE
SOLUTIONS ARE IN FAIRLY GOOD AGREEMENT REGARDING THE TRACK OF THIS
LOW... WITH THE CENTER OF THE LOW REACHING THE MIDDLE TEXAS COAST
THIS EVENING AND THE UPPER TEXAS COAST BY SUNDAY MORNING. THE LOW
IS EXPECTED TO PUSH NORTHEAST OF THE REGION TOWARDS LOUISIANA LATE
SUNDAY NIGHT INTO MONDAY MORNING AS THE MID LEVEL TROUGH SWINGS
OVERHEAD.

FOR TODAY...ONGOING THUNDERSTORM ACTIVITY OVER NORTH AND CENTRAL
TEXAS IS EXPECTED TO SAG SOUTHWARD THROUGH THE REMAINDER OF THE
MORNING HOURS... PUSHING INTO THE NORTHERN COUNTIES THROUGH THE
REMAINDER OF THE MORNING. WHILE THIS HAPPENS SHOWERS AND
THUNDERSTORMS WILL ALSO BEGIN TO OVERSPREAD THE REGION FROM THE
WEST AS 250 MB WIND DIVERGENCE INCREASES ACROSS THE AREA...
BEGINNING IN THE WESTERN COUNTIES IN THE 5 TO 8 AM TIMEFRAME.
EXPECT COVERAGE TO INCREASE ALONG THE INTERSTATE 45 CORRIDOR 7 TO
10 AM...WITH NUMEROUS SHOWERS AND THUNDERSTORMS IN PLACE ACROSS
THE REGION AROUND 1 PM. SHOWER AND THUNDERSTORM ACTIVITY IS
EXPECTED TO BE ALMOST CONTINUOUS THROUGH THE REMAINDER OF THE
AFTERNOON AND INTO SUNDAY MORNING AS THE SURFACE LOW MOVES TOWARDS
THE REGION.

HEAVY RAIN LEADING TO DANGEROUS FLASH FLOODING WILL BE THE MAIN
THREAT TODAY...TONIGHT...AND SUNDAY. A VERY MOIST...TROPICAL
AIRMASS WILL BE SUCKED INTO THE REGION AS THE SURFACE LOW
INTENSIFIES WITH GUIDANCE ADVERTISING 850 MB INFLOW INCREASING TO
40 TO NEARLY 50 KNOTS ACROSS THE UPPER TEXAS COAST BY SUNDAY
MORNING. THE 00Z SOUNDING OUT OF BROWNSVILLE REPORTED A 2.49 INCH
PRECIPITABLE WATER VALUE...WHICH EXCEEDS THE 1980-2009 CLIMATOLOGICAL
RECORD FOR THIS TIME IN OCTOBER. THIS EXCESSIVELY MOIST AIR WILL
BE TRANSPORTED NORTH INTO SOUTHEAST TEXAS AS THE SURFACE LOW
APPROACHES AND INTENSIFIES...AND RAISES CONCERNS FOR RAINFALL
TOTALS RANGING FROM 3 TO 6 INCHES OVER THE NORTHERN COUNTIES TO
ANYWHERE FROM 6 TO 12 INCHES SOUTH OF A COLUMBUS TO CLEVELAND
LINE. EXCELLENT LOW LEVEL CONVERGENCE /40 TO 50 KNOT SOUTHERLY
WINDS COLLIDING WITH 35 TO 35 KNOT NORTHEASTERLY WINDS/ APPEARS TO
SET UP ALONG THE HIGHWAY 59 CORRIDOR EARLY SUNDAY MORNING... AND
THIS WILL MAKE LATE TONIGHT INTO EARLY SUNDAY MORNING /GENERALLY
BETWEEN 9 PM TONIGHT AND 7 AM SUNDAY/ ONE OF THE MOST DANGEROUS
TIMES FOR HEAVY RAIN AND FLASH FLOODING. LOCALLY HIGHER RAINFALL
AMOUNTS WILL CERTAINLY BE POSSIBLE TODAY THROUGH MONDAY AND WOULD
NOT BE SURPRISED TO SEE ISOLATED MAXIMA NEARING 15 INCHES.

A SECONDARY THREAT OF A TORNADO OR OR TWO OR DAMAGING WIND GUSTS
WILL ALSO EXIST AHEAD OF THE SURFACE LOW FROM THE AFTERNOON INTO
THE OVERNIGHT HOURS ALONG THE UPPER TEXAS COAST. THE STORM
PREDICTION CENTER HAS PLACED THE UPPER TEXAS COAST UNDER A
MARGINAL RISK FOR SEVERE THUNDERSTORMS TODAY. INSTABILITY WILL
REMAIN LARGELY LIMITED...BUT STRONG LOW LEVEL SHEAR OVER THE
COASTAL COUNTIES WILL ENCOURAGE BRIEF UPDRAFT ROTATION.

RAIN CHANCES WILL GRADUALLY TAPER OFF OVERNIGHT SUNDAY INTO
MONDAY MORNING AS THE LOW DEPARTS...AND DEPENDING ON THE SPEED OF
THIS FEATURE MAY EXIT THE REGION MORE SLOWLY OR QUICKLY THAN
CURRENTLY ADVERTISED. FOR MONDAY AND BEYOND...A RELATIVELY DRY
PERIOD IS EXPECTED AS QUASI-ZONAL FLOW ALOFT BECOMES ESTABLISHED.
RAIN CHANCES RETURN HOWEVER LATE IN THE WEEK AS ANOTHER MID/UPPER
TROUGH APPROACHES THE REGION FROM THE WEST...BRINGING A POSSIBLY
WET HALLOWEEN FOR SOUTHEAST TEXAS. 14

&&

MARINE...
STRONG SE WINDS WILL CONTINUE TODAY AS LOW PRESSURE FORMS IN S
TEXAS. PRESSURE GRADIENT SHOULD INCREASE ALONG THE TX GULF THIS
AFTERNOON WITH A LONG SE FETCH OF WINDS. THIS WILL MAINTAIN SMALL
CRAFT ADVISORY CONDITIONS. SURFACE LOW PRESSURE SHOULD TRACK JUST
ALONG THE COAST TONIGHT AND INTO SUNDAY. WINDS COULD CERTAINLY
INCREASE TO AROUND 30KTS WITH GUSTS TO 40KTS. SEAS SHOULD INCREASE
TO AROUND 10-14 FEET SUNDAY MORNING AND THEN GRADUALLY DECREASE IN
THE AFTERNOON AS THE SURFACE LOW MOVES EAST. A GALE WARNING WILL BE
IN EFFECT FROM 03Z SUNDAY THROUGH 12Z MONDAY FOR THE OFFSHORE
WATERS. MATAGORDA AND GALVESTON BAYS MAY APPROACH GALES AND MAY NEED
TO UPGRADE FROM A SMALL CRAFT ADVISORY TO GALE.

STRONG OFFSHORE WINDS ARE EXPECTED MONDAY AS THE SURFACE LOW MOVES
EAST. ADVISORIES MAY BE NEEDED MONDAY FOR THE OFFSHORE WINDS MAINLY
FOR THE WATERS OUT 20-60NM. 39

&&

COASTAL IMPACTS...
TIDE LEVELS ARE ALREADY RUNNING AROUND 2 FEET ABOVE ASTRONOMICAL
TIDES. HIGH TIDES AT GALVESTON BAY ENTRANCE START AROUND 15Z
THROUGH ABOUT 21Z TODAY AND WATER LEVELS COULD REACH 3.5-3.8 FT
ABOVE MLLW. WITH THE INCREASED WINDS AND SURFACE LOW TONIGHT...
BASED ON ESTOF...WATER LEVELS COULD REACH CLOSE TO 4.8 FT ABOVE
MLLW OR NEARLY A FOOT HIGHER THAN THE LAST FEW DAYS IN WHICH THERE
WERE IMPACTS ALONG BOLIVAR PENINSULA AND HIGHWAY 87. LOOK FOR
WATER LEVELS TO PEAK FROM MIDNIGHT TO 6AM SUNDAY AND REMAIN
ELEVATED THROUGH THE AFTERNOON SUNDAY. A COASTAL FLOOD WARNING
WILL BE IN EFFECT FROM THIS MORNING THROUGH SUNDAY EVENING TO
COVER COASTAL FLOOD THREAT.

ALONG WITH THE COASTAL FLOOD THREAT THERE WILL BE A HIGH RISK OF
RIP CURRENTS ON GULF FACING BEACHES. PEOPLE AND THRILL SEEKERS
ARE ENCOURAGED TO STAY OUT OF THE WATERS AND OBSERVE THE WAVE
ACTION FROM A SAFE DISTANCE. 39
