AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
1201 PM CST SAT JAN 16 2016

.AVIATION...
FOR THE 18Z TAFS... MAIN AVIATION CONCERNS CENTER AROUND RA/TSRA
NEAR THE TERMINALS THIS AFTERNOON... INCREASING NORTHERLY WINDS
THIS AFTERNOON AND EVENING... AND LOWERING CEILINGS OVERNIGHT.

SHOWERS AND THUNDERSTORMS THIS AFTERNOON CONTINUED TO FOCUS ALONG
A DEVELOPING SURFACE LOW LOCATED SOUTHWEST OF MATAGORDA BAY... AND
ARE EXPECTED TO PUSH NORTHEASTWARD ALONG THE UPPER TEXAS COAST AS
THE LOW LIFTS THIS AFTERNOON. SHORT TERM GUIDANCE HAS STRUGGLED TO
RESOLVE THE NORTHWARD EXTENT OF THIS CONVECTION. WITH LATEST
RADAR/LIGHTNING TRENDS SHOWING AT LEAST SOME ELEVATED INSTABILITY
BEING REALIZED AS FAR NORTH AS THE INTERSTATE 10 CORRIDOR
EAST/SOUTHEAST OF KSAT AS A MID LEVEL SHORTWAVE MOVES ACROSS
SOUTHERN TEXAS... HAVE ADDED VCTS/TSRA MENTIONS FOR ALL TERMINALS
FOR KIAH AND SOUTH. ANTICIPATE NORTHWARD EXTENT OF CONVECTION TO
SHIFT SOUTHWARD WITH TIME AS THE SURFACE LOW DEPARTS /WITH
MAJORITY OF IMPACTS TO KGLS AND KLBX/... BUT MAY NEED TO AMEND FOR
TEMPO MENTIONS OF TSRA FOR THE HOUSTON TERMINALS SOMETIME BETWEEN
21 AND 02Z DEPENDING ON TRENDS.

AS SURFACE LOW MOVES FARTHER INTO THE GULF... AN INCREASING
SURFACE PRESSURE GRADIENT AS A COLD FRONT APPROACHES WILL RESULT
IN NORTHERLY WINDS 10 TO 15 KNOTS AT THE TERMINALS FOR MOST OF THE
NIGHT. WINDS MAY APPROACH 20 KNOTS /WITH STRONGER GUSTS POSSIBLE/
FOR THE COASTAL TERMINALS TONIGHT. AFTER THE FRONT PASSES...
MOISTURE TRAPPED BENEATH THE FRONTAL INVERSION LOOKS TO RESULT IN
MVFR CEILINGS FOR THE SOUTHEAST TEXAS TERMINALS GENERALLY BETWEEN
02 AND 12Z... WITH IMPROVEMENT TO VFR AND DECREASING WINDS AT ALL
SITES SUNDAY MORNING.

.PREV DISCUSSION... /ISSUED 1004 AM CST SAT JAN 16 2016/

DISCUSSION...
TEXAS STORM SYSTEM WILL BE RACING EASTWARD ACROSS THE STATE TODAY.
AREAS OF MAINLY LIGHT RAIN HAVE ALREADY BEGUN TO DEVELOP ACROSS THE
AREA...AND MORE VIGOROUS ACTIVITY IS BEGINNING TO FORM TO THE WEST
OF THE MATAGORDA BAY AREA AND OFF THE LOWER AND MIDDLE TEXAS COASTS.
EXPECT ACTIVITY TO INCREASE IN COVERAGE AND INTENSITY THE REST OF
THE MORNING AND INTO THIS AFTERNOON. SOME OF THE STRONGER STORMS
WILL HAVE THE POTENTIAL TO BECOME SEVERE WITH LARGE HAIL THE PRIMARY
SEVERE WEATHER THREAT GENERALLY ALONG AND SOUTH OF INTERSTATE 10.
CLOSER TO THE COAST AND OFFSHORE...LARGE HAIL ALONG WITH STRONG WIND
GUSTS AND WATERSPOUTS ARE POSSIBLE.  42

PREV DISCUSSION... /ISSUED 332 AM CST SAT JAN 16 2016/

DISCUSSION...
BASE OF UPPER TROF NOW APPROACHING THE BIG BEND AREA WILL MAKE
ITS WAY ESE AND ACROSS SE TX AND THE UPPER TX COASTAL WATERS
TODAY. EXPECT THIS DISTURBANCE TO TRIGGER SOME SHRA/TSRA AROUND
THE MATAGORDA BAY AREA DURING THE LATE MORNING HOURS...THEN
EXPAND IN COVERAGE ACROSS THE SOUTHERN HALF OF THE CWA AND
OFFSHORE AS IT MOVES QUICKLY EASTWARD DURING THE AFTERNOON. SFC
LOW IS FCST TO DEVELOP SOMEWHERE NEAR OR OFFSHORE THE MATAGORDA
BAY AREA. DEPENDENT AS TO WHERE THIS OCCURS...THERE IS SOME
UNCERTAINTY REGARDING WHETHER THE WARM SECTOR WILL BRIEFLY MAKE IT
INLAND OR NOT ALLOWING FOR SOME SFC BASED CONVECTION. LAPSE RATES
DO STEEPEN ENOUGH ALOFT...HOWEVER...WHEREAS HAIL WILL STILL BE A
THREAT WITH ANY STRONGER ELEVATED STORMS THAT DO DEVELOP. FAVORED
AREA TO KEEP AN EYE ON WOULD MOST LIKELY BE ALONG/SOUTH OF THE
I-10 CORRIDOR. AM FAIRLY CONFIDENT THERE WILL BE SOME STRONG CELLS
IN OUR MARINE AREA THIS AFTERNOON WHERE HAIL...WINDS AND WATERSPOUTS
COULD ALL BE IN PLAY. TIME PERIOD (FROM WEST-TO-EAST) PROBABLY
BETWEEN 10AM-5PM.

FRONT WILL FILL IN BEHIND THE PRECIP. THERE IS SOME INDICATION IN
FCST SOUNDINGS THAT SOME MOISTURE/CLOUDS LINGER BELOW LLVL INVERSION
INTO MID MORNING SUNDAY. BUT SE TX & HOUSTON AREA WILL BE
PRECIP-FREE FOR ANY OUTDOOR ACTIVITIES GOING ON.

PROGRESSIVE PATTERN LOOKS TO CONTINUE WITH ANOTHER TROF PASSING OVERHEAD
SUNDAY NIGHT & MONDAY MORNING. SHOULD BE PRECIP-FREE AS LOCAL ATMOS WILL
BE MOISTURE STARVED. ONSHORE WINDS RESUME BY TUE ALLOWING FOR A
GRADUAL MOISTENING/WARMING TREND. MEDIUM RANGE GUIDANCE...ALTHOUGH
THERE'S SOME EXPECTED MINOR DIFFERENCES...ARE IN MUCH BETTER AGREEMENT
REGARDING PATTERN DURING SECOND HALF OF NEXT WEEK THAN WHAT WE
WERE SEEING LAST NIGHT. RAIN CHANCES WILL PROBABLY RETURN WED
FOLLOWED BY THE NEXT FRONT THAT'LL BE PENCILED IN FOR THURSDAY.

MARINE...
NOT A LOT OF ISSUES FOR THE MARINE WATERS THIS MORNING WITH A COOL
AND DRY AIRMASS OVER THE REGION. HOWEVER WE ARE STILL EXPECTING AN
INCREASE IN PCPN THIS AFTN WITH THE APPROACH AND PASSAGE OF A COLD
FRONT. STRONG OFFSHORE WINDS PROGGED TO DEVELOP IN THE WAKE OF THE
FRONT AND HAVE ISSUED CAUTION FLAGS AS A PRECURSOR. ADVISORY FLAGS
COULD REPLACE THE CAUTION ONES FOR THIS EVENING. THE ELEVATED SEAS
AND WINDS BEHIND THE FRONT WILL LIKELY BE SHORT LIVED AS HIGH PRES-
SURE BUILDS IN QUICKLY OVERNIGHT TONIGHT. A LIGHT NE/ELY FLOW WILL
BE IN PLACE FOR SUN/MON BEFORE THE HIGH MOVES FURTHER TO THE NE OF
THE AREA. ONSHORE WINDS SHOULD RETURN TO OUR COASTAL WATERS BY TUE
AS THE NEXT STORM SYSTEM MOVES OFF THE SRN ROCKIES INTO NORTH TX.
LONG-RANGE MODELS ARE STILL A BIT OFF WITH THE TIMING/STRENGTH OF
THE NEXT COLD FRONT...BUT SEEM TO BE FOCUSING ON NEXT THUR AS THE
PROBABLE DATE WITH THESE RUNS. 41

AVIATION...
NOT A LOT OF ISSUES WITH THE TAFS FOR THIS MORNING WITH THE COOL/DRY
REMAINING IN PLACE. WE ARE STILL EXPECTING SCT SHRA/VERY ISO TSRA AS
THE NEXT COLD FRONT MOVES IN FROM THE NORTH THIS AFTN. MAY ONLY MAKE
MINOR TWEAKS WITH THE TIMING OF FROPA WITH THE 12Z PACKAGE OTHERWISE
THE REST OF IT LOOKS GOOD. 41
