AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
1039 AM CST MON MAR 3 2008

.DISCUSSION...
COLD FRONT EXTENDS FROM TRINITY TO WILLIS TO SEALY. THE FRONT HAS
SLOWED A BIT...BUT SHOULD STILL CROSS THE HOUSTON AREA IN THE NEXT
1-2 HOURS AND PUSH OFF THE COAST 19-20Z. COORDINATED WITH SPC AND
CANCELLED THE SEVERE THUNDERSTORM WATCH FOR THE NW HALF OF THE CWA
WHERE FRONT HAS CLEARED. THERE IS SOME CONCERN ABOUT ISOLATED HAIL
PRODUCING STORMS BEHIND THE FRONT...BUT THE OVERALL THREAT IS LOW.
CONVECTION ALONG THE FRONT FROM HUNTSVILLE TO WESTERN HARRIS
COUNTY APPEARS TO BE GETTING BETTER ORGANIZED...AND WILL SEE
POTENTIAL FOR SEVERE WEATHER FOR THE NEXT COUPLE OF HOURS AS THIS
LINE OF STORMS MOVES INTO THE EASTERN ZONES. GIVEN THE HIGH PWS IN
PLACE (1.3-1.4 INCHES)...RAINFALL WILL BE WIDESPREAD AND HAVE KEPT
POPS 70-80 PCT. SEEING A QUICK 20 DEGREE DROP IN TEMPERATURES AS
THE FRONT PASSES AND HAVE MADE ADJUSTMENTS TO TEMPS/DEWPOINTS.
GUSTY NORTHWEST WINDS OCCURRING IN THE WAKE OF THE FRONT. HAVE
GONE AHEAD AND POSTED A WIND ADVISORY FOR THE FAR WESTERN COUNTIES
FROM 19Z-01Z WHERE SUSTAINED WINDS AROUND 25 MPH ARE EXPECTED.
WILL LIKELY NEED A WIND ADVISORY FOR THE COASTAL ZONES SECOND
PERIOD...BUT WILL ASSESS THIS IN THE AFTERNOON PACKAGE.

FOR MARINE...DROPPED GALE WATCH. SUSTAINED WINDS SHOULD REMAIN IN
SCA CRITERIA THOUGH GUSTS TO GALE FORCE ARE EXPECTED.

.PREV DISCUSSION... /ISSUED 703 AM CST MON MAR 3 2008/

DISCUSSION...
SEVERE THUNDERSTORM WATCH 90 IS NOW IN EFFECT FOR MUCH OF SOUTHEAST
TEXAS UNTIL 1 PM. LINE OF SHOWERS AND THUNDERSTORMS ALONG THE STRONG
COLD ABOUT TO ENTER OUR NORTHERN COUNTIES HAS THE POTENTIAL TO BECOME
SEVERE. 12Z SOUNDINGS SHOW A VERY STRONG CAP AT CRP AND VERY LITTLE
CAP AT LCH. STILL THINK OUR GREATEST RISK FOR SEEING ANYTHING SEVERE
WILL GENERALLY BE ALONG AND NORTH OF INTERSTATE 10. HAVE SENT OUT A
FORECAST UPDATE FOR THE WATCH...AND ALSO DID SOME FIRST PERIOD DOWNWARD
TEMPERATURE ADJUSTMENTS BASED ON THE COLDER AIRMASS ABOUT TO MOVE
INTO OUR AREA.  42

PREV DISCUSSION... /ISSUED 615 AM CST MON MAR 3 2008/

AVIATION...
SECTIONS OF THE LONG LINE OF THUNDERSTORMS DRAPED ACROSS CENTRAL
TEXAS DISPLAYING BOWING CHARACTERISTICS...60 MPH WINDS BEING
REPORTED AROUND KACT AT 11Z. -SHRA/ISO TSRA AHEAD OF THIS LINE TO
REACH THE NORTHERN-MOST HUBS AROUND 13Z...MAIN LINE TO COME ACROSS
IN THE 15-18Z TIME FRAME. MORE SOUTHERN HUBS WILL GET INTO THE
ACTION LATER THIS MORNING...SEVERITY OF STORMS THE MAIN QUESTION DUE
TO A CAP CREATED BY WARMER MID-LEVELS. FORCING RIGHT ALONG THE COLD
FRONT WILL INTRODUCE 19-21Z HOUSTON METRO THUNDERSTORMS. HAVE OPTED
TO KEEP A NON-CONVECTIVE WIND SHEAR GROUP IN CURRENT PREVAILING
ACROSS MANY TERMINALS TO ACCOUNT FOR LOW LEVEL NEAR-50 KNOT JET
AHEAD OF UPPER TROF. 3-4K FT VAD KHGX WINDS AOA 50 KNOTS GOING INTO
THE 12Z HOUR. WINDS BEHIND FROPA WILL BE ROBUST (ESPECIALLY THROUGH
COASTAL COUNTIES)...NW 15-25 KT RANGE WITH HIGHER GUSTS THROUGH THE
MIDNIGHT HOUR. 31

DISCUSSION...
A VERY MOIST AND CURRENTLY CAPPED AIRMASS IS IN PLACE ACROSS ALL OF
SOUTHEAST TEXAS EARLY THIS MORNING. SOME SHOWERS HAVE BEGUN TO DEVELOP
FROM AROUND MATAGORDA BAY TO CONROE AS THE LOW LEVEL JET CONTINUES TO
STRENGTHEN. AS THE DEEPENING NEW MEXICO UPPER LOW BEGINS TO MOVE EASTWARD
OVER THE NEXT SEVERAL HOURS...OUR AREA SHOULD BECOMING INCREASINGLY
UNSTABLE AS THE STRONG COLD FRONT THAT IS NOW APPROACHING A DALLAS TO
CLIFTON TO CHEROKEE LINE RACES TOWARD OUR CWA. THE MAIN SEVERE WEATHER
THREAT WILL CONTINUE TO BE DAMAGING STRAIGHT-LINE WINDS AND LARGE HAIL
ALONG THE COLD FRONT STORMS AND ISOLATED TORNADOES IN ANY OF THE STORMS
THAT MANAGE TO DEVELOP AHEAD OF THE COLD FRONT. IT STILL APPEARS THAT
THE GREATEST THREAT IS FOR AREAS GENERALLY ALONG AND NORTH OF INTERSTATE
10 DURING THE MORNING AND EARLY AFTERNOON HOURS. THE SEVERE THREAT IS
EXPECTED TO MOVE EAST OF OUR AREA DURING THE EARLY AFTERNOON HOURS AS
THE COLD FRONT HEADS TOWARD LOUISIANA. WILL CONTINUE TO CARRY EARLY
EVENING LOW RAIN CHANCES ACROSS SOME OF OUR NORTHEAST AND EAST COUNTIES.
IT REMAINS BREEZY EARLY THIS MORNING WITH SOUTH WINDS GENERALLY RUNNING
15 TO 20 MPH WITH HIGHER GUSTS. WILL CONTINUE TO CLOSELY MONITOR THE
WIND FIELDS EARLY THIS MORNING FOR A POSSIBLE WIND ADVISORY. TEMPERATURES
HAVE BEEN FALLING SOME 15 TO 20 DEGREES WITHING AN HOUR OR TWO BEHIND
THE CENTRAL TEXAS COLD FRONT...AND EXPECT SIMILAR TEMPERATURE PLUNGES
IN OUR AREA TODAY AS THE STRONG FRONT MOVES ON THROUGH. WE WILL LIKELY
NEED WIND ADVISORIES BEHIND THE FRONT...BUT WILL WAIT ON ISSUING THIS
PRODUCT UNTIL THE TIMING BECOMES A LITTLE MORE CERTAIN.

THE AREA WILL SEE DRY AND COOL WEATHER ON TUESDAY UNDER THE CONTROL
OF SURFACE HIGH PRESSURE. THE HIGH MOVES EAST ON TUESDAY NIGHT AND
WEDNESDAY RESULTING IN A WARMING TREND. THE NEXT COLD FRONT ARRIVES
ON THURSDAY AND WILL CARRY A CHANCE OF SHOWERS FOR THE AREA. DRY AND
COOLER AIR SPILLS INTO SOUTHEAST TEXAS FOR THE END OF THE WEEK AS
SURFACE HIGH PRESSURE ORIGINATING IN NORTHWEST CANADA BUILDS ON IN.
A WARMUP WILL BEGIN ON SATURDAY WITH THE RETURN OF ONSHORE WINDS.
WILL MAINTAIN A DRY FORECAST FOR THE WEEKEND.  42

MARINE...
ALL MARINERS AND THOSE WITH BOATING INTERESTS BE AWARE OF VERY
STRONG WINDS...SOUTHERLY AHEAD OF THIS AFTERNOONS COLD FRONTAL
PASSAGE ACROSS ALL LOCAL WATERS AND NORTHERLY BEHIND THE FRONTAL
PASSAGE...WITH HIGH SEAS THROUGH TUESDAY MORNING. ROUGH BOATING
CONDITIONS ARE ALL HIGHLIGHTED IN THIS MORNINGS MARINE WEATHER
WARNING (SATMWWHGX). LOCAL BAY AND NEARSHORE SCEC THROUGH NOON...SCA
FOR OFFSHORE WATERS. A GALE WATCH WITH A COMBINED SCA FOR ALL WATERS
FROM NOON ONWARD THROUGH TUESDAYS SUNRISE. COLD FRONT CURRENT
MAKING ITS WAY ACROSS CENTRAL TEXAS AT THIS WRITING...IS TIMED TO
MAKE THE COAST AROUND 4 PM THIS AFTERNOON. NOW IS THE TIME TO MAKE
THE PROPER PREPARATIONS TO EITHER SEEK SAFE HARBOR...OR MAKE
ALTERNATE ROUTING PLANS.
