AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
1109 AM CST SAT JAN 8 2011

.AVIATION...
NE TO E FLOW ATTM WITH WINDS PRIMARILY 5-15 KNOTS...NEAR THE HIGH
END ON THE COAST. S TX CLOUD DECK EXPANDING NORTHWARD AND WILL
CONTINUE TO DO SO THIS AFTERNOON AND EXPECT MID/HIGH CLOUDS REACHING
TERMINALS BEFORE 01Z. STEADILY LOWERING CIGS WITH MVFR LIKELY BE
09Z. VERY WET WEATHER WILL BE ON TAP AFTER 09Z PEAKING AS THE STORM
SYSTEM PASSES OVER THE AREA TERMINALS. LLWS ISSUES WILL LIKELY
ABOUND WITH EASTERLY SURFACE WINDS AND SSE-SE WINDS ALOFT OF 35-50
KNOTS. INSTABILITY IS SLIM AT BEST AND SO EXPECT PRIMARILY RAIN WITH
A LARGE SHIELD OF +RA AND IFR CIGS TO DEVELOP AROUND 12Z CLL AND
EXPAND EAST INTO CXO/IAH/HOU/SGR BY 14-16Z. IMPROVEMENT AFTER 19Z
FOR IAH/HOU.
45

&&
.MARINE...
WINDS COMING UP QUICKLY SO HAVE EXPANDED THE DURATION OF THE SCA AND
HAVE ISSUED A GALE WARNING FOR THE COASTAL WATERS TONIGHT. CURRENT
SUITE OF MODELS DEPICTING A VERY STRONG WAA PATTERN AS LOW MOVES OFF
COASTAL BEND. SUSTAINED WINDS OF 25-30 KNOTS WILL BE COMMON OVER THE
GULF WATERS WILL FREQUENT GUSTS OF 35 KNOTS AND GIVEN THE PROFILE
SOME GUSTS AS HIGH 45 KNOTS COULD OCCUR OVER THE 20-60NM WATERS.
ADDITIONALLY THE POSSIBILITY OF STRONG TO SEVERE THUNDERSTORMS WILL
EXIST MAINLY OVER THE WATERS BEYOND 20NM...ABUNDANT HELICITY BUT
HAMPERED BY SLIM SLICE OF INSTABILITY.

TIDES: THOUGH TIDE LEVELS ARE AT NORMAL NOW THE INCREASED WINDS AND
ATTENDANT TIDES WILL RISE TO NEAR 3 FEET AND COULD EASILY RAMP UP TO
4 FEET MAINLY FOR AREAS FROM FREEPORT TO HIGH ISLAND. WILL LIKELY BE
ISSUING A COASTAL FLOOD ADVISORY SHORTLY.

.PREV DISCUSSION... /ISSUED 952 AM CST SAT JAN 8 2011/

DISCUSSION...
12Z SOUNDINGS SHOW MAX TEMPS IN THE UPPER 60S TODAY BUT COLD AIR
FILTERING IN FROM THE NORTH AND CLOUD COVER ENCROACHING FROM THE
SOUTH WILL LIKELY MAKE UPPER 60S UNREACHABLE. CURRENT TEMP FCST
LOOKS TO BE ON TARGET. WINDS ARE ALREADY INCREASING AND BUOY035 IS
AT 16 KTS. HAVE ISSUED AN SCEC FOR THIS AFTERNOON AND BUMPED WINDS
UP ALONG THE COAST. TIDES WILL LIKELY BE A BIT HIGHER THAN
PREVIOUSLY THOUGHT AS EAST WINDS INCREASE TO ALMOST 30 KNOTS
OVERNIGHT. WILL BE ISSUING A COASTAL FLOOD ADVISORY WITH THE
AFTERNOON PACKAGE. A WIND ADVISORY WILL ALSO BE ISSUED FOR LATE
TONIGHT/SUNDAY FOR AREAS EAST OF US HIGHWAY 59 FOR SUSTAINED
WINDS OF 25 MPH. AS FOR WINTER WEATHER...NO CHANGES AT THIS TIME
BUT THE NAM 12 DOES SUPPORT SOME TYPE OF WINTRY PRECIP. SOUNDINGS
ARE SATURATED FROM 800 MB TO THE SFC BUT STRADDLES THE ZERO
ISOTHERM FROM THE TOP OF THE SATURATED LAYER TO 950 MB. NOT SURE
IF THIS IS COLD ENOUGH TO PRODUCE SNOW OR JUST A COLD RAIN. WILL
WAIT FOR OTHER MODEL SOLUTIONS BEFORE MAKING OTHER CHANGES. 43

PREV DISCUSSION... /ISSUED 453 AM CST SAT JAN 8 2011/

DISCUSSION...
A COLD FRONT IS PUSHING SOUTH THROUGH THE CWA EARLY THIS MORNING
JUST NOW REACHING THE COASTAL ZONES. THE OB AT KHOU SHOWED THE SFC
DEWPOINT DROPPING FROM 45 TO 35 IN THE LAST HOUR WITH AN INCREASE
IN WIND TO 13 KTS. ANOTHER NICE DAY IS IN STORE FOR TODAY EXCEPT
THAT TEMPS WILL BE 5-10 DEGREES COOLER THAN YESTERDAY IN THE WAKE
THE FRONT. EXPECT MOSTLY SUNNY SKIES THIS MORNING...WITH MID
LEVEL CLOUDS SPREADING WEST TO EAST ACROSS THE AREA THIS AFTN.

POTENT UPPER LEVEL LOW NOW OVER SOUTHERN ARIZONA WILL MOVE EAST
ACROSS TEXAS TONIGHT AND SUNDAY BRINGING A VARIETY OF IMPACTS TO
THE AREA. A 40-50 KT LOW LEVEL JET WILL DEVELOP TONIGHT RESULTING
IN A RAPID INCREASE IN MOISTURE TO THE AREA. PWS ARE FORECAST TO
REACH 1.1-1.5 INCHES OVER THE SRN HALF OF THE AREA SUNDAY MORNING.
FLOW ALOFT BECOMES STRONGLY DIFFLUENT LATE TONIGHT AND SUNDAY
MORNING. A SFC BOUNDARY WILL SET UP ALONG THE COAST WITH AN 850 MB
BOUNDARY SETTING UP OVER THE NRN PORTION OF THE CWA. BEST LOW LEVEL
CONVERGENCE WILL BE FOCUSED ALONG THESE TWO BOUNDARIES. LOCALLY
HEAVY RAINFALL IS LIKELY ESPECIALLY ACROSS THE SRN HALF THE AREA
LATE TONIGHT/SUNDAY MORNING. WIDESPREAD RAINFALL AMOUNTS OF 1-2
INCHES ARE EXPECTED WITH ISOLATED TOTALS OF 2-4 INCHES ESPECIALLY
OVER THE SRN HALF OF THE CWA. WILL MENTION LOCALLY HEAVY RAINFALL IN
GRIDS AND HWO WITH POTENTIAL FOR MINOR FLOODING. TREMENDOUS AMOUNTS
OF LOW LEVEL SHEAR ARE FORECAST BY THE MODELS (HELICITIES > 800
M2/S2). MODELS CONTINUE TO SUGGEST THE POSSIBILITY OF THE WARM FRONT
SURGING INLAND OVER THE COASTAL ZONES FOR A FEW HOURS FROM AROUND
10-16Z SUNDAY. SPC DAY 2 OUTLOOK HAS A SEE TEXT FOR THE COASTAL
ZONES. THE DYNAMICS FAVOR THE DEVELOPMENT OF A SQUALL LINE WHICH
WILL AFFECT THE COASTAL AND MARINE ZONES DURING THE MORNING HOURS
SUNDAY WITH STRONG WINDS AND WATERSPOUTS BEING THE PRIMARY THREAT.
WILL MENTION SEVERE THREAT IN THE HWO BUT NOT THE GRIDS. ELEVATED
INSTABILITY WILL FAVOR ISOLATED THUNDER FOR INLAND AREAS AS WELL.
THE HEAVY RAIN AND STORMS ARE EXPECTED TO END BY EARLY AFTN WITH
WRAP AROUND PRECIP LINGERING OVER NRN ZONES INTO THE AFTERNOON.

IN ADDITION TO THE HEAVY RAIN AND SEVERE POTENTIAL...STRONG WINDS
ARE LIKELY TO IMPACT THE COASTAL AND MARINE AREAS...WITH ELEVATED
TIDES AS WELL. SEE MARINE DISCUSSION BELOW FOR MORE DETAILS. A
WIND ADVISORY MAY BE NEEDED LATE TONIGHT/EARLY SUNDAY FOR COASTAL
AREAS.

WINTER WEATHER IS ANOTHER THREAT AS WELL OVER OUR NE ZONES. THE
GFS BUFR SOUNDING AT KLFK INDICATES PRECIP STARTING OFF AS A
SNOW/SLEET MIX LATE TONIGHT...THEN CHANGING TO RAIN FOR A FEW
HOURS IN THE MORNING BEFORE SWITCHING BACK TO A WINTER MIX IN THE
AFTN. 00Z NAM SHOWED A MOSTLY RAIN EVENT WHILE THE ECMWF WAS A
GOOD COMPROMISE BETWEEN THE GFS/NAM. THE MAIN AREA OF CONCERN IS
HOUSTON...MADISON...TRINITY...AND NORTHERN POLK COUNTIES. WILL
FORECAST A MIX OF RAIN...SLEET AND SNOW DURING THE DAY SUNDAY IN
THIS AREA...WITH SOUNDINGS SUPPORTING VERY LIGHT FREEZING
RAIN/FREEZING DRIZZLE OR SNOW FLURRIES SUNDAY EVENING. IF THE
CHANGEOVER OCCURS IN THE MORNING...THE POTENTIAL EXISTS FOR HEAVY
SLEET OR WET SNOW TO FALL IN THIS AREA WITH SIGNIFICANT ACCUMULATIONS.
HAVE HELD OFF ON A WATCH FOR NOW BUT MAY NEED ONE IN A LATER
FORECAST PACKAGE. FURTHER SOUTH AND WEST...THERE IS THE POTENTIAL
FOR SNOW FLURRIES OR VERY LIGHT FREEZING RAIN TO IMPACT AREAS AS
FAR SOUTH AND WEST AS COLLEGE STATION...HUNTSVILLE...AND
LIVINGSTON SUNDAY EVENING. HOWEVER...PRECIP AT THIS POINT WOULD BE
VERY LIGHT WITH ACCUMULATIONS EITHER NON-EXISTENT OR STAYING IN
THE ADVISORY RANGE.

THE WEATHER WILL TURN SHARPLY COLDER SUNDAY WITH THE ARRIVAL OF
THE STORM WITH MAX TEMPS OCCURRING EARLY IN THE DAY MOST AREAS.
COLDER WEATHER WILL PERSIST THROUGH THE MIDDLE OF NEXT WEEK. THE
SECONDARY MODIFIED ARCTIC COLD FRONT WILL PUSH THROUGH SE TX
TUESDAY MORNING. COLDER AIRMASS WILL SPREAD INTO THE AREA IN THE
WAKE OF THE FRONT WITH DEWPOINTS DROPPING TO THE TEENS/LOW 20S.
HAVE COMPROMISED BETWEEN COLDER ECMWF AND GFS FOR TEMPS. IF SKIES
CAN CLEAR ENOUGH THAN A HARD FREEZE WILL BE POSSIBLE OVER THE NRN
ZONES TUE NIGHT AND POSSIBLY AGAIN WED NIGHT. FURTHER SOUTH...ONLY
A LIGHT FREEZE IS EXPECTED AT THIS TIME. ISENTROPIC LIFT WILL
BEGIN WEDNESDAY AND PERSIST INTO THURSDAY...WITH MID LEVEL CLOUD
DECK FORMING. ALTHOUGH SOUNDINGS WOULD SUPPORT SLEET AND POSSIBLY
SNOW THIS PERIOD...HAVE LEFT PRECIP OUT OF THE FORECAST AS LOW
LEVELS ARE VERY DRY. MAX TEMPS WEDNESDAY WILL LIKELY STAY IN THE
30S WITH THE CLOUD COVER. WARM ADVECTION WILL BEGIN IN EARNEST THU
NIGHT AS SFC HIGH MOVES EAST AND ANOTHER SHORTWAVE APPROACHES
FROM THE WEST. EXPECT SHOWERS ON FRIDAY FOLLOWED BY MUCH WARMER
TEMPS FOR NEXT WEEKEND.
