.AVIATION...
SLIGHT UPPER LEVEL RIDGING WAS OCCURRING OVER SE TX LATE THIS
EVENING. THERE WAS SOME SLIGHT ENOUGH SUBSIDENCE TO KEEP THE RAIN
AREA IN FAR SOUTH TEXAS FROM EXTENDING UP THE COAST TO THE RAIN
BAND THAT WAS DISSIPATING OVER THE LOWER SABINE RIVER VALLEY. THE
00Z RUN OF THE HIGH RESOLUTION ARW AND NMM BOTH WERE REFLECTING
THIS...ALTHOUGH BOTH REDEVELOP A RAIN BAND OVER THE KCLL AND KUTS
AREAS AFTER 09Z. THE 00Z 4KM WRF FROM NCEP ALSO WAS FORECASTING
THIS SAME SCENARIO ALTHOUGH THE RAIN BAND APPEARED TO BE A BIT
FURTHER TO THE WEST. CONVECTION TO THE SOUTHEAST OF THESE TWO
SITES LOOKED TO BE MORE LIMITED. THE 00Z GFS MODEL RUN SHOWED MORE
STRETCHING OF THE VORTICITY FIELD AS WELL AND INDICATED THAT RAIN
CHANCES WILL BE LESS DURING THE AFTERNOON OVER THE HOUSTON METRO
AND COASTAL SITES.

UPDATE...
SEE EVENING UPDATE.
DISCUSSION...
RADAR IS A BIT MORE QUIET THAN THE PAST COUPLE OF NIGHTS. SHORT
TERM GUIDANCE AND GLOBAL MODELS CONTINUE TO SUGGEST ADDITIONAL
SHRA/TSRA DEVELOPING AFTER MIDNIGHT OVER THE NW ZONES. THIS SEEMS
REASONABLE AS 00Z SOUNDINGS SHOW PW VALUES BETWEEN 2.20-2.40
INCHES. AN 850 MB TROUGH IS DRAPED ACROSS EAST AND CENTRAL TEXAS.
WATER VAPOR IMAGERY SHOWS A WEAK DISTURBANCE HEADING TOWARD SOUTH
TEXAS AND THIS FEATURE WILL HELP TO SERVE AS A TRIGGER FOR
CONVECTION LATER. HAVE EXTENDED THE FLASH FLOOD WATCH THROUGH 10Z
FOR THE ENTIRE CWA. A WATCH MEANS THERE IS POTENTIAL FOR FLASH
FLOODING. RAINFALL AMOUNTS HAVE BEEN TAME OVER HOUSTON BUT HEAVY
RAIN TO THE WEST AND EAST OF THE CITY HAS PRODUCED SIGNIFICANT
FLOODING ISSUES AND RIVERS REMAIN VERY HIGH. THOUGHT THE SHORT
TERM MODELS INITIALIZED WELL AND HAVE LEANED TOWARD A BLEND OF THE
HI-RES ARW...RAP AND HRRR. 43
CLIMATE...
CRUNCHED A FEW RAINFALL NUMBERS AND SINCE JAN 1ST...BRENHAM HAS
RECEIVED 45.77 INCHES OF RAIN WHICH IS MORE THAN THE 30 YEAR
NORMAL RAINFALL FOR THE ENTIRE YEAR (45.14 INCHES). BAYTOWN IS
THE FIRST SITE IN THE CWA TO RECORD OVER 50 INCHES OF RAIN FOR THE
YEAR (54.15). THIS IS ABOUT 90 PERCENT OF THE 30 YEAR ANNUAL
NORMAL(59.92). WILL BE SENDING A GRAPHIC OUT ON TWITTER/FACEBOOK
WITH OTHER RAINFALL TOTALS ACROSS THE CWA. 43

A FEEDER BAND ALONG THE COASTAL COUNTIES WAS AFFECTING KIAH...
KHOU...AND KGLS AT 23Z. EXPECT THAT AT LEAST VCSH WILL BE POSSIBLE
THROUGH 03Z. MAY NEED TO UPDATE LATER IF THIS BAND PERSISTS.
HOWEVER...SHORT RANGE HIGH RESOLUTION MODELS FORECAST THE BAND TO
DISSIPATE WITH ANOTHER BECOMING MORE PROMINENT OVER AT LEAST
KCLL...KUTS...AND KCXO LATER TONIGHT. MORE ISOLATED TO SCATTERED
ACTIVITY POSSIBLE MAINLY AFTER 18Z THURSDAY. OTHERWISE...CEILINGS
SHOULD BE VFR OUTSIDE OF THE RAIN AREAS.

DISCUSSION...
EXTENDING THE FLOOD WATCH TO 11 PM.
VERY MOIST AIRMASS STILL IN PLACE AND FEEDING INTO THE AREA FROM
THE GULF THANKS TO TD BILL. STORMS THAT HAVE BEEN IN PLACE NEAR
CRP AND THE GULF WATERS TO A COMBINATION OF S/W OVER MEXICO AND
THE CONVERGENCE ON THE FAR SOUTH FLANK OF BILL MERGING INTO THE
TROPICAL MOISTURE WHICH ARCS AROUND INTO CHAMBERS COUNTY AND UP
INTO NEWTON/JASPER COUNTIES. THE MOISTURE STILL FLOWING BACK INTO
SETX AND WITH THE INCOMING MEXICO S/W THINK THAT IT IS A GOOD IDEA
TO EXTEND THE FLASH FLOOD WATCH TO 11 PM. RAINS THOUGH INTENSE AT
TIMES SHOULD BE MORE OF A WIDE SCATTERED TO ISOLATED NATURE
TONIGHT...FIRST ACROSS THE SOUTH AND EAST LATE AFTERNOON AND
EVENING SWITCHING TO THE NORTHERN AREAS OVERNIGHT. INSTABILITY
DEVELOPING NEAR AUSTIN SPREADING EASTWARD WITH AFTERNOON HIGHS OF
90+ AND 72-75 DEWPOINTS SHOULD SPREAD INTO THE NORTHERN AREAS THIS
EVENING AND BE FUEL FOR STORMS MAYBE EVEN SOME STRONG STORMS.
RAINFALL TOTALS WILL LIKELY HAVE A VERY BROAD RANGE...MANY SITES
LESS THAN 0.25" BUT SOME ISOLATED AREAS OF 2 TO 5 INCHES POSSIBLE
FROM THIS AFTERNOON THROUGH LATE EVENING. YESTERDAYS SOAKING
COMBINED WITH TODAYS RAINS HAS DONE A GREAT JOB OF SATURATING THE
SOIL SO RUNOFF WILL BE EASY AND PLENTIFUL IF HEAVY RAINS DEVELOP.
THE BEST CONVERGENCE REMAINS OVER THE NORTH THURSDAY AND SO WILL
KEEP POPS HIGHER NORTH AND LOWER ACROSS THE SOUTH WITH THE
CONTINUED THREAT OF HEAVY RAIN BUT AGAIN MORE ISOLATED IN NATURE.
RAIN CHANCES DO DECREASE GOING THROUGH THE WEEKEND AS RIDGING
BUILDS IN FROM THE EAST AND SHEAR AXIS RETREATS INTO THE HILL
COUNTRY BY SUNDAY NIGHT. THIS SHOULD LIMIT RAIN AND LEAD TO
TEMPERATURES BACK INTO THE 90S. GREATER RAIN CHANCES WILL LIKELY
RETURN TO THE REGION AS MOISTURE POOLED OVER THE GULF FINALLY
MOVES INTO TEXAS LATE WEDNESDAY THROUGH FRIDAY AS UPPER RIDGE
OVER THE GULF RETREATS EASTWARD.
RIVERS...
MANY OF THE RIVERS IN THE SOUTHWESTERN PORTIONS OF SOUTHEAST TEXAS
ARE FORECAST TO RISE TO MODERATE FLOOD LEVELS AND SOME TO MAJOR
AND EVEN THREATENING RECORD LEVELS. THE FLOODING ON THE MUSTANG
BASIN IS NEARING HISTORIC LEVELS WITH HIGHWAY 59 CLOSED AND
REROUTED AS WELL AS MANY HOUSES CUT OFF.
45
MARINE...
TROPICAL DEPRESSION BILL CONTINUES TO LIFT AWAY WITH BANDS OF
SHOWERS REMAINING BEHIND. TAF SITES RELATIVELY QUIET IN BETWEEN RAIN
AREAS TO THE EAST AND WEST. AS BILL LIFTS NORTH AND RIDGE OF HIGH
PRESSURE BUILDS IN FROM THE EAST...WILL SEE PRESSURE GRADIENT OVER
THE MARINE AREA SLACKEN SOME ALLOWING FOR WINDS...SEAS AND STORM
TIDES TO ONLY GRADUALLY DECREASE. HOWEVER WILL STILL MAINTAIN
PERSISTENT ONSHORE FLOW ON WESTERN FLANK OF THE HIGH...GENERALLY 10
TO 15 KNOTS...THROUGH THE FORECAST PERIOD. SEAS CURRENTLY RUNNING 5
TO 6 FEET AT BUOYS 19 AND 35. SHOULD DROP A FOOT OR SO BY TOMORROW
AND ANOTHER FOOT BY THE WEEKEND.
