What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Houston/Galveston, TX wrote its last area forecast discussion before this river flood warning went out at Feb 18, 5:31 PM CST, 28 minutes earlier.

Area forecast discussion, Feb 18, 5:31 PM CST, 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
531 PM CST SAT FEB 18 2012

.AVIATION...
MOST TAF SITES WILL BE DEALING WITH WRAP AROUND LOW CLOUDS (POSSIBLY
IFR/LIFR) THROUGHOUT THE NIGHT...AND POSSIBLY AREAS OF LIGHT RAIN
AND FOG TOO AS THE STORM SYSTEM CONTINUES TO MOVE OFF TO THE EAST.
EXPECT TO SEE INCREASING WINDS THIS EVENING AND OVERNIGHT...ESPECIALLY
ALONG THE COAST. WITH THE SYSTEM MOVING OUT OF THE STATE TOMORROW...LOOKS
LIKE CLEARING SKIES IN THE MORNING WITH LIGHTER NORTH TO NORTHEAST WINDS
IN THE AFTERNOON.  42
&&

.PREV DISCUSSION... /ISSUED 336 PM CST SAT FEB 18 2012/

DISCUSSION...
UPPER LOW WILL CONTINUE MAKING ITS WAY TOWARD ARKANSAS/TENNESSEE
TONIGHT. CURRENTLY SEEING A SPOKE OF ITS ASSOCIATED PRECIPITATION
MOVE ACROSS NORTHERN PARTS OF THE AREA...AND WOULD ANTICIPATE SCT
ACTIVITY FOR AREAS GENERALLY N OF I-10 (ISO SOUTH) INTO THE
EVENING HOURS. COULD SEE A ELEVATED TSTM OR TWO ACROSS NRN AREAS
AS WELL. KNOW SEVERAL PEOPLE HAVE SATURATED GROUNDS UP THERE...BUT
NOT ANTICIPATING MUCH IN THE WAY OF FLOODING PRECIP. PROBABLY
AMOUNTS <1/4" AND 1/2" AT THE MOST. DRIER COOLER WX FILTERS IN
OVERNIGHT.

NOT MUCH CHANGE IN THE REST OF THE FCST. ONSHORE WINDS WILL RESUME
SUNDAY NIGHT AS SFC PRESSURES FALL IN ADVANCE OF THE NEXT TROF
SCHEDULED TO MOVE THRU THE PLAINS ON MONDAY. THIS SYSTEM WILL DRAG
A COOL FRONT INTO THE AREA MONDAY NIGHT...BUT WILL BECOME DIFFUSE
SOMEWHERE OVER SE TX OR JUST OFFSHORE AS THE BOUNDARY LOSES SWD
MOMENTUM AS IT BECOMES PARALLEL TO UPPER FLOW. MOISTURE WILL
PROBABLY BE LACKING FOR MUCH IN THE WAY OF RAINFALL - MAYBE JUST SOME
ISOLATED SHOWERS.

THINGS LOOK TO REALLY WARM UP INTO THE MIDWEEK TIME PERIOD AS SFC
WINDS BECOME SW/W AND DEWPOINTS FALL. NUDGED TEMPS UP A BIT BUT
HAVE A FEELING WE MAY NEED TO GO QUITE A BIT HIGHER (INTO THE 80S) IF
FCST TRENDS CONTINUE.

LOOKS LIKE ANOTHER MID LEVEL TROF WILL DIG DOWN INTO BAJA DURING
THE MIDWEEK TIME PERIOD AND EJECT OVER TX SOMETIME BETWEEN FRI-SUN
DEPENDING ON THE MODEL. OTHER THAN AGREEING THAT A COLD FRONT WILL
PUSH THRU EARLY FRI...NOT MUCH CONFIDENCE AS TO WHAT RAIN CHANCES
WILL LOOK LIKE AT THAT TIME. LEFT THEM LOW AND WILL ADJUST WITH
TIME.  47

MARINE...
THE PRESSURE GRADIENT BEHIND THE SURFACE LOW DEPARTING TO THE EAST
WILL BE STRONG ENOUGH TO GENERATE OFFSHORE WINDS WHICH WILL GUST
BETWEEN 20 AND 30 KNOTS THIS EVENING. THE 20 TO 60 NM OFFSHORE
WATERS WILL ALSO LIKELY EXPERIENCE GALE FORCE WIND GUSTS THROUGH
THIS EVENING. THE MODELS ARE THEN CONSISTENT IN DECREASING THE WINDS
TO UNDER ADVISORY LEVELS LATER ON SUNDAY. MODERATE ONSHORE WINDS
WILL RETURN FOR THE FIRST OF NEXT WEEK BEFORE A WEAK COLD FRONT
WORKS ITS WAY JUST OFF THE COAST LATE TUESDAY MORNING OR EARLY
AFTERNOON. AT THIS TIME...IT DOES NOT LOOK LIKE THIS FRONT WILL MAKE
ITS WAY TOO FAR OFF THE COAST BEFORE IT RETURNS NORTHWARD AS A WARM
FRONT TUESDAY EVENING.  40
