AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
635 AM CST THU DEC 8 2005

.AVIATION...
LOW CLOUDS ABOUND...LOWER CIELINGS FROM BYY THROUGH IAH/HOU TO JAS
AT 700-1100 FEET. SHALLOW COLD AIRMASS KNIFEING IN BENEATH THE
WARMER ATMOSPHERE PRODUCING THE DRASTIC INVERSION. CIELINGS
IMPROVING AS DISTANCE INCREASES TO THE NORTHWEST BUT STILL ONLY
1300-2000 FEET AS FAR NORTHWEST AS ACT-CRS. CLEARING LINE SJT-MWL-
DUA SPREADING SOUTHEAST AT ONLY 10-12 KNOTS. SURFACE TEMEPRATURES IN
THE MID-UPPER 20S NORTHWEST TO 32-41 SOUTH. ACARS 0919Z SOUNDING
INDICATING LARGE SATURATED WARM NOSE ALOFT TO 9C AROUND 3000 FEET.
PROFILERS SHOW ONLY 15 TO 25 KNOTS IN THE COLD AIRMASS AND LIGHTER
SW FLOW ABOVE THROUGH 700MB. HAVE SLOWED THE CIELING IMPROVEMENTS
FROM PREVIOUS TAFS...AT IAH 11-1800 FEET CIGS SHOULD PREVAIL THROUGH
21Z...LBX TIL 00Z. RAPID IMPROVEMENT AFTERWARDS..VFR. 45

&&

.MARINE...
SCA ALL WATERS. COLD AIR SPILLING OUT OVER THE WARM GULF WINDS
CURRENTLY RUNNING 18-25G24-33KT THIS SHOULD CONTINUE THROUGHOUT THE
DAY. WIND PROFILERS INLAND ONLY SHOWING WINDS OF 15 TO 20 KNOTS IN
THE COLD AIRMASS. HAVE TRENDED DOWN THE WINDS A SCOSH AND LOWERED
PEAK WIND GUSTS TO AROUND 35 KNOTS. THESE STRONG WINDS SHOULD
CONTINUE THROUGH FRIDAY OFFSHORE...TONIGHT NEARSHORE. ANOTHER COLD
FRONT SATURDAY NIGHT/SUNDAY MORNING BUT MUCH WEAKER. THOUGH WELL
BEYOND THE PERIOD OF THIS FORECAST...VERY IMPRESSIVE RIDGE ALONG THE
WEST COAST INTO THE ARCTIC...LOOKS LIKE BARBED WIRE MAY BE ALL THAT
STANDS BETWEEN US AND SOME COLD AIR AFTER THE 18TH. 45

&&
.PREVIOUS DISCUSSION...
THE WINTER WEATHER EVENT WAS WRAPPING UP ACROSS THE NORTHERN AND
WESTERN PORTIONS OF SE TX THIS HOUR. IMMEDIATE WEATHER PROBLEMS OF
THE DAY INCLUDE CHANCES FOR MORE PRECIP...TEMPERATURES...AND WIND.
TEMPERATURES ARE THEN A MAJOR CONCERN FOR TONIGHT AND FRIDAY
MORNING.

THIS MORNING...A MID TO UPPER AREA OF LOW PRESSURE WAS OVER THE
PLAINS WITH AN ACTIVE SUBTROPICAL JET ACROSS THE TX COASTAL PLAIN
AND WESTERN GULF. A COLD FRONT WAS NOW OFF THE COAST AND FREEZING
TEMPERATURES AT 09Z WERE BASICALLY ALONG AND WEST OF A LINE FROM
CROCKETT TO SUGARLAND TO EDNA. THE MAIN AREA OF PRECIPITATION HAS
PUSHED NORTHEAST OUT OF THE FORECAST AREA...HOWEVER...POCKETS OF
LIGHT RAIN WERE DEVELOPING ACROSS FORT BEND...HARRIS...AND LIBERTY
COUNTIES.

FOR THE SHORT TERM...A COLD DAY IS IN STORE. AM NOT EXPECTING ANY
MORE FREEZING RAIN ALTHOUGH SOME PATCHY FREEZING DRIZZLE IS NOT
OUT OF THE QUESTION BEFORE SUNRISE. HOWEVER...THE MAIN ISENTROPIC
LIFT (AS SEEN ON THE ETA 300K SURFACE) HAS PUSHED EASTWARD. THINK
THAT THE DIURNAL TEMPERATURE CHANGE WILL BE VERY SMALL TODAY WITH
SOME AREAS MAYBE SEEING FALLING OR NEAR STEADY TEMPERATURES. WINDS
ALOFT IN THE FIRST FEW THOUSAND FEET DO NOT IMPLY WIND ADVISORY
CRITERIA TODAY BUT WIND SPEEDS SHOULD BE 15 TO 20 MPH.

TONIGHT THE ETA12 IS LOOKING LIKE A GOOD MODEL FOR TEMPERATURES.
OVERNIGHT LOWS SHOULD GET TO NEAR 20 OVER THE NORTHERN COUNTIES...
THE MID 20S CENTRAL...AND MID 30S AT THE COAST. WILL CONSIDER
FREEZE WARNINGS FOR THOSE LOCATIONS THAT HAVE NOT HAD THE FIRST
FREEZE OF THE SEASON LATER TODAY.

THE GFS IMPLIES THE FAST MOVING FLOW TO CONTINUE WITH A SEMI-
ACTIVE SUBTROPICAL JET REMAINING NEAR OR OVER SE TX. THERE STILL
LOOKS TO BE A SLIGHT CHANCE OF RAIN NEAR THE COAST FRIDAY AND
FRIDAY NIGHT WITH THE NEXT CHANCE OF RAIN LATE TUESDAY INTO
WEDNESDAY. IN THE LONG TERM...THE GFS IS IMPLYING A TURN TO COLDER
WEATHER OVER THE SOUTHERN PLAINS WITH A RIDGE BUILDING UP THE WEST
COAST INTO ALASKA.
