SHORT TERM (TODAY THROUGH THURSDAY)...COLD AIRMASS FIRMLY
ENTRENCHED ACROSS SOUTH TEXAS. STILL COLD AIR ADVECTION TAKING
PLACE ACROSS THE AREA...ESPECIALLY EASTERN CWA. WINDS HAVE FALLEN
OFF ACROSS THE BRUSH COUNTRY AND RIO GRANDE PLAINS...IN MANY AREAS
TO LESS THAN 10 MPH. THEREFORE CANCELLED THE WIND CHILL ADVISORY
FOR THIS REGION. HAVE MAINTAINED THE WIND CHILL ADVISORY THROUGH
9 AM FOR THE COASTAL BEND AND VICTORIA CROSSROADS. ONLY CHANGE TO
THE FREEZE WARNING WAS TO CANCEL ARANSAS COUNTY. MOST OF ARANSAS
COUNTY (ESPECIALLY POPULATED AREA) WILL REMAIN JUST ABOVE
FREEZING. OTHERWISE A COLD DAY ACROSS SOUTH TEXAS WITH WINDS
CONTINUING TO DIMINISH AND THIN CIRRUS STREAMING INTO THE AREA.
HIGHS ONLY IN THE UPPER 40S TO LOW 50S. TONIGHT...A WEAK COASTAL
TROUGH DEVELOPS ACROSS THE MIDDLE TEXAS COASTAL WATERS...DRIFTING
TOWARDS THE COAST THURSDAY MORNING. A LIGHT FREEZE IS POSSIBLE
AGAIN ACROSS INLAND COUNTIES. ISENTROPIC UPGLIDE INCREASE ACROSS
THE GULF OVERNIGHT AND RAPIDLY DEVELOPS ACROSS THE EASTERN CWA
DURING THE DAY THURSDAY. THIS WILL RESULT IN MOSTLY CLOUDY TO
OVERCAST CONDITIONS DEVELOPING ACROSS THE EASTERN CWA THURSDAY...
WITH THE POTENTIAL FOR SPRINKLES OR LIGHT RAIN. HIGHS IN THE UPPER
50S TO LOW 60S ACROSS THE EAST...WARMER OUT WEST IN THE MID 60S.

LONG TERM (THURSDAY NIGHT THROUGH TUESDAY)...ISENTROPIC UPGLIDE AND
BOUNDARY LYR CONVERGENCE FROM A COASTAL TROUGH/APPROACHING COLD
FRONT WL BE SUFFICIENT TO PRODUCE ISOLATED TO SCATTERED PCPN ACROSS
PRIMARILY THE COASTAL BEND AND WATERS THU NIGHT AND FRI.  PCPN IS
EXPECTED TO SHUT OFF BY FRI AFTN WITH THE NEXT COLD FRONT.  BELOW
NORMAL TEMPS ARE THEN EXPECTED THROUGH SAT NIGHT AS A SFC RDG AXIS
BUILDS IN FROM THE NORTH. ANOTHER LIGHT FREEZE IS LKLY ACROSS THE
NRN PORTIONS OF THE COASTAL BEND AND BRUSH COUNTRY SUNDAY MORNING.
A RAPID DEVELOPMENT OF A COASTAL TROUGH AND ASSCTD ISENTROPIC
UPGLIDE DURING THE DAY ON SUNDAY WL QUICKLY BRING BACK THICKENING
CLOUDS ALONG WITH DEVELOPING LIGHT PCPN BY DAYS END.  THE MODELS
CONTINUE TO HAVE DIFFICULTIES IN THEIR HANDLING OF A CLOSED LOW
DROPPING SWD JUST OFF THE WEST COAST THIS UPCOMING WEEKEND.  THE GFS
KEEPS THIS SYSTEM AS A MORE OPEN AND PROGRESSIVE WAVE WITH MORE OF A
PHASING OF THE NRN AND SRN STREAMS.  THE CANADIAN AND ECMWF SOLNS
ARE MUCH SLOWER AND LESS PHASED AND KEEP MORE AN UPR RDG AXIS ACROSS
OUR CWA.  EITHER WAY...ALL SOLNS CONTINUE TO PROG A SIGNIFICANT
INCREASE IN MOISTURE WITH BOTH A GULF AND PACIFIC TAP EXPECTED. A
BROAD DIVERGENT FLOW IS EXPECTED TO MAINTAIN SYNOPTIC ASCENT THROUGH
EARLY NEXT WEEK. LOW LVL BAROCLINICITY IS EXPECTED TO FURTHER AID IN
PCPN DEVELOPMENT AS A COASTAL TROUGH/WARM FRONT BECOMES MORE
PRONOUNCED THROUGH MONDAY ACROSS THE SERN PORTION OF THE CWA.  THE
TIMING OF THE ACTUAL COLD FRONT WL REMAIN DIFFICULT BUT FOR NOW WL
GO WITH A LATE MON/TUE MORNING FROPA PER THE LATEST GFS SOLN.  WL
INCREASE POPS SLIGHTLY TO THE GOOD CHC CATEGORY FOR MONDAY WITH AN
UNDERSTANDING THAT LKLY/CAT POPS MAY EVENTUALLY BECOME NECESSARY.
OTHER THAN FRI...MOST OF THE FCST PD IS EXPECTED TO BE BELOW NORMAL
FOR A CHANGE GIVEN THE TWO COLD FRONTS EXPECTED AND THE ABUNDANT
CLOUD CVR/RAIN CHANCES.
