.DISCUSSION...

A MIX OF CU AND CIRRUS ACROSS THE SE THIRD OF SE TX THIS AFT WITH
SUNNY SKIES ACROSS NW AREAS. A FEW SHWRS ARE PRESENT IN CENTRAL
TX AND ARE ASSOCIATED WITH A MID/UPPER SHRT WV. TEMPS ARE
GENERALLY 75 TO 80 INLAND EARLY THIS AFT WITH GUSTY S/SE WINDS AS
THE PRESSURE GRADIENT BEGINS TO TIGHTEN DUE TO A SFC LOW DEEPENING
ACROSS SW OKLA. MAY SEE SOME ISO SHWRS/TSTMS ACROSS NW AREAS THIS
EVE...BUT THE MAJORITY OF THE PRECIP WILL BE ASSOCIATED WITH THE
FRONT.

THE COLD FRONT WHICH WILL BRING A GOOD CHC OF SHWRS/TSTMS TO SE
TX LATE TONIGHT AND THU AM IS PUSHING THROUGH THE TX PANHANDLE
THIS AFT. THERE ARE SOME MODEL TIMING DIFFERENCES WITH THE FRONT.
THE GFS BEING THE FASTEST AND PREFERRED MODEL. EXPECT THE FRONT TO
ENTER NW AREAS 5-6 AM AND NEAR SW COASTAL AREAS 9-10 AM. EXPECT
SCT SHWRS/TSTMS ALONG THE FRONT WITH BETTER COVERAGE AS THE
BOUNDARY APPROACHES THE COAST IN THE MORNING. SHWRS/TSTMS ARE
LIKELY ACROSS COASTAL AREAS AND OFFSHORE. MOST PRECIP SHOULD BE
EAST OF SE TX AROUND MID-DAY THU. WE WILL SEE BELOW NORMAL TEMPS
ON FRIDAY...NEAR NORMAL SATURDAY...AND THEN BACK TO ABOVE NORMAL
SUNDAY AND MONDAY.

THE ECMWF AND GFS STILL DIFFER GREATLY WITH OUR NEXT STORM SYSTEM
ON TUE. SUCH IS OFTEN THE CASE DURING THE TRANSITION SEASON IN
THE EXTENDED FORECAST PDS. THE ECMWF IS MUCH FURTHER SOUTH AND
SLOWER THAN THE GFS. FOR NOW WILL CONTINUE WITH A COMPROMISE SOLN
AND ADVERTISE CHC POPS. STAY TUNED. 33

.MARINE...
LIGHT TO MODERATE SOUTHEAST TO SOUTH WINDS WILL PERSIST THROUGH TONIGHT.
DURING THE MORNING THROUGH EARLY AFTERNOON HOURS ON THURSDAY...WINDS WILL
SHIFT TO THE NORTHWEST AND NORTH AFTER THE PASSAGE OF A STRONG COLD FRONT.
BEHIND THE FRONT...CAUTION FLAGS WILL LIKELY BE NEEDED FOR THE BAYS AND
NEARSHORE WATERS AND ADVISORIES WILL LIKELY BE NEEDED FOR THE OFFSHORE
WATERS DUE TO THE MODERATE TO STRONG OFFSHORE WINDS AND BUILDING SEAS.
LIGHT TO MODERATE ONSHORE WINDS RETURN TO THE AREA OVER THE WEEKEND WITH
SEAS POSSIBLY GETTING BACK UP TO CAUTION LEVELS EARLY NEXT WEEK.  42
