SCATTERED RW/TRW ACROSS COASTAL AREAS OF SE TX AT THIS TIME AS
INTERACTION OF OUTFLOW BOUNDARY FROM EARLY MORNING ACTIVITY TO OUR N
AND NW...UPPER LEVEL JET...WEAK SHORTWAVES...AND AFTERNOON HEATING
ASSIST IN DESTABLIZATION OF THE ATMOSPHERE.  MODELS CONTINUE TO POINT
TO SHORTWAVES MOVING ACROSS THE AREA THU AND FRI.  THESE DISTURBANCES
ALONG WITH HIGH MOISTURE LEVELS (PRECIP WATERS 1.75 TO 2.00 INCHES
AND MEAN RH VALUES >70%) AND LI/S AROUND -5 SHOULD KEEP RW/TRW
CHANCES NEAR FWC NUMBERS BOTH THU AND FRI.  BEST CONCENTRATION SHOULD
BE DURING THE DAYS AS AFTERNOON HEATING KICKS IN.

WILL GO WITH FWC POPS BUT WILL MAKE A FEW ADJUSTMENTS ON TEMPS.  THE
TEMP FORECAST COULD BE TRICKY DEPENDING ON RW/TRW LOCATION (2 PM
