.DISCUSSION...

AN AREA OF STRATUS HAS DEVELOPED ACROSS FAR EASTERN
AREAS...OTHERWISE CLEAR SKIES SO FAR TONIGHT. WILL SEE
SOME OTHER PATCHES OF LOW CLOUDS LIKELY DEVELOP TOWARD
MORNING AND A FEW PATCHES OF FOG AS WELL WHERE DW PTS ARE
IN THE MID 50S TO LOWER 60S.

DID NOT MAKE SIGNIFICANT CHGS TO THE ONGOING FCST CONCERNING
THE MID/UPPER TROUGH AND PRECIP CHCS TUE NIGHT THROUGH WED. HAVE
TRENDED THE PRECIP FCST TOWARD THE ECMWF SOLN WHICH DEPICTS
ORGANIZED CONVECTION MOVING INTO THE W/SW AREAS LATE TUE NIGHT
AND PRECIPITATION EXPANDING ACROSS THE AREA ON WED...THEN SHIFTING
E/NE ON WED EVE. BELIEVE MOISTURE LEVELS AND SYNOPTIC SCALE LIFT
WILL SUPPORT LOCALLY HEAVY RAINFALL ON WED ACROSS SE TX.

MODELS ARE IN GOOD AGREEMENT THAT A COLD FRONT WILL MOVE ACROSS
THE AREA ON FRI NIGHT WITH A SLIGHT CHC/CHC OF PRECIP NEAR AND
BEHIND THE BOUNDARY. LOOKS LIKE THE SW FLOW ALOFT WILL CONTINUE
TO BRING UPPER LEVEL DISTURBANCES ACROSS SE TX AND SUPPORT A CHC
OF RAIN THROUGH EASTER WEEKEND. 33

.MARINE...
A FAIRLY TIGHT PRESSURE GRADIENT WEST OF FREEPORT WAS HELPING TO
GENERATE CAUTION CONDITIONS EARLY THIS MORNING. THE MODEL DATA
DIMINISHED THE WINDS TOWARD SUNRISE. ANOTHER PERIOD OF MODERATE
WINDS IS POSSIBLE AGAIN TONIGHT. OTHERWISE...ONSHORE WINDS WILL
PERSIST THROUGH THE MID WEEK PERIOD.
