LOOK RATHER FAVORABLE FOR SOME PATCHY FOG TOWARD SUNRISE. VFR

DISCUSSION...
LOW LEVEL MOISTURE WILL CONTINUE TO INCREASE STEADILY ACROSS SE
TX THESE NEXT COUPLE OF DAYS AS MODERATE ONSHORE WINDS PERSIST.
PATCHY FOG POSSIBLE FOR SOME AREAS POSSIBLE TONIGHT THROUGH SUN
MORNING. LINGERING DRY AIR ALOFT TO WILL HELP KEEP RAIN CHANCES
RATHER LIMITED AS THE NEXT UPPER TROF APPROACHES FROM THE WEST.
WHILE THE BEST LIFT LOOKS TO REMAIN JUST N/NW OF THE CWA ON MON
WITH THIS FEATURE...ISO COVERAGE IS POSSIBLE THROUGH MON NIGHT/
EARLY TUES WITH THE PASSAGE OF A WEAK COOL FRONT. THIS BOUNDARY
SHOULD BRING A RETURN OF A DRIER (BUT ONLY SLIGHTLY COOLER) AIR
MASS TO THE REGION BRIEFLY.

UPPER LEVEL RIDGING IN THE WAKE OF THIS 1ST PART OF THE WEEK WX
SYSTEM EXPECTED TO FLATTEN/SHIFT FURTHER EAST BY WEEKS END. THE
RESULTING ZONAL TO SLIGHT SWLY FLOW ALOFT COULD OPEN US UP TO A
POSSIBLE EMBEDDED SHORTWAVE(OR TWO). THIS COMBINED WITH THE RE-
TURN OF ONSHORE WINDS/INCREASING MOISTURE SEEMS TO SUPPORT IDEA
OF LOW POPS STARTING LATE THUR (AND MAYBE ON THROUGH NEXT WEEK-
END?). 41

MARINE...
LIGHT TO MODERATE SOUTHERLY WINDS SHOULD PERSIST THROUGH TUESDAY
WITH LOW SEAS. A WEAK FRONT WILL PUSH TO THE COAST AND THEN STALL
ON TUESDAY WHICH WILL TURN WINDS ALONG THE UPPER TX COAST TO THE
SOUTHWEST. SOUTHERLY WINDS THEN INCREASE AGAIN THURSDAY INTO
FRIDAY AS LOW PRESSURE FORMS IN THE THE PLAINS. SEA HEIGHTS SHOULD
REMAIN RELATIVELY UNCHANGED AT LOW LEVELS THE NEXT FEW DAYS.
