.DISCUSSION...
ONSHORE FLOW HAS RESUMED AND DEWPOINTS ARE ON THE RISE. NOT
EXPECTING MUCH OF A TEMP DROP...IF AT ALL...OVERNIGHT. PRECIP
ASSOCIATED WITH TAIL END OF SHORTWAVE AXIS MOVING INTO PLAINS
WILL SKIRT ACROSS N ZONES LATER THIS AFTN AND EVNG. MOISTURE/PRECIP
ORIENTATION SHOULD BECOME MORE WSW-ENE ORIENTED OVERNIGHT AS IT
SAGS CLOSER TO THE COAST.

CONTINUED SCT PRECIP COVERAGE ACROSS SRN 1/4 TO 1/2 PART OF THE
REGION ON THURS WITH REMNANT MOISTURE IN PLACE ALONG WITH WARM
FRONT MEANDERING ABOUT. GENERALLY LIGHT NUISANCE AMOUNTS...BUT
ENOUGH FOR A GLOOMY DAY THAT ARE FAIRLY TYPICAL ONCE THE WARM
SECTOR PUSHES INLAND. HIGHS ON THURS WILL BE TRICKY DEPENDING ON
THE BOUNDARY POSITIONING. ALSO ADDED MENTION OF SEA FOG CLOSER TO
COAST THRU FRI.

ATTENTION THEN TURNS TO SYSTEM CURRENTLY DIGGING DOWN WEST COAST.
IT SHOULD PUSH ACROSS NRN MEXICO AND INTO TX THURS NIGHT AND FRI.
INCREASING LARGE SCALE ASCENT...PW`S AROUND 1.6"...AND SFC WAVE
DEVELOPING ALONG WARM FRONT SHOULD ALLOW FOR RAPID INCREASE IN
PRECIP COVERAGE LATE THURS NIGHT...CONTINUING INTO FRI AFTN UNTIL
THE SYSTEM EXITS THE AREA OFF TO THE EAST ALER IN THE DAY. MOST
OF MODEL GUIDANCE STILL INDICATES POTENTIAL FOR 1-2" NORTH OF
I-10...AND LESS THAN 1" SOUTH OF THERE. WOULDN`T ANTICIPATE VERY
MANY ISSUES W/ THAT SHOULD IT VERIFY. INSTABILITY IS LACKING SO
SVR THREAT LOOKS MINIMAL...BUT ALWAYS WORTH KEEPING AN EYE ON
CLOSER TO THE WARM FRONT.

COLD FRONT PUSHES OFF THE COAST FRI EVNG IN THE WAKE OF THIS
SYSTEM....BRINGING A COOL DRY WEEKEND. ONSHORE FLOW SHOULD RESUME
EARLY NEXT WEEK.

RIDGE OFF THE WEST COAST AMPLIFIES EARLY NEXT WEEK ALLOWING FOR
DEEPENING TROF ACROSS NATIONS MID SECTION. LOOKING FOR ANOTHER
FRONT TO PUSH THRU ON TUE...PROBABLY A MOSTLY DRY FROPA WITH
LIMITED TIME FOR MOISTURE RETURN. COOL AND DRY AGAIN THRU XMAS
EVE. PRELIMINARY GUESS FOR XMAS IS FOR WARMER CONDITIONS...
INCREASING CLOUDS...BREEZY SOUTHERLY WINDS...AND POSSIBLY SOME
DRIZZLE. STILL A LONG WAYS OFF WX-WISE THOUGH. 47

&&

.MARINE...
WINDS TONIGHT MAY INCREASE ENOUGH TO REACH SCEC CRITERIA. A WARM
FRONT WILL MOVE ONSHORE ON THURSDAY AND BRING CHANCES FOR SEA FOG
FORMATION LATE THURSDAY AND EARLY FRIDAY. A COLD FRONT WILL THEN
PUSH OFFSHORE FRIDAY EVENING. WINDS BEHIND THE FRONT SHOULD REACH
ADVISORY LEVELS OVER THE GULF WATERS FRIDAY NIGHT INTO EARLY
SATURDAY MORNING. 40
