AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 PM PDT MON JUN 30 2008

.SYNOPSIS...A SHALLOW MARINE LAYER WILL CONTINUE COASTAL LOW CLOUDS
AND FOG DURING THE NIGHTS AND MORNINGS. MID LEVEL MOISTURE WILL
CAUSE A FEW CLOUDS OVER THE MOUNTAINS AND DESERTS DURING THE
AFTERNOONS. OTHERWISE...HIGH PRESSURE WILL KEEP THE WEATHER FAIR
WITH WARM TO HOT DAYS INLAND.

&&

.DISCUSSION...FOR SOUTHWEST CALIFORNIA INCLUDING SAN DIEGO...
ORANGE...SOUTHWEST SAN BERNARDINO AND WEST RIVERSIDE COUNTIES.

.SHORT TERM (TONIGHT-THU)...SKIES WERE CLEAR THIS EVENING EXCEPT FOR
STRATUS OFFSHORE. THE 00Z NKX SOUNDING HAD AN INVERSION BASED NEAR
1500 FT WITH A LITTLE MID LEVEL MOISTURE BUT DRY SW WINDS ALOFT.
MODERATELY STRONG ONSHORE GRADIENTS WITH ABOUT 8 MB SAN-IPL.

UPPER LEVEL HIGH PRESSURE WILL REMAIN OVER THE SW WITH A TROUGH IN
THE ERN PAC THAT WILL SLOWLY SHIFT NE. THIS WILL RESULT IN
RELATIVELY MINOR CHANGES IN THE SHORT TERM WITH TEMPS ABOVE SEASONAL
AVERAGES IN MOST AREAS. THE WARMER INLAND VALLEYS WILL BE ABOUT
5 TO 10 DEGREES ABOVE NORMAL TUE AND WED WITH HIGHS IN THE MID 90S
TO NEAR 100. THE LOWER DESERTS WILL REMAIN HOT WITH MAX TEMPS NEAR
115 DEGREES. SLIGHTLY COOLER THU AS THE HIGH SHIFTS E. MID LEVELS
ARE EXPECTED TO DRY A LITTLE WHICH WILL REDUCE THE AMOUNT OF CU OVER
THE MOUNTAINS DURING THE AFTERNOONS. THE MARINE LAYER WILL REMAIN
SHALLOW WITH LOW CLOUDS AND FOG CONFINED TO THE COASTAL AREAS DURING
THE NIGHTS AND MORNINGS EXCEPT POSSIBLY INTO THE FAR WRN SAN DIEGO
INLAND VALLEYS. AFTERNOON SEA BREEZES WILL MODERATE MAX TEMPS NEAR
THE COAST AND WILL CAUSE LOCALLY WINDY CONDITIONS IN THE MOUNTAINS
AND DESERTS.

&&

.LONG TERM (FRI-MON)...THE E PAC TROUGH WILL MOVE PAST TO THE NORTH
LATE IN THE WEEK BUT WILL HAVE LITTLE IMPACT ON LOCAL WEATHER. THE
HIGH REBUILDS EARLY NEXT WEEK FOR RENEWED WARMING. THERE SHOULD BE
AN INCREASE IN MID LEVEL MOISTURE AS THE WINDS ALOFT TURN MORE SE
EARLY NEXT WEEK. THIS WILL RESULT IN MORE AFTERNOON CLOUDS OVER THE
MOUNTAINS. HOWEVER...PROGS HAVE BEEN INCONSISTENT WITH THIS MOISTURE
SO WILL CONTINUE TO INDICATE LOW POPS BUT NO THUNDERSTORMS...YET.
