UPDATES...LAST MINUTE DECISION BASED ON CLEARING TREND OF LOW CLDS
IN LA CSTL VLYS.

PROBLEM OF THE DAY...POSN/TRACK OF UPPER LOW AND RESULTANT LOW
CLOUD COVERAGE IN NXT 48 HRS...

FOR THE NEAR TERM...LOW CLOUDS HAVE ACTUALLY PUSHED INTO THE LA
CNTY VLYS...BUT CLRNG TREND ALREADY BEGINNING SO AN UPDATE MAY BE
TOO LITTLE TOO LATE...WILL LEAVE OPEN FOR LAST MINUTE DECISION.

FOR THE NEXT 48 HOURS...UPR LOW PROGGED BY MDLS TO SLOWLY DRIFT E
AND APPROACH THE CST. THE SLOWEST MODEL...ETA...PREFERRED. AS LOW
MOVES TOWARD THE CST...DCRSNG HGTS/THKNSS WILL CAUSE DCRSNG TEMPS. 

CHC FOR SHRA...DYNAMICS AND LOW LVL INFLOW WL BE WK WITH AVBL 
MSTR SOMEWHAT LIMITED AS WELL...SO WOULD NOT EXPECT IT TO
BE MUCH OF A RAINFALL PRODUCER...AS MENTIONED IN LAST DISCUSSION.
THERE IS THE POSSIBILITY OF AN ISOLATED MTN SHRA ON WED. WINDS WILL
BE ON THE INCREASE WED AFTN...ESPECIALLY IN THE HIGH DESERTS.

LOW CLOUDS WILL BE ON THE INCREASE THRU WED AND PERSIST INTO THU
MRNG...ALTHOUGH THE STRENGTH OF THE MARINE INVERSION MAY BE TESTED
AS THE UPR LOW MOVES INTO THE REGION. 1 KM VIS SAT LOOP SHOWS AN
EDDY SPINNING IN THE HISTORICALLY FAVORED POSITION...NEAR CATALINA.
IT MAY BE NECESSARY TO INCREASE LOW CLOUD COVERAGE IN AFTN PACKAGE.
DEPENDING ON THE DEPTH OF THE MARINE LAYER...THE VLYS WILL HAVE
TROUBLE CLEARING ON WED AND/OR THU AFTN.

XTNDD...UPPR LOW OFF THE WEST COAST WITH MINIMAL EFFECT ON SRN CA
WX...MOSTLY CLEAR AND SEASONABLE TEMPS LOOK GOOD FOR NOW.

SMX 00- LAX 000. SWEET.

.LAX...NONE.
