.
SATELLITE ANALYSIS AND TRENDS...CNVTN HAS BEEN PULSING PAST SEVERAL HRS
ACRS SRN CA (PORTIONS OR ORANGE..SAN DIEGO..RIVERSIDE AND SAN BERNARDINO)
AS INFERRED FROM CLD TOP TEMPS. CNVTN HAS BEEN SLOW MVG IN RESPONSE TO
VERY WEAK LO/MID LEVEL FLOW AS PER 12Z RAOBS AND MODEL GUIDANCE. CLD
TOP TEMPS ARE REACHING -52C SUGGESTING TOPS TO 200MB.
.
CNVTN HAS RESPONDED TO A MARKED INCR IN MOISTURE FROM YDAY AS 1.4" AMNTS
ARE DEPICTED REACHING NRN KERN AND SAN BERNARDINO AND 2" VALUES NR THE
MEXICAN BORDER AS PER GOES AND GPS. THESE VALUES ARE ARND 200 PERCENT
OF NORMAL. MOISTURE IS BEING DRAWN N BY UPR LOW SPINNING OFF THE COAST
S OF THE CHANNEL ISLANDS.
.
GOES WV LOOP INDICATES THAT UPR LOW HAS REACHED IT/S WESTERNMOST
EXTENT AND IS NOW SHOWING AN EWRD COMPONENT. LATEST TRENDS SUGGEST
IT WILL TRACK OVER/NEAR SANTA CATALINA AND THEN MOVE INTO LOS ANGELES
COUNTY. COMBINATION OF UPR LO AND DEEP MOISTURE IN PLACE SHOULD KEEP
CNVTN GOING THROUGH THE AFTN/EVE NOT JUST OVER THE MOUNTAINS BUT ALSO
REACHING VALLEY LOCATIONS.
.
SATELLITE ESTS SUGGEST MAX HLF HR RAINFALL UNDER THE CELL CORES UP TO
THREE QUARTERS OF AN INCH.
.
QUICK LOOK AT 1930Z IMAGE SHOWS STUBBORN CELL OVER S CENTRAL SAN
BERNARDINO REMAINS NEARLY ANCHORED IN PLACE. CLUSTER OF CELLS OVER WRN
RIVERSIDE ARE LIFTING N AND WEAKENING/WARMING. THE CELL OVER CENTRAL
RIVERSIDE N OF THE SALTON SEA HAS WEAKENED AND LIFTED N. THE CELLS ALG
THE RIVERSIDE..SAN DIEGO BORDER JUST W OF THE SALTON SEA HAVE INCREASED
WITH CLD TOP TEMPS COOLING AND ADL CU DEVELOPING AND FEEDING INTO IT.
