EVENT...MOST CONCERN JUST AHEAD OF ACTIVE VORT OVER FAR S CA AND AZ...
.
SATELLITE ANALYSIS AND TRENDS...DEEP MOISTURE NEAR OR JUST BEHIND
CURRENT CONVECTION IN C TO INTERIOR W AZ AND SE CA.  GRADIENT PW AREAS
AND INCREASED PWS TO CONTINUE TO PLAY A ROLE OUT AHEAD ACROSS N AZ...
S UT...S NV AND INTERIOR S AND SE CA INTO THE FAR S SIERRAS THRU THIS
AFTERNOON INTO THIS EVENING.  ENOUGH FORCING MOVING THRU C AZ AND EXT
S  AND SE CA AND FEEDING ON VERY HIGH MOISTURE CONTENT AND SHARP MOISTURE
GRADIENT FOR CONVECTION TO CONTINUE...IN A SLIGHTLY WEAKER FORM NOW IN
AZ AND INCREASED STATE IN SE CA...RIVERSIDE INTO
S SAN BERANRDINO COUNTY.  HIGHLY DIFFLUENT FLOW ALSO HELPING IGNITE
AND KEEP CONVECTION GOING LONGER THAN DIURNAL NORMAL AND CAN IMAGINE
HOW ACTIVE THINGS CAN GET AHEAD OF VORTS WITH ADDED HEATING THRU
THE CLOUDS AS THE DAY GOES ON ACROSS MOUNTAINS AND DESERTS OF S CA
INTO S SIERRAS AND ACROSS S TO E CENTRAL NV...N AND NW AZ INTO S UT.
BEST UPPER LEVEL DIVERGENCE S CA THRU S NV/NW AZ INTO S UT AND MOISTURE
CONTINUES TO GET PUMPED IN FROM FAUSTO OVER 1000 MILES AWAY TO THE SOUTH.
THESE PREDECESSOR RAIN EVENTS HAVE BEEN WRITTEN UP IN THE LITERATURE
FROM RESEARCHERS AT STATE UNIVERSITY OF NY AT ALBANY AND HVY RAINS ACROSS
THE AREA CAN BE CONSIDERED AT LEAST AN INDIRECT RESULT OF THIS.
OF IMMEDIATE CONCERN IS CONVECTION IN AZ CONTINUE TO LIFT NORTH THRU
CENTRAL AND W CENTRAL AZ AND ACTIVE CLUSTERS GIVING ONE INCH PER 30-45
MINUTES IN RIVERSIDE INTO NOW S SAN BERNARDINO COUNTY AND SETTING UP A
GOOD OUTFLOW BOUNDARY FOR ADDITIONAL STORMS THIS AFTERNOON AND EVENING
FROM THE MOUNTAINS AND EAST AND NE FROM C SAN DIEGO COUNTY TO KERN COUNTY.
