RADAR IMAGERY SHOWS SCATTERED SHOWERS PINWHEELING AROUND THIS

COASTAL SOUTHERN CA FROM LOS ANGELES TO SAN DIEGO...WHILE ANOTHER
LINE OF SHOWERS MOVING TOWARD THE SOUTHWEST IS SET UP IN A
DEFORMATION ZONE GENERALLY JUST SOUTH OF I-80 FROM NORTHERN NV TO
THE NORTHERN SAN JOAQUIN VALLEY AND EVENTUALLY THE SF BAY AREA. SO
FAR...PRECIP GAUGES SINCE 05/12Z ARE REPORTING LIGHT AMOUNTS NEAR OR
LESS THAN 0.10-INCH.
