LARGE UPPER TROUGH REMAINS OFF THE CA COAST THIS MORNING...WITH
SERIES OF SHORTWAVE TROUGHS ROTATING INLAND.  THE FIRST UPPER SYSTEM
IS CURRENTLY OFF THE SOUTHERN CA COAST.  THIS FEATURE WILL TRACK
INLAND LATER THIS MORNING.  LIGHTNING NETWORK DATA INDICATES
EMBEDDED THUNDERSTORMS WITH THIS SYSTEM...IN REGION OF COLD UPPER
TEMPERATURES AND STRONG UVVS.  PRESENT INDICATIONS ARE THAT THERE
WILL BE SOME RISK OF GUSTY/DAMAGING WINDS AND HAIL TODAY IN STRONGER
STORMS ACROSS PARTS OF SOUTHERN AND CENTRAL CA.  STRONG VERTICAL
SHEAR PROFILES AND TOPOGRAPHIC EFFECTS COULD ALSO RESULT IN A
LOCALIZED THREAT OF BRIEF TORNADOES.  VERY MARGINAL INSTABILITY IS
THE PRIMARY MITIGATING FACTOR FOR SEVERE STORMS...AND A CATEGORICAL
OUTLOOK WILL NOT BE ISSUED AT THIS TIME.

ANOTHER STRONG SHORTWAVE TROUGH IS FORECAST TO ROTATE INLAND THIS
EVENING OVER ROUGHLY THE SAME AREA.  AS WITH THE FIRST SYSTEM...
POTENTIAL WILL EXIST FOR GUSTY WINDS AND/OR A BRIEF TORNADO.
