VALID 150100Z - 151200Z
..NO TSTM AREAS FORECAST...
..ORE AND NRN CA COASTS...
VISIBLE AND WATER VAPOR SATELLITE IMAGERY INDICATE A COMPACT
VORTICITY MAXIMUM APPROACHING THE SWRN ORE/NWRN CA COASTS AS OF
0030Z. SOME DEEPENING OF CUMULUS CONVECTION HAS OCCURRED WITHIN
ASSOCIATED ZONE OF STRONGER FORCING FOR ASCENT JUST OFFSHORE...BUT
NO LIGHTNING HAS BEEN OBSERVED. 00Z MEDFORD SOUNDING SHOWED RATHER
STEEP LAPSE RATES THROUGH THE LOWEST 3-4 KM AGL WITH AN MUCAPE OF
AROUND 60 J/KG. HOWEVER...THIS POSITIVE BUOYANCY WAS LARGELY
OBSERVED BELOW THAT PORTION OF THERMODYNAMIC PROFILE SUPPORTIVE OF
CHARGE SEPARATION.
WHILE A FEW LIGHTNING STRIKES ARE POSSIBLE AS VORTICITY MAXIMUM AND
ATTENDANT CONVECTIVE DEVELOPMENT MOVE ONSHORE...THE ANTICIPATED
AREAL COVERAGE APPEARS TOO SMALL TO WARRANT INCLUSION OF A GENERAL
THUNDER AREA.
