DEEP STACKED LOW OFF THE CENTRAL COAST OF CALIFORNIA...A POWERFUL 300MB JET SOUTH OF SAN DIEGO AND LOTS OF MOISTURE. SEVERAL REPORTS OF LARGE HAIL AND WIND DAMAGE PROMPTED THE ISSUANCE OF SEVERAL SEVERE THUNDERSTORM WARNINGS THIS EVENING. IN ADDITION TO THE WIND AND HAIL..VERY HEAVY DOWNPOURS WERE BEING REPORTED THROUGHOUT THE REGION. ONE GAGE REPORTED 4 TENTHS OF AN INCH IN LESS THAN TEN MINUTES. SOME OF THE HEAVIEST AMOUNTS WERE NEAR THE MORRIS BURN AREA WHICH PROMPTED THE ISSUANCE OF A FLASH FLOOD WARNING FOR DEBRIS FLOWS FOR THAT AREA. WE MAY SEE A FEW BREAKS OVERNIGHT...BUT RADAR...SATELLITE AND LIGHTNING DATA INDICATES THAT THE THUNDERSTORM ACTIVITY WILL CONTINUE OVERNIGHT. THEREFORE THE THREAT FOR SEVERE WEATHER...ALONG WITH FLASH FLOODING AND DEBRIS FLOWS IN ALL THE BURN AREAS...WILL CONTINUE AT LEAST THROUGH THE NIGHT. ALONG WITH THE RAIN...HEAVY SNOW IS FALLING IN THE MOUNTAINS. ONE SPOTTER IN NORTHERN VENTURA COUNTY REPORTED 18 INCHES OF SNOW IN THE LAST 12 HOURS...WITH HEAVY SNOW CONTINUING. AT THE HIGHER LEVELS... SNOW WILL BE MEASURED IN FEET. SNOW LEVELS ARE RIGHT AROUND 4000 FEET CURRENTLY...BUT AS THE COLDER AIR MOVES IN TONIGHT THOSE SHOULD FALL TO 3000 FEET...WITH POSSIBLY SOME NON-STICKING SNOW AS LOW AS 2500 FEET ASSOCIATED WITH CONVECTIVE ACTIVITY.
