THIS AHEAD OF OPENING UPPER LOW IN NRN CA. STRONG VORT SEEN ON WV IMAGERY ON SE SIDE OF LOW WITH JET SUPPORT APPARENT. ONE STORM RATHER STRONG FOR THE OVERNIGHT PERIOD NOW MOVING INTO SE ORE. MODELS HAVE INITIALIZED THIS FEATURE WELL...AND AGREE ON TRACK...BUT BELIEVE THEY ARE A LITTLE TOO QUICK TO SCOUR THE MOISTURE OUT. THIS IS A TYPICAL BIAS...ESP FOR NORTHEAST ZONES. FOR NOW...WILL CONTINUE WITH SCT ACTIVITY IN HUMBOLDT CTY TO COVER CURRENT ACTIVITY AND SHOULD QUIET DOWN THERE AROUND NOON. BAND SHOWLD MOVE EWD. ACTIVITY SHOULD GET STRONGER WITH HEATING.

SEVERE POTENTIAL IS THERE IN LATE MORNING TO EARLY AFTERNOON AND WILL HAVE TO WATCH. EARLIER THINKING WAS THAT THIS WOULD BE TOO FAR NORTH... BUT STORMS ARE GETTING STRONGER PER 88D IMAGERY ATTM. GOOD SHEAR... BUT WITH RELATIVELY DRY LLVLS EXPECT MAINLY MICROBURST POTENTIAL ESP WITH STORM MOTION OF 35-40 KTS. AFTER TODAY...NOT MUCH TO TALK ABOUT AS FLOW VEERS TO THE WEST AND SHOULD DRY ALL AREAS OUT BY MIDNIGHT. ONLY TOKEN POPS IN THE NORTHEAST THIS EVENING AS DRYING SHOULD WORK IN QUICKLY. GENERAL WEST FLOW UNDER FLAT RIDGE THIS WEEKEND WITH TEMPS ABOUT 10-15 DEGS COOLER THAN PAST COUPLE DAYS BUT STILL ABOVE NORMAL. EXTENDED...RIDGE TO AMPLIFY A BIT OVER THE WEEKEND JUST OFF THE COAST. MAY HAVE SOME MORE NW FLOW FOR COOLER TEMPS...BUT NOT SURE.
