HIGHEST TOTALS OVER NW SONOMA COUNTY. CANT COMPLETELY RULE OUT A
HUNDREDTH OR TWO ON THE SF PENINSULA SO HAVE KEPT SOME SLIGHT
CHANCE POPS GOING THERE THROUGH MIDDAY. FRONTAL BOUNDARY IS
ASSOCIATED WITH IMPRESSIVE SYSTEM THAT PRODUCED HEAVY RAIN OVER
THE PACIFIC NW THIS WEEKEND. STRONG JET STREAM ENERGY HAS NOW
PUSHED INTO THE NORTHERN ROCKIES AND LEFT THE FRONTAL BOUNDARY
MORIBUND AND VOID OF UPPER SUPPORT AS COLD ADVECTION WILL STAY
NORTH OF THE BAY AREA. THUS THE FRONTAL SYSTEM WILL WASH OUT WITH
LITTLE FAN FARE BY LATER THIS AFTERNOON.
