AS MESONET OBSERVATIONS STILL SHOWING A DRY AIR MASS THOSE AREAS WITH
DEWPOINTS AROUND 20 ALTHOUGH MOST CURRENT TEMPS ABOVE FREEZING. MODEL
GUIDANCE SHOWS THE COLD DRY AIR SLOWLY ERODING THU MORNING WHICH MAY
BE JUST ENOUGH TO PREVENT SIGNIFICANT FREEZING RAIN AS THE NEXT

RIDING A 170 KT JET STREAK. GFS MODEL HAS SW 850 MB WINDS OF 55 KT
IMPINGING ON NORTHERN COAST RANGE MONDAY FOR POTENTIALLY HEAVY QPF
THERE. THE JET WILL BE NORTH OF OUR AREA SO EXPECT FREEZING LEVELS
