DISCUSSION
NORTHERLY WINDS HAVE SUBSIDED SUBSTANTIALLY SINCE WHAT
WAS EXPERIENCED OVER THE WEEKEND. WINDS WILL GENERALLY TURN
BREEZY IN THE AFTERNOONS THIS WEEK. OVERNIGHT LOWS WILL BE ON THE
CHILLY SIDE AGAIN TONIGHT, BUT WILL BEGIN MODERATING THIS WEEK
WITH BUILDING HIGH PRESSURE. SOME AREAS OF LOCALIZED FROST WILL
BE POSSIBLE IN THE HAYFORK AND LARABEE VALLEY TUESDAY MORNING.
CONDITIONS WILL REMAIN VERY DRY WITH WARMING TEMPERATURES THROUGH
THE WEEK. HIGHS WILL MOST LIKELY TOP OUT AROUND 90 FOR THE INTERIOR
ON THURSDAY. THIS WILL CONSTITUTE ONLY A MINOR HEATRISK FOR THIS
TIME OF YEAR. HOTTER TEMPERATURES WILL HELP REFORM A MARINE
INVERSION AND WILL INCREASE CHANCES FOR COASTAL STRATUS AND FOG.

DIRECTION MEETING THE CRITERIA FOR WIND SHEAR. /EYS
