DISCUSSION
RAIN SHOWERS AND POTENTIALLY A FEW THUNDERSTORMS ASSOCIATED WITH A
WARM FRONT LEAVE THE AREA LATE IN THE MORNING, BEFORE ANOTHER ROUND
OF SHOWERS POTENTIALLY MOVES INTO THE AREA BY THE AFTERNOON AS COOLER
AIR DROPS IN FROM THE NORTH. SOME MARINE FOG COULD BE SEEN DURING THE
MORNING HOURS UNDER THE WARM AIR REGIME. HOWEVER, ONCE THE WINDS VEER
BY THE LATE MORNING/AFTERNOON HOURS WITH THE INCOMING COOLER AIR,
EXPECT ANY FOG TO BEGIN TO CLEAR OUT. WHILE SUSTAINED WINDS OF
AROUND 15 KNOTS ARE EXPECTED IN THE WARM AIR REGIME AND THEN AGAIN
WHEN THE COOL AIR MOVES IN FROM THE NORTH LATER IN THE AFTERNOON,
GIVEN THE STABLE MARINE LAYER ABOVE THE WATER, WIND GUSTS AREN'T
EXPECTED TO BE ALL THAT MUCH HIGHER THAN THE SUSTAINED WINDS.
