.DISCUSSION...
AS DAYTIME HEATING COMMENCES EXPECT WINDS TO BECOME SOUTHEAST WITH SOME
GUSTS NEAR 20. THESE WINDS WILL AID IN BRINGING IN MORE MOISTURE INTO THE
AREA. ALSO EXPECT A SLIGHT CHANCE OF THUNDERSTORMS...MUCH LIKE
THE SUMMERTIME VARIETY. DO NOT EXPECT THE COVERAGE OF THUNDERSTORMS TO
BE AS WIDESPREAD SUMMER THOUGH.  EXPECT GUSTY WINDS FROM THUNDERSTORMS
THAT DO DEVELOP. I EXPECT THE CHANCES FOR FOG DEVELOPMENT TOMORROW
MORNING TO BE MODERATE.  WE DO NOT SEE MUCH OF A CHANGE IN THE PATTERN
FROM TODAY AND WE SAW FOG DEVELOP NEAR THE AREA TODAY.
