.DISCUSSION...

MUCH OF THE AREA SHOULD SEE SOME DRYING CONDITIONS FOR THE NEXT
SEVERAL DAYS AS HIGH PRESSURE BUILDS IN FROM THE NORTH.

RADIATIONAL FOG POTENTIAL...
SLIGHT CHANCE OF PATCHY FOG FORMATION TONIGHT. THE LIMITING FACTORS
WITH FOG FORMATION TONIGHT ARE DEWPOINT DEPRESSIONS OF AROUND 6 DEGREES
AND THE WIND. THE WIND IS FORECAST TO DECREASE OVERNIGHT TO ABOUT 3-5MPH
BUT NOT QUITE CALM.

CLOUDS...
AREA IS ON THE EDGE OF THE LOW TO MID LEVEL CLOUDS THIS MORNING. ALTHOUGH
THE TREND IS FOR A DECREASE IN CLOUD COVERAGE TODAY...GUIDANCE IS TRYING
TO SHOW AN INCREASE IN THE 1-4PM RANGE /WITH THE HEATING OF THE DAY/
AND THIS COULD IMPACT HIGH TEMPERATURES TODAY. IF THESE CLOUDS DID
DEVELOP...THEY ARE FORECAST TO BE AROUND 4KFT. LOW CONFIDENCE ON THE
CLOUD FORECAST.
