.DISCUSSION...
CLEARING OCCURRED OVERNIGHT BEHIND THE SYSTEM WHICH BROUGHT THE
SHOWERS TO THE AREA TUESDAY. THE CLEARING OVERNIGHT COMBINED WITH
LIGHT WINDS AND MOIST GROUND ALLOWED BY CONSIDERABLE GROUND FOG TO
FORM. IT IS EXPECTED THAT SUNSHINE ABOVE THE FOG LAYER WILL BURN
OFF THE FOG PRETTY QUICKLY...BUT IN SOME SPOTS IT COULD TAKE TIL
10 AM. WINDS ARE EXPECTED TO BECOME MORE WEST-SOUTHWEST LATE
MORNING AND EARLY AFTERNOON BUT LIKELY BECOME MORE SOUTH OR
SOUTHEAST LATE IN THE AFTERNOON AHEAD OF THE NEXT SYSTEM. SPEEDS
TODAY WILL BE LIGHT AS WELL...UNDER 10 MPH. THE LIGHT WIND SPEEDS
MAY MAKE FOR A VARIABLE WIND SITUATION AT TIMES...SO IN OTHER
WORDS WIND DIRECTION CONFIDENCE IS A BIT LOWER THAN NORMAL THROUGH
THE COURSE OF THE DAY.  AFTERNOON HIGH TEMPERATURES INTO THE MID 70S
SHOULD ALLOW FOR RELATIVE HUMIDITY VALUES TO FALL INTO THE LOW TO
MID 30 PERCENT RANGE BY LATE AFTERNOON.

THE NEXT SYSTEM IS FORECAST TO BRING INCREASING CHANCES FOR SHOWERS AND
MAYBE A THUNDERSTORM TO THE AREA OVERNIGHT TONIGHT AND THEN EXIT
THURSDAY MORNING.  RAINFALL AMOUNTS WILL BE LIGHT OVERALL...UNDER ONE
QUARTER OF AN INCH.
