.DISCUSSION...
SHOWERS HAVE EXITED THE FIRE AREA AS OF EARLY THIS AFTERNOON...BUT
THE MOISTURE THEY LEFT BEHIND WILL LIKELY ALLOW ISOLATED SHOWERS
TO REDEVELOP WITH A SLIGHT CHANCE OF THUNDERSTORMS BY LATE AFTERNOON
AND CONTINUE INTO THIS EVENING. ANY ACTIVITY THAT DOES DEVELOP WILL
LIKELY DIMINISH BY LATE EVENING DUE TO THE LOSS OF DAYTIME HEATING.
THE LOW LEVEL MOISTURE FROM THE SHOWERS WILL ALSO ALLOW FOR GOOD
OVERNIGHT RELATIVE HUMIDITY RECOVERY. AN UPPER LEVEL RIDGE OF HIGH
PRESSURE WILL ALSO BUILD INTO THE AREA OVERNIGHT AND INTO SUNDAY
FOR MOSTLY CLEAR SKIES DRY CONDITIONS. TEMPERATURES WILL REMAIN
NEAR NORMAL WITH HUMIDITY REMAINING ABOVE 30 PERCENT. WINDS WILL
SHIFT MORE NORTHWESTERLY THIS AFTERNOON AS SURFACE HIGH PRESSURE
MOVES INTO THE AREA...THEN THEY WILL DECREASE AND BECOME MORE
EASTERLY BY SUNDAY MORNING.  COULSTON
