...RED FLAG WARNING IN EFFECT WEDNESDAY AFTERNOON AND EARLY EVENING...

.DISCUSSION...SURFACE HIGH PRESSURE WILL REMAIN IN CONTROL THROUGH
THE MID WEEK PERIOD KEEPING OUR WEATHER DRY. ANOTHER DAY OF
CRITICALLY LOW RELATIVE HUMIDITY IS EXPECTED FOR WEDNESDAY. WINDS
WILL BE FROM THE EAST AND THEN EAST SOUTHEAST THROUGH MUCH OF THE
DAY ON WEDNESDAY WHICH SHOULD HELP BRING A SMALL INCREASE IN
LOW LEVEL MOISTURE OFF APALACHEE BAY. HOWEVER...THIS INCREASE IN
MOISTURE WILL BE INITIALLY SMALL WHICH SHOULD STILL ALLOW FOR
RELATIVE HUMIDITY VALUES TO FALL BELOW 35 PERCENT. RELATIVE
HUMIDITY VALUES AWAY FROM THE COAST WILL FALL INTO THE MIDDLE
20S WEDNESDAY AFTERNOON. AT THIS TIME THESE LOWER VALUES ARE
NOT ANTICIPATED TO REACH THE BURN LOCATION DUE TO THE ONSHORE
FLOW...HOWEVER IF THE EXPECTED TURNING OF THE WINDS IS SLOWER
TO OCCUR THAN RELATIVE HUMIDITY VALUES COULD BRIEFLY REACH THE
UPPER 20S DURING THE EARLY AFTERNOON.
