DISCUSSION
GENERALLY VERY HOT AND DRY CONDITIONS SHOULD PREVAIL OVER THE
NEXT SEVERAL DAYS. INLAND RH VALUES ARE EXPECTED TO DROP INTO THE
30-40% RANGE, WITH VALUES ABOVE 50% NEAR THE COAST. IT IS WORTH
MENTIONING THAT FUELS ARE BECOMING DRIER DUE TO THE RECENT DRY
AND
HOT CONDITIONS. RAIN CHANCES REMAIN VERY LOW.....THOUGH WE MAY
NEED TO KEEP AN EYE OUT FOR SOME SCATTERED PRECIPITATION IN THE
PINEY WOODS REGION FRIDAY EVENING AS AN UPPER LEVEL DISTURBANCE
SAGS INTO THE AREA.
