DISCUSSION...
VERY LOW HUMIDITY EXPECTED AGAIN TODAY WITH LIGHTER WINDS THAN
OBSERVED THURSDAY. THUS...WINDS WILL BE VARIABLE DUE TO TERRAIN
INFLUENCES. HUMIDITY RECOVERY TONIGHT WILL BE POOR FOR MOST OF THE
OVERNIGHT...HOWEVER...A VIGOROUS BACK DOOR FRONT IS EXPECTED TO
INFLUENCE THE FIRE AREA LATE TONIGHT AND PROVIDE AN INCREASE IN
HUMIDITY. EXACT TIMING OF FRONT ARRIVAL IS SKETCHY...BUT THINKING
SOMETIME AROUND SUNRISE OR A LITTLE BEFORE. MUCH HIGHER HUMIDITY
EXPECTED ON SATURDAY WITH AFTERNOON SHOWERS AND THUNDERSTORMS. DRY
AIR TO THE WEST AND MOIST AIR TO THE EAST WILL MEET OVER THE FIRE
AREA...SO HUMIDITIY COULD VARY CONSIDERABLY AND THERE WILL BE A
SLIGHT CHANCE FOR WET/DRY THUNDERSTORMS AROUND THE FIRE AREA ON
SATURDAY.
