DISCUSSION
 
 
FIRE WEATHER CONDITIONS TODAY WILL BE VERY SIMILAR TO YESTERDAY ALBEIT  
THE WINDS ARE NOT EXPECTED TO BE QUITE AS GUSTY THIS AFTERNOON. MIXING  
HEIGHTS TODAY WILL BE NEAR 9000 FEET WITH SUFFICIENT NORTHWESTERLY TRANSPORT  
WINDS AND FAVORABLE DISPERSION INDICES FOR A PRESCRIBED BURN. RELATIVE HUMIDITIES  
WILL BE IN THE LOW 40% RANGE AND SINCE SOILS AND VEGETATION REMAIN VERY DRY, FUELS  
SHOULD SPARK QUICKLY AND FLAMES MAY EASILY SPREAD. ALSO, THERE IS AN ISOLATED CHANCE  
FOR AN AFTERNOON THUNDERSTORM AT THE BURN SITE IN THE TALLADEGA NATIONAL FOREST AS A  
WEAK COLD FRONT APPROACHES THE AREA. WE DO NOT EXPECT WIDESPREAD RAIN COVERAGE SINCE  
THE AIR REMAINS UNFAVORABLY DRY, BUT THERE REMAINS THE LOW CHANCE FOR AN ISOLATED  
THUNDERSTORM TO DEVELOP ALONG THE COLD FRONT AND NEAR THE BURN SITE THIS AFTERNOON.
