FIRE WEATHER PLANNING FORECAST FOR DEEP SOUTH TEXAS  
NATIONAL WEATHER SERVICE BROWNSVILLE TX  
518 AM CDT SAT SEP 23 2017  
   
DISCUSSION
 
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS  
WILL BE POSSIBLE OVER THE NEXT SEVERAL DAYS ACROSS DEEP SOUTH  
TEXAS DUE TO THE COMBINATION OF DAYTIME HEATING AND INCREASING  
TROPICAL MOISTURE. A COLD FRONT WILL THEN APPROACH THE REGION  
AROUND MIDWEEK NEXT WEEK WHICH WILL HELP INCREASE THE RAIN  
CHANCES. OTHERWISE THE 20 FOOT WINDS AND MINIMUM RELATIVE HUMIDITY  
VALUES WILL PRECLUDE ANY FIRE WEATHER CONCERNS OVER THE NEXT FEW  
DAYS. HOWEVER FUELS STILL REMAIN DRY ACROSS PORTIONS OF THE UPPER  
VALLEY AND WESTERN RANCHLANDS THROUGHOUT THE NEXT SEVERAL DAYS.
