DISCUSSION
 
 
IN TERMS OF MIXING HEIGHTS AND TRANSPORT WINDS, TODAY WILL HAVE  
FAVORABLE BURNING CONDITIONS. THE MAIN ISSUE FOR YOUR LOCATION  
TODAY WILL BE THE POTENTIAL FOR SHOWERS AND THUNDERSTORMS THIS  
AFTERNOON. STARTING AROUND 3 PM, THERE WILL BE A CHANCE FOR POP UP  
SHOWERS AND THUNDERSTORMS THAT MAY CONTINUE THROUGH 6 PM.  
AFTERWARDS, EXPECT COVERAGE OF SHOWERS AND STORMS TO INCREASE AS A  
LINE APPROACHES FROM THE WEST. FOR THE NEXT 24 HOURS, I WOULD  
RECOMMEND YOU TRY TO FINISH BURNING BY THAT 3-6 PM WINDOW BEFORE  
THE CONVECTION BECOMES MORE WIDESPREAD.
