DISCUSSION  
 
THE MAIN ISSUE TODAY WILL BE THE GUSTY WINDS WHICH LOOK LIKELY TO  
GUST BETWEEN 25 AND 30 MPH THIS AFTERNOON. THIS LOOKS MOST LIKELY  
BETWEEN THE SCHEDULED INITIATION TIME AND 4 TO 5 THIS AFTERNOON.  
WINDS LOOK TO DIMINISH WITH THE LOSS OF DAYTIME HEATING/ MIXING.  
HOWEVER A STRONG COLD FRONT WILL MOVE THROUGH THE AREA THIS  
EVENING, SHIFTING WINDS TO THE NW AND INCREASING GUSTS TO AROUND  
30 MPH. THERE IS ALSO A GOOD CHANCE (60-80%) FOR WINDS TO GUST IN  
EXCESS OF 35 MPH BEHIND THE FRONT THIS EVENING.
