DISCUSSION
 
 
DRY WEATHER WILL PREVAIL TODAY WITH GRADUALLY DECREASING CLOUD COVER  
INTO THE AFTERNOON, AND ANY PRECIPITATION REMAINING TO THE SOUTHEAST  
OF THE PROJECT SITE. BREEZY WINDS WILL CONTINUE THROUGH THE DAY, WITH  
HIGH CONFIDENCE IN THE PREVAILING WIND DIRECTION BEING ROUGHLY OUT OF  
THE NORTH. SUSTAINED SPEEDS SHOULD REMAIN BELOW 14 MPH, WITH PEAK  
20-FT GUSTS OF AROUND 25 MPH POSSIBLE NEAR MIDDAY.  
 
TODAY'S STRONGER WINDS WILL ENSURE SEVERAL HOURS OF GOOD OR BETTER  
SMOKE DISPERSAL LATE MORNING THROUGH MID AFTERNOON.  
 
ON FRIDAY, EXPECT DRY AND MILDER CONDITIONS WITH PARTLY CLOUDY SKIES.  
WINDS WILL BE WEAKER AND LIKELY LEAD TO FAIRLY PROLONGED POOR SMOKE  
DISPERSAL, ALSO A BRIEF 1-2 HOUR WINDOW OF FAIR CONDITIONS ISN'T OUT  
OF THE QUESTION DURING THE AFTERNOON.
