SERVICE.
DISCUSSION
ASIDE FROM A FEW PASSING HIGH CLOUDS AND FAIR-WEATHER CUMULUS,
MOSTLY SUNNY SKIES WILL EXIST IN THE VICINITY OF THE PRESCRIBED
BURN SITE TODAY (ALONG WITH DRY CONDITIONS). DUE TO WARMER
AFTERNOON TEMPERATURES (IN THE UPPER 70S) A GRADUAL INCREASE IN
DEWPOINTS WILL NOT HAVE A SIGNIFICANT IMPACT ON MINRH VALUES, AS
THESE SHOULD DROP INTO INTO THE 35-40% RANGE BY MID-AFTERNOON.
SMOKE PLUME DISPERSION WILL BE VERY GOOD TO THE NORTHEAST, AS A
RESULT OF SOUTHWESTERLY TRANSPORT WINDS STEADILY INCREASING TO
AROUND 20 MPH AND A HIGH AFTERNOON MIXING HEIGHT AROUND 5300 FT.
OVERNIGHT, WE EXPECT PARTLY CLOUDY SKIES AND DRY CONDITIONS, WITH
SURFACE WINDS REMAINING FROM THE SOUTHWEST (BUT DIMINISHING
SHORTLY AFTER SUNSET). PATCHY FOG WILL BE POSSIBLE ACROSS MUCH OF
THE REGION EARLY SATURDAY MORNING.
