FORECAST IS BASED ON IGNITION TIME OF 1000 EDT ON MARCH 19.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.
DISCUSSION
DRY WEATHER CONDITIONS WILL REMAIN ACROSS THE BURN SITE FOR
THURSDAY AS A SURFACE HIGH PRESSURE AXIS EXTENDS ACROSS THE AREA.
THIS HIGH PRESSURE WILL HELP TO KEEP WINDS ON THE LIGHTER SIDE
THROUGH MUCH OF THE DAY. PRIOR TO THE INVERSION BREAKING, WINDS
WILL BE NEARLY CALM, THEN BETWEEN 10-11 AM AS THE INVERSION BREAKS
LIGHT WINDS OUT OF THE NORTH WILL BEGIN, ALTHOUGH WITH THE CLOSENESS
OF THE LAKE, THE DIRECTION COULD REMAIN QUITE VARIABLE THROUGH THE
DAY. ANY SUSTAINED SURFACE WIND SPEEDS GENERALLY ONLY AROUND 5
MPH AT BEST. DEWPOINTS TONIGHT WILL REBOUND BACK INTO THE MID TO
UPPER 20S BY SUNRISE, AND WE DO EXPECT A CONTINUED INCREASE IN
LOW-LEVEL MOISTURE THROUGH THE DAY. HOWEVER WITH THE DAYTIME
TEMPERATURES FINALLY MODERATING SOMEWHAT BACK INTO THE MIDDLE
60S BY THE AFTERNOON, WE STILL EXPECT TO SEE THE MINRH VALUES
DROPPING TO BETWEEN 30-35 PERCENT. SKIES WILL BE MOSTLY SUNNY,
WITH POSSIBLY SOME THIN CIRRUS PASSING ACROSS THE REGION THROUGH
THE AFTERNOON HOURS. FINALLY, ALTHOUGH FOG IS NOT EXPECTED
THURSDAY MORNING, VERY SHALLOW GROUND FOG CAN NOT BE RULED CLOSE
TO THE LAKE.
