SPOT FORECAST FOR LEOLA...USFS
NATIONAL WEATHER SERVICE HUNTSVILLE AL
643 AM CST FRI JAN 30 2015

FORECAST IS BASED ON IGNITION TIME OF 0900 CST ON JANUARY 30.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...
DRY AND COOL CONDITIONS ARE EXPECTED TODAY WITH CLOUDS RECEDING BY
NOON OVER THE BURN SITE. HOWEVER, NORTHERLY WINDS OF 10 MPH GUSTING
TO 15 MPH ARE EXPECTED UNTIL AROUND 1PM. TEMPERATURES ARE NOT
FORECAST TO RISE MUCH, WHICH SHOULD KEEP RELATIVE HUMIDITY VALUES
BETWEEN 38-40 PERCENT TODAY. MIXING HEIGHTS SHOULD REMAIN FAIRLY
CONSTANT TODAY NEAR 2600 FEET. WITH THESE MIXING HEIGHTS AND THE
GUSTY WINDS, DISPERSION SHOULD BE GENERALLY GOOD OVER THE BURN SITE.

THEN, WINDS SHOULD RELAX OVERNIGHT ALMOST TO CALM WITH CLOUDS
RETURNING. BY SATURDAY, WINDS WILL BE CALM FOR MOST OF THE DAY OVER
THE BURN SITE WHICH WILL TRANSLATE TO POOR DISPERSION. THE PRIMARY
CONCERN THOUGH IS RELATIVE HUMIDITY VALUES MAY DROP LOWER THAN
CURRENTLY FORECAST...CLOSE TO 25% BY 2PM-4PM ON SATURDAY.
