FORECAST IS BASED ON IGNITION TIME OF 1100 CDT ON OCTOBER 08.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...
SURFACE HIGH CURRENTLY LOCATED OVER THE SOUTHERN GREAT LAKES
REGION AND AN UPPER LEVEL RIDGE AXIS BUILDING INTO THE NORTHERN
PLAINS WILL CREATE DRY AND WARM CONDITIONS TODAY. TEMPERATURES
WILL WARM INTO THE UPPER 70S AND MINIMUM RH VALUES WILL DROP INTO
THE LOWER TO MID 30 PERCENT RANGE OVER THE PRESCRIBED BURN
LOCATION THIS AFTERNOON. THE OTHER CONCERN WILL BE THE POOR SMOKE
DISPERSAL ACROSS THE AREA WITH TRANSPORT WINDS VERY LIGHT...5 MPH
OR LESS...AND MIXING HEIGHTS RELATIVELY SHALLOW...ONLY UP TO 2000
TO 3000 FT. THESE CONDITIONS WILL ONLY ALLOW FOR SMOKE DISPERSAL
VALUES AROUND 5000 AT NOON...10000 AT 2 PM...AND 12000 AT 4 PM.
THE CURRENT FORECAST KEEPS SMOKE DISPERSAL IN THE POOR CATEGORY
THROUGH TODAY.

TOMORROW CONDITIONS REMAIN RELATIVELY WARM...BUT HUMIDITY VALUES
INCREASE SLIGHTLY...TRANSPORT WINDS INCREASE FROM THE SOUTHEAST
AND SMOKE DISPERSAL VALUES INCREASE OVER 30000...INTO THE GOOD
CATEGORY. A NARROW RIDGE PERSISTS IN ADVANCE OF AN APPROACHING LOW
PRESSURE SYSTEM MOVING INTO THE CENTRAL U.S.
