SPOT FORECAST FOR LONG LANE FALL BURN...US FOREST SERVICE
NATIONAL WEATHER SERVICE COLUMBIA SC
303 AM EDT WED OCT 28 2026
FORECAST IS BASED ON IGNITION TIME OF 0900 EDT ON OCTOBER 28.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.
.DISCUSSION..DAY MAY START OFF WITH SOME PATCHY GROUND FOG, BUT
THIS SHOULD BE JUST ABOUT GONE BY IGNITION TIME. ANOTHER DRY DAY
IS ON TAP ACROSS THE BURN LOCATION AS HIGH PRESSURE CONTINUES TO
BE IN CONTROL ACROSS THE REGION. THE MORNING INVERSION IS EXPECTED
TO BEGIN BREAKING TOWARDS 10 AM, WHICH WILL BRING WINDS FROM
NORTHEASTERLY AND LIGHT, TO MORE NORTHEASTERLY BETWEEN 7-12 MPH.
IN ADDITION, GUSTS WILL BECOME PROBABLE THROUGH THE AFTERNOON,
REACHING BETWEEN 15 AND 20 MPH AT TIMES. THERE WILL BE AN INCREASE
IN LOW-LEVEL MOISTURE COMPARED TO PREVIOUS DAYS, AND THIS WILL
CAUSE MIN RH READINGS THIS AFTERNOON TO ONLY DROP DOWN TO
BETWEEN 50-55 PERCENT BETWEEN 3-5PM, ALTHOUGH CAN NOT RULE OUT
PERIODS WHERE IT WILL BE LOWER THAN THAT DEPENDING ON THE AMOUNT OF
MIXING THAT OCCURS. SKIES WILL START OFF MOSTLY CLEAR, THEN
THERE SHOULD BE AN INCREASE IN SOME THIN CIRRUS AS THE DAY
PROGRESSES.
AS FOR DISPERSION ISSUES OVERNIGHT, MAINLY PATCHY FOG FORMATION
POSSIBLE AGAIN THROUGH THE NIGHT. WINDS WILL REMAIN LIGHT AND
OUT OF THE NORTHEAST AFTER SUNSET ONCE LOW-LEVELS DECOUPLE. THE
INVERSION AND LIGHT WINDS COULD CAUSE SOME DISPERSION ISSUES LATE
TONIGHT.
