SPOT FORECAST FOR C-38/41...USFS
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
345 AM EDT SUN MAR 22 2026
FORECAST IS BASED ON IGNITION TIME OF 0700 EDT ON MARCH 22.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.
DISCUSSION
GIVEN AN IGNITION TIME OF 0700 EDT, COULD SEE LOCALIZED DENSE FOG AT
OR NEAR THE BURN SITE IN THE MORNING. CONFIDENCE IS LOW, AND THIS
POSSIBILITY IS NOT REFLECTED IN THE TABULOR FORECAST BELOW. IF FOG
DEVELOPS, IT SHOULD QUICKLY SCATTER OUT BY 8-9AM.
OTHERWISE, DRY CONDITIONS TODAY WITH MINIMAL RAIN CHANCES AND STEADY
SW WIND. THE AFTERNOON WILL FEATURE FREQUENT GUSTS OF 15-20MPH. COULD
SEE AN OCCASIONAL GUST UP TO 26MPH, BUT THIS WOULD BE INFREQUENT, AND A
WORST CASE SCENARIO. RH WILL DROP INTO THE LOW 30S. THERE WOULD
APPEAR TO BE VERY LOW PROBABILITY (10% CHANCE OR LESS) OF RH DROPPING
BELOW 30%.
TRANSPORT WINDS WILL BE OUT OF THE WEST AND PROMOTE EXCELLENT
VENTILATION FOR MOST OF THE AFTERNOON.
OCCASIONAL GUSTS AS HIGH AS 20MPH WILL PERSIST OVERNIGHT. SHORTLY
AFTER NOON ON MONDAY, WINDS SHOULD TOGGLE AROUND TO THE N/NW. POTENTIAL
FOR GUSTS LOOKS A LITTLE LOWER ON MONDAY AFTERNOON, 20MPH REPRESENTING
THE UPPER BOUND.
IF YOU HAVE QUESTIONS, CONTACT THE OFFICE AND A METEOROLOGIST WILL BE
HAPPY TO ASSIST YOU.
