FIRE WEATHER PLANNING FORECAST FOR CENTRAL KENTUCKY AND SOUTHERN INDIANA
NATIONAL WEATHER SERVICE LOUISVILLE KY
321 PM EDT TUE OCT 20 2026
DISCUSSION
OUR PROLONGED PERIOD OF DRY WEATHER CONTINUES THROUGH THE
WEEKEND, LIKELY THROUGH EARLY NEXT WEEK. ALTHOUGH OVERNIGHT RH VALUES
WILL SEE GOOD RECOVERY IN THE 90-100% RANGE, CONTINUED SUNNY DAYS WITH
AFTERNOON HIGHS ABOVE NORMAL AND MINIMUM RH VALUES IN THE 30% RANGE WILL
BEGIN TO LEAD TO MORE RECEPTIVE FUELS. THE OVERALL LIMITING FACTOR TO
BETTER BURNING CONDITIONS WILL LIKELY BE LIGHT SURFACE AND TRANSPORT
WINDS, HURTING OVERALL DISPERSION.
