FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT MON OCT 12 2026
DISCUSSION
DRY AIR HAS RETURNED TO THE MID-SOUTH WITH MINIMUM RELATIVE
HUMIDITY VALUES IN THE MIDDLE TO LOW 30S MONDAY. 20-FOOT WINDS
WILL BE SLIGHTLY ELEVATED ACROSS NORTHEASTERN ARKANSAS AND THE
MISSOURI BOOTHEEL, POTENTIALLY LEADING TO ELEVATED FIRE WEATHER
CONDITIONS THROUGH MONDAY AFTERNOON. SOUTHERLY FLOW WILL BRING
MOISTURE BACK INTO THE REGION THROUGH THE END OF THE WEEK WITH
MINIMUM RELATIVE HUMIDITY VALUES BACK ABOVE 40 PERCENT FOR MOST
AREAS THROUGH WEDNESDAY. A DROP IN HUMIDITY THROUGH THE END OF
THE WEEK WILL SEE THE RETURN OF RELATIVE HUMIDITY BELOW
40 PERCENT. A FRONT WILL PASS THROUGH THE REGION FRIDAY,
DECREASING TEMPERATURES AND HUMIDITY INTO NEXT WEEKEND. ELEVATED
20-FOOT WINDS BEHIND THE FRONT COULD LEAD TO AN INCREASE IN FIRE
DANGER ESPECIALLY AS 10-HOUR FUELS CONTINUE TO DRY THIS WEEK FOR
MOST OF THE MID-SOUTH.
