FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT SAT OCT 10 2026
DISCUSSION
WETTING RAINS ASSOCIATED WITH THE REMNANTS OF HURRICANE ISAIAS
WILL CONTINUE ACROSS NORTHERN MISSISSIPPI AND WEST TENNESSEE
THROUGH EARLY SUNDAY MORNING. MINIMUM RELATIVE HUMIDITY VALUES
WILL REMAIN ABOVE 40% THROUGH THIS AFTERNOON WHILE ISAIAS'
MOISTURE REMAINS, BUT 20-FOOT WINDS COULD APPROACH 20 MILES PER
HOUR THROUGH SATURDAY EVENING. MOISTURE WILL DECREASE SUNDAY AND
INTO NEXT WEEK WITH A STEADY DROP IN RELATIVE HUMIDITY. BY MONDAY
AFTERNOON, PORTIONS OF THE REGION ARE FORECAST TO SEE MINIMUM
RELATIVE HUMIDITY VALUES BELOW 30 PERCENT, PARTICULARLY IN AREAS
THAT DO NOT SEE RAINFALL SUCH AS EASTERN ARKANSAS AND THE
MISSOURI BOOTHEEL LEADING TO THE POTENTIAL FOR ELEVATED FIRE
DANGER. HOWEVER, 20-FOOT WINDS BY THIS POINT WILL BE LIGHT,
MITIGATING HIGHER FIRE DANGER. SOUTHERLIES WILL RETURN TUESDAY,
LEADING TO MINIMUM RELATIVE HUMIDITY VALUES CLIMBING BACK ABOVE
40% THROUGHOUT THE MAJORITY OF THE REGION THROUGH THE END OF THE
FORECAST PERIOD.
