FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT WED SEP 23 2026
DISCUSSION
WETTING RAINS ARE UNLIKELY THROUGH THE REST OF THE WEEK, BUT
COOLER TEMPERATURES WILL KEEP MINIMUM RELATIVE HUMIDITY VALUES
ABOVE 40% FOR THE MAJORITY OF THE REGION. HIGHER RELATIVE
HUMIDITY VALUES IN CONJUNCTION WITH INCREASING 10 HOUR FUEL
HUMIDITY LEVELS AND LIGHT 20 FT WINDS ARE EXPECTED TO KEEP FIRE
DANGER LOW THROUGH THE FORECAST. WETTING RAINS MAY RETURN TO
PORTIONS OF EASTERN ARKANSAS, THE MISSOURI BOOTHEEL, AND WEST
TENNESSEE SUNDAY, WHICH WOULD PROVIDE A FURTHER DECREASE IN FIRE
DANGER.
