FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT SUN OCT 4 2026
DISCUSSION
MINIMUM RELATIVE HUMIDITY VALUES WILL REMAIN ABOVE 40 PERCENT FOR
THE MAJORITY OF THE REGION SUNDAY, BUT ANOTHER FRONTAL PASSAGE
SUNDAY NIGHT WILL BRING LOWER HUMIDITY INTO THE MID-SOUTH.
MINIMUM RELATIVE HUMIDITY VALUES WILL GENERALLY SIT BETWEEN
30 AND 40 PERCENT MONDAY AND TUESDAY. WARMER WEATHER WILL ENTER
THE FORECAST BY WEDNESDAY, LEADING TO A SHARP DECREASE IN
RELATIVE HUMIDITY VALUES THROUGH THE END OF THE WEEK, DROPPING TO
30 PERCENT OR BELOW. THIS WILL MARK THE RETURN OF ELEVATED FIRE
DANGER. LIGHT 20-FOOT WINDS AND RECENT WETTING RAINS ARE EXPECTED
TO CURTAIL A HIGHER THREAT OF FIRE DANGER.
