FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT MON AUG 31 2026
DISCUSSION
A PERSISTENT UPPER-LEVEL RIDGE WILL DOMINATE THE MID-SOUTH OVER
THE NEXT THREE DAYS, BRINGING OPPRESSIVE HEAT AND PROLONGED DRY
CONDITIONS ACROSS THE REGION. WHILE OVERALL FIRE WEATHER THREAT
LEVELS REMAIN LOW TO SLIGHTLY ELEVATED DUE TO LIGHT WINDS AND
MINIMUM RELATIVE HUMIDITY (RH) VALUES STAYING AT OR ABOVE 30%,
THE LACK OF RAINFALL WILL CONTINUE TO DRY OUT 10-HOUR AND 100-
HOUR SURFACE FUELS. FOG POTENTIAL WILL BE MINIMAL ACROSS MOST OF
THE REGION, RESTRICTED MAINLY TO LOCALIZED RIVER VALLEYS.
