FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT SUN OCT 11 2026
DISCUSSION
DRY AIR HAS RETURNED TO THE REGION BEHIND ISAIAS' DEPARTURE.
MINIMUM RELATIVE HUMIDITY VALUES WILL THEREFORE DROP THROUGH
MONDAY WITH VALUES BELOW 40 PERCENT STARTING TODAY, DROPPING TO
AROUND OR BELOW 30 PERCENT MONDAY FOR MOST AREAS. HOWEVER, LIGHT
20-FOOT WINDS AND LOW COVERAGE OF RELATIVE HUMIDITY VALUES BELOW
30 PERCENT WILL LEAD TO RELATIVELY LOW FIRE DANGER. SOUTHERLY
FLOW WILL RETURN TUESDAY, BRINGING HIGHER MOISTURE BACK INTO THE
REGION AND INCREASING RELATIVE HUMIDITY VALUES AROUND OR ABOVE
40 PERCENT. THIS PATTERN WILL REMAIN THROUGH THE END OF THE WEEK
BEFORE A COLD FRONT PASSES THROUGH THE MID-SOUTH FRIDAY, LEADING
TO COOLER, DRIER WEATHER NEXT WEEKEND.
