FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 AM CDT MON AUG 31 2026
DISCUSSION
A PERSISTENT UPPER LEVEL RIDGE OF HIGH PRESSURE WILL KEEP HIGH
HEAT AND INCREASING HUMIDITY OVER THE MID-SOUTH THIS WEEK. AIR
TEMPERATURES WILL APPROACH UPPER 90S AND 100 DEGREE MARK EACH
DAY, HOWEVER, MINIMUM RELATIVE HUMIDITY VALUES ARE EXPECTED TO
REMAIN ABOVE 35 PERCENT ALL WEEK LONG. 20-FOOT WINDS ARE EXPECTED
TO REMAIN LESS THAN 10 MPH REMAINING BELOW CRITICAL FIRE WEATHER
THRESHOLDS. HOWEVER, 10 AND 100 HOUR FUELS WILL CONTINUE TO DRY
AND CURE. THIS PROLONGED AND HOT AND DRY PERIOD WITH NO
APPRECIABLE RAINFALL MAY TRIGGER ELEVATED FIRE WEATHER DANGER
THIS
WEEK. THE THREAT OF FOG EACH MORNING WILL REMAIN LOW AND
ISOLATED, CONFINED MAINLY TO NEARBY LOCALIZED RIVER BASINS.
