NATIONAL WEATHER SERVICE MEMPHIS TN
330 AM CDT SUN OCT 18 2026

ELEVATED FIRE WEATHER CONDITIONS ARE EXPECTED TO PERSIST THROUGH
THE FORECAST PERIOD. CURRENT RELATIVE HUMIDITY FORECASTS CALL FOR

FALLING BENEATH 20 PERCENT BY THE MIDDLE OF THE WEEK. WITH A LACK
OF RAINFALL OVER THE PAST MONTH, FUELS HAVE BEGUN TO DRY OUT,
LEADING TO 10-HOUR FUELS FALLING TO AROUND 10 PERCENT.
FORTUNATELY, 20-FOOT WINDS WILL REMAIN LIGHT AS HIGH PRESSURE
SITS OVER THE MID-SOUTH. RANGELAND FIRE DANGER STATEMENTS ARE
EXPECTED TO BE NEEDED THROUGH THIS WEEK.
