FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT MON AUG 17 2026
DISCUSSION
FIRE DANGER IS EXPECTED TO REMAIN LOW THROUGH THE PERIOD DUE TO
LIGHT 20 FT WINDS, ALTHOUGH MINIMUM RELATIVE HUMIDITY VALUES MAY
DROP BELOW 40% IN SOME AREAS. ISOLATED SHOWERS ARE EXPECTED
ACROSS NORTHERN MISSISSIPPI THIS AFTERNOON ALONG A WEAK FRONT,
WHICH WILL SHIFT WINDS TO A MORE NORTHWESTERLY DIRECTION AFTER
PASSAGE. FOG POTENTIAL REMAINS LOW DUE TO DRY SOILS.
