FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT SAT AUG 22 2026
DISCUSSION
A WEAK COLD FRONT HAS CLEARED THE REGION AND DROPPED RELATIVE
HUMIDITY VALUES INTO THE LOWER 40 PERCENT RANGE ACROSS AREAS
ALONG AND WEST OF THE MISSISSIPPI RIVER, WITH THIS DRIER AIR
FILTERING ACROSS THE MAJORITY OF THE MID-SOUTH. HOWEVER, LIGHT
SURFACE WINDS, DAILY RAIN CHANCES, AND ADEQUATE OVERALL MOISTURE
WILL KEEP CRITICAL FIRE WEATHER CONCERNS SAFELY AT BAY. THE
COMBINATION OF LIGHT OVERNIGHT WINDS AND CLEAR SKIES WILL ALSO
CREATE A POTENTIAL FOR PATCHY FOG DURING THE EARLY MORNING HOURS,
PARTICULARLY ALONG LOW-LYING RIVER BASINS.
