FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 AM CDT SAT SEP 19 2026
DISCUSSION
A STRONG UPPER LEVEL RIDGE CENTERED OVER THE LOWER MISSISSIPPI
VALLEY WILL MAINTAIN NEAR-RECORD LATE-SEPTEMBER HEAT AND LARGELY
RAIN-FREE CONDITIONS. WHILE MINIMUM RELATIVE HUMIDITY (RH) VALUES
ARE EXPECTED TO HOVER IN THE 20-30% RANGE, LIGHT 20-FOOT SURFACE
WINDS UNDER 10 KNOTS WILL PREVENT CRITICAL FIRE WEATHER
CONDITIONS. HOWEVER, 10-HOUR FUELS WILL CONTINUE DRYING DOWN
TOWARD 10% UNDER INTENSE DAYTIME HEATING. FOG POTENTIAL REMAINS
LOW ACROSS THE REGION, RESTRICTED MAINLY TO BRIEF, PATCHY MORNING
FOG ALONG LOW-LYING RIVER BASINS.
