FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT WED OCT 21 2026
DISCUSSION
ELEVATED FIRE WEATHER CONDITIONS WILL CONTINUE AGAIN ON THURSDAY.
LOW SURFACE MOISTURE WILL LEAD TO MINIMUM RELATIVE HUMIDITY
VALUES DROPPING BELOW 30% ACROSS THE ENTIRE REGION. 10-HOUR FUELS
ARE EXPECTED TO REMAIN AT OR AROUND 10 PERCENT FUEL MOISTURE.
LIGHT 20-FOOT WINDS, LIKELY PEAKING AT ONLY 10 MPH THROUGHOUT THE
AFTERNOON, WILL PRECLUDE THE NEED FOR RED FLAG WARNINGS. SIMILAR
CONDITIONS WILL CONTINUE THROUGH THE REMAINDER OF THE PERIOD,
LIKELY NECESSITATING ADDITIONAL RANGELAND FIRE DANGER STATEMENTS
THROUGH THIS WEEK.
