FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 AM CDT WED OCT 21 2026
DISCUSSION
ELEVATED FIRE WEATHER CONDITIONS WILL CONTINUE WEDNESDAY WITH
ANOTHER RANGELAND FIRE DANGER STATEMENT ISSUED FOR THE AFTERNOON
AND EARLY EVENING HOURS. 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.
