FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 AM CDT MON APR 20 2026
DISCUSSION
FIRE WEATHER CONCERNS WILL BE ON THE RISE THROUGH TUESDAY AS
MINIMUM RELATIVE HUMIDITY VALUES DROP TO 25-30% EACH DAY. RECENT
WETTING RAINS WILL LIKELY NEGATE THE NEED FOR A RANGELAND FIRE
DANGER STATEMENT MONDAY. HOWEVER, INCREASING 20FT WINDS AND DEAD
FUEL MOISTURE NEAR 10 PERCENT WILL LIKELY NECESSITATE A NEED FOR
FIRE WEATHER PRODUCTS ON TUESDAY. INCREASED DEWPOINTS RETURN
WEDNESDAY THROUGH THE END OF THE WEEK, DECREASING FIRE WEATHER
CONCERNS.
