NATIONAL WEATHER SERVICE MEMPHIS TN
330 AM CDT SAT SEP 12 2026
DISCUSSION
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO
CONTINUE PRODUCING WETTING RAINS THROUGH SATURDAY AFTERNOON,
PRIMARILY ACROSS PORTIONS OF WEST TN AND NORTHERN MS. RAINS FROM
THE PAST 24 HOURS WILL KEEP MINIMUM RELATIVE HUMIDITY VALUES
ABOVE 40% THROUGHOUT THE REGION THROUGH SUNDAY AFTERNOON, WHICH
ALONGSIDE WEAK 20 FOOT WINDS, WILL KEEP FIRE DANGER AT A MINIMUM.
HOT AND PRECIPITATION-FREE CONDITIONS WILL ARRIVE BY SUNDAY AND
ARE EXPECTED TO REMAIN THROUGH THE END OF THE FORECAST PERIOD.
INTO EARLY NEXT WEEK, MINIMUM RELATIVE HUMIDITY VALUES WILL BEGIN
TO DROP BELOW 40% AS THE AREA DRIES OUT, BUT A CONTINUATION OF
LIGHT 20 FOOT WINDS AND INCREASED SOIL MOISTURE FROM RECENT RAINS
WILL CONTINUE TO KEEP FIRE DANGER AT A MINIMUM.
