FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT TUE MAY 12 2026
DISCUSSION
MARGINAL FIRE DANGER CONCERNS WILL ARISE TUESDAY AFTERNOON
THROUGH AT LEAST THURSDAY AFTERNOON, WITH MINRH VALUES FALLING
BELOW 40 PERCENT. MINRH VALUES WILL LIKELY DIP BELOW 30% FOR ALL
OF THE MID-SOUTH TUESDAY AND THURSDAY AFTERNOONS. ON WEDNESDAY
AFTERNOON, SOME LOCATIONS ACROSS EASTERN AR, THE MO BOOTHEEL, AND
WEST TN COULD SEE VALUES FALL BELOW 25 PERCENT. 10-HR DEAD FUEL
MOISTURE WILL BE AROUND TO JUST BELOW 10 PERCENT THROUGH THIS
PERIOD, BUT RECENT RAINFALL AND LIGHT WINDS TODAY WILL SUPERSEDE
THE NEED FOR ANY PRODUCTS. ON WEDNESDAY, AN RFD MAY BE NEEDED IF
THESE TRENDS CONTINUE GIVEN THE LOW RH VALUES AND RELATIVELY LOW
FUEL MOISTURE CONTENT.
