DISCUSSION
MINIMUM RELATIVE HUMIDITY VALUES WILL CONTINUE TO FALL BELOW 40%
ACROSS THE MAJORITY OF THE REGION THROUGH THIS WEEKEND WITH
LOW (LESS THAN 20 PERCENT) CHANCES FOR AFTERNOON SHOWERS.
ADDITIONALLY, A D3 (EXTREME) DROUGHT HAS BEEN PLACED FOR PORTIONS
OF NORTHWEST TENNESSEE, THE MISSOURI BOOTHEEL, AND EASTERN
ARKANSAS. THESE TWO FACTORS WILL KEEP FIRE DANGERS ELEVATED
THROUGH THE PERIOD. LIGHT 20 FT WINDS WILL PREVENT MORE
SIGNIFICANT FIRE CONCERNS.
