330 AM CDT SAT AUG 22 2026
DISCUSSION
A FEW AREAS OF FOG CANNOT BE RULED OUT NEAR THE TENNESSEE RIVER
TONIGHT, BUT ANY REDUCTION IN VISIBILITY SHOULD QUICKLY RESOLVE
AFTER SUNRISE. OTHERWISE, RELATIVE HUMIDITY VALUES AROUND
40 PERCENT WILL BE IN PLACE THROUGH SUNDAY. FIRE WEATHER CONCERNS
WILL REMAIN LOW DUE TO LIGHT 20 FT WINDS AND WETTING RAIN CHANCES
RETURNING NEXT WEEK.
