TODAY WILL BE WARMER, INTO THE LOW 60S ALONG THE TENNESSEE RIVER,
AND THE 50S ON THE CUMBERLAND PLATEAU.

ISSUED AT 1137 AM CDT WED MAR 18 2026
HIGH PRESSURE WILL BUILD IN TO OUR SOUTH INTO THE WEEKEND, LETTING
OUR TEMPERATURES REBOUND NICELY INTO THE 70S AND LOW 80S FOR HIGHS.
THIS DRY PERIOD WILL BE BRIEF FOR PARTS OF THE AREA ON THE
CUMBERLAND PLATEAU, HOWEVER, AS SOME LOW END RAIN CHANCES (<20%)
ENTER WITH A COLD FRONT ON MONDAY MORNING. QPF WITH THIS DOES NOT
LOOK HIGH CURRENTLY, BUT THERE IS STILL QUITE A BIT OF DIVERGENCE IN
THE GUIDANCE SO A BIT TOO SOON TO SAY MUCH MORE ON THIS OPPORTUNITY
FOR PRECIPITATION. AFTER THE COLD FRONT ON MONDAY, HIGHS WILL RETURN
TO THE 60S AND 70S THROUGH THE REMAINDER OF THE FORECAST PERIOD WITH
SURFACE HIGH PRESSURE LOOKING TO BUILD IN BEHIND THE FRONT.
