NATIONAL WEATHER SERVICE MORRISTOWN TN
1232 AM EST SUN DEC 21 2025
DISCUSSION
THIS AFTERNOON MAY BE EXTREMELY DRY, DEPENDING ON THE STRENGTH OF
MIXING BEHIND A DRY COLD FRONT. A FEW COOL NIGHTS, BUT PRIMARILY
DRY AND MILDER CONDITIONS WILL CONTINUE WITH A WARMING TREND
THROUGH CHRISTMAS. CHANCES FOR NEGLIGIBLE RAINFALL TUESDAY INTO
CHRISTMAS EVE MORNING. CHRISTMAS DAY WILL BE DRY AND MILD WITH
HIGHS RISING WELL INTO THE 60S FOR MOST. NEXT CHANCE FOR RAIN WILL
BE AHEAD OF ANOTHER COLD FRONT ON THE SECOND DAY OF CHRISTMAS.
RAINFALL AMOUNTS LOOK LIGHT BY THEN, TOO.
