National Weather Service Office meteorologists issued a Special Weather Statement Tuesday noting that heavy rainfall and strong to severe thunderstorms were still possible tonight through Wednesday evening.

The storms were developing as of 4 p.m., Tuesday, west of the Mississippi River, and although some of the isolated cells may be possible across the Mid-state today and tonight west of Interstate 65, the main area of storms will approach Middle Tennessee after 7 p.m. and continue east through the overnight hours.

“Some of these storms could become severe with damaging winds and large hail possible. Although a very low threat, an isolated tornado cannot be ruled out tonight, with the best chance occurring west of I-65 further south near the Alabama border. Again, this chance appears low and will not resemble the storms that affected Oklahoma (on Monday),” meteorologists said in the statement.

At the time the statement was issued, they said it appeared that thunderstorm complexes that moved into Middle Tennessee would be weakening overnight, perhaps dissipating by Wednesday morning. Even so, “This will leave room for our region to become unstable yet again…with strong to severe storms possible Wednesday afternoon and evening. The main threats with those storms on Wednesday will be large hail and damaging winds…mainly along and east of I-65. In addition, any storms that occur throughout the next 24-36 hours will be capable of producing torrential rainfall, and if storms train over the same areas isolated flash flooding may become possible.”
