Extended Forecast

Wednesday – Thursday: Chance showers and storms. Some storms could be severe.

Friday: Partly cloudy.

Saturday: A chance for showers and storms.

Sunday: Scattered showers and thunderstorms.

Monday: Partly cloudy.

Radar Simulation

This radar simulation begins at 1:00 p.m. today and ends at 10:00 p.m. tonight. Notice the big complex of storms moving across Kentucky during the day. If any storm fires off to the south of that complex and moves into TN, that storm would likely be severe. This particular model brings a better chance of storms to the area around 10:00 p.m. but that is uncertain. Notice this model keeps us dry through the afternoon and early evening, but that is definitely not certain and any storm that does form will have to be taken seriously.

MM’s Severe Wx Concerns 

Severe Weather Safety 

On This Day

1995- A large outbreak of supercell thunderstorms strikes Middle Tennessee. There are 16 confirmed tornadoes across the mid state, including an F-4 which tears a 29 mile path across Lawrence and Giles Counties, killing three, and injuring 32. Another massive F-3 tornado carves a 1/2 mile wide swath across Cumberland County, ending on the south side of Crossville. A swath of hail damage extends from near Linden to Shelbyville, causing extensive damage to homes and vehicles. Hail as large as 3″ is reported. Another hailstorm in De Kalb County produces an estimated $1.5 million in damage. This is the 5th largest tornado outbreak in mid state history. (This is the subject of my MM weekly newsletter at

The latest newsletter was released Friday, as it is each and every Friday! This newsletter focuses on the violent tornado that struck the Tansi community in May of 1995. That was a phenomenal storm that, after many quiet years, reminded us of our vulnerability to severe weather. Find out about this and more at! Proceeds from subscriptions go toward supporting the MM kids classes taught monthly at both TCAT Crossville and Roane State Clarkrange.
