The Storm Prediction Center (The severe weather forecasting arm of the National Weather Service) has placed a large part of middle and west Tennessee in a "Moderate Risk" area for strong to severe storms today. (Roughly a 4 out of 5 chance for severe storms at a given point). The remainder of middle TN is in an "Enhanced" area or roughly 3 out of 5 chances.
All modes of severe weather are possible...but the greatest threat will come from large hail and damaging winds.
Bottom line today...EVERYONE should be weather aware today - into tonight. (This may wind up being more of a night time event...models are not in good agreement.)
