-- Changed Discussion --
VFR conditions will remain through the early night at all three TAF sites. Low level moisture will increase ahead of a widespread area of showers and thunderstorms approaching east TN between 07Z and 09Z. Enough instability is present in areas around KCHA and KTYS for -TSRA in TAF. Left mention of thunder out of KTRI due to weaker environment expected. The low level moisture overnight will cause at least MVFR visibilities ahead of the convection...with little to no improvement expected until around or after sunrise. Widespread showers are expected through the day Sunday...with prevailing VFR visibilities and ceilings. Though ample moisture could cause MVFR or even IFR conditions with each shower and thunderstorm that moves through a TAF site.
