Main concern is convection, including thunderstorms, overnight. Convection will reduce visibility to IFR conditions at times. Greatest at TRI between now and 06Z, TYS between 03-08Z, and CHA between 05-10Z. For TYS and CHA, storms may produce gusty winds since the low-level jet is strong (850mb winds of 35-40kts). Ceiling will drop to IFR conditions as well at all TAF sites between 08-13Z. Upper jet producing the forcing will move east of the area early Saturday morning with drier air moving back into the region. Flight conditions will quickly become VFR by mid-morning Saturday. Main concern Saturday will be increasing westerly winds between 14- 20kts sustained with gusts up to 30kts.
