Area Forecast Discussion National Weather Service Nashville TN 1217 PM CDT SAT AUG 27 2016 .DISCUSSION... Will be updating the suite of forecast products to remove morning word references in the zone forecast product. Will also tweak hrly temp, dewpoint, and wind speed/direction grids. Remainder of forecast continues to be on track. && .DISCUSSION... Updated the suite of forecast products to illustrate the fact that moclr skies are expected thru the remainder of the morning hrs, with diurnal influences kicking in by the afternoon hrs, supporting ptcldy skies. Looks like best chance of showers/thunderstorms will also be during the afternoon hrs. Tweaked hrly temp, dewpoint, and wind speed/direction grids also. Remainder of forecast continues to be on track. && .AVIATION... 18Z TAF DISCUSSION. VFR conditions expected thru 28/18Z. Several amendments possible at terminals thru period if convection develops at terminals. With a summertime wx pattern will be in place per ridging influences sfc/aloft, enough low level moisture will be around to support development of mainly diurnal based convection. As with a summertime convective pattern also, can not guarantee convection will happen at terminals, but certainly can not rule out in vicinity thru at least 28/02Z. If convection develops at/near terminals, MVFR fog could develop CKV/BNA, with MVFR/IFR fog developing CSV 28/08Z-28/14Z. From 28/14Z-28/18Z..there could be some diurnal initialized few/sct cu/ac approaching 28/18Z...but enough uncertainty at this time/minimal impact to aviation interest, to mention at terminals at this time. Light SE to SW winds expected thru 28/18Z. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......31 AVIATION........31
