Area Forecast Discussion National Weather Service Nashville TN 220 PM CDT Tue Jun 26 2018 .UPDATE... FOR AFTERNOON DISCUSSION. && .DISCUSSION... Updated suite of forecast products to reflect current radar regional mosaic trends thru remainder of afternoon hrs. && .AVIATION... 18Z TAF DISCUSSION. CKV/BNA/MQY/CSV....A lot of uncertainties when it comes to aviation forecast thru 27/18Z per how unstable atm environment is versus will there be any significant forcing lifting mechanics in place to support convective development at/near terminals. Will on the whole lean toward VFR ceilings/vsbys now, but potential actual impacts of shwrs/tstms developing at or moving across terminals could certainly alter that. On the whole, believe VCTS appropriate for all terminals thru 27/02Z-27/04Z. Should generally be VCSH 27/04Z-27/09Z. As base of an upper level trough begins to move across the mid state region 27/09Z-27/18Z, a more pronounced chance of shwrs/tstms anticipated with all terminals potentially experiencing MVFR vsbys. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......31 AVIATION........31
