Area Forecast Discussion National Weather Service Nashville TN 448 PM CDT Sat Aug 29 2020 .UPDATE... FOR EVENING DISCUSSION. && .DISCUSSION... Updated late afternoon zone grouping for better depiction of showers and thunderstorms moving into northern parts of mid state region. Initialization with best chances expected across Upper Cumberland Region approaching evening hours best depicted by CAMs HRRR/CONSShort Blend. Tweaked hourly temperature, dewpoint, and wind speed/direction grids. Remainder of forecast continues to be on track. && .AVIATION... 18Z TAF DISCUSSION. The few remaining MVFR clouds should continue to scatter out. Weak boundary across the plateau may be a focusing mechanism for a few storms this afternoon and evening...coupled with a weak cold front that moves into the state. This means there could be VCTS for all TAF sites 22-02Z. Since CSV has a better chance will include a TEMPO from 20-24Z for peak time. Overnight winds drop off and have light BR for CKV and CSV. Westerly winds today will drop off overnight and become more easterly tomorrow. VCTS expected again tomorrow after 14-16Z. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......JB Wright AVIATION........12
