Area Forecast Discussion National Weather Service Nashville TN 1009 AM CDT Fri Jul 14 2017 .UPDATE... FOR MORNING DISCUSSION. && .DISCUSSION... Latest surface observations and radar imagery show an outflow boundary from overnight convection in the Ohio Valley has sagged south to a line from roughly Erin to Jamestown. This boundary will be a focus for convection today, and indeed latest radar scans show showers and storms rapidly developing along the boundary this morning as convective temperatures are reached. 12Z OHX sounding shows steeper lapse rates aloft and a bit more MLCAPE versus yesterday, so anticipate a better chance for a few strong storms with wet microbursts from late this morning into the afternoon, along with potential for localized flooding. Only update to forecast was to nudge pops up for today in northern zones. && .AVIATION... 12Z TAF DISCUSSION. Cold front located just north of the Ohio river this morning. As this feature works our way, showers and thunderstorms will develop, primarily this afternoon and evening. Will include prob 30's for convection for roughly the 18z through 00z period. Otw, following the scattered showers and tstms, light fog will occur aft 06z. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......Shamburger AVIATION........08
