Visibility has improved across portions of northeast TN and southwest VA where early morning fog was prevalent. Thus, mostly sunny skies prevail across the vast majority of the fcst area this morning amidst modest warming and light surface flow. As for the fcst, tweaked pops a bit to align with recent CAM solutions/timing which favor convective initiation across the southern Apps as well as the lower regions of the Plateau early this afternoon. From there am expecting some expansion along the US64 corridor, northward toward I40. However, think capping will hold for the most part north of I40. Also adjusted max temps down around a degree across the aforementioned AM foggy areas given trends are a good bit behind previous fcst. No other changes needed/made with this update.
