Widespread showers across the forecast area this morning as a shortwave tough progresses across the Southern Appalachians. So far, have not seen any lightning with the activity with the closes lightning currently along the Gulf Coast. At the surface, the cold front is still back to the west of Nashville and could still see some storms fire along this boundary later this afternoon. For the update, increased PoPs across NE TN and SW VA where it looks to rain throughout the remainder of the day. Due to this, also reduced the high temperatures in these locations where rein is expected to persist. Rainfall rates have not been overly impressive and 3 hr FFG values remain in excess of 2 inches across most of the area, therefore, do not anticipate issuing a flash flood watch at this time. There will be some ponding of water in areas of poor drainage but no widespread flooding issues are anticipated.
