000 FXUS64 KMRX 211518 AAB AFDMRX Area Forecast Discussion...UPDATED National Weather Service Morristown TN 1118 AM EDT Fri Apr 21 2017 .DISCUSSION...
-- Changed Discussion --
Area of light to moderate showers still moving across upper east Tennessee into southwest Virginia. This activity should move out over the next couple of hours -- though the potential for additional showers and isolated storms will exist throughout the remainder of the day. Elsewhere across the region, a mostly clear sky is prevailing over the central and southern valley, helping to destabilize the environment somewhat for the afternoon. MLCAPE values may reach the 500-1000 j/kg range by the afternoon in these spots, with a weak front helping to focus this activity. Therefore, there will be an opportunity for scattered storms -- some strong to marginally severe to develop in the 18-00z window later today. The main threats will be locally heavy rainfall and damaging gusty winds.
