000 FXUS64 KMRX 191440 AAA AFDMRX Area Forecast Discussion...UPDATED National Weather Service Morristown TN 1040 AM EDT Wed Jul 19 2017 .DISCUSSION...
-- Changed Discussion --
Surveying the regional 12Z raobs and GOES-16 derived stability indices, areas to our south will have the greatest moisture and instability this afternoon, with drier and more stable conditions to our north. The latest runs of the HRRR and RAP develop some convection in the southern Valley and Plateau this afternoon. The NAM has precip in SW VA today, but this doesn`t jive with what the observations suggest. The forecast update will add a slight chance PoP to southern sections and the Smokies, and remove the low PoP in northern sections this afternoon. Temperatures appear on track.
