206 FXUS64 KMRX 271444 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 1044 AM EDT WED JUL 27 2016 .DISCUSSION...Forecast on track for the most part. Still expecting isolated to scattered afternoon convection as we remain in a moist environment and as temperatures heat up through the afternoon. There could be a few strong storms this afternoon as soundings show 2000 J/KG MLCAPES by around 18z. The biggest threat for today will be locally heavy rainfall as PWS are very high for this time of year. Shear is again on the weak side today which should help to dampen any severe threat. The biggest change to the forecast was to lower temps across the southern valley by several degrees as some thicker cloud cover looks to move in from the southwest out of northern Alabama. These thicker than anticipated clouds will keep Chattanooga and the extreme Southern Valley a few degrees cooler than previously forecast. New zones out soon to account for temp adjustment. && .PRELIMINARY POINT TEMPS/POPS...
