000 FXUS64 KMRX 271134 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 734 AM EDT Mon Mar 27 2017 .Aviation...Main concern is developing storms late this afternoon and overnight. Another short-wave trough will move east from the southern Plains into the Tennessee/Ohio Valleys late today and tonight. Jet dynamics places the Tennessee Valley under good divergence aloft. A boundary layer jet is also induced across the region with 850mb jet of 30-35kts. The low-level jet and some mid- level dry air may produce localized damaging winds. Hail CAPES up to 300 J/kg will also support small hail, possibly isolated quarter size with the stronger storms. Besides the convection, another unseasonably mild day due to breezy southwest winds ahead of approaching upper trough. Southwest winds will gusts up to 20kts at TYS. Outside of convection, VFR conditions are expected at all TAF sites. && .PRELIMINARY POINT TEMPS/POPS...
