000 FXUS64 KMRX 182358 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 658 PM EST Sat Feb 18 2017 .AVIATION...Deep moisture resides across the Great Valley this evening in the circulation around a Lower Ohio Valley upper level low. A weak disturbance within this circulation will move across the Southern Appalachian region overnight generating a couple sprinkles. However, the main impact on flight operations will be mvfr and even some ifr ceilings hanging around through the overnight hours. Additionally, there should be some fog development. Would expect visibility to stay in an mvfr category due to the protective blanket of low ceilings. Slow improvement will occur in the lower category flight weather on Sunday with a gradual return to vfr conditions as some drier air filters in behind the departing upper low. && .MRX WATCHES/WARNINGS/ADVISORIES...
