104 FXUS64 KMRX 211725 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 1225 PM EST Sun Jan 21 2018 .AVIATION... VFR ceilings across the forecast areas generally in the 5-7 kft range. Expect clouds will decrease throughout the afternoon as an upper level ridge amplifies across the region. The models differ a great deal overnight with fog formations. NAM soundings suggest LIFR visibilities with the GFS indicating VFR conditions. For now, have gone with MVFR visibilities at TYS and TRI where the low level moisture will be a bit higher. Models are consistent with MVFR ceilings moving in at CHA late in the TAF cycle ahead of the next system with southerly winds increasing during this timeframe as well. && .MRX WATCHES/WARNINGS/ADVISORIES...
