.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.
