.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
Main changes to the 06Z TAF package was to add some fog to MDT
and LNS, as these areas are already cold. Further west the 
temperatures are warmer. Some clouds at BFD as well. These 
factors may limit fog formation to the west overnight.

Other change was to extend fcst out to 06Z Monday. Still expect
some snow and rain to linger overnight Sunday night.

Earlier discussion below.

VFR conditions will continue throughout the night for most sites
as high clouds begin to build in over the region ahead of the
upper level trough and surface low expected to arrive Sunday
afternoon. The only airfield expected to see flight restrictions
will be BFD overnight tonight. Little to no winds and increased
surface moisture could result in early morning fog or very low
stratus by daybreak. Everywhere else should see VFR through
Sunday morning with ~90% confidence. 

Precipitation arrives late Sunday afternoon beginning in the
Laurel Highlands as a very cold rain. Expect visibility
reductions throughout the afternoon as this stratiform shield 
of precip spreads from west to east. Most everywhere will see
MVFR conditions or worse by 00Z Monday due to low clouds and
precip. Mixing of rain and snow could occur where cooling is
most efficient, the greatest possibility to see rain mixed with
snow will be at LNS and MDT.

Outlook...

Mon...Low clouds linger much of the day. IFR expected NW. 

Tue...Mainly VFR.

Wed-Thu...IFR -RA/cigs N, MVFR -RA/cigs elsewhere.
