.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
Late afternoon update.

Adjusted TAS for current showers and storms and trends with
winds.

Held onto TEMPO group at LNS, nothing much down that way,
but still some chc of a storm working southward into that
area next few hours.

Earlier discussion below.

The main focus through the 12Z Friday will be a shortwave that 
will traverse the region and bring mainly isolated showers and 
thunderstorms to portions of the area into early this evening
(across mainly the eastern half of the CWA) as a surface cold 
front (associated with this upper level shortwave) pushes SE 
across the SE half of the state. 

This cold front will be largely moisture starved, However, 
given the instability in the eastern portion of PA it is 
possible isolated to scattered storms may cause some flight 
impacts.

These thunderstorms will have the best chance of impacting IPT,
MDT, and LNS, while areas farther to the west likely remain 
dry. 

Generally VFR tonight and for the entire long holiday weekend,
but a brief few hour period of fog is possible at KBFD and at
other airfields in the valleys of central and eastern PA.

Outlook...

Sat-Sun...AM fog possible; otherwise VFR.

Mon-Tue...Thunderstorms developing in the afternoon.
