.AVIATION /18Z WEDNESDAY THROUGH MONDAY/... 

As of 18Z, widespread rain is overspreading the region, leading
to IFR conditions taking shape in the afternoon and into the 
evening. Cloud ceilings will take some more time to lower in 
MDT & LNS; they will likely remain MVFR for longer before a 
transition to IFR. 

The combination of precipitation lowering visibilities and 
cloud ceilings during the evening and overnight leads to 
confidence in LIFR development during this TAF period in BFD, 
JST, AOO, and UNV. Ceilings and visibilities look to improve 
throughout the morning as drier conditions set in. 

A low pressure system and cold front will travel west to east
through the forecast period, leading a wind shift sweeping
across PA. The southerly flow regime will be replace by one out
of the northwest. BFD will see the wind shift first in the 
evening and it crosses MDT & LNS in the late night/early
morning. Winds are expected to be light region wide with some
gustiness possible late in the TAF period for MDT & LNS.

Outlook...

Thu... Drier conditions set in, mainly MVFR & VFR with BFD
possibly having some IFR linger into the afternoon. VFR will be
favored in the afternoon with many areas seeing decreasing cloud
cover. 

Fri-Sat...Mainly VFR with brief restrictions possible in 
showers.

Sun...Restrictions possible northwest in -RA and possibly some
-SN.

Mon... Models hinting at another low pressure wave to our west,
precip may lead to restrictions, particularly in the west.
