For today, late afternoon into the night (not a solid shield but rotating over many) and scattered rain into the afternoon tomorrow. 3K is similar though a bit less later tomorrow. This eventual solution really caught many off guard. AFD from NWS just 48-60 hours ago was mostly dry.
As for the daily sensible weather, slim shower chances persist
across portions of the lower Susquehanna Valley Monday/Tuesday
nearer the upper forcing and greater moisture source. Wednesday
and early Thursday look dry and fairly mild, as a warm
advective southwesterly flow develops ahead of an approaching
surface cold front. The just mentioned cold front is progged to
cross the Commonwealth by early Friday, accompanied by at least
scattered showers. The end of the week through at least next
weekend looks to turn noticeably cooler at this time, as a very
chilly air mass drops down from south-central Canada. The
combination of this chilled air moving over the warmer Great
Lakes waters, plus short-wave energy aloft should lead to at
least scattered showers over northwestern PA and the
Alleghenies. Farther east towards the Susquehanna Valley,
downsloping should produce mainly dry weather.
