.NEAR TERM /UNTIL 7 AM SUNDAY MORNING/...
A few stay isolated showers and storms remain in the CWA,
however the threat for severe weather and flooding has mostly
ended for the evening. Low status and billow clouds over the
eastern half of the CWA kept the airmass mostly stable through
the early afternoon hours preventing the line of storms that
came through from being too unruly. The aforementioned clouds
eventually broke up, allowing for some airmass modification and
a few storms to kick up in the Lower Susquehanna Valley, but
instability was limited due to the short amount of time that
area saw direct sunlight.

The remaining convection over CPA will dissipate over the next
couple hours, and rain chances drop to near zero just after
midnight tonight. Given the ample moisture across the ground and
diminishing winds overnight, widespread patchy fog is expected
to develop across most of the area. Anticipate some visibility
reductions, especially during the pre dawn hours of the morning.
Lows tonight will reach near 70 across the southeast to the
upper 50s in the northwest mountains.

&&

.SHORT TERM /7 AM SUNDAY MORNING THROUGH MONDAY NIGHT/...
Sfc high pressure building into CPA behind the front provides a
dry period tonight through Sunday.  Sunday will see a return of
sunshine, drying conditions, and warmer temperatures once high
pressure is in control. High temps on Sunday will reach the low
80s across the northern tier of the commonwealth to the low 90s
near south central PA along the Mason Dixon line.

The stormy and unsettled pattern resumes early next week with a
shortwave trough progressing through the Great Lakes sending a
quasi stationary/warm and cold front through the region Monday
and Tuesday. Partly cloudy skies to begin the day on Monday will
allow for plenty of destabilization of the atmosphere. That
combined with ample moisture returns from the south will provide
the ingredients for another round of strong storms Monday
afternoon ahead of and along the front. Isolated strong to
severe thunderstorms with gusty winds and heavy rainfall are
possible.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
For now, the signal is relatively weak for rainfall leading up
to the 4th of July. However, another northern stream front will
keep low POPs in the forecast for Independence Day. Whether or
not we see precipitation for the 4th will be dependent on how
quickly the upper level low lifts out of New England and gets
replaced by building region over the central US. Temperatures by
the middle of next week are progged to be just above to near
climo.

&&

.AVIATION /23Z SATURDAY THROUGH THURSDAY/...
Scattered showers and a few thunderstorms will continue to
drift eastward across the area, mainly south of I-80, this
evening. A localized downpour is possible.

As skies clear overnight, there is the potential for fog
development. Have hinted at this possibility in each of the
TAFs, and hit BFD the hardest where the confidence is the
highest in reduced vsbys.

After any fog mixes out, expect dry weather and widespread VFR
conds for Sunday.

The next cold front will arrive early next week. Some of the
accompanying storms could be on the strong side once again.

Outlook...

Sun...AM fog, then VFR.

Mon-Tue...SHRA/TSRA expected, with periods of fog and low
clouds overnight.

Wed...AM fog, then VFR.

Thu...Primarily VFR, although a few aftn SHRA/TSRA are
possible.
