Synopsis
High pressure centered over the upper great lakes early today
will build east and become located over upstate new york
tonight. This weather feature will bring fair and milder weather
to pennsylvania to close out the week.

The high pressure area will drift off the southern new england
coast on Saturday, and a gusty southeast to south wind will
develop with clouds thickening up during the day followed by
a soaking rain late Saturday into early Sunday. The air could
be cold enough late Saturday afternoon and evening throughout
the valleys of central pennsylvania for the rain to begin as
a brief period of freezing rain.

Gusty and potentially damaging westerly wind gusts will develop
in the wake of cold front late Sunday morning and will continue
through midday Monday.

Near term through tonight
Varying amounts of high clouds streaming overhead across central
pa, while thicker mid cloud covers the south, and mostly sunny
conditions are over the north. This should continue to be the
case this afternoon as the high provides a drier flow to areas
north of i80 through late afternoon.

Winds will be light today with MAX temps near, to perhaps a few
deg f above normal in the east (or lower 40s) and 4-7 deg f
above normal over the western mtns (in the upper 30s to low
40s).

Skies will be clear to partly cloudy across central and
northern pa tonight, while varying amounts of mid and high
clouds will persist across the southern few layers of pa
counties.

Lows tonight will be cool (in the upper teens throughout the
perennial cold spots up north, to around 30f in the south thanks
to the cloud cover), but still a few deg f above normal in many
locations.

Pws will stay between 0.25 and 0.35 of an inch today and
tonight.

Short term Saturday
Pws will jump upward to moderately high levels (0.75 to one
inch) during the mid to late morning hours Sat across the sw
third of pa, and during the afternoon hours central and nepa.

Clouds will thicken-up during the day with rain spreading in
from the south southwest early Sat afternoon acrs the laurel
highlands, and during the mid to late afternoon hours elsewhere
as a neg tilt 850-700 mb trough moves northeast.

Higher pwat air (between 1-1.25 inches) will spread in from the
ohio river valley Saturday night and a soaking rainfall for 7 to
9 hours will ensue as uvvel increases at the nose of a 55 to 65
kt swrly llj. Consensus rainfall amounts are between 0.6 and 1.0
inch by around sunrise Sunday, which should be very manageable
regarding stream levels since a significant percentage of the
snow from the midweek storm melted on Thursday, and most will be
gone and flowing into the larger tribs and rivers before the
bulk of the rain arrives late Saturday into early Sunday.

Long term Saturday night through Thursday
Focus shifts toward the potential of strong winds Sunday pm, as
trailing cold front sweeps through the area, allowing strong
winds associated with grt lks storm to mix to ground level. This
scenario of a powerful low passing north of pa fits the pattern
we see with our strongest winds across central pa and a quick
look at model 850mb winds suggest >50kt gusts are possible.

Issued a high wind watch for our entire area from late morning
Sunday into Monday afternoon, and maintained basically the same
wording for strong winds in the hwo.

As the temperatures continue to warm aloft, expect a likely
surge to springlike readings Sunday. The shallow cool air should
mix out then there should be a return to seasonal readings for
next week. Med range guidance points toward dry weather early
next week, as high pressure builds across the region. However,
model spread and forecast uncertainty ramps up by the middle of
next week concerning the track, timing and strength of a fast
moving shortwave approaching from the midwest. Given when the
instability is for the storm next midweek, have changed precip
type to mostly snow.

Aviation 18z Friday through Wednesday
Vfr flying will continue over the next 24 hours with sct-bkn
high clouds and light variable winds.

Outlook...
