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
Relatively tranquil conditions were noted across all of central
pa early this morning with varying amounts and thickness of mid
and high clouds streaming ene over the state. The origin of
this extensive, anti-cyclonic plume of moisture was from the
tropical pacific to the west of southern mexico.
As the high to our NW approaches the lower great lakes and
ridges into the region, some slight veering to the mid and upper
flow and dry advection aloft will occur and allow for the mid
and high cloud deck to shift slightly south to mainly the
southern third to half of pa this afternoon and tonight.
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
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
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
Pws will stay between 0.25 and 0.35 of an inch today and
Short term Saturday and Saturday night
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 Sunday 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.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
