Synopsis
A large area of high pressure over the great lakes will drift
gradually to the east, reaching northern new england on Sunday.

This weather feature will bring us a several day string of dry
and cooler weather with low humidity right into early next week.

Near term until 6 am Saturday morning
The wave riding the front is finally moving far enough to the
east to take the rain away from the sern counties. Lower clouds
are diurnal in nature and should die off quickly this evening,
perhaps before sunset. The high clouds should linger thru
midnight in the se, but will be diminishing on the whole
elsewhere. Air river water temp difference to night will likely
lead to the dendritic fog in the northern valleys. Some of the
central valleys may also see fog try to form. Fog elsewhere is
unlikely due to the dry air. Ought to be refreshing air. A small
taste of autumn, ESP across the northwest half of the cwa.

Thank the canadians for this night's comfortable sleeping
weather.

Short term 6 am Saturday morning through 6 pm Saturday
Fog burns away after an hour or two, and a mostly sunny day
results. Just a few CU over the mtns. Modified cp airmass
visits for the weekend. Tough to beat guidance on maxes on days
like sat. Mixing gets up near 8h where temps are 6-9c. We should
end up in the u60s across the higher hill tops of the west and
north, and m70s in the warmer valleys of the east. These values
are generally 4-8f below normal.

Long term Saturday night through Friday
Patchy valley fog is possible once again Saturday night, as high
pressure provides mainly clear skies and light winds. Any fog
should burn off quickly Sunday morning, giving way to partly to
mostly sunny skies. Temperatures will remain slightly below
normal for late-august.

Heading into next week, the main question will be how quickly
return flow develops and brings moisture back into the area.

The GFS continues to be a bit more bullish, although it is
slowly coming more in line with the ECMWF in keeping central pa
mainly dry until Tuesday. Given the uncertainty, went with a
model blend and gradually increase pops later Monday into
Tuesday. Pops should peak on Wednesday with a frontal passage,
with a drying trend for the later part of next week.

The temperature forecast is less certain early next week, as
an increasing southeasterly low-level flow may advect some
clouds into the area and result in another relatively cool day
on Monday. Some moderation in temps is expected ahead of an
approaching cold front tues into wed. Following the midweek
frontal passage, cooler and drier weather should return late
next week.

Aviation 22z Friday through Wednesday
High pressure and associated dry air mass will build southeast
from the grt lks tonight and Saturday, providing the region with
mainlyVFR flying conditions and light north to northeast winds.

The only exception will be in the valleys of northern pa, where
late night valley fog is very likely. Kbfd is the most likely
airfield to be affected, with odds of ifr conditions close to
50 percent. Latest lamp and namnest support onset of valley fog around
midnight and dissipation by around 14z Saturday.

Outlook
Sun... Am fog possible.

Mon... Am fog possible. SE low level flow, low clouds poss.

Tue... Shra poss, mainly w.

Wed... Cfropa. Shra tsra likely.

Ctp watches warnings advisories
None.

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.
