Synopsis
A large area of high pressure over the great lakes will drift
to the east reaching northern new england on Sunday, providing
several days of cool-dry weather on its journey.

Near term through tonight
Night time blended imagery shows fog starting to fill the
valleys of the north, as well as some low clouds over the higher
elevations of the laurel highlands southward.

The fog and low clouds will burn off quickly after sunrise
leading to a bright but cool day over the forecast area. Highs
in the 70s will average well below normal for late august.

More of the same is in store tonight with comfortable sleeping
weather and little more than patchy valley fog for sensible
weather. Lows look to average about 3-6 deg below what they
should normally be.

Short term Sunday
Sunday will be a virtual carbon copy of today. Early fog will
burn off quickly leading to anther bright but cool day. Highs
will likely be a tad warmer as the airmass modifies.

Long term Sunday night through Friday
High pressure will move off to our NE by early next week. This
will set up a easterly flow into the mid atlantic that could
bring in some marine air low clouds later Monday into Tuesday. I
introduced the potential for some light rain in this
increasingly moist flow, but with little in the way of qpf.

Models are in decent accord in bringing a dying cold front
through the CWA for mid week, followed by mild and mainly dry
conditions late in the week and into next weekend. Other than
showers associated with the mid week frontal passage, we really
don't see any big rain opportunities for the next week.

Aviation 09z Saturday through Wednesday
For the 5 am TAF update, more in the way of mid lvl clds than i
had earlier.

Minor adjustments made to the TAF package as of 5 am.

06z tafs sent.

Took fog out of the bfd fcst. Still some wind outside. Also high
pressure building into the area today, with drier air. The main
factor is sct to bkn mid level clds outside.

Overall the weekend will feature mainlyVFR conditions, given
the high pressure system building into the area.

Good conditions may hold into Monday.

Outlook
Sun... Am valley fog likely northern pa.

Mon... Am valley fog possible.

Tue... Am low CIGS possible.

Wed... Showers and am cig reductions possible.

Ctp watches warnings advisories
None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
