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.


Stratocumulus is collapsing early this evening with loss of
daytime heating and stable stratification from strong high
pressure extending from eastern Ontario to central Quebec.
Another cool dry night brings 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


Sunday will be a virtual carbon copy of today, but with a bit
less stratocu over the west. Patchy fog early will burn off
quickly leading to another bright but cool day. Highs will be a
tad warmer as the airmass modifies. This will be followed by
another quiet night, but not quite as chilly over the northern


High pressure will dominate the near long term; however, a
southeast flow developing as high pressure slides east of New
England will bring low level moisture to the southeast areas
Monday night.

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.


High pressure and associated dry air mass will build southeast
from the Great Lakes, ensuring VFR conditions and light winds
through Sunday over most of central Pa. The only exception will
be in some of the river/stream valleys of central Pa, where late
night fog will form. NAMNest and LAMP guidance indicate fog will
develop around 07Z and dissipate by 13Z-14Z Sunday. KBFD, KIPT,
KAOO and KUNV are the only airfields that stand a slight chance
of vis reductions early Sunday morning.


Mon...AM low cigs/fog possible.

Tue...AM low cigs possible Allegheny Plateau.

Wed...Showers and AM cig reductions possible.

Thu...No sig wx expected.




LONG TERM...La Corte/Tyburski
