Area forecast discussion 
National Weather Service Gray ME 
832 PM EST Tuesday Dec 2 2008 


Synopsis... 
a ridge of high pressure will move across the northeast tonight 
then slide off the coast Wednesday and Wednesday night. A cold 
front will move southeast across the region and off the coast late 
Thursday. High pressure will build in from the west Friday then 
move offshore Saturday. Low pressure will move northeast well off 
the coast while a trough of low pressure crosses New England 
Sunday and Sunday night. The trough will intensify into a low 
pressure system off the coast on Monday then track to the east 
Monday night as high pressure builds in from the west. Low 
pressure will move in from the west on Tuesday bringing a chance 
of precipitation. 


&& 


Near term /until 8 am Wednesday morning/... 
weak surface trough will quickly push east of the forecast area 
early this evening followed by a ridge of high pressure. Clouds 
associated with this feature will clear this evening downwind of 
the mountains. In the north clouds will linger along with just a 
slight chance of a snow shower this evening with clearing towards 
morning. 


830 PM update...mostly clear skies over southern/coastal sections 
with clouds still evident over northern/mountain sections. 
Winds have gone slack since sunset. Will update zones to adjust 
some cloud conditions with no other changes anticipated at this time. 


&& 


Short term /8 am Wednesday morning through 6 PM Wednesday/... 
Wednesday looking quite nice as high pressure pushes offshore and 
return flow brings warmer air back into the region under mostly 
sunny skies. Have gone a few degrees above mav numbers which look 
a little low considering 850 temperatures at 18z. Expect just a few high 
clouds to spill into the region in the afternoon. 


&& 


Long term /Wednesday night through Tuesday/... 
a ridge of high pressure will move off the coast Wednesday night 
as warm air continues to surge into the NE on a SW flow. A cold 
fnt will move southeast across the region and off the coast late 
Thursday. This will bring some -shra to the region during the day 
Thursday. Much colder air will move in on gusty northwest winds behind 
the fnt with upslope -shsn over the Montana zones. 


High pressure will build in from the west Friday then move offshore 
Saturday providing fair weather. Low pressure will move NE well off 
the coast while a trough of low pressure crosses New England Sunday 
and Sunday night. The offshore low is too far out to sea to impact 
the forecast area but the trough could kick off some -sn or -shsn. The 
trough will intensify into a low pressure system off the coast on 
Monday then track to the east Monday night. Low pressure will move east toward 
the region on Tuesday bringing a chance of prcp to the region Tuesday 
into Wednesday.

Aviation /02z Wednesday through Sunday/... 
short term /through Wednesday/... 


Short term...VFR tonight through Wednesday. 


Long term /Wednesday night through Sunday/...MVFR conditions possible 
with any -shra on Thursday across the taf sites. MVFR and possibly 
IFR conditions may occur on Sunday with any -shsn. 


&& 


Marine... 
short term /through Wednesday/... 


Short term...continuing Small Craft Advisory for winds and seas through 700 am Wednesday 
but expect both to drop off after midnight. 




Long term /Wednesday night through Sunday/...SW winds and seas 
will increase to Small Craft Advisory strength with gale force gusts possible as the 
cold front approaches from the west late Wednesday night and Thursday. Small Craft Advisory 
winds should continue Thursday night and Friday in the cold air advection 
pattern behind the departing fnt. High pressure building in from the west 
will slowly cause winds and seas to drop off through Saturday. At 
this time the ocean low is forecast to track far enough out to sea on 
Sunday so that it won't impact the coastal waters.
