.SYNOPSIS...
High pressure will build in from the west today cresting over
the area late in the day. High pressure will move east of the
region tonight. A weak cold front will cross the area Sunday.
High pressure will build south of toward the area Monday
through Wednesday.
&&
.NEAR TERM /THROUGH SUNDAY/...
Showers associated with the passing cold front have diminished
and only a few lingering clouds are left as it moves off the
coast. Enough of a pressure gradient remains between the
departing front and the high building in behind it that winds
are likely to stay at a light breeze through early this
morning. Thus, despite the clear skies developing over the area
currently enough mixing may occur to prevent fog from developing
as readily as it might otherwise under calmer conditions. Some
patchy fog is still possible early this morning in the most
vulnerable areas. The breeze should also prevent strong
radiational cooling and thus have only reduced valley temps in
the North Woods slightly from the NBM. Still, some patchy frost
is possible there as temps may get down to the mid 30s.
High pressure today will lead to clear skies with near to
slightly above normal temperatures. Expect highs in the 60s over
the north with areas further south approaching 70. High
pressure drifts south this evening over the Gulf of Maine while
a cold front approaches from the west. Clouds should begin to
build into the area with mostly cloudy skies overnight. This
should prevent strong radiational cooling so thus have not
deviated from the NBM aside from in the far northwest where
skies are expected to remain the clearest. Some patchy fog also
possible, especially in those areas that see the clearest skies.
The cold front crosses the region on Sunday bringing some
showers to northern Maine early before tracking south. The
greatest chance for precipitation is in northern and eastern
Maine while some uncertainty still exists as to if showers will
be able to develop farther south and west along the cold front.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
West to Northwest flow both at the surface and aloft can be expected
Sunday night through Monday night. Expect mainly clear skies
both Sunday night and Monday night, with a mainly sunny day
expected on Monday. Afternoon highs on Monday will be around 70
degrees across the north and mid to upper 70s for central and
downeast areas.
&&
.LONG TERM /TUESDAY THROUGH FRIDAY/...
High pressure will be centered near James Bay Tuesday and then
slowly build toward the area through Thursday. An upper level
trough will cross the region on Wednesday. The main impact with
this feature will be to send a reinforcing shot of cold air
advection across the area Tuesday night and Wednesday. Afternoon
highs on Wednesday will be several degrees below normal. A
gusty north to northwest wind can also be expected. Some
moderation is expected by Thursday, but afternoon highs will
still be a few degrees below normal for this time of year. High
pressure will sink to our southwest Thursday night and Friday.
This will bring milder air into the region by Friday afternoon
ahead of another cold front approaching from the northwest.
&&
.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...

VFR Saturday aside from a chance for patchy fog
early this morning and tonight. The greatest chance for fog is
