.NEAR TERM /THROUGH TODAY/...
-- Changed Discussion --
Update...
A cold front will cross the region overnight with partly cloudy
skies along with isolated to scattered showers across northern
areas, with partly cloudy/mostly clear skies across the
remainder of the region. Low temperatures will range from around
40 to the mid 40s north, to the upper 40s to around 50 Downeast.
Have updated the forecast to adjust for current conditions along
with overnight temperatures, cloud cover and shower chances.

Previous discussion...
Friday will be a nice day although it will be a little cooler
as a drier airmass on NW winds moves into the region. It will
be mostly sunny with breezy NW winds and temperatures trending
about 10 to 15 degrees cooler.

.SHORT TERM /TONIGHT THROUGH SUNDAY/...
Our dry and mild weather will continue through the weekend as a
strong ridge high pressure builds in from the west. Friday night
will be mainly clear with lows from the low 30s north to the upper
30s Downeast. High pressure both surface and aloft building onto the
east coast will then bring plenty of sunshine Saturday as highs
reach the 50s north and low 60s Downeast. Sunday will be even warmer
as the upper level ridge builds over with highs in the 60s
throughout the area. However, some moisture topping the ridge
combined with a bit of warm advection sliding north behind the
surface high pressure may produce some mid and high cloudiness,
especially across the north, on Sunday.
&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
A southerly flow will increase Sunday night into Monday as high
pressure moves to our east into the open Atlantic. Dry weather will
persist into early Monday. A band of moisture may then approach late
Monday along a boundary between departing high pressure and a large
trough approaching from the upper Midwest. Some showers will become
possible late Monday into Monday night along this boundary. The
midwestern trough will intensify and deepen on Tuesday as the high
to our east anchors in place. This will result in a
strengthening gradient between the high to our east and the
trough pushing in from the west, and as a result, an increasing
south wind Tuesday into Tuesday night. Some showers, possibly
heavy, may occur along the front as it pushes in from the west
Tuesday night, and south winds may become very strong by Tuesday
night. The front is expected to push to our east later
Wednesday into Wednesday night. There continues to be a
possibility that a secondary low will form along the front off
the southeast coast and race north, possibly bringing rain, late
in the week.
