.NEAR TERM /THROUGH TONIGHT/...
Update...
Have updated to adjust for current conditions.

Previous Discussion...
Low pressure lifts from the Mid-Atlantic coast to southern New
England today. The supporting upper low across the Mid-Atlantic
region then captures the surface low tonight. The surface low
wraps westward across southern New England tonight, eventually
stacking beneath the upper low. With increasing moisture,
isolated rain showers will begin to develop this morning with
scattered showers this afternoon. Otherwise, skies will remain
cloudy/mostly cloudy today. Expect increasing Atlantic moisture
tonight. Areas of rain will develop across the forecast area
tonight. The pressure gradient between the low and high pressure
near Labrador will support gusty northeast/east winds later
today through tonight with gusts of 25 to 30 mph expected. High
temperatures today will range from the lower to mid 40s north,
to the mid to upper 40s Downeast. Low temperatures tonight will
range from the upper 30s to around 40 north, to the lower 40s
Downeast.
&&

.SHORT TERM /FRIDAY THROUGH SATURDAY/...
Vertically stacked low pressure will pinwheel across eastern
Pennsylvania during Friday. Spokes of moisture will be lifting
northward across northern New England through Friday afternoon. Will
have likley to categorical pops across the entire forecast area
during Friday. That being said, high pressure will remain
across Labrador with northeast flow. That may result in
precipitation being slower to move into northeast portions of
the forecast area. Highs Friday afternoon will be in the low 40s
across the north and mid 40s for the Bangor region and
Downeast. Friday night and Saturday, the low will gradually move
east and off the coast of NJ, and then toward the Canadian
Maritime provinces by later Saturday afternoon. As the low lifts
northeast expect precipitation to continue during Saturday,
although there still is uncertainty with regard to the extent of
the heavier precipitation. Precipitation will be mainly in the
form of rain, then possibly begin to transition to, or mix with
snow across the North Maine Woods and higher terrain later
Saturday afternoon. Trimmed a few degrees off the NBM numbers
for Saturday`s highs. Generally expect upper 30s to around 40
north and low to mid 40s across the remainder of the region.
&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Surface/upper level low pressure continues to slowly exit east
through the Canadian Maritimes Saturday night through Sunday.
As colder air wraps into the region, expect rain to change to
snow across the North Maine Woods and higher terrain Saturday
night. Some snow accumulation is possible there during Saturday
night. Expect mainly cloudy skies with lingering snow or rain
across the north tapering to scattered showers later Sunday
morning and afternoon. Weak ridging builds in for Sunday night
and Monday with drier conditions. Another low pressure system
from the Great Lakes region approaches Monday night through
Tuesday, bringing the next chance for precipitation to the
region. Precipitation could linger into Wednesday but there is
a large degree of uncertainty this far out. Afternoon highs
through the period will be near or slightly above normal levels
for this time of year.
