Synopsis
A cold front drops south through the region and pushes offshore
tonight as high pressure builds in from the northwest. A warm
front lifts into the region Sunday night triggering scattered
showers. Low pressure slowly moving northeast out of the great
lakes will drive an occluded cold front through the region
by early Tuesday with heavier showers and thunderstorms
possible. Low pressure aloft will remain in control through the
remainder of the week bringing periods of rain.

Near term /until 6 am Sunday morning/
Update...

gusty winds continue across the forecast area with
northwesterlies running between 10 and 20 kts in most areas. A
few higher gusts will continue as well over the next few hours.

Minor adjustments made to current temperatures and dew points.

Have included a stripe of persistent clouds over southern
interior areas per latest satellite images as well. Otherwise,
little in the way of changes to previous package with the
exception of new marine headlines (see marine section below).

Prev disc...

temperatures have climbed to near record values across the
region this afternoon with highs reaching into the low 80s in
some locations. Those temperatures have already begun to drop as
a cold front pushes through the region. West to northwesterly
winds will continue to gust to 20 to 25mph this afternoon.

Scattered clouds will dissipate as the front pushes into the
region overnight.

High pressure will briefly move into the region overnight into
Sunday morning. Expect temperatures to drop to near or just
below freezing in the northern mountains under clear skies as
the valleys decouple. Have gone a touch lower in the north to
account for this.

Short term /6 am Sunday morning through Sunday night/
Sunday a warm front will lift northwards through the region
touching off showers in the south around midday with expanding
precipitation across the northern mountains into the overnight.

This warm front is part of a much larger system currently
centered over the central plains which will strengthen and move
eastwards Sunday night into Monday. Most of this system will
stay to our west so have kept pop relatively low through the day
on Sunday with higher values overnight as the system is able to
progress eastward. Sundays high temperatures will be quite a bit
cooler than today reflecting more of this afternoons cold
frontal passage than tomorrow returning warmth and remaining in
the upper 50s to low 60s.

Long term /Monday through Saturday/
A pool of cold air stationed over north central canada will dip
south towards northern new england this week, facilitating periods
of precipitation and cooler weather. On Monday ridging aloft
will shift east as the cutoff low over the southern plains
ejects northeast. This low will phase with northern stream
energy and swing through the region by Wednesday morning.

Another upper low will arrive for the weekend and linger for at
least a couple days.

At the surface, a warm front will be lifting into the area very
early Monday. Showers will be concentrated along the higher
terrain and along the boundary which will be stretched across
northern nh and western maine. Depending on how much of the
region stays in the warm sector and how far east and north the
warm front gets during the day, we could see 60s over much of
nh, with 50s and upper 40s more likely as one moves east.

An occluded front moves through late Monday bringing a line of
showers and embedded thunderstorms through during the overnight
period and into the early morning hours. Not expecting anything
more than some rumbles of thunder at this point. Pw values do
jump up quickly along the front so there will be some heavier
downpours. Expecting a large discrepancy in rainfall totals,
with the coast getting the least and the higher terrain the
most.

Slightly drier and cooler air filters in Tuesday night, but
cloud cover and gusty west winds will retard any significant
cooling. The actual NW wind shift occurs late Wednesday with a
fine line and possibly some shower activity for the mountains.

Wednesday will be the "nice day" this week with temperatures
warming into the lower 50s north to mid 60s along the coast with
west winds.

Another system will be poised to affect the region beginning
Thursday night through Saturday, with a coastal low deepening
rapidly over the gulf of maine. There are many questions
regarding this system, but there should be enough moisture and
lift for scattered showers with heavier rain a possibility.

Aviation /03z Sunday through Thursday/
Short term...VFR today through Sunday.

Long term... Ifr conditions will be in progress by Monday
morning as easterly flow provides low clouds and light rain or
drizzle for all TAF sites. These conditions likely persist
through Monday night. Showers and MVFR conditions may persist
for hie and leb Tuesday into Wednesday morning withVFR
elsewhere. Late Thursday showers will spread in from the SW so
expect some MVFR conditions by evening.

Marine
Short term... Winds will continue to gust over 25 kt over the
coastal waters tonight with gusts as high as 30 kt this evening
at iosn3. Will raise scas for the outer waters and penobscot bay
for the rest of the night. Will gradually diminish however
during the overnight period. Over the waters, but generally
expect the winds to be decreasing over evening so have opted not
to issue any headlines.

Long term... SCA conditions likely Tuesday morning through
Wednesday morning.

Fire weather
Northwesterly flow in the wake of a cold front will push drier
air into the region overnight. Weak high pressure will crest over
the region on Sunday with mostly clear skies and moderate rh. A
warm front will lift back northwards overnight Sunday into Monday
bringing showers especially in the mountains. A generally wet
pattern sets up for the next week as low pressure aloft spins
pushing multiple rounds of showers through the region.

Gyx watches/warnings/advisories
Me... None.

Nh... None.

Marine... Small craft advisory until 6 am edt Sunday for anz150>152-154.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
