Synopsis
Low pressure off the new england coast will move east into the
maritimes today as another area of low pressure approaches from
the west. Low pressure will move east through southern quebec
tonight and will continue east through northern maine and into
the maritimes on Wednesday. High pressure will build in from the
west Wednesday night and will shift offshore on Thursday. A cold
front will approach from the west Thursday night and will move
east through the region on Friday. Cyclonic flow will persist
over the region behind the front Friday night and Saturday.

Near term until 6 pm this evening
Models seem to be doing a good job handling bands associated
with the low shifting to our S and E this morning, as well as
some waves of showers moving around the low. The band that's
lined up along the ct vly at 07z should weaken over the next few
hours,. With another weaker band developing across the me mtns
between 9 and 12z. None of the precip is performing as
efficiently as it did in SRN areas last evening, so overall
will likely not add significant to river flow, but it still need
to be watched this morning. The showers should diminish over nh
during the first part of the morning, with some breaks of sun
possible this afternoon. In me, the showers look to end late
morning to midday, but will likely stay cloudy thru the
afternoon with n-ne flow persisting. Highs range from the mid-
uppr 40s in the ERN zones, thanks to that NE flow, to the low to
mid 60s in SRN nh and the ct vly.

Short term 6 pm this evening through 6 pm Wednesday
Just as we say goodbye to one system, another moves in tonight.

This one will be fast moving, with generally light qpf. Precip
will arrive in nh this evening, and into SW toward midnight,
crossing into the rest of me midnight or shortly thereafter.

This will be more showery, but could see a few hours of steadier
light rain overnight. Lows will range from the upper 30s in the
me mtns, to 40-45 across most of the rest of the cwa.

The weak fast moving sfc low should be exiting the gulf of me
wed morning, and this will likely bring shra to an end across
the SRN zones in the morning. The 500 mb low crossed SRN quebec
and moves into the crown of me during the afternoon, and so the
nrn zones will see a chc of showers thru the afternoon. Highs
range from the upper 40s in the N to 55-60 in the south. Should
see some clearing in the south as wind shift to the west there
in the afternoon, but winds stay lighter closer to the low
aloft in the north, and it will be tough to clear until that
moves out Wed night.

Long term Wednesday night through Monday
Low pressure will shift east into the maritimes Wednesday night as
weak high pressure builds in from the west. Will see a fair amount
of cloudiness through the evening along with a few stray showers.

Looking for at least partial clearing after midnight as the upper
trough pushes east. Low temperatures will generally range through
the 30s to near 40.

Weak high pressure will crest over the region on Thursday before
shifting offshore. Should see a mix of Sun and clouds during the
day as warmer air makes its way back into the region on return
flow. High temperatures will range through the 50s north and lower
to mid 60s south.

Next shortwave in a fairly active pattern will be on the way into
the region Thursday night. After a mostly clear evening... Expect
increasing clouds after midnight and a chance of showers in
western zones by daybreak Friday. Low temperatures will range
from the mid 30s north to the mid 40s south.

Cold front will approach from the west Friday and will push into
the region in the afternoon. Looking for rain through the day but
models begin to diverge on amounts at this point. GFS keeps the
frontal system more progressive and moves system east Friday night
while the ECMWF slows the front over the area as low pressure
tracks north along it. This results in substantially more
rainfall Friday night through Saturday which may result in more
flooding on area rivers.

Model differences continue through the remainder of the weekend
and into next week so will be sticking close to sb numbers for
later periods of the forecast.

Aviation 07z Tuesday through Saturday
Short term... Fairly dry air has kept most terminals eitherVFR
or MVFR tonight, but persistent rain fall will moisten up some
places so that some fog and ifr CIGS develop for a few hours
around sunrise. Should see a brief improvement this afternoon,
toVFR ins some spots, but at least MVFR, before the next
system moves in and brings things down to ifr this evening. That
will linger into Wed morning, with improvement toVFR expected
wed afternoon.

Long term...

becomingVFR Wednesday night.VFR Thursday and Thursday night.

MVFR ifr ceilings developing Friday... Improving toVFR Friday
night with areas of MVFR ceilings in the mountains.VFR
Saturday.

Marine
Short term... Will hold SCA as is for today, but this afternoon
winds will start to diminish. Will likely to convert SCA to haz
seas for the overnight, as seas stay high.

Long term...

sca's likely late Friday night into Saturday.

Hydrology
Rivers will remain high through the week with additional
snowmelt and several chances for rain. We will have to monitor
this situation closely, as it would not take too much rain to
cause the rivers to rise again. It does look like heaviest rain
from the current system is over and rain will down during this
morning. Another weak system passes tonight, but that is fast
moving and will have limited qpf. Will also have to watch for
the chance of more significant rainfall fri-sat as some
deterministic guidance and ensemble members suggest.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory until 6 pm edt this evening for anz150-
152-154.
