Synopsis
Behind a departing low pressure system, a northwesterly flow
will introduce cooler and drier air into the region today. High
pressure will build into the region for Thursday. Low pressure
will then approach the region for late Friday into Saturday
with snow and mixed precipitation likely for the region.

Canadian high pressure will then build into the region on
Sunday.

Near term /through today/
As of 3am, very damp and foggy conditions across maine and new
hampshire. Temperatures are in the mid 30s across the region
with dewpoints similar. With most of the region still covered in
snow this relatively warmer air has resulted in patches of dense
fog. This fog will dissipate in the early morning with the
morning Sun and developing drier flow.

A low center moving northeast through the gulf of maine today
will bring showers to coastal maine and new hampshire through
mid morning. As the rain departs northwesterly flow will develop
brining drier conditions. Clouds will slowly clear in the south.

In the mountains a few upslope showers will develop.

Short term /tonight through 6 pm Thursday/
High pressure will build in for tonight and Thursday. High
temperatures will return to the mid 40s south to upper 30s north
with mostly sunny skies and light winds.

Long term /Thursday night through Tuesday/
Still some uncertainty with upcoming storm system at the end of
this week in terms of snowfall projections.

Canadian high pressure will remain entrenched over the forecast
area on Thursday. It will gradually retreat to the north and
east on Friday as low pressure exits the ohio valley.

00z operational model suite and ensemble members are in better
agreement tonight bringing low pressure to the new jersey
coastline Friday night where it will undergo only some modest
intensification. Nevertheless, prolonged period of northeast
flow and warm air advection pattern aloft may very well allow
for steady precipitation Friday into Saturday. Model QPF does
vary however with the euro being the wettest at this time.

Boundary layer temperatures may be an issue over southern areas
are they often are in the late march and early april time
frame. Used ptpye from wet bulb for the initial portion of the
forecast. As the system departs on its easterly track late
Saturday, a plowable snowfall is possible, mainly over interior
locations away from the shoreline.

Canadian high pressure will then reassert itself on Sunday as
more cold air and near or slightly below normal temperatures
advect into the region. This sets the stage for another possible
repeat with low pressure passing by to our south during the
middle of next week. Temperatures initially look a little warmer
for this second event.

Aviation /07z Wednesday through Sunday/
Short term... Smorgasbord of flight categories across the
region this morning. Generally MVFR through new hampshire and
towards the northwest of maine. Meanwhile the coastal plain has
lifr ceilings with some patchy dense fog, except in the rain
showers where visibility briefly improves. The low bringing all
this moisture will move off shore today and expect conditions to
improve to MVFR region wide by mid morning. Conditions will
continue to improve into Thursday with just a chance for MVFR
ceilings in snow showers near the international border.

Long term... Ifr conditions developing Friday with area of lifr
over southern areas possible. These conditions will continue
into Saturday as low pressure passes by to our south. Conditions
improve toVFR on Sunday.

Marine
Short term... Generally calm waters currently. Expect winds to
pick up this afternoon under northwesterly flow as the current
low departs. A small craft advisory has been issued beginning
late this afternoon and extending through the overnight hours.

There isn't really an upper level jet to mix down any strong
winds but cold advection should be enough to reach SCA even in
the bays.

Long term... SCA conditions may occur Friday night into Saturday
as low pressure passes by to our south. SCA conditions possible
once again midweek, next week as yet another area of low
pressure passes by to our south.

Tides/coastal flooding
A very high astronomical tide will occur early Friday morning
with 11.1' expected in portland at around 06z. Onshore winds and
seas will just be beginning to develop at this time. Northeast
flow will be more pronounced during the Saturday afternoon high
tide which is lower at 10.3'. Expect about a 0.5 to 1.0 storm
surge at that time which would bring the storm tide to around
11.0 feet or so. With waves running 5 feet or so at the time,
splash-over nomograms suggest to only expect little in the way
of issues along the coastline.

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

Nh... None.

Marine... Small craft advisory from 5 pm this afternoon to 8 pm edt
Thursday for anz150>154.
