Synopsis
Low pressure will develop off the mid atlantic coast today then
intensify as it moves northeast through the gulf of maine Wednesday.

High pressure builds eastward into the region late in the week and
into the weekend with a return southwest flow bringing warmer
temperatures by the weekend.

Near term until 6 pm this evening
630 am... Updated grids to better reflect surface conditions, but
this was mostly minor stuff. A little bit of light snow was
noted in SW me, but vis was barely being affected, and it looks
like its in advance of a weak boundary not far above the
surface, which is moving through ATTM and shutting it down.

Previously... Sfc high builds a little across the region today,
and will help stave off WAA to our west. It'll be mostly cloudy,
but any precip associated with that WAA will likely be limited
to NRN nh and perhaps the ct vly this afternoon, and it will be
light. Highs will range from the low 20s in the mtns, to the
upper 30s near the coast and in SRN nh, as flow shifts to sw.

Short term 6 pm this evening through 6 pm Wednesday
Sfc low will develop S of long island late today and track ne
thru the gulf of me. This low forms as some energy lifts out
the base 500 mb trough to our se. The 00z models have shifted
the track of the sfc a little further south, and this has
shifted highest forecast QPF a little further south as well,
with ws warnings for the SRN tier of nh counties, and advisories
in all the rest of the CWA except the far NRN zones. Expect snow
to break out from west to east this evening through the the
pre dawn. Snow should be lighter at the outset, but will begin
to become moderate to heavy, especially over SRN nh toward
daybreak. Overnight lows will only fall a few degrees off highs
today and generally be in the 15 to 25 range.

The bulk of the snow will fall between 09-21z, arriving earliest
in this range in nh and later in me. There still are some
concerns as far as confidence GOES with the forecast. First is
the wave is stuck in a positively trough, and dynamic forcing is
on the weaker side. However, thermal circulations do produce
quite the frontogenetical forcing in the mid lvls between 12-18z
Wednesday, and this will likely produce a decent band of heavier
snow. The euro puts the core of that band just S and E of the
cwa, and that may leave the heaviest snow out of the cwa, but
the best chc will be in SRN nh, where 6 inches or so is a good
bet at this point. If that bands shifts back to the N and w,
then we may have to upgrade to warnings into coastal me. Also,
the sfc low does begin a surge of intensification as it passes
to our south, and this may bring some heavier snowfall to the
mid-coast. Temps will peak in the mid-upper 20s in the north
and into the low 30s in the south. The mid-coast could see some
readings near 35, and some rain is possible her, but probably
not until after most of the snow has fallen already.

Long term Wednesday night through Monday
The deterministic model solutions remain in decent agreement on
the long wave pattern through the upcoming weekend and into early
next week. Pacific energy breaks down the western CONUS ridge
early in the period and eventually the downstream upper trough
across the eastern conus. This will temporarily cutoff the supply
of arctic air to our region and lead to temperatures rebounding
above normal for much of the upcoming forecast period. However... There
continue to be signs in the models that suggest the western conus
ridge may begin to rebuild towards d+10. So... This next warmup
may be prove to be fleeting in nature. In the dailies... We begin
the period with a upper trough axis draped across the
appalachians that weakens and exits the coast by Thursday. At
the surface... A weak coastal low exits into the maritimes by
early Thursday. A second low develops off the carolina coast
along the trailing cold front and passes well offshore to our
east late Thursday and Thursday night. Rising heights and high
pressure building to our south will introduce well above normal
temperatures into the region for Friday and the upcoming
weekend.

Aviation 12z Tuesday through Saturday
Short term... MVFR CIGS this morning should improve toVFR, but
not by much, today, before conds fall back to ifr in sn late
this evening into Wednesday.

Long term...

wed night... Areas of MVFR in lingering -shsn.

Thu... Sct MVFR in mtn -shsn. W sfc wnd gusting to 25 kt.

Fri... Sct MVFR in mtn -shsn.

Marine
Short term... Still seeing swell generated from the coastal storm
that passed off shore earlier today, despite winds dropping.

Seas would remain in the 5-7 ft range in the open waters this
morning before slowly subsiding this afternoon.

Long term...

thu - fri... Small craft conditions are possible outside the bays.

Sat... Gales are possible... With small crafts for the bays.

Hydrology
All rivers but the kennebec at aug have fallen below flood
stage, but ice jams have frozen into place in some areas, and
rivers need to be monitored as these jams could move without
notice.
