area forecast discussion... Updated
national weather service gray me
503 pm edt Mon may 22 2017

Synopsis
A weak cold front will push east through the region tonight.

High pressure will build over the area on Tuesday and hold over
the region through Wednesday. Low pressure will slowly move
northeast out of the ohio valley Thursday and pass through
southern new england on Friday. Low pressure will shift east
into the maritimes Friday night. High pressure will build over
the area Saturday through Sunday.

Near term /until 8 pm this evening/
5pm update: primary update is to boost pops to categorical in
areas of rain ahead of arriving occluded front. Otherwise...

forecast is in very good shape.

At 18z... A 1004 millibar low was centered north of the great
lakes with an occluded front extending southward through the
eastern great lakes and mid atlantic region. NWS doppler radar
mosaic showed several areas of showers along and ahead of this
frontal boundary and upstream of the forecast area. For
tonight... The frontal boundary will slide eastward and exit the
coastline towards dawn on Tuesday. We'll see a few showers ahead
of this boundary with lingering low clouds along with patchy
drizzle and fog for the balance of the overnight hours.

Short term /8 pm this evening through 6 pm Tuesday/
On Tuesday... The front progresses further offshore with partly
to mostly sunny skies under weak ridging. Highs will be mainly
in the 70s... With a few 60s along the maine coast as the light
synoptic flow turns onshore by afternoon. The weak ridge will
hold Tuesday night with partly cloudy skies as we remain
sandwiched between an offshore baroclinic zone and a second over
quebec province.

Long term /Tuesday night through Monday/
Weak southwest flow aloft will be overhead by mid week as one
large trough dominates much of the eastern and central conus.

Over eastern canada another cyclone will be pushing onshore and
causing flow between the two systems to buckle and eventually
prompt the eastern low to eject northeast.

At the surface a series of weak troughs connected by a baroclinic
zone will stretch from the canadian maritimes towards southern
new england and into the midwest. On Wednesday a coastal storm
will be filling and moving northeast offshore which night will
keep the possibility of showers in the forecast along the coast.

Elsewhere high pressure will be in control and there will be a
break in the precipitation through early Thursday morning before
the next batch of precipitation arrives moving from SW to ne.

Even with a break in the rain, expect cool and damp conditions
with fog and possibly some drizzle at times in onshore flow.

Widespread rain moves in Thursday in associated with the eastern
upper low mentioned above and a surface warm front. This will
prompt heavy showers through Friday with both the eps and gefs
indicating high pwat air and plenty of forcing for ascent
available to wring out over an inch of qpf.

While the weekend will not be a total washout there will be
scattered showers Saturday as a cold front moves through. Broad
low pressure will remain active into next week but the details
get particularly hard to decipher past day 5. However, scattered
showers and below normal temperatures are a safe bet.

Aviation /21z Monday through Saturday/
Short term /through Tuesday night/...VFR conditions
deteriorating to MVFR in -shra then to ifr tonight in fog and
drizzle. Ifr conditions will improve toVFR early Tuesday
morning.

Long term... Deteriorating conditions develop on Thursday in fog
and perhaps drizzle ahead of bona fide ra which arrives later
that day. Ifr/lifr ceilings/vsby Thursday night and Friday.

Marine
Short term /through Tuesday night/... Winds and seas are expected
to remain below small craft through the period.

Long term... Scas may be needed Thursday night and Friday as
seas increase above 5 ft.

Fire weather
Cool and wet conditions are expected tonight with some drying
likely Tuesday and Wednesday before the next low pressure system
brings rain Thursday and Friday.

Tides/coastal flooding
High astronomical tides Thursday night (11.8 ft mllw forecast
for portland), will combine with onshore flow possibly resulting
in minor coastal flooding. Another high tide on Friday night
(12.0 ft mllw forecast) will likely again result in minor
coastal flooding although winds may be offshore by that time.

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

Nh... None.

Marine... None.

Near term... Arnott/schwibs
short term... Schwibs
long term... Hanes

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
