area forecast discussion... Updated
national weather service gray me
925 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 /through Tuesday/
924pm update: lowered temperatures based on evening
observations /with a slight downward adjustment required for
overnight lows as a result/ with no other changes needed at
this time.

8pm update: forecast largely in good shape this hour... With some
adjustments to current temps/dewpoints/winds to match evening
observations but not significant changes. Showers continue to
march east with very little flow in their wake /occluded front
remains well upstream... Seen as a fine line over upstate ny/
suggests little in the way of clearing overnight with
fog/stratus expected. Have some concerns that fog could become
locally dense if the mid/upper levels can dry out fast enough.

Lamp guidance is fairly robust with the fog... But does not have
great support from the narre-tl and experimental hrrr-tle. Will
continue mention of fog through the night... But will not include
dense wording at this time based on these trends.

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 /Tuesday night 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 /02z Tuesday through Saturday/
Short term /through Tuesday night/...

summary: an occluded front will push east of the region through
daybreak Tuesday with overnight fog and stratus giving way to
improving flying conditions on Tuesday... Continuing through
Tuesday night.

Restrictions: conditions will continue to deteriorate to
ifr/lifr both in low CIGS and dropping vsbys overnight. Quick
improvement toVFR is expected Tuesday morning and continuing
through Tuesday night.

Winds: light south and southeasterly winds /less than 10kts/
will become light/variable overnight with light /less than
10kts/ northwesterly winds developing for the day on Tuesday
/with afternoon local sea breeze development/ before going
calm/light and variable Tuesday night.

Llws: no llws expected through Tuesday night.

Thunder: no thunder expected through Tuesday night.

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.
