Area Forecast Discussion
National Weather Service Gray ME
225 PM EST Sat Feb 17 2018

.SYNOPSIS...
High pressure will quickly exit into the maritimes this evening.
Quick moving low pressure will move south and east of New England
tonight and early Sunday, bringing a plowable snow...particularly
over southern New Hampshire and coastal Maine. As we move into
next week...a warming trend is expected with temperatures moving
well above normal...especially Tuesday and Wednesday. Expect
some rain late Monday into Tuesday and again Wednesday
Afternoon.

&&

.NEAR TERM /THROUGH TONIGHT/...
At 19z a 1030 millibar high was centered near the Bay of Fundy.
A weak area of low pressure was over the southeast CONUS while
low pressure was over northern Ontario with a trailing cold
front through the northern plains states. Clouds are on the
increase ahead of these southern and northern stream impulses
as the surface high retreats offshore. The southern stream
impulse will race east while an associated surface low tracks
rapidly east-northeast and just outside the 40N/70W benchmark
late tonight. A surface trough will extend northwest into the
coastal plain and will act as an additional focus for heavier
snowfall. The model trend has been slightly further to the north
and west with QPF and snowfall amounts raised a bit over
southern New Hampshire and along the coastal plain of Maine. The
advisories have been extended further north and east in Maine
with a sharp cutoff in QPF and snowfall amounts as you head
north and west away from the coast. The steadier snow will
spread northeast this evening and taper off in all but our eastern
Maine zones by morning.

&&

.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
Rapid improvement on Sunday as snow exits our eastern Maine
zones by mid morning...with downslope and drier air bringing
clearing to all but mountain sections where upslope will
generate a few lingering clouds and snow showers. Northwest
winds will gust up to 25 mph in the wake of the low as it begins
to rapidly intensify well offshore. Quiet Sunday night as high
pressure builds by to our south. There will be a few late night
warm air advection clouds across northern New Hampshire and
Maine Sunday night where a few flurries will be possible.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
12Z model suite continues to indicate a large and persistent
upper level ridge will develop during the early to midweek
period next week along the east coast. This will lead to very
warm temperatures during the period.

In the dailies, the southwest flow will begin on Monday as warm
air advection develops over a large area in the Northeast. The
airmass will initially remain relatively dry, so there will only
be a low chance for precipitation with this initial batch of
moisture. By Monday night, a warm front will become quasi-
stationary over northern most sections. This will increase the
chance for precipitation, especially in the mountains. Near this
dividing line between very warm, humid air and cold
temperatures, some freezing rain and sleet is possible. Also,
with the increase in low level moisture, expect fog during the
overnight period.

Increased dew points over the cold snowpack may allow for fog to
continue on Tuesday. H8 temperatures reach +10C over southern
areas. Depending on the availability of mixing potential,
temperatures may quickly rise through the 50s, with 60s over
southern areas. There will be a warm start to the day on
Wednesday, with H8 temperatures reaching as warm as +14C at H8.
This will likely be the warmest day in a long time and perhaps
record breaking. Below are the record for Portland and Concord
on Tuesday and Wednesday.

***Records for PWM & CON***
        TUE        WED
PWM     61/1994    59/1953
CON     66/1930    64/1872

Cold air advection will begin Wednesday, but not until the
afternoon hours.

More seasonably cold weather will return for the end of the work
week. High pressure will build in from Canada, however readings
will still be at or above normal for this time of the year.

There remains the potential for another area of low pressure
moving up from the southwest next weekend. This system appears
to be warm as well with possible mixed precipitation.

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
Short Term...VFR deteriorates to MVFR with areas of IFR and
local LIFR vcnty of the coast in snow between 01 and 05Z Sunday.
Conditions improve to VFR throughout Sunday with some lingering
MVFR cigs psb in mtn sections through 22z Sunday.

Long Term...VFR to MVFR conditions will continue into early
Monday. Areas of IFR/LIFR possible Monday Night into Tuesday
night as a warm front approaches and crosses the region
resulting in a period of rain and fog. A cold front will sweep
through the region later on Wednesday with a period of showers
and lower ceilings and visibilities.

&&

.MARINE...
Short Term...Winds will increase tonight from the south as will
seas. On Sunday...northwest winds will generate SCA conditions
behind the departing ocean low. A small craft advisory has been
issued for all waters except Casco Bay for tonight and Sunday.

Long Term...Increased southwesterly winds will allow for SCA
thresholds to continue over much of the waters early to mid week
next week.

&&

.HYDROLOGY...
We will have to monitor the rivers closely next week as the
warm weather and some rain may lead to enough runoff to cause
ice jam flooding. There are several locations with ice jams in
Maine and New Hampshire. Looks like a 72 hour period or longer
with temperatures remaining above freezing. It is possible that
the warmer weather will weaken the ice so that any rise in river
levels will just move the ice harmlessly downriver.
