Synopsis
Low pressure off the newfoundland coast will pull away into the
north atlantic today. High pressure to the west of the area will
build into new england Sunday. The high will crest over the
area Monday then exit to the east Tuesday.

Near term through Sunday
922 am update: we noted that sc cld cvr has been slow to return
to the fa east of the mtns as of mid morn, with 12z radiosonde
soundings showing somewhat drier below 700 mb. So we lowered cld
cvr somewhat from the prev fcst for late morn, but believe sc
cld cvr will make a return for this aftn alg with isold to sct
msly rn shwrs and hi trrn sn shwrs. With steep sfc-850mb lapse
rates, there will be sig momentum transfer of stronger winds
from at and just abv 850 mb resulting in wind gusts in the 25 to
30 mph range from midday til late aftn, so we adjusted wind
gusts upwards by 5 to 8 mph in this tm frame. Lastly, we
adjusted fcst hrly temps into the aftn hrs, spcly ovr hi trrn,
with little if any chg to fcst aftn hi temps atm.

Orgnl disc: low pressure along the newfoundland labrador coast
will continue to pull away into the open north atlantic today
and tonight. The region will remain in a cool northwest flow
around the low today. Steep low level lapse rates and a moderate
pressure gradient will cause the wind to pick up out of the
northwest. Gusts of 20 to 25 mph are expected late this morning
and afternoon, but perhaps to 30 to 35 mph across the higher
terrain. There will be a decent cumulus deck around 4-6k ft agl
with isolated showers to develop. The model soundings even have
a tiny bit of mid level CAPE this afternoon. The showers would
most likely take the form of rain. Temperatures this afternoon
will be cool with highs mostly in the 40s. The wind will
diminish this evening and the sky will gradually clear from the
west as high pressure builds toward the region. A rain or snow
showers is possible until around midnight, especially across the
eastern half of the cwa. Lows tonight will mostly be in the
20s, with low to mid 30s along the immediate shoreline.

Short term Sunday night through Monday night
High pressure will build toward the region Sunday, then cross
the region Sunday night through Monday night. Generally expect
partly cloudy mostly clear skies across northern areas Sunday
through Monday night, with mostly clear skies downeast.

Temperatures will be at near normal, to slightly below normal,
levels Sunday. Slightly above normal level temperatures are
expected Monday.

Long term Tuesday through Friday
High pressure will exit to the east Tuesday, with partly sunny
skies north and mostly sunny downeast. Clouds will increase
Tuesday night. Low pressure will then lift toward southern new
england Wednesday, with high pressure ridged to the north.

Mostly cloudy skies along with a chance of rain is expected
Wednesday. The low will track northeast Thursday, though whether
the track is more offshore toward nova scotia or across the
gulf of maine is still uncertain. A track across the gulf of
maine would bring a better chance of rain Thursday,
particularly downeast. A more offshore track would limit rain
potential. Uncertainty persists Friday regarding another
possible low approaching from the west which could keep a chance
of rain showers across the forecast area. Above normal level
temperatures are expected Tuesday. Near normal, to slightly
above normal, level temperatures are expected Wednesday through
Friday.

Aviation 14z Saturday through Wednesday
Near term:VFR today and tonight, but brief high end MVFR
ceilings are possible today and into this evening, especially at
the northern terminals from khul to kfve. A northwest wind will
increase today with gusts of 20-25 knots at the terminals from
around 15z to 23z.

Short term:VFR conditions are expected across the region
Sunday through Tuesday. MVFR conditions are possible Wednesday.

Marine
Near term: the wind and seas will remain below small craft advisory
levels through tonight with mostly long period swell of less
than 5 ft.

Short term: winds seas are expected to remain below small craft
advisory levels Sunday through Monday night.

Hydrology
Aside from the risk of an isolated ice jam forming on one of the
northern rivers no flooding is expected this weekend into early
next week. The ice should finally get flushed out next week with
a significant warmup that will lead to a lot of snowmelt. By
mid-late next week, the rivers will be running high due to
snowmelt, but whether there is any flooding will likely depend
on how much rain falls late in the week. The situation will need
to be closely monitored through the week.
