Synopsis
Low pressure moves slowly northeast toward the canadian maritimes
tonight into Saturday as high pressure builds to the west. The
high moves to the south on Sunday into Sunday night, followed by a
cold frontal passage on Monday. High pressure then builds in
through the late week.

Near term until 6 am Saturday morning
The surface low has reformed east of ma. Most rain and snow has come
to an end. Light precipitation will end for most areas except the
eastern sections and then another brief period of scattered
precipitation for parts of ny and ct through the evening and
overnight with some light snow possible in some of the higher
elevations. Snow amounts should be less than an inch. Rainfall
amounts generally around a few tenths of a inch. Winds have
turned wnw for most of the area. Winds will gust around 35-40
mph through tonight due to the strong pressure gradient on the
backside of the low pressure. Highs topping out in the upper 40s
with cool temperatures near or below freezing tomorrow.

Short term 6 am Saturday morning through Saturday night
Winds will continue to gust from 35-40 mph, but stay below wind
advisory criteria, through tomorrow afternoon and then lowering
overnight to 15-20 mph. Winds should be NW through the period.

Temperatures should top out near 50 and again be near freezing
tomorrow night. Should be dry.

Long term Sunday through Friday
High pres will allow for a sunny start to the day on sun. With waa
aloft developing, increasing mid and high clouds can be expected for
the rest of the day. The nbm was used for temps, with readings at or
slightly abv average.

The models show a bit of uncertainty wrt the cold frontal passage on
mon. The front is timed to come thru early mon. The GFS appears to
be slightly faster than the ecmwf. The main challenge ATTM is
whether a wave developing along the front will bring a round of post
frontal pcpn to the area. This could fall as snow if it does occur.

The GFS is more robust with this probability, with the ECMWF keeping
the activity S of the cwa. The gem is a bit closer to the gfs.

Complicating factor is that boundary layer temps may not cool
sufficiently for a complete changeover to snow. A blend of the model
data was used, leaning on a warmer overall soln and little to no
snow, based on the wave uncertainty and temp uncertainty combined.

It looks dry Tue into Thu with a low 1030s high building into the
area. During this time of year, it should lead to some large diurnal
temp swings. The nbm was generally used for temps, although the
numbers were lowered Tue ngt with better radiational cooling
expected.

Probably dry for the rest of Thu thru fri. The models produce some
spotty pcpn in the WAA regime ahead of the next sys. With a dry
airmass in place, the official fcst was kept dry. The nbm was used
for temps, with a warming trend likely.

Aviation 20z Friday through Wednesday
Low pressure intensifies as it moves northeast along the new england
coast and then into the canadian maritimes through Saturday.

Gusty wnw winds through the TAF period. G25-30 kt this afternoon,
with a few gusts to 35 kt at the city terminals will increase to 35-
40 kt at most terminals through the overnight. Winds then only
gradually decrease through the day on Saturday.

Scattered rain showers will continue into this evening, with
conditions remainingVFR. Any showers that linger into the overnight
hours at kswf khpn kbdr kgon could mix with or change to snow, which
would result in reduced visibilities. The timing and coverage of any
snow showers remains to uncertain to include in the tafs.
