Synopsis
High pressure slides across the area today, making a chilly
morning into another chilly afternoon. That high will hold off
the coast but allow return flow and warmer weather to move into
the area Friday into Saturday. With that comes a chance for
precipitation, though not a widespread event. Rain and snow
showers cross the area Saturday and give way to more high
pressure for the weekend. Something to keep an eye on for early
next week will be low pressure developing south of the gulf of
maine on Monday as it moves northeast into the canadian
maritimes.

Near term through today
Weakening 500 mb closed passes to our south today, with strong
ridging just to the north. This system will push some mid-high
level clouds into SRN and western zones today, but the strong
ridging help keep a lot of Sun in the NRN and eastern part of
the cwa. Mostly cloudy areas will probably be limited to areas
south of kleb-kpsm line, with partly to mostly sunny elsewhere.

Light winds through the column expected as we sit beneath mid-
lvl ridging, and a col at 500 mb, so mixing will be limited and
highs will range from the low to mid 20s in the N to around 30
in the south, where the overcast will also help limit maxes.

Short term tonight through Friday
Sfc high pushes to our east tonight, and will generally see a
fair amount of cirrus and increasing SW on the boundary lyr.

This will make for a milder night than we have seen recently,
but still cold, with with lows from around 10 in the N to around
20 in the south. There's some signs of coastal stratus
developing, given, the increasing moisture above the pbl, but
air mass still on the dry side, so not buying in yet.

On Friday, two approaching systems, one to our NW and one to our
sw will spread clouds into the CWA over the course of the day.

Some morning Sun is expected, at least partly sunny skies, but
it will become cloudy during the afternoon cross the cwa. Sw
flow will also help pump warmer air into the region and highs
will be low 30s to around 40.

Long term Friday night through Wednesday after a cold and
quiet stretch of wx... It looks like the forecast area will
return to a more active pattern in the extended.

To start the period a S WV trof shearing off the NE will cross
the area. At this time it looks like a pretty standard frontal
passage... With a band of rain and snow showers. There is a
chance that some higher moisture brushes SRN zones... And that is
where I have the highest pop qpf.

More interesting perhaps will be the evolution of closed low
lifting out of the SRN plains. Lingering baroclinic zone will be
draped to the S of the forecast area... And NRN stream S wv
trofing will be approaching from the nw. This allows low
pressure to rapidly reintensify S of new england. Just how far
n it tracks and how far NW it throws precip remains uncertain.

Ensemble variance points towards upper low evolution in the next
24 to 36 hours being critical to the downstream results. For
instance... A slower upper low on the ECMWF eps helps the surface
low develop farther N downstream later in the run. Those will be
the type of trends to watch in the next couple of days from
observations and guidance.

After Tue high pressure returns to close out the week... But deep
return flow follows ahead of the next trof. Our next chance for
widespread precip will be around the weekend as a result.

Aviation 07z Thursday through Monday
Short term... MainlyVFR through Friday. There is a low chc for
some coastal stratus tonight.

Long term... As a front crosses the area Sat some areas of MVFR
are possible in lowering CIGS and shra. High pressure andVFR
conditions hold into mon. Will have to watch for low pressure
developing along the coast to spread precip into the coastal
terminals Mon into tue... But that is a low confidence forecast
at this range.

Marine
Short term... The waters remain quiet today thru Friday.

Long term... Low-end SCA conditions possible on the ocean waters
Friday night into Saturday in association with low pressure
moving by to our south.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
