Synopsis
A warm front crosses the region this evening, followed by a
weak cold front late Wednesday, bringing more humid conditions
to the area for Wednesday and Thursday. Another cold front
will push southeast through the area Thursday setting off
showers and thunderstorms. High pressure builds in briefly for
Friday, but a large upper level low will position itself over
the region this weekend, providing unsettled conditions.

Near term until 6 am Wednesday morning
640 pm update... Showers continue to progress slowly eastward
across the forecast area early this evening and will continue to
do so. The ct river valley is pretty much done with the rain at
this time. However, the eastward progression of the back edge of
the rainfall will likely slow overnight as low pressure develops
just east of CAPE cod. This should keep the coast wet through a
good portion of the night, except perhaps southern coastal
zones. Otherwise, we do expect fog to fill in overnight as well.

Previously...

showers are pretty much on schedule this afternoon, with first
band weakening as it moves through nh and into me, and second
line of convection behind it moving into WRN new england, which
will cross the CWA between 4 and 10 pm. The second line does
slow a little and SRN part of line is forecast to intensify a
bit as a weak mid level low starts to develop, so not ready to
give up on the chance for a few heavy downpours late this
afternoon into this evening yet, especially across the SRN half
of nh and coastal me. Kept the chc of tsra in there for these
areas given a little added forcing and a thin band of strong
850 mb WAA moving thru. Thunder is less likely but still in the
forecast. The showers may linger for much of the overnight
along the midcoast and in the far ERN inland zones.

Tds will rise in many spots overnight beneath the onshore flow
aloft, so fog is likely, especially on the coastal plain. Lows
overnight will be limited by the tds, and generally range from
the mid 50s to the low 60s.

Short term 6 am Wednesday morning through Wednesday night
We get into bit of a col in the lower to mid levels on wed,
which will likely mean clouds and fog are slow to dissipate in
the morning, but strong Sun should help skies become at least
partly sunny in the afternoon. Weak NE flow will keep the ern
zones and the coast cooler than inland areas and the west, with
highs in the 70s from portland N into the me mts, but rising
into the low 80s across much of nh and inland SW me. A weak wave
in the 500 mb could be enough to set a few showers storms in
the N and W zones late in the day and esecially in the evening.

Any weak frontal boundary associated with that trough will wash
out as it moves into the cwa, and it will likely be mostly
cloudy overnight with lows in the upper 50s to low 60s.

Long term Thursday through Tuesday
For the long term forecast we for the most part stay on the
northern edge of the building subtropical ridge. Several weak
shortwave troughs pass through the flow north of that ridge and
bring renewed chances of showers and storms most days. Part of
the subtropical ridge bubbles up into the canadian prairies
late this week which pushes the hudson bay low southeast into
our area. The result will be more widespread showers and storms
this weekend, especially on Sunday. Once the upper low moves on,
though, we will find ourselves in the subsident flow downstream
of the upper ridge so much nicer weather can be expected.

Although the initial trough axis will be to our east on
Thursday, instability develops over the saint lawrence valley
and northern new england with another shortwave trough sliding
through. Thus expect a chance of showers and thunderstorms
primarily over northern areas on Thursday with instability
possibly aided by the terrain. Wind flow regime is rather weak
so don't expect severe weather, but cannot rule out a stronger
storm or two.

Weak ridging builds in on Friday with our area on the subsident
side of this. Thus expect any convection to be rather limited.

Offshore westerly winds will expand the warmer temperatures to
include the coastal plain of maine where low to mid 80s are
expected. Further south in southern new hampshire highs near 90
are possible.

The hudson bay low starts lumbering down toward our area this
weekend. Models still have some slight timing differences with
the GFS a bit slower than the ecmwf. In either case the forecast
idea is rather consistent that we will see an increasing chance
of showers and thunderstorms as the upper low arrives and
preceding shortwave troughs rotate across. Again not expecting
severe weather, but cannot rule out a stronger storm or two on
Saturday depending on how things evolve.

There's pretty good agreement that Sunday is the day the upper
low swings through the area. With cold core low overhead, any
daytime heating will go fully into low level convection. With
cold temps aloft any showers or low topped thunderstorms will
have the potential for some small hail. Temperatures will be
rather limited by the cold air aloft. GFS a bit slower than the
ecmwf on bringing this colder air in, but for this forecast i
favored the ECMWF temperatures slightly.

Upper low exits to the east on Monday which puts us in the
subsident flow on the back side of the low and ahead of a sharp
upper ridge. Although some instability remains on Monday, expect
the subsident flow to suppress this and just lead to afternoon
stratocumulus more so than showers. Will see the dry weather
last at least a couple days with gradually warming temperatures
as well before the ridge moves east and opens us up for the
parade of troughs again.

Aviation 00z Wednesday through Sunday
Short term... Should see all terminals drop to ifr by this
evening, and eventually lifr around midnight. Light flow will
make improvement slow during Wed morning, but should seeVFR by
afternoon.

Long term... MostlyVFR conditions expected, but afternoon
showers and thunderstorms are possible on Thursday. More
widespread MVFR ceilings and showers and storms are possible on
Saturday and especially Sunday.

Marine
Short term... Could see a few SE gusts of 20-25 kt into early
this evening, but winds will diminish after midnight and stay
below SCA conds through Wed night. Look for widespread fog over
the waters tonight into Wed morning.

Long term... Weak pressure gradient keeps wind flow light over
the gulf of maine for the next several days. A frontal boundary
moves through on Saturday before low pressure drops southeast
out of canada and into the gulf of maine on Sunday. Winds behind
this low will shift to northerly and may provide our best chance
of advisory level conditions.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.
