Synopsis
Weak high pressure will build across northern new england today
allowing for mostly sunny skies and dry weather. Tuesday will
feature more clouds, but just a chance of showers, mainly over
southernmost new hampshire. Chances for rain increase mid to
late week, especially Thursday night and Friday as low pressure
develops to our southwest and moves northeastward. At this time
it looks like the low will move away for the weekend allowing
for a return to fair weather.

Near term until 6 pm this evening
530 am update... Just a quick update to better capture the
locations of valley fog (western zones) early this morning.

Otherwise, no changes to the latest forecast.

Previously...

cold front has pushed offshore as of 0630z and clearing
continues to take place in its wake. The exception is valley fog
where the low levels have decoupled but that will lift early on
this morning once mixing commences. Overall, a mostly sunny day
will be had with near normal temperatures. A seabreeze is
likely to develop on the coast this afternoon which will knock
back temperatures a bit.

Short term 6 pm this evening through 6 pm Tuesday
Weak high pressure will continue to dominate the weather map
over northern new england tonight with fair weather expected.

Some clouds are likely to increase late across the south as a
weak warm air advection pattern gets going.

Tuesday should be a fair weather day for the vast majority of
the forecast area as the main baroclinic zone remains over
southernmost new england. A short wave trough is expected to
ride eastward along this zone Tuesday, and may spread a few
showers across southern nh. Otherwise, mostly cloudy skies are
expected.

Long term Tuesday night through Sunday
It's sort of been a theme for several weeks now that the weather
is mostly cloudy and frequently rainy but we manage to get some
nice weekends especially Saturdays. This is the case again this
week as we'll be cloudy, cool, and occasionally rainy this week
before things clear out for the weekend.

Frontal boundary remains stalled south of new england Tuesday
night and Wednesday with a couple of weak waves of low pressure
tracking along the boundary. For the most part shower activity
should stay south over southern new england, but if any of these
waves gets a bit more organized it could send some precip into
southern parts of the forecast area. Either way expect it to
remain cloudy with an onshore east to southeast wind keeping it
cool especially near the coast. Meanwhile, another front shifts
into the northern part of the forecast area on Wednesday being
pushed along by an upper low spinning through quebec. This could
trigger some showers in the afternoon and evening especially in
northern areas.

Low pressure develops over the great plains and tracks through
the ohio valley southern great lakes around midweek. This will
be our more substantial rain maker as it moves into our area
Thursday into Friday. Some timing differences still exist
between the various models which create some uncertainty with
the precipitation chances for each period of the forecast,
though the overall idea of a rain event in the Thursday to
Friday time period is widely agreed upon. The cmc GFS track
the low through our area Thursday evening and bring drier
weather by Friday morning. Meanwhile, the ECMWF is about 12
hours later making Friday the rainy day. With the slower and
deeper solution, the ECMWF also gets a better tap of moisture
and drops a widespread 1 to 3 inches across our area. If this
were to occur it could cause some minor flooding.

Behind this low expect a better clearing to finally arrive as
our area will be in the subsident flow behind the departing
upper trough and ahead of a developing upper ridge over the
great lakes. Thus expect a dry northwest flow out of canada with
warmer temperatures and a lot more sunshine this weekend,
possibly as early as Friday depending on how quickly the low
gets out of here.

Aviation 10z Monday through Friday
Short term... Local ifr conditions in fog are expected through
about 11z this morning. Thereafter, all areas will beVFR today
and tonight. A seabreeze is expected to develop at coastal
terminals this afternoon. Local MVFR conditions are possible
across southern nh on Tuesday in scattered showers.

Long term... It will be mostly cloudy this week with ceilings
varying fromVFR down to ifr at times especially as an onshore
southeast flow develops Tuesday into Wednesday. Low pressure
arriving from the west will bring a widespread rainfall with
more widespread ifr conditions likely Thursday into Friday.

Clearing finally expected behind this low Friday through the
weekend.

Marine
Short term... Winds and seas will remain below SCA thresholds
through Tuesday.

Long term... Light onshore east to southeast flow expected
through Thursday. Low pressure moving out of the great lakes or
ohio valley will track toward the gulf of maine Thursday night
into Friday. This will be a stronger, more organized low
pressure system and could bring some stronger wind speeds to the
gulf of maine, though it will depend on the track of the low.

Generally expect advisory level winds to be possible Thursday
into Friday but confidence is low on timing.

Gyx watches warnings advisories

Nh... None.
