956 am edt Mon mar 18 2019

Synopsis
High pressure will build in from the west today through
Tuesday and will gradually shift offshore south of the region
on Wednesday, which will allow for a southwest wind to warm
things up a bit. A cold front will cross the region Thursday
and bring some showers.

Near term until 6 pm this evening
955 am update... Little change to the going forecast at this
hour. Sunny skies and somewhat chilly temps will be the rule
into the afternoon hours.

715am update...

have updated the temperature forecast based on early morning
temperature observations. No other changes were needed at this
time.

Original discussion...

a large upper level trough over the eastern part of north
america will drive the weather today and for the next several
days. A cool and dry northwest flow out of canada will keep
things dry today. Low level westerly winds will allow some
mixing, but temperatures should top out only in the 30s to near
40 in the warmest locations of southeast new hampshire and
coastal southwest maine.

Short term 6 pm this evening through 6 pm Tuesday
Broad high pressure begins to nudge into the area from the west
tonight and we should see winds die off a good deal especially
across new hampshire and the northern valleys. This will allow
good radiational cooling conditions with temperatures dropping
into the single digits in the cold spots... Near zero in the
coldest ones.

Very little mixing expected on Tuesday with high pressure
arriving, so our daily warm up will have to come from sunshine
alone. We should once again top out in the 30s to near 40 in
southern areas.

Long term Tuesday night through Sunday
We may be heading into one of the stronger +pna patterns at 500
mb of the winter as winter winds down. Models still uncertain
what to do with with closed low moving into the pacific coast
mid week, and this will affect the pattern in the extended,
particularly as to how much cold air gets pulled equatorward
out of northern canada late in the week and if it can disrupt
the big ridge over western north america as it moves thru.

Tuesday night should be a cold night, as surface high builds to
our south, and 500 mb ridging builds. This should allow for
good radiational cooling, especially in the mountain areas
where they are still holding on to a 2-3 ft snowpack. Therefore
i have undercut guidance by about 10f or so in the favored spots
for radiational cooling away from the coast in me and in
central NRN nh, and only by a few degrees in other areas. This
bring mins to zero or a little less in some of the spots in the
n, and to 15 to 20 in the s.

Wednesday will see the SW flow start to pick up and should see
warmer temps and mainly sunny skies with highs running fairly
close to normal, generally around 40 in the N to the mid to
upper 40s in the south.

500 mb low deepening to our west will allow ridging to build
Wednesday night into Thursday as surface front approaches from
our west. Should be dry across the CWA most of the night, with
some shsn possible in western zones late Wednesday night.

Better chance for precip will be Thursday, which will likely be
ra or shra in all but the mountains as the front approaches.

00z euro shows sfc low forming along the front to our south,
which could keep precip going into Thursday night.

Colder air begins to move in Friday into Saturday, but models
continue to show this as a quick shot with temps moderating
later in the weekend.

Aviation 14z Monday through Friday
Short term... Should see a mostly clear sky with relatively light
winds Monday and Tuesday as high pressure builds in from the
west.

Long term...VFR Tue thru Wed night, but could see MVFR-ifr late
in the ct valley region. MVFR-ifr expected on thu, and may
linger into Thu night.VFR returning Friday

Marine
Short term... Winds continue to diminish as high pressure builds
in from the west.

Long term... SCA conditions expected late Wed into Thu in sw
flow.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

Near term... Ekster
short term... Kimble
long term... Cempa

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