.SYNOPSIS...
Mostly dry and breezy weather will prevail through Thursday.
High pressure will build in from the north Friday for fair
weather. A frontal zone will provide a focus for clouds and
showers Saturday into Sunday. High pressure builds back into the
region Monday before shifting offshore towards the middle of
next week.

.NEAR TERM /THROUGH TONIGHT/...
Pleasant conditions will continue this afternoon with comfortable
dewpoints and temperatures mostly in the 70s to low 80s. We`ve
had enough low- level moisture/instability for a cumulus field
to develop with occasion mostly skies, but these will dissipate
toward sunset. Still can`t rule out a couple of brief showers
this afternoon, but very dry air aloft and subsidence aloft will
make these hard to come by.

A cold front approaches and moves through tonight and may
produce some showers in the mountains and generally just a
modest and brief increase in cloud cover elsewhere. Low
temperatures will range from the mid 50s to low 60s.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
Behind the front, the airmass will remain warm and dry for
Thursday. Good mixing will bring higher winds down from aloft
with gusts 25-35 mph in the morning and afternoon while also
supporting highs reaching the upper to low-mid 80s. Similar to
today, there will be enough low-level moisture for a cu field to
develop, but I think it will be a bit more sparse that today.
Above the cloud layer, forecast soundings continue to show very
dry air with the subsidence inversion even more pronounced. So I
think showers will struggle even more than today, although
upsloping in the mountains could still result in a few showers
there

The cu field will dissipate around sunset with the loss of
heating, and winds will also start to come down. Quite weather
continues Thursday night with low temperatures in the 50s for
southern areas with 40s possible from the foothills northward.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
The 500 mb flow pattern will turn close to zonal across the northern
tier of the CONUS this weekend into early next week. At the surface,
high pressure will be centered south of Hudson Bay Friday through
the weekend with a west to east frontal zone setting up across the
Great Lakes and Northeast. Moisture from a weak wave crossing the
Ohio Valley will interact with this frontal zone this weekend
bringing chances for showers. Shower chances diminish Sunday into
Monday as high pressure slides over New England. High pressure then
shifts east through mid week leading to an upward trend in
temperatures and humidity.

High pressure centered south of Hudson Bay will extend into the
forecast area Friday providing fair weather. Light northwest flow
will prevail over the area except for a sea breeze developing along
the coast during the afternoon. Highs will range from the 60s north
to upper 70s across the south. High pressure holds over southeast
Canada Saturday while an open wave over the Ohio Valley advects warm
air and moisture northward. This set up will produce a west to east
baroclinic zone with waves of low pressure bringing chances for
showers Saturday into Sunday. Ensembles generally agree that shower
chances will be likely Saturday while amounts will be light with
mean QPF around 0.5 inches. Ensembles then suggest drier air will
work in from the north Sunday that will allow PoPs to decrease into
Sunday night. Mostly cloudy skies and east winds will keep things
cool over the weekend with highs mainly in the 60s.

High pressure slides southeast and crests over the region Monday for
a return to mostly fair weather. This high will then slide offshore
towards mid week with return flow advecting warmer air and moisture
into the region. With little in the way of surface features and
upper level support chances for showers will be low Tuesday into
Wednesday.

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
Short Term...VFR with very low shower chances this afternoon
with occasional BKN060-BKN080. Clouds diminish this evening and
then increase somewhat again tonight as a cold front approaches
and crosses. This may bring a brief period of MVFR ceilings
and/or showers toward HIE. VFR Thursday W/WNW winds gusting as
high as 25 to 30 kt with and maybe a shower or two toward HIE.
These diminish Thursday and evening and night with VFR
prevailing.

Long Term...Mainly VFR Friday into Friday night. More in the way of
clouds and -SHRA are likely Saturday into Sunday with periods of at
least MVFR possible. Drier air works into the region late Sunday
into Monday for a return to VFR.

&&

.MARINE...
Short Term...A tightening pressure gradient will result in
increasing southwest winds across the waters through tonight as
a cold front approaches and crosses by Thursday morning. This
could lead to marginal SCA conditions with seas building up to 5
ft. Winds may continue to gust to around 25 kt at times on
Thursday before diminishing Thursday evening and night.

Long Term...Winds and seas remain below SCA thresholds Friday into
early next week. Light offshore winds will turn onshore Friday. A
front stalling near the waters will bring periods of showers and
steady easterly flow over the weekend.

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...None.
NH...None.
MARINE...Small Craft Advisory until 8 AM EDT Thursday for ANZ150-152.
