Synopsis
The wind will die down tonight as high pressure builds in from
the west through Wednesday. The next low pressure system will
track through southern canada and across northern maine Thursday
night bringing our next chance of rainfall in new england. After
a brief break on Friday into Saturday, another low will bring
more rain chances Saturday afternoon and evening.

Near term until 6 am Wednesday morning
630 pm... Made some adjustments to pops, just extend the shower
activity thru dusk, with mostly sprinkles or light brief showers
outside the mtns. Winds will gradually diminish but will likely
remain gusty through 00-01z.

Previously... Northwest flow regime continues on the back side
of low pressure tracking through the gulf of saint lawrence and
the canadian maritimes. The pressure gradient between this low
and high pressure over the great lakes combined with cold air
advection is what has provided the strong wind gusts today.

Expect these winds to continue for a few more hours into the
evening but should be on the decrease going into the night as
the high pressure axis shifts toward the area. Afternoon cumulus
and stratocumulus in the mountains will also be decreasing this
evening and overnight along with the showers. Expect
temperatures to drop into the 40s for most areas, though north
of the mountains it could drop into the 30s. Went a little above
guidance for lows in northern areas due to the expected cloud
cover and remaining winds.

Short term 6 am Wednesday morning through Wednesday night
High pressure builds in from the west on Wednesday. Expect north
winds to initially be gusty especially in eastern areas but will
diminish as the day GOES on. In fact we will probably even see a
sea breeze along the coast, but especially the new hampshire
coast where the northerly flow will not counteract it.

Temperatures will warm into the 60s to low 70s under mostly
sunny conditions.

Surface high pressure axis shifts east across the area Wednesday
night. This will bring a period of light to calm winds and
pretty good radiational cooling conditions. However, cloud cover
is expected to begin spilling over the top of an upper level
ridge and will limit the cooling potential especially in the
west. There's a chance we could see some frosty conditions in
the northern valleys. We will need to keep an eye on this for
any potential need for a frost advisory.

Long term Thursday through Tuesday
Pattern remains active in the extended... But at least this time
it comes with seasonable to above normal temps. Overall
expecting frequent trof passages with chances for showers or
storms.

One window of note will be Thu night. Model forecasts do show
decent mid level lapse rates moving in ahead of a S WV trof
diving sewd thru the great lakes. Warm front will struggle to
advance into NRN new england... So I expect a strong inversion to
set up aloft in the WAA regime. At best it seems like a chance
for thunderstorms is probable in the evening and overnight. At
worst some models guidance have very steep lapse rates and
potential for hail with the stronger storms. For now I will
bring chance likely thunder to the forecast for the Thu night
period.

Another window to watch will be the late weekend with the next
trof passage. Another potential for thunder as a plume of
steeper lapse rates tries to edge into the region. At this range
i will keep wording to chance.

Aviation 00z Wednesday through Sunday
Short term... Gusty northwest winds diminish this evening. They
will gust about half as strong on Wednesday especially in
eastern areas before dying off altogether Wednesday night.

Expect afternoon cumulus and stratocumulus to dissipate this
evening and all areas should beVFR through Wednesday night.

Long term... High pressure early Thu gives way to approaching
s WV trof. Increasing chances for shra and tsra Thu night.

Overall expectVFR conditions... But local ifr is possible in
heaviest shra tsra. Tsra also looks possible most of the night
before front comes thru. High pressure returns Fri thru Sat with
vfr conditions.

Marine
Short term... Offshore northwest winds will remain gusty this
evening. There could be an occasional gust to near gale force,
but predominantly they should gust in the 30 kt range. Winds
begin to diminish this evening, so the bays will likely see the
gusts fall below advisory levels around midnight. The outer
waters may hang on to the gusts until Wednesday morning. As high
pressure axis crosses the area on Wednesday expect a sea breeze
circulation to develop.

Long term... Sw flow ahead of the next trof will bring winds and
seas to just below SCA thresholds. Will have to watch winds
turning nly behind departing system for a few gusts to sca
thresholds fri. High pressure in control into Sat with winds
and seas below sca.

Gyx watches warnings advisories
Me... None.

Nh... None.

Small craft advisory until 6 am edt Wednesday for anz150-152-
