area forecast discussion... Updated
national weather service gray me
735 pm edt Thu jun 20 2019

Synopsis
We'll see locally heavy rainfall and cool temperatures through
tonight as low pressure tracks gradually east across the area.

By Friday... The low will exit the coast will slow improvement as
we head through the day with precipitation ending even in
coastal sections during the afternoon. Gusty northwest winds
develop by late tomorrow then continue through the weekend as
the low lingers over the maritimes. A few pop up showers are
likely on Saturday... Otherwise a dry weekend is expected. A
ridge of high pressure and dry air builds across the area for
late in the weekend and early next week.

Near term through Friday
608 pm update: showers have lifted north over southern nh and
far SW maine and have adjusted pops to focus heaviest rain over
the next few hours over northern areas. More showers closer to
surface low will arrive from the west later this evening.

Issued a dense fog advisory for coastal areas as vsbys drop yet
again this evening. However... Flow will turn northern overnight
and should bring any fog to an end before daybreak Friday.

Otherwise... Lowered near term temperatures to match recent
observations with no major changes to overnight forecast lows.

Previous discussion below...

shortwave impulse noted on radar mosaic animation as well as
goes water vapor imagery over northeastern new york at moment.

A nearly stationary surface boundary remains situated from
northeast new york across southeast quebec. It appears that
heaviest rainfall and localized flooding potential with this
first impulse may be confined to northern new hampshire and
western maine mountains through early evening. Behind this
feature... Lighter showers for much of the overnight. Then next
impulse sweeps east and brings a second round of steadier
precipitation late tonight with heaviest QPF well south of the
first round.

Short term Friday night
Friday starts rainy as the second impulse crosses the area along
with an associated surface low. Steadier precipitation tapers by
afternoon even in coastal sections as the low and upper support
slide offshore. A gusty northwest flow develops behind the
surface low bringing somewhat drier air into the region. Winds
switch to an offshore direction which will allow us to warm into
the 60s and lower 70s. A few lingering mountain clouds and stray
showers Friday night... Otherwise mainly clear with patchy valley
fog developing. Lows mainly in the 50s.

Long term Saturday through Thursday
A strong northwesterly gradient will prevail across the region
through the weekend as high pressure slowly builds in from the
west. Should see a fair amount cloudiness on Saturday as cold
pool aloft results in steep lapse rates and perhaps a few
scattered showers in the afternoon. Highs on Saturday will
range from the upper 60s north to the mid 70s south.

Temperatures will moderate aloft and clouds will diminish
somewhat Saturday night as brisk northwest flow continues.

Lows overnight will range through the 50s. Sunday will feature
a little more in the way of Sun as gusty northwest winds
continues across the region. Sun and downsloping winds will
boost temps in southern zones into the lower to mid 80s and
mid 70s to near 80 in the north.

High pressure will continue to build in from the west Sunday
night and will crest over the region by Monday morning. Looking
for mostly clear skies overnight and light winds. Lows will
once again range through the 50s. High pressure will gradually
shift east on Monday. Looking for a mostly sunny day with highs
similar to Sundays ranging from the mid 70s north to the mid
80s south.

High pressure will continue to slide off to the east Monday
night as a warm front approaches from the west. Expect
increasing clouds during the evening hours and a chance of
showers after midnight in western zones. Lows will range from
the lower 50s north to the lower 60s south.

Occlusion will quickly catch up with the warm front over the
region on Tuesday as this boundary pushes east through the
region. Looking for showers and possibly some embedded thunder
as this boundary takes most of the day to push through.

High temps will range through the 70s.

Frontal boundary will push east of the region Tuesday evening
with clearing from west to east. Lows will range from the mid
50s north to the lower 60s south. Wednesday looking sunny and
warm with highs in the 70s to lower 80s.
