Synopsis
Warm and humid weather is expected tonight right through
Wednesday. A few bouts of showers and thunderstorms will be
likely during this time as well, but no all day washouts are
expected. The first round of thunderstorms may arrive late this
evening or overnight tonight. A cold front is expected to move
across the region Wednesday night or early Thursday and is
expected to bring cooler and drier air into the region.

Near term through tonight
Skies have cleared for all but penobscot bay where the marine
layer continues to hold on. Scattered cumulus is in place across
the remainder of the cwa, but not much convective growth as
morning soundings show a solid capped layer. Another short wave
is currently moving into western new york. Ahead of it a line of
convection is moving across the southern tier of new york. This
convection will move into southern new hampshire after sunset.

With the addition of a trigger, and cooling temps aloft ahead of
the short wave we will see increasing instability, at least
aloft, as we move into the overnight. While shear weakens,
expect there to be some potential for storms to remain severe as
they move into southern nh and have added gusty winds with
thunderstorms for this area.

Short term Monday through Monday night
Monday will be hot and humid as southerly flow pushes the warm
front north of our region. Dewpoints will climb into the low 70s
across the south by mid morning. High temperatures will reach
into the low 90s. The combination of heat and humidity will lead
to the heat index near 95f, and a heat advisory may be needed
for eastern hillsborough and interior rockingham county. The
heat and humidity will also result in a lot of instability,
however convection is less likely on Monday than today as dry
mid levels and a bit of a cap suppresses convection.

Nevertheless any convection which is able to develop has the
potential to be severe. With the moist airmass temperatures will
remain high overnight Monday into Tuesday with fog possible
along the coast.

Long term Tuesday through Saturday
Tuesday should feature mainly fair and warm weather. However,
there are outside chances of showers and thunderstorms across
southernmost zones if a weak short wave trough in some of the
guidance materializes. Showers and thunderstorms are a better
bet on Wednesday as a stronger low pressure system approaches
from the west. Severe thunderstorms will be possible. Cold front
moves through by midday Thursday allowing for much cooler air to
move in for Friday and the weekend.

Aviation 18z Sunday through Friday
Short term...VFR conditions have finally returned to the region
through the evening. After sunset expect a return to the marine
layer along the coast with ifr for rkd pwm and psm. Further
inland the clearing afternoon skies will allow for good
radiative cooling in the mountain valleys and expect hie and leb
to also be impacted by ifr fog through morning. Across southern
new hampshire, thunderstorms may impact all terminals around
dusk keeping ceilings to MVFR. After the showers move through
the residual moisture will help to keep ifr fog into con and
mht overnight. Monday will be hot and humid. Expect fog to lift
around 12z across the interior and 14z along the coast allowing
vfr to return for the day.

Long term... Occasional lower conditions Tuesday through Thursday
in bouts of sct showers and thunderstorms. Some low clouds and
stratus possible at night as the low levels moisten.

Marine
Short term... The fog bank over the gulf of maine will continue
to impact the waters through the start of next week. Expect
visibilities to drop overnight with widespread visibilities of
less than a mile and areas less than one quarter mile possible.

Marine layer will lift slightly by mid-morning allowing
visibility to increase above 3nm for the daytime.

Long term... SCA conditions possible Wednesday night and
Thursday.
