.SYNOPSIS...
Mostly to partly cloudy skies are expected today with a few
showers possible, mainly across southern New Hampshire.
Conditions then become unsettled with widespread showers Tuesday
with fog and drizzle also possible tonight into the first part
of Tuesday. Improving conditions are then expected for the
second half of the week, with perhaps yet another unsettled
Saturday in store.

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

1030 AM Update...Forecast is good shape with only minor changes
to temperatures needed based on trends.

625 AM Update...Little change to going forecast this morning.
Mainly cloudy skies with a few spot showers remains expected
for the next several hours.

Previously...

No significant changes to the forecast for today as guidance
continues to advertise a warm front remaining to our south as
high pressure nudges in from the east. This will set the stage
for a gradual moist overunning pattern with increasing clouds
and also a few showers from time to time, especially across
southern NH. Went with a blend of guidance for highs today.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
Moisture continues to increase tonight as warm front remains to
our south. This will increase the chances for fog and drizzle
tonight right into Tuesday morning.

A cold front or occlusion will approach Tuesday with increasing
chances for showers and perhaps a thunderstorm. Not anticipating
any hydro issues at this time.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
Drier and warmer conditions are then expected Wednesday through
Friday with highs in the 70s to low 80s, but broad troughing
aloft over the Northeast US will allow for a few weak
waves/fronts to cross through. These could each bring low-end
shower chances, but nothing significant or widespread is
expected.

Looking toward next weekend...a frontal boundary may stall near or
just south of the area while models are latching onto an upper-level
wave riding along the boundary to generating some showers. At the
same time, there is a decent signal for high pressure to attempt
build in from the north, which could end up suppressing the
front/upper wave to the south. However, this is not a done deal as
there are still ensemble members that bring rain showers farther
north into the area. Still, it looks like the better potential for
drier weather will be farther to the north and east while southern
areas have the higher chances of showers (30-40%) for next weekend.

&&

.AVIATION /15Z MONDAY THROUGH FRIDAY/...
Short Term...Early morning fog in spots should lift allowing for
VFR conditions. However, increasing low level moisture should
allow for MVFR conditions to develop across southern New
Hampshire this afternoon with MVFR to IFR overspreading the rest
of the area tonight and Tuesday.

Long Term...Precipitation tapers off Tuesday evening into
Tuesday night, but conditions then favor more fog development
which could cause additional restrictions. Mainly VFR Wednesday
through Friday, but there still could be additional low chances
for showers.

&&

.MARINE...
Short Term...Conditions are expected to remain below SCA
thresholds through Tuesday. Areas of dense fog are possible
tonight through Tues morning, with patchy drizzle possible as
well.

Long Term...SCA conditions are not currently expected over the
next week. Weak low pressure and front cross the waters Tuesday
into Tuesday night bringing fog and a chance of showers.
Southwest flow sets up mid to late week with a few additional
weak systems crossing the waters. High pressure may build in
from the north over the weekend, but a front may also stall out
near or just south of the waters going into the weekend.
