Overview...

A stalled front brings cooler and unsettled conditions to
northern New England for Saturday, with gradual improvement
likely through the weekend. High pressure moves through early
next week. A building ridge across the northern US brings a
moderating trend through the remainder of the week.

Details...

Like clockwork, a stalled front brings cloudy, cool, and
showery conditions to start the weekend. The best chance for
showers looks to be through the first half of the day on
Saturday, with gradual improvement by late in the day. Temps
look likely to remain confined to the 60s for the most part.
High pressure starts to build in on Sunday, but will build in
from the northeast. This keeps a cooler and still moist easterly
flow ongoing into the area, but with some more sunshine.
Temperatures warm to near 70 across western areas, with enough
instability to create some scattered afternoon shower activity,
especially across the higher terrain.

By Monday the high moves more off the east, setting up more of
a southerly flow across the Northeast and ushering in a warming
trend. Temps warm a little more each day, from the low to mid
70s on Monday, to the 80s by Wednesday. A cold front then
approaches from the west by late in the week, but likely helps
usher in warmer temps for at least Thursday before it crosses
late next week or early next weekend.

Moisture also increases through the week on the southerly flow.
By Wednesday, scattered afternoon showers and thunderstorms
become more likely as the airmass moistens. The best chance for
these will be across the higher terrain, and will continue each
day until the front passes late week.

&&

.AVIATION /04Z FRIDAY THROUGH TUESDAY/...
Short Term...Gusty WNW will subside this evening with mainly VFR
tonight through Friday. Skies will become overcast Friday night with
lowering cigs and -SHRA likely bringing MVFR conditions before
sunrise Saturday morning.

Long Term...MVFR to IFR conditions are possible on Saturday
with showers. Gradual improvement back to VFR is likely by late
Saturday. VFR likely then prevails during the daytime for early
to midweek next week, with nighttime valley fog possible each
night. Marine fog is possible at RKD by midweek as the airmass
moistens. Chances for scattered afternoon showers and storms
increase across interior terminals by Wednesday and continue
through late week.

&&

.MARINE...
Short Term...Gusty WNW winds will subside this evening with winds
turning onshore Friday afternoon through Friday night. Winds and
seas will remain below SCA thresholds through the period.

Long Term...A stalled front sags southward through the weekend,
with high pressure prevailing across the water for early to
midweek next week with fair conditions. A cold front approaches
late in the week, with SCA conditions possible in southwesterly
flow ahead of the front.
