Synopsis
Weak high pressure will remain over the area through today only
slowing shifting east tonight. The next system over the eastern
great lakes will lift north into quebec tonight and will send a
front towards the region. An area of showers will slowly cross
new hampshire and western maine on memorial day. Warmer weather
returns by the mid to latter part of the week but with the
chance of showers each day.

Near term until 6 pm this evening
Update... Have adjusted temp and dew point grids to help with fog
coverage this morning. Based on observations it looks to mainly
be confined to the NRN river valleys... And behind the sea breeze
front where temps got a little cooler. High clouds are fairly
absent however... So this should be lift quickly as daytime
heating commences.

Previous discussion... Trapped low level moisture is leading to
some slow developing stratus this morning. A weak S WV trof is
passing overhead and providing just enough lift to couple with
nocturnal cooling to spread those clouds inland. At this point
fog is confined to just rkd... So I do foresee this being a
hazard beyond aviation interests this morning.

Daytime heating will allow the remaining stratus to lift... And
inland especially should see plenty of Sun early. This will
allow for more widespread 70s today. As the day warms up this
will allow some convective showers to get going on the higher
terrain. I do not expect these to be particularly fast
moving... And mainly tied to the terrain... So the pop is mostly
for the mtns.

Short term 6 pm this evening through 6 pm Monday
Ridge departs tonight and allows return flow to set up. Clouds
will increase from the W thru the night as the next low pressure
sends a cold front our way. Appreciable precip looks to hold off
until after 12z. Model guidance is in fair agreement that this
will be fairly well organized as it reaches the ct river
valley... But over time will weaken and wash out as it fights the
ridge to the e. So pop starts high categorical midday... And
trends towards likely by late afternoon over W central me. The
onshore flow... Clouds... And precip will make for another
relatively chilly day. Memorial day is not looking like one to
remember weather-wise.

Long term Monday night through Saturday
The deterministic models remain in decent agreement on the longwave
pattern through late next week. We begin the period with an upper
trough centered over the upper great lakes. The upper trough axis
will gradually shift eastward into the northeast conus... Where it
will remain for the balance of the new work week and into the
upcoming weekend. Temperatures this period should average below
normal as troughing and below normal heights continue to dominate
across new england. In the dailies... Low pressure centered north
of the great lakes will push a slow-moving occluded front across
the region Tuesday and Wednesday with onshore flow and the advancing
baroclinic zone providing a damp start to the first half of the new
work week. Behind this frontal system... The unsettled weather will
continue as an upper trough remains parked across the northeast
conus and a series of associated weak cold fronts or surface troughs
cross the forecast area.

Aviation 09z Sunday through Thursday
Short term... MainlyVFR expected across the area thru Sun night.

In the near term however... Weak flow is keeping low level
moisture more or less in place. Especially behind the sea breeze
front this is allowing some stratus to form. Areas of ifr will
be possible from psm up thru aug and rkd... Though confidence is
low on timing and duration. I cannot rule out an isolated shra
in the higher terrain today... Mainly affecting leb or hie. A
more widespread rainfall looks likely mon... With widespread MVFR
possible as the front moves in from the W thru the day.

Long term...

tue - wed... MVFR in shra with LCL ifr in fog and drizzle.

Thu... Areas of MVFR in -shra.

Marine
Short term... Winds and seas to remain below SCA thresholds thru
sun night. Sly flow ahead of the approaching front Mon may bring
a few seas to near 5 ft outside of the bays.

Long term...

tue - thu... Conditions could approach small craft outside the bays.
