Synopsis
Canadian high pressure builds south into the region today with
cooler air although a weak weather system passing south of the
region today may spread some light rain and snow to southern
areas before high pressure builds overhead tonight through
early Friday. A series of weather systems will move through the
region beginning late Friday and continuing through the weekend
with mixture of precipitation. Fair weather returns for early
next week.

Near term through today
Falling temps continue this early am, and may see a little surge
in temps this morning, but that will likely be it as clouds
move in across most of the CWA this afternoon. Stalled cold
front will sit over SRN new england today, which will be
spilling clouds northward as weak wave move along it this
afternoon. This will bring some light precip into southern zones
this afternoon as well. Steady precip is expected across the
srn tier of nh counties along the ma border. This could start
as a rain or a mix of snow and rain midday to early afternoon,
but will likely become mainly snow as evap cooling lowers the bl
and sfc temps into the low to mid 30s. Further north, into
sullivan merrimack strafford york counties, could see some
shrasn as well this afternoon, and even a little north would
not be surprised to see a couple shrasn. Given the warm
antecedent conditions, and the dry air in lower levels, any
snow will have trouble accumulating, especially at onset. Think
the best chance to see around inch or snow will be in cheshire
county and hillsborough west of the merrimack vly. Further east
around mht ash and eastward toward the coast, may see a coating
in some spots.

Short term tonight through 6 pm Friday
For the most part, any precip should be ending by 6pm or so, and
skies will clear during the evening as sfc high builds in from
the west. Should see a period of decent rad cooling as winds
become light, especially in the mtns, where lows will drop into
the single digits. Elsewhere, look for lows mostly in the 15-25
range.

Friday will start off mainly sunny, but clouds will begin to
increase from sw-ne during the midday, with ovc expected in the
afternoon. Any precip looks to hold off until the afternoon, as
two weak waves try to move thru 500 mb ridging aloft. Although
weak sfc low does develop to our N late in the day. Dynamically,
these are weak waves, but they do generate a broad area of waa,
so should see some precip moving eventually, but may not be
until late. Will also flow turn onshore out of the se, so this
will warm boundary enough across most of the coastal for rain or
a rain snow mix, with temps here generally in the mid to
upper 30s, not looking for much in accums, if anything, outside
the mountains and foothills late in the day Friday. Could see a
coating to half inch in the north. Best chance for wintry
precip will be Friday night.

Long term Friday night through Wednesday
A developing fast moving west to southwest flow aloft Friday
night will allow a weak short to move across northern new
england with some very light mixed overrunning WAA precipitation.

No accumulations of snow are expected with this system with
possibly some very light icing in the mountains. The system
quickly exits by Saturday morning as a weak short wave ridge
builds over the area on downsloping northwest surface winds
allowing skies to become mostly sunny over most areas. Temps on
Saturday will be rather mild with highs in the 40s most areas
and near 50 over southern nh and southwest me.

Sat night canadian high pressure becomes centered north of maine
in the maritimes and allows cold air to drain south across the
region. Models show this cold air damming setting up nicely by
Sunday morning in advance of the next rapidly approaching waa
pattern that approaches from the southwest. Sunday will be a mixed
ptype event with some light accumulations of snow over southern
and central areas before a changeover to the mixed
precipitation and eventually rain. Over the western mountains
and foothills of maine enough cold air may remain in place for
more significant accumulations of snow to occur before any mix
occurs. This system will also be a fast mover and will exit the
area by later Sunday night.

Early to midweek a more westerly drier flow aloft is expected so
generally fair weather is forecast for the latter periods.

Stayed close to model blend guidance for temps through the
outlook period.

Aviation 08z Thursday through Monday
Short term... MainlyVFR today, with the exception of kmht kpsm,
and maybe kcon, where will see MVFR or ifr restrictions in sn
or a snra mix for several hours this afternoon.VFR expected
into Friday morning, with some flight restrictions, likely
MVFR, possible during the afternoon in shrasn.

Long term... Ifr to lifr conditions possible Friday night in some
mixed light precipitation then improving toVFR Saturday. Snow
and mixed precipitation develops from s-n Sunday lowering
conditions to ifr lifr. Some brief periods of freezing rain is
also a possibility on Sunday. Conditions return toVFR by later
Sunday night and continue through Monday.

Marine
Short term... Will hold onto the SCA for a few more hours for
borderline winds and seas, but should be able to be dropped at
or before its current 13z expiration time. Otherwise should stay
below SCA criteria through Friday.

Long term... Scas likely over the outer waters Friday night and
again Sunday through Monday.

Hydrology
For the most part any surge in river flow due to snow melt is
happening now, and rivers will recede today. Ice jam is still
holding the ct river at north stratford above flood stage, and
another jam is also evident on the warner river at davisville,
but this is holding below flood.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory until 8 am est this morning for anz150-
152-154.
