1211 pm est Sat dec 16 2017

Synopsis
High pressure builds into the region today through Sunday. Two
weak waves will move through early next week bringing scattered
snow showers except rain or snow showers over southernmost
areas. It cools down again late in the week as canadian high
pressure builds southeast into the region.

Near term until 6 pm this evening
1210 pm... No real changes with this update, just some fine
tuning of pops clouds associated with upslope in the mountains.

Also adjusted winds a bit to put the timing of the highest
winds to mid-late afternoon.

955 am... Forecast update mainly fine tunes snsh coverage and
snow amts in the mtns today, overall should see and inch or so
in most valley areas with up to 3" in the favored upslope areas.

A few tweaks to sky and temps were made across the entire cwa.

620 am update: skies have cleared over most southern and central
areas while clouds continue in the mountains with scattered
flurries. Have made some adjustments for less cloud cover over
southern areas today. No other changes needed at this time.

Previous discussion:
the early morning area of light snow along the midcoast
associated with a weak trof will exit by morning.

Today will not be as cold ahead of an approaching cold front.

Temperatures may rise into the 30s in southern and coastal
areas while remaining in the 20s elsewhere. Scattered snow
showers will continue in the mountains and foothills with
little or no accumulations expected. Plenty of clouds are
expected elsewhere as a cold front moves through the region
later in the day.

Short term 6 pm this evening through 6 pm Sunday
Tonight - high pressure builds across the region behind the
cold front allowing clearing skies to take place. Colder temps
will arrive with overnight lows in the single numbers and teens.

Sunday will be a mostly sunny day as high pressure crests over
the area. Temps will be mainly in the 20s.

Long term Sunday night through Friday
Zonal flow will be in place through Tuesday evening when shallow
troughing is carved out of the great lakes region, into the
midwestern states, and towards the northeast. A weak trough of
low pressure will bring scattered snow to the region Sunday
night into Monday. On Tuesday a frontal system far removed from
the parent surface low will bring snow and rain chances to the
region through Wednesday morning. Residual snow showers will
continue in the mountains through early Thursday morning.

Thereafter the upper level pattern will calm down once again
with less meridional features... But still fast moving energy
from time to time. Thursday will see brief ridging building in.

A baroclinic leaf will begin forming over the central conus,
heralding the next low pressure system that will affect northern
new england next Friday with scattered showers.

As far as temperatures... Cooler weather continues into Monday
for highs (20s and lower 30s). A brief warming trend begins
Tuesday with SW winds in place... Boosting readings into the mid
to upper 30s north to mid 40s south for highs. Highs in the
mid upper 20s north to mid upper 30s south are forecast on
Wednesday... And will be diminished to the teens north to lower
30s south on Thursday behind a cold front. A warm front
encroaching on the area will bring temperatures up once again on
Friday.

Aviation 17z Saturday through Wednesday
Short term...VFR conditions.

Long term... MainlyVFR Sunday night through Wednesday, although
could we see temporary flight restrictions SW to NE in shsn

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
