Synopsis
Mountain snow showers will taper off to flurries through this
evening as an upper level system slowly drifts east over the
canadian maritimes. Temps will remain below normal through the
weekend under a cool but drier northwest flow. A warming trend
begins on Sunday as high pressure builds over the northeast.

Temperatures will rise to near normal in the mid 50s by Sunday
and above normal into the 60s early next week with plenty of
sunshine.

Near term through Saturday night
As of 1042 pm edt Friday... Clouds hanging tough... Especially
over vermont and have had to make some minor tweaks to keep
clouds around longer and raise temperatures up a bit. Rest of
forecast remains in good shape.

Previous discussion...

going forecast is on track so little change as unseasonably
cold NW flow continues. Still a chance of some light snow
showers or flurries but moisture will become shallower and with
loss of daytime heating, less convective. Still looking at lots
of clouds, especially in the upslope regions as cold air and the
shallow moisture is trapped by a strong subsidence inversion.

Temp drop tonight will be limited by the cloud cover with lows
in the upper 20s to lower 30s.

On Saturday the NW flow of cold air continues, but with not
quite as cold as today as 925mb temps rise to about -1c. With
with drier air aloft any extensive cloud cover will slide off to
the northeast as high pressure and subsidence builds into the
region. High temps should reach the mid 40s to even a 50 degree
reading near vsf.

Saturday night skies should be clearing everywhere as high
pressure approaches from the great lakes with low temps mainly
in the 20s.

Short term Sunday through Sunday night
As of 125 pm edt Friday... Large deep layer ridge will be in
place over the northern new york and vermont area Sunday and
Sunday night. Mostly clear skies and moderating temperatures are
expected. Although temperatures will still be a bit below
seasonal normals during this period, the weather will be quite
pleasant. Winds will remain nwly on Sunday, perhaps reaching 10
mph or so during the mid-day hours with best pbl mixing.

Long term Monday through Friday
As of 345 pm edt Friday... High pressure ridge will be centered
over the region still Monday morning, then slide eastward Monday
night. Monday should be a nice sunny day with near normal
temperatures. On Tuesday return southerly flow will help to bump
our temperatures above normal, with highs reaching the 60s
areawide, our warmest day for quite some time. From Tuesday
night onward GFS and ECMWF not in very much agreement at all,
leading to lower confidence in the details. Does look like
weather will remain active from mid week onward. Still lots of
model disagreement on the phasing of northern and southern
stream shortwave troughs. GFS continues to show a much slower
solution keeping precipitation over our area through the end of
the period. ECMWF clears things out quicker, giving us a couple
drier days towards the end of the week. Lots of uncertainty this
far out, but overall trend is for temperatures back around
normal and active weather for at least wed.

Aviation 03z Saturday through Wednesday
Through 00z Sunday...VFR conditions are expected through the
period. Ceilings through 12z should be in the 4000 to 6000 foot
range and then clouds will become scattered after 12z and
through the remainder of the period. Winds will become light and
variable by 06z tonight... Then increase from the northwest after
14z but at speeds of 10 knots or less.

Outlook...

Saturday night:VFR. No sig wx.

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.
