326 pm edt Wed mar 20 2019

Dry weather continues as we sit under mostly clear skies today.

Clouds will begin to move in and thicken heading into the
overnight hours as an upper level system starts progressing from
the great lakes into the north country. Expect scattered
mountain snow showers and valley rain as the system tracks
through. Precipitation becomes more widespread heading into the
weekend as a strengthen winter system couple potentially bring
widespread accumulating snowfall.

Near term through Thursday night
As of 302 pm edt Wednesday... Dry conditions remain across the
north country as southerly winds will continue to increase
through the evening. Expect warm air advection to hold temps in
the mid 30s through the overnight hours, as our min temps don't
fall much this evening. Clouds increase and thicken during the
overnight hours and we'll see precip start to move into the
region by mid afternoon Thursday. The upper level trough that
brings precip continues to track slower than previous guidance
indicates so I think its going to be mid day before we really
start to see much in the way of precip. Precip type looks to be
highly elevational. Snow levels start out between 1000-1500 feet
but quickly increase to around 2500-3000 feet mid day on
Thursday. Then heading into the evening Thursday night we'll
see them come down to around 1000 feet. So the net result is
that in the valley floors we are looking at mostly rain through
the onset while in the mountains we'll see mostly snow with some
rain mixing in. As we head into Thursday night I think we'll
start to see some accumulation of snow and snow ratios given
the meh soundings to start will likely be in the 8-10:1 range on
0.1-0.4" of liquid. That turns into no accumulation in the
valleys and between 2-4 inches highly dependent on elevation.

The during the overnight hours the upper level trough will pass
energy to a deepening coastal low and thats when we'll start to
see a ramp up in total snow.

Short term Friday through Saturday
As of 325 pm edt Wednesday... Overall very little change in
today's nwp guidance compared to yesterday and overnight as
models are locking into the upcoming pattern nicely. By 12z
Friday morning, surface low pressure will be well established
near long island and will move northeast along the new england
coast through the day before stalling over northern maine Friday
night. Morning snow across the region will transition to a
rain snow mix in the valleys as snow levels briefly rise above
1-2kft, but as the surface to mid- level flow shifts to the
north northwest in the afternoon, strong cold air advection will
quickly transition the entire region back to snow for the
evening commute.

Favorable conditions then continue to appear likely Friday night for
a 12-18 hour period of moderate to heavy upslope snow across the
adirondacks and western slopes of the central northern green
mountains as a secondary trough shifts southwest into the region
consolidating with the initial trough to form a single broad upper
trough over the northeast. At the same time, the surface-700mb low
parks itself over northern maine providing an excellent feed of
moisture and lift on north northwest flow resulting in the potential
for 6-10" mid-slopes and up to a foot or more above 2000 feet.

Beginning the event snow density will be quite high with ratios
generally 8-12:1 through midnight Friday, but expect after
that through Saturday ratios will rise to a general 15-20:1
making for superb skiing riding on Saturday. With all this in
mind, have gone ahead and issued a winter storm watch for
portions of the area. Please see our winter page online for

Snow should be ongoing Saturday morning but will rapidly decrease in
coverage beyond the noon hour as coastal low pressure finally shifts
east and surface high pressure over the central CONUS begins to
filter in from the west.

Long term Saturday night through Wednesday
As of 325 pm edt Wednesday... Aforementioned surface high
pressure over the central us begins to shift east over the mid-
atlantic and northeast Saturday night resulting in a crisp, cool
night Saturday night with temps dropping well below normal into
the teens and lower 20s. Sunny skies will allow for a nice
rebound in temps through Sunday with highs bumping well into the
40s before a cold front looks to drop southward into the
region, cooling things off again for the remainder of the period
and bringing some scattered snow showers to the region Sunday
night through Monday. Temps next week will run a good 5-10
degrees below normal with highs ranging through the 30s and lows
in the teens and single digits.

Aviation 20z Wednesday through Monday
Through 18z Thursday...VFR conditions and light winds will
persist through the forecast period. Light ssw winds of
generally less than 10 kts is expected throughout the day before
switching to sse after 00z. Skies will see mainly scattered
high to mid level clouds slowly increasing and thicken after 00z
and ceilings lower through the evening to around 4000-6000 by
12z Thursday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
