6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

A low pressure system will bring light to moderate snow, warmer
temperatures, and increased clouds to the north country today through
Wednesday. Once the system departs, a noticeable warming trend
will kick off going into the weekend. There will be chances for
some light precipitation during this timeframe as some weak
upper disturbances move through.

Near term through Wednesday
As of 408 am est Tuesday... Previous forecast on track. Minor
adjustments made to temperatures to better capture the warming
trend over the next few hours. Also updated sky and pop grids
based on latest satellite radar trends.

Previous discussion... Have issued a winter weather advisory for
rutland, windsor and orange counties of vermont from noon today
through 1 pm on Wednesday.

Light warm air advection snow is spreading northeastward into
new england in advance of a weakening low over southern
ontario lake huron. Satellite imagery shows mid to upper level
clouds have spread over the entire forecast area ahead of the
system, preventing additional radiational cooling overnight.

Temperatures throughout the forecast area are climbing in the
overnight hours in response to warm air advection and the
insulating cloud cover. The light snow will continue through the
mid morning hours today before tapering off through the early
afternoon as the better forcing aloft moves out of the area. By
mid to late afternoon, a second wave of snow will begin as
heights fall aloft ahead of a shearing upper level trough. This
second wave of snow will have better support in the low to mid
levels provided by a developing coastal low that will track
inside of the 40n 70w benchmark Wednesday. Southern and eastern
vermont will see some influx of atlantic moisture as
southwesterly flow briefly takes on more of a
southerly southeasterly component ahead of the approaching low.

Overall, expect to receive generally 3 to 5 inches of snowfall
out of the system tonight through Wednesday in southern and
eastern vermont. Northern new york and northern vermont will
pick up lighter amounts (generally up to 3 inches) as the best
moisture transport and lift associated with the surface cyclone
will stay further south and east.

As the surface low tracks further northeast up the new england
coast, flow will quickly switch back to westerly and the snow
will end by Wednesday evening.

Short term Wednesday night through Thursday night
As of 408 am est Tuesday... The short-term period will be
relatively quiet across the north country. As surface low
pressure exits across the bay of fundy new brunswick Wednesday
night, a narrow ridge of high pressure is expected to build ewd
across central ny into vt. Will see any lingering snow
showers flurries ending across ERN vt early Wednesday night.

Meanwhile, developing wsw sfc-850mb flow on the NRN periphery of
the sfc ridge may be sufficient to generate a few lake
effect upslope snow showers into SRN st. Lawrence county and
into the NRN adirondacks later Wednesday night into Thursday,
consistent with most of the very high resolution nwp guidance.

Thereafter, another weak northern stream shortwave trough with
limited moisture will track from the northern great lakes
quickly ewd across ny northern new england during Thursday
night. This will bring continued chances for snow showers,
mainly across the NRN adirondacks and NRN green mtns. Maximum
pops during the period are around 40 percent, and any snowfall
accumulation from above mentioned factors will be
minimal... Generally a coating to an inch in spots. Will begin to
see a gradual moderation in temperatures, starting with lows
8-15f Wednesday night, followed by highs in the 23-27f range for
Thursday, and into the upr teens to lower 20s for lows Thursday

Long term Friday through Monday
As of 408 am est Tuesday... The 00z nwp guidance suite continues
with the overall theme of a moderating temperature trend
through the forecast period, with building mid-level heights
across the ERN seaboard. A developing mid- level closed low
across the central plains and associated surface frontal system
will begin to develop during the day Sunday. Based on current
indications, it appears temperatures will moderate into the mid
40s for Saturday Sunday Monday. Sfc warm frontal structure in
vcnty of the region may result in scattered rain showers or a
chance of mixed sleet freezing rain across sheltered valleys of
ern vt during the day Sunday, followed by better surge of south
winds and emergence into the warm sector as sfc low is expected
to pass across the great lakes and through sern ontario late
Sunday night into Monday. Should see a period of moderate
rainfall as trailing cold front sweeps across the region later
Monday into Monday night. Both the 00z GFS and ECMWF are
consistent in overall scenario. Given presence of lingering ice
jams in spots, may see renewed hydro concerns heading into early
next week, though temperatures are not expected to get as warm
and rainfall amts are not expected to be as heavy as what
occurred on Friday 1 12. We'll continue to monitor trends with
the expected warmup and potential moderate precipitation for
Sunday Monday.

Aviation 12z Tuesday through Saturday
Through 12z Wednesday... Widespread MVFR ifr conditions with
light snow will generally improve to MVFR lowVFR conditions as
snow tapers off between 13z and 15z. Next wave of heavier snow
will start at rut around 19z, then spread to mpv btv pbg between
00z and 02z. With this wave of heavier snow, expect low ifr
visibilities through end of TAF period at rut mpv with ifr to
MVFR visibilities at pbg btv. Winds will generally be light
from the south throughout the period.

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 L-36.com 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.
