Marine Weather and Tides
Burlington, VT

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

A cold front dropping southward out of canada will bring a chance of
showers to northern areas this evening through midnight, with high
pressure returning for Thursday and Friday. Unsettled conditions are
expected for the weekend with periods of rain likely, along with the
chance for a few rumbles of thunder.

Near term through Thursday
As of 333 am edt Wednesday... Main weather feature of interest
for the next 36 hours will be a cold front dropping southward
from canada this evening through the overnight hours. Ahead of
the front, mostly sunny and dry conditions are expected for
today with temperatures about 5-10 degrees warmer than yesterday
in the mid 70s to low 80s. Cold front approaches the
international border around sunset with the latest 00z cam
models indicating a little more instability and forcing compared
to previous runs so have bumped up pops into the 30-50% range
across northern areas through midnight. Instability is only on
order of a couple hundred j kg of CAPE through about 02z so
included just a slight chance of thunder along the border
through that time. Otherwise, convective activity fizzles as it
moves south after sunset so central and southern areas will
likely remain dry. There will be a marked increase in sky cover
with the frontal passage which will help to keep overnight temps
milder than the previous night in the mid 40s to mid 50s.

For Thursday, high pressure returns behind the departing front
with northerly flow in the low mid levels keeping temps on the
cool side back in the upper 60s to low 70s despite full

Short term Thursday night through Friday night
As of 333 am edt Wednesday... The Thursday night thru Friday
night period will feature generally tranquil weather as sfc high
pressure builds from sern ontario swrn quebec esewd across
northern new england, and eventually into the canadian maritimes
by Friday aftn into Friday night. Should see good radiational
cooling conditions with light winds and clear skies Thursday
night. Lows generally mid-upr 40s, but would anticipate some upr
30s in the normally colder locations within the NRN adirondack
region and across sheltered locations of far nern vt. Should see
a moderating air mass on Friday as south winds develop around
10 mph. Relatively low humidity levels (2-m dewpoints in the upr
40s to lower 50s) will continue, but high temperatures will be
warmer on Friday, reaching the upr 70s to lower 80s. Will begin
to see some fringe effects of closed 700-500mb low expected
across the ohio valley Friday night. As this system slowly
shifts newd, increasing cloudiness is expected Friday night. The
00z ECMWF suggests associated precipitation remains south and
west of our region Friday night, but the 00z GFS is a bit
quicker to bring potential rain showers into NRN ny after
midnight. At this point, indicated just 20-30 pops for franklin
ny and st. Lawrence counties during the pre-dawn period
Saturday. The increasing cloud cover will result in milder
overnight temperatures, with pre-dawn lows mainly in the 50s,
except near 60f for the st. Lawrence valley.

Long term Saturday through Tuesday
As of 333 am edt Wednesday... Both the 00z ECMWF gfs suggest
unsettled weather this weekend as mid- level low over the ohio
valley is forecast to become an open wave and lift newd across
ny state on Saturday, and eventually across NRN new england for
Saturday night. A second mid-level trough in nwly flow moves
across the north country late Sunday into early Monday, with the
potential for additional scattered showers. Precipitable water
values will be moderately high but not excessive. Unlike the 2"+
pw experienced this past Monday, will see values 1.5-1.7" in
advance of the ohio valley system for Saturday. Overall, present
indications suggest cloudiness and weak mid-level lapse rates
will keep instability low (sbcape < 1000 j kg). Anticipate
widespread showers Saturday, and included a chance of embedded
thunderstorms west of the green mtns, including the champlain
valley and all of NRN ny (slight chance TSTM east of the green
mtns). Severe storms not currently expected. Highs on Saturday
mainly in the 70s. Maintained 60-80 pops for Saturday night with
lows in the upr 50s to lower 60s. May see a break in the shower
activity on Sunday - especially during the morning hrs - but
with trailing shortwave trough approaching from sern ontario,
should see another period of widespread showers late Sunday into
Sunday night early Monday. Gradual clearing is anticipated
Monday night into Tuesday. Highs on Monday only in the lower
70s, but increased prospects for sunshine should result in highs
in the 75-80f range for valley locations on Tuesday.

Aviation 12z Wednesday through Sunday
Through 12z Thursday... Lingering ifr fog at kmpv and kslk
will lift within the hour with conditions largelyVFR through
the period. Scattered cirrus and perhaps a few fair weather
cumulus will stream across the region through the day before a
low mid level deck increases from the north from late afternoon
onward as a cold front approaches. Could see a few showers
along the international border to the adirondacks and central
vermont from sunset through midnight, with brief reductions in
vsby possible. Any shower activity wanes after midnight with a
slow clearing occurring from north to south towards sunrise.


Thursday:VFR. No sig wx.

Thursday night:VFR. No sig wx.

Friday:VFR. No sig wx.

Friday night:VFR. Slight chance shra.

Saturday:VFR. Likely shra, chance tsra.

Saturday night: MVFR ifr conditions possible. Likely shra.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
