Marine Weather and Tides
Plattsburgh, NY

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.

344 pm edt Sun may 20 2018

After a cold front finishes crossing the region this afternoon, high
pressure quickly builds back in tonight and Monday with clear skies
and warm temperatures. Showers chances will return on Tuesday and
continue into Wednesday with a couple of fronts crossing the region.

Thereafter, high pressure and dry weather will take hold through the
end of the week along with mild temperatures.

Near term through Monday night
As of 329 pm edt Sunday... A cold front continues to slowly push
southeast across the north country this afternoon, with much
drier air following it its wake. Hence expect the pesky cloud
cover will eventually dissipate as we head through the early
evening hours. High pressure will build into the region behind
the front, leading to clear skies and light winds. This will
allow for radiational cooling overnight; low temperatures will
mainly be in the lower to mid 40s, but mid upper 30s will be
likely in the usual cold locations in the adirondacks and
northeast kingdom. While widespread frost is not expected, some
patchy frost will be possible in sheltered locations. Monday
will be a fantastic day with lots of sunshine and highs in the
lower to mid 70s. West to northwest winds will pick up just a
bit once we see daytime mixing with some gusts reaching 20 mph
during the afternoon. Clouds will increase from west to east
Monday night ahead of low pressure sliding across the great
lakes. Rain will begin to spread into our western areas toward
daybreak Tuesday. Overnight lows in the upper 40s to mid 50s are

Short term Tuesday through Tuesday night
As of 329 pm edt Sunday... Trends for Tuesday amongst
short medium range guidance have been towards wetter and cooler
conditions with a frontal zone draped across the region a weak
shortwave trough moving through during the afternoon and evening
hours. NAM is the most aggressive with QPF owing to a stronger
surface low pulling out of the ohio valley, while the remaining
guidance including GFS offer a weaker low, but still fairly
widespread precipitation. With that in mind, have increases pops
to likely, and if trends continue can see it going higher. In
addition, could see some instability develop across southern
zones with progged CAPE values up to 500 j kg so have included a
slight chance for thunder there. Due to increased clouds and
precip, opted to knock down the previous forecast highs
significantly, only warming into the 60s to perhaps 70 across
the northern border. Showers dissipate from northwest to
southeast Tuesday night as the frontal boundary drops back
southward, with mild lows ranging from the mid 40s to mid 50s.

Long term Wednesday through Sunday
As of 329 pm edt Sunday... Overall, dry and warm conditions are
expected Wednesday afternoon through Friday night with
increasing chances for rain as we head through memorial day
weekend. A upper-level trough will linger over southern qc
through Thursday with a few spokes of energy rotating across the
area Wednesday afternoon-Thursday. Moisture will be limited
with NW flow through 500mb, therefore not anticipating much
rainfall however, have kept 20s-30s pops with greatest chance
for NE kingdom where moisture and lift may be better. Temps will
increase Friday as upper-level ridge and associated warmth move
east over new england. Clear, sunny skies with 925 temps around
20c should be supportive of near 80 degree temps. Clouds will
begin to increase Friday night ahead of our next system. Model
consensus at this time is more or less in good agreement about
a disturbance and tropical moisture streaming northward
beginning Saturday, but intensity and exact position of upstream
shortwave energy varies slightly... With that said however, 12z
guidance is indicating that Sunday may be trending more active
as approaching cold front and tropical moisture (pwats between
1.5-1.75" per gfs) coincide with MAX daytime heating (cape
values between 800-1500 j kg at this time) thus have included
mention of chance thunder in the grids.

Aviation 20z Sunday through Friday
Through 18z Monday... MVFR will continue to prevail through
about 21z this afternoon, mainly due to low ceilings, with
occasional improvement toVFR. Clouds will dissipate as we head
through the evening, with skies eventually clearing tonight.

West to northwest winds will remain around 10 kt this
afternoon, then become light overnight, then pick back up a bit
Monday morning once daytime mixing commences.


Monday night:VFR. No sig wx.

Tuesday: mainlyVFR, with areas MVFR possible. Chance shra.

Tuesday night: MVFR ifr conditions possible. Slight chance shra.

Wednesday:VFR. Slight chance shra.

Wednesday night:VFR. No sig wx.

Thursday night:VFR. No sig wx.

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.
