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.

Synopsis
High pressure will remain in control of the region through Friday
with dry weather and warm temperatures. Moisture will increase
across the eastern great lakes over the weekend and into memorial
day. This will bring a chance of a few widely scattered showers and
thunderstorms each day, but the majority of the time will be rain
free. Temperatures will be summer-like over the weekend and into
early next week, along with some increase in humidity.

Near term through tonight
Some patchy fog will continue early this morning, mainly across the
valleys of the western southern tier and the north country where
radiational cooling has been greatest. The extent of the fog will be
far less than early yesterday morning. The fog will quickly burn off
shortly after daybreak. Otherwise expect plenty of sunshine across
the region early this morning with quickly warming temperatures
after a cool start to the day.

High pressure will drift east across the eastern great lakes today,
with associated dry air and subsidence providing nearly full
sunshine. Expect highs to reach around 80 on the lake plains of
western ny away from lake influences, with 70s elsewhere. A general
southwest flow will be in place, keeping areas northeast of lakes
erie and ontario a little cooler, including buffalo and watertown.

The synoptic scale flow should be weak enough to also allow a lake
breeze to develop along the south shore of lake ontario, with
locally cooler temperatures there as well.

High pressure will drift to the mid-atlantic states tonight. Skies
will stay mainly clear overnight with subsidence and dry air still
in place. A weak wave will approach southern ontario late tonight,
but most of the associated cloud cover will stay north of lake
ontario. Expect enough breeze overnight to prevent any fog
formation. Lows will be in the upper 50s on the lake plains of
western ny, with low to mid 50s across the cooler southern tier
valleys and east of lake ontario.

Short term Friday through Sunday night
As we move toward the weekend, near perfect weather will be in place
across the region as high pressure moves over and east of the area
while weakening. Friday will feature warm temperatures in the low to
mid 80s, with plentiful sunshine and comfortable dew points in the
50s. As we move into Saturday, temperatures will remain relatively
stable, but moisture will increase across the region in the
southerly return flow on the back side of the surface high. Dew
points rising into the 60s will make for slightly less comfortable
conditions by Saturday afternoon. A few isolated to widely scattered
showers or thunderstorms are possible accompanying this increase in
moisture across the region, however the best chance will be in the
vicinity of the st lawrence valley near a stalled frontal boundary.

However, most will see far more dry time than anything else through
the first half of the weekend.

On Sunday, a shortwave will move across the eastern great lakes,
providing large scale ascent across the modestly unstable airmass.

Timing of the wave, along with interactions with any lake breeze
boundaries, will largely dictate how the precipitation thunderstorm
threat will evolve Sunday. While precipitation is likely Sunday, its
still worth noting it will not be a washout with quite possibly
ample dry time before and after showers or thunderstorms pass a
location. Increased cloud cover and precipitation chances will help
moderate temperatures somewhat with most locations seeing high
temperatures in the upper 70s to low 80s, however it will remain
humid with dewpoints pushing the mid 60s. Overnight lows will remain
in the low to mid 60s through this time frame.

Long term Monday through Wednesday
A frontal boundary will sag southward across the region Monday and
Monday night, keeping some scattered shower or thunderstorm chances
in place across forecast area. Then an area of high pressure builds
into the region Tuesday. The center of the high pressure will be
just north of lake ontario by Tuesday night, and will slide
southeast towards the new england coast on Wednesday. Tuesday
through Wednesday will be dry as this area of high pressure provides
tranquil weather for the region. Pw values will slowly increase as
the area of high pressure shifts to the east allowing for the next
influx of moisture and eventually shower chances later in the week.

High temperatures will generally be in the upper 70s to the low 80s.

Low temperatures will range from the upper 50s to lower 60s Sunday
night through Wednesday night. Both high and low temperatures will
be around 10 degrees above normal compared to late may averages.

Aviation 10z Thursday through Monday
Surface high pressure will drift across the eastern great lakes
today before reaching the mid-atlantic states tonight. Some patchy
fog will continue through the early morning hours, mainly across the
southern tier valleys and the north country with local ifr. The fog
will quickly burn off shortly after 12z, leavingVFR to prevail for
the rest of the day with skc. Mainly clear skies will continue
tonight with subsidence and dry air remaining in place.

Outlook...

Friday...VFR.

Saturday... MainlyVFR. A chance of showers or an isolated
thunderstorm.

Sunday and Monday... MainlyVFR with scattered showers and
thunderstorms.

Marine
High pressure will drift across the eastern great lakes today before
reaching the mid atlantic states tonight. This will maintain
relatively light winds across lakes erie and ontario, with winds
less than 15 knots and waves 2 feet or less. Local lake breezes will
develop today with winds becoming onshore. Southwest winds will
increase a little on Friday around the western periphery of the
departing high, but winds and waves will still remain well below
small craft advisory criteria.

Ny... None.

Marine... None.

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.
