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.

Synopsis
Expect some sprinkles south of lake ontario through mid afternoon
with some rain showers across the southern tier as a weak wave of
low pressure tracks to our south. A weak cold front will cross the
region tonight with high pressure building through the end of the
work week, brining dry and comfortable conditions. A storm system
will approach for the weekend bringing rain showers and some rumbles
of thunder, mainly Saturday, with a few showers lingering into
Sunday.

Near term through Thursday
A weak shortwave and attendant surface low tracking through the
northern ohio valley and into pa today will bring a wealth of mid
and high level cloud cover across the region. A layer of very dry
air near the surface per the 12z buf sounding will preclude much
precipitation today, keeping us mainly dry. However, a period of
moderate rain aloft through early afternoon will allow for some
scattered sprinkles south of lake ontario and showers across the
southern tier to actually make it to the surface. Measurable
precipitation of less than an tenth of an inch will be limited to
the southern tier. Any showers or sprinkles will quickly taper off
from west to east by mid to late afternoon, leaving us a completely
dry evening. An important note, the radar will likely appear much
more ominous than precipitation will actually be today, since it
will be seeing the rain aloft, however much of this will evaporate
before actually reaching the surface. Otherwise, light winds, cloud
cover, and temperatures only in the low to mid 70s will actually
make for a fantastic and comfortable day for outdoor activities.

A surface high will push toward southern ontario canada tonight.

Meanwhile a shortwave rounding a longwave trough over eastern canada
will drive a backdoor cold front across quebec, northern new york
and new england tonight. Shower activity along this front will
remain near the upper level support well outside the forecast area,
though a stray shower or two may clip eastern jefferson northern
lewis counties. Lows tonight will drop back into the 50s with a
light wind.

High pressure will continue to build across the region Thursday with
mainly clear skies and light northerly winds advecting in a cool and
dry canadian airmass. The result will be a phenomenal june day with
highs in the low to mid 70s and very low humidity.

Short term Thursday night through Saturday night
A nearly stacked low pressure system will move into the ohio valley
while high pressure slowly moves off the gulf of maine Thursday
night. Mostly clear conditions will continue Thursday night as
moisture stays confined southwest of the forecast area. Moisture
will begin to enter the region Friday and into the weekend as high
pressure moves off the northeast coast and low pressure progresses
eastward.

Low pressure will advance eastward Friday while a warm front
approaches the forecast area. Winds aloft will veer from the
southeast to south causing moisture to advect into the forecast
area. Overrunning will cause clouds to increase from south to north
Friday and light-intermittent rain will likely spread across western
ny through the afternoon. Since a dry airmass will still have its
hold on the region Friday, rain will be light and may only account
to trace amounts.

Warm air advection ramps up Friday night as 850mb winds increase to
30kts and the warm front moves into western ny. Rain will increase
in coverage as the stacked low pressure system moves near western
lake erie by Saturday morning. As the warm front moves northward and
into the north country Saturday, 65-70 deg dewpoints will spread
northward while a shortwave trough rounds the base of the low
pressure system. This will lead to more widespread showers and the
chance for thunderstorms. At this time, the area from the southern
tier to the southern shore of lake ontario has the best chance for
thunderstorms through Saturday afternoon. As the shortwave trough
moves eastward into Saturday night, the chance for thunderstorms
will expand into the north country.

Temperatures will be near normal Thursday night-Friday and become
above normal through the weekend.

Long term Sunday through Wednesday
An exiting low pressure system will drag the first of two cold
fronts thorugh our region on Sunday. While the majority of the day
will be rain free... There will be the potential for some showers and
even a thunderstorm. A secondary cold front is then expected to
make its way through our area Sunday night... But with a lack of
instability and less forcing... Will only carry a minimal chance for
a few more showers.

Medium range guidance is now suggesting the passage of a fairly
strong shortwave late Sunday night or early Monday. Will increase
the sky cover from continuity... And also add slgt chc pops for the
north country... To cover this potential. Otherwise... Monday should
feature pronounced improvement over the weather from the weekend as
we will return to at least partial sunshine with much more
comfortable conditions.

The next area of canadian based high pressure will make its way
across the lower great lakes Monday night before settling to our
southeast on Tuesday. This will promote beautiful weather across our
region with mainly clear skies and pleasant temperatures and
humidity levels.

Aviation 19z Wednesday through Monday
WidespreadVFR conditions will prevail today. Scattered showers and
sprinkles are expected south of lake ontario, however these will
fall from a 5-10kft deck with vsbys 6 sm or greater. Any showers
will end later this afternoon and evening, with otherwise dry
conditions and light winds prevailing.

High pressure will maintain fair weather andVFR conditions through
Thursday.

Outlook...

Thursday night through Friday...VFR.

Saturday...VFR MVFR... Showers and thunderstorms likely.

Sunday... MainlyVFR. A chance of showers and thunderstorms.

Monday...VFR.

Marine
A weak cold front will cross the lower great lakes tonight with
northeasterly winds increasing behind the front, however conditions
will remain below sca. High pressure will build across the lakes for
the end of the work week with optimal boating conditions. A low
pressure system will pass near the lakes over the weekend brining
more unsettled weather, however winds and waves are expected to
remain below SCA at this time.

Buf watches warnings advisories
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.
