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 across the region will continue dry weather and
comfortable temperatures through tonight. A weak wave and area of
low pressure will track south of the region Wednesday, with a few
scattered showers and more cloud cover south of lake ontario. A weak
cold front will cross the region Wednesday night, with canadian
sourced surface high then expected to build into the lower lakes
with dry and fair weather through the end of the week.

Near term through Wednesday
Satellite imagery showing mid high clouds covering most of the
region late this evening with the exception of the north country,
with plenty of clouds upstream from southern ontario into michigan.

Given the recent satellite trends, most areas will remain mostly
cloudy overnight. The one exception will be the north country, where
high clouds will stay thin enough to remain partly cloudy. Radar
imagery shows a few light returns upstream across southern ontario,
but surface obs show little of this reaching the ground with
extensive sub-cloud evaporation. Any showers that do develop should
hold off until after daybreak. Expect lows in the mid to upper 50s
in most areas, with upper 40s to lower 50s for the north country
where clouds remain thinner.

On Wednesday a weak shortwave tracking out of the northern plains
will push a weak surface low south of the forecast area. Upstream
convection attendant to this feature continues to give the forecast
models some difficulty in resolving the track of the wave. Nam-based
guidance has trended a bit northward over the previous model runs,
while the medium range global models remain farther south. Have
hedged the forecast pops back to the north slightly out of respect
to the NAM based guidance. However, either way, QPF amounts should
be on the light side as the moisture will be eroded as it runs into
the drier air associated with the surface high to our east. Thus,
continue to keep pops limited to the chance range, even across the
southern tier, as there will likely be far more dry time than not on
Wednesday. Temperatures will range from the low 70s across the
southern tier where thicker cloud cover is expected to near the 80
degree mark across the lake plains.

Short term Wednesday night through Saturday
Wednesday night broad low pressure over labrador will push a dying
weak cool front southeastward across our region. With this feature
starved for both moisture and upper level support it should come
through largely dry... Save for perhaps the saint lawrence valley
and portions of the north country where a few isolated to widely
scattered light showers cannot be completely ruled out. Otherwise
the front will merely be marked by a brief limited increase in
cloud cover and a wind shift... With overnight lows ranging from the
lower 50s across the north country and interior southern tier to
the mid 50s elsewhere.

Following the passage of this boundary... Expansive canadian high
pressure will build southeastward across our region through Thursday
and Thursday night. Copious amounts of dry air and large-scale
subsidence attendant to this burgeoning ridge will provide our
region with pleasant weather... With mostly sunny mainly clear skies
accompanied by comfortable temperatures and humidity levels. Daytime
highs on Thursday should be in the lower to mid 70s... With the above
mentioned mainly clear skies... Light winds... And dry airmass then
allowing Thursday night's lows to dip into the lower to mid 50s
across the lake plains... And into the mid to upper 40s across the
north country and interior portions of the southern tier.

On Friday the surface ridge will slowly drift eastward and off the
new england coastline... While a closed mid level low over the mid-
mississippi valley gradually opens up and pushes into the lower
ohio valley... While preceded a bit by its attendant surface low.

The developing warm air advection regime between these two systems
will result in a gradual southwest to northeast increase in cloud
cover across areas south of lake ontario... With the warm frontal
zone attendant to the encroaching low now appearing to get close
enough to warrant the chance of a few late day showers across extreme
far southwestern new york. Otherwise the day should be dry with
fairly plentiful sunshine still prevailing across the eastern
finger lakes and north country... With the overall warm advection
pattern also helping daytime highs to climb back into the upper 70s
and lower 80s. This stated... Surface dewpoints will remain confined
to the lower to mid 50s... So it should still be rather comfortable.

Friday night and Saturday the now-open mid level trough will eject
northeastward across the ohio valley and great lakes... While its
associated broad surface low will meander its way northeastward into
nearby southern ontario and push its surface warm front into our
region. Increasing warm advection isentropic lift and moisture
pooling out ahead of the warm front will result in shower chances
ramping up from west to east Friday night... Followed by a numerous
showers and possible scattered thunderstorms areawide on Saturday
as some instability also gets added to the mix. With this in mind
have continued to trend pops upward for this 24 hour period... With
high likely pops reaching far western new york later Friday night...

then overspreading the entire area during Saturday. Meanwhile steady
warming and moistening of our airmass should translate into lows
mainly in the lower half of the 60s Friday night... With highs in
the 75 to 80 range on Saturday accompanied by the return of more
humid conditions as dewpoints surge back into the lower 60s.

Long term Saturday night through Tuesday
As the warm front pushes north of our region Saturday night... We can
look for a general decrease in coverage of the shower activity. The
extent of the showers should pick up again on Sunday when the
exiting storm system will drop a cold front through the region.

There will also be a renewed risk for some thunderstorms... Although
the bulk of the day should be rain free.

A large canadian high will then build south across the great lakes
Sunday night and Monday. This will promote clearing skies later
Sunday night with the return to beautiful weather Monday when we can
look forward to comfortable temperatures and much lower humidity.

Aviation 02z Wednesday through Sunday
Vfr will prevail for the 00z tafs. Extensive mid high clouds will
continue overnight. The mid level clouds will persist through much
of Wednesday, especially along and south of the south shore of lake
ontario. A few light showers may develop across western ny, but the
low levels will remain unsaturated so expect CIGS vsby to remainVFR
even if showers materialize.

Outlook...

Wednesday night through Friday...VFR.

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

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

Marine
High pressure across the region will maintain tranquil conditions
on the lakes into Wednesday. A weak cold front will cross the lakes
Wednesday night, but northeast winds and waves will remain below sca
conditions. High pressure will build across the region again through
the end of the week keeping an extended period of optimal boating
conditions.
