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 build towards the eastern great lakes region from
canada today. This feature will provide for a fine first day of
summer with seasonable temperatures and light winds. A storm system
will bring rain showers and some thunderstorms later Friday and
through the weekend.

Near term through tonight
A weak cold front this morning is dropping across the north
country, with what is now just a thinning band of clouds.

Behind this front, surface high pressure will build towards the
eastern great lakes from near james bay. This feature will provide
for plenty of sunshine, light winds, low humidity and seasonable
temperatures in the mid 70s to around 80f.

Tonight this surface high will track towards northern new england,
just to the north of our region. Clear skies will rule much of the
night and temperatures will drop to the cooler side, with lows
ranging from the mid to upper 40s to around 50f.

A storm system over the ohio valley will begin to send some high
clouds towards our region late tonight.

Short term Friday through Saturday night
A nearly stacked low pressure system across the ohio valley Friday
will gradually weaken as it moves across the lower great lakes
through Saturday night. Surface high pressure across the gulf of
maine will keep much of Friday dry with clear skies lasting the
longest east of lake ontario. Chances for showers will increase
across far western new york during the day as this low pressure
system moves closer.

On Friday night southerly 850mb winds will increase to around 35 kts
resulting in moisture advection and diffuse warm air advection in
the mid-levels. A diffluent flow aloft will also support lift,
followed by the passage of what's left of the upper level low late
Saturday. Although modest, these sources of large-scale lift support
likely categorical pops for Friday night and Saturday with most
areas bound to get at least some measurable precipitation. This
said, there will be breaks between the rain showers, so we are not
looking at a complete washout.

Instability will be limited, but perhaps just enough to support some
thunderstorms, especially on Saturday with the passage of the
trough. These should be fairly sparse in nature and rainfall amounts
should average a quarter to half inch outside of locally higher
amounts. 00z model consensus is slightly faster with the remnants of
this low which is expected to exit into new england Saturday night
with chances for showers diminishing from west to east.

Temperatures will average near to slightly above normal. Highs on
Friday will mainly be in the 70s, with Saturday perhaps a few
degrees cooler due to cloud cover and showers. Lows temperatures
will range from the upper 50s to mid 60s with some modest
downsloping across the lake plains on Friday night.

Long term Sunday through Wednesday
An upper level trough axis will sharpen and move across the region
on Sunday with a cold front dropping south across western and north-
central ny. Model consensus is in good agreement with showers likely
with these features on Sunday. Instability parameters are very low
so only included slight chance for thunder.

Lingering chances for showers are in place Sunday night as models
show the parent mid level trough axis moving into new england. Temps
Sunday should reach into the 70s during the afternoon with dewpoints
in the 60s ahead of the front still supporting lingering humidity.

Behind the front, dewpoints will slip back into more comfortable
levels in the 50s Sunday night where overnight temps should slip
back into the 50s with light northwest winds and some breaks in sky
cover.

Canadian high pressure then looks to build over nys Monday and
Tuesday in the wake of the storm system and mid level trough axis.

The high is then forecast to shift off the east coast through
Wednesday. This surface high will provide our region with dry
weather through mid week. Temps will be seasonable Monday then will
rise a little bit each day through mid-week. Highs in the 70s on
Monday should warm into the 80s by Wednesday as southerly 850mb
winds advect warmer air into the region.

Aviation 12z Thursday through Monday
For the 12z tafsVFR flight conditions are found, and these
conditions are expected to continue through the TAF period with
light winds as surface high pressure remains near the region. A
weak cold front will drop across the north country this
morning, with mid level clouds over the north country
diminishing through the next 6 hours.

A warm front will approach wny late tonight. Mid and high level
clouds will begin to thicken across the region after 06z.

Outlook...

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 drop across lake ontario this morning, with a
northeast wind following. This wind will increase through the day
some, with speeds just over 10 knots... That will produce 3 foot
waves along the southern and southwestern shoreline of lake ontario.

Otherwise surface high pressure building towards the eastern great
lakes later today will bring lighter winds and minimal waves on the
eastern great lakes. Some showers and thunderstorms are possible
through the weekend, though for wind speeds and waves, small craft
advisory conditions are not likely to be meet.

Buf watches warnings advisories
Ny... None.

Marine... None.
