Synopsis
Clearing skies and dry weather expected tonight into Friday as weak
high pressure builds in from the northwest. A frontal boundary is
then forecast to set up in the vicinity of the lower great lakes
this weekend, potentially bringing wet and unsettled weather at
times. Temperatures will remain near average through the end of the
week and this weekend.

Near term through Friday
Clear skies will persist through the overnight hours as weak surface
ridging builds into the area. Clearing skies and light winds will
promote radiational cooling, and with surface dewpoints still in the
mid to upper 60s across many areas, patchy fog can be expected to
develop overnight - particularly across the usual trouble spots in
the river valleys of the southern tier and niagara county. Areas
where heavy rain fell earlier this afternoon will also be more prone
to fog formation overnight. The aforementioned dewpoints will limit
temperature falls, yielding another muggy night across the region,
with lows in the mid 60s, with lower 60s to be found in the
north country.

Look for plenty of sunshine to wrap up the work week on Friday, as
high pressure will continue to drift east across the lower great
lakes. A modestly cooler airmass advecting across the region will be
offset by greater insolation, and the net result will be
temperatures that will be close to what we saw today, with highs in
the upper 70s to lower 80s.

Short term Friday night through Sunday night
High pressure to our east will maintain quiet conditions Friday
night across our region. It will be a muggy Friday night, and this
warmth and humidity will only increase Saturday as a warm front from
the west begins to push towards our southern counties. A ribbon of
much higher theta-e along this warm front will likely produce
showers and thunderstorms later Saturday and Saturday night. This
activity will need to be watched for severe potential as 0-6 km bulk
shear values reach 40 to 45 knots, sb CAPE values increase to 1500
to 2000 j kg. Greatest threat for severe weather in our CWA will be
along lake erie and across the so. Tier. We will continue to mention
this possibility within the hwo produce for now.

Sunday and Sunday night we will remain humid, and as the main
surface low tracks across the region, additional showers and
thunderstorms will remain possible.

Temperatures will remain at or just above normal through the period,
especially Saturday night where a few locations may not drop below
70f across wny.

Long term Monday through Thursday
As we move into the longer term portion of the forecast... General
chances for showers and thunderstorms should linger through both
Sunday night and Monday as upper level troughing digs across our
region... And as the axis of the surface low settles southeastward
to the mid-atlantic coastline. Any leftover showers should then come
to an end between Monday night and early Tuesday as high pressure
and cooler drier air begins building into our area... With fair and
dry weather then following for the rest of the period as the high
first settles directly overhead... Then slowly drifts eastward to
the atlantic coastline.

Regarding temperatures... The digging upper trough and arrival of
cooler and drier air will translate into temperatures and humidity
levels falling off through Tuesday... Which should feature daytime
highs generally be in the mid 70s and comfortable dewpoints in the
mid to upper 50s. Both will then begin to rebound some on Wednesday
as the axis of the ridge slides to our east and a southwesterly
return flow develops on its backside... Resulting in temps climbing
back to around 80 degrees and dewpoints recovering to around 60
or so.

Aviation 03z Friday through Tuesday
Fair skies are in place across the forecast area this evening and
are expected to remain in place through the overnight hours, as high
pressure builds into the lower great lakes. However, the
combination of light winds, clear skies, and high dewpoints in
the mid to upper 60s will promote valley fog formation in the
southern tier that may end up bringing ifr and potentially lifr
conditions to kjhw after 06z. Patchy fog may end up being an
issue at kart kiag kroc as well. For Friday, expect widespread
vfr conditions to persist throughout the day, as high pressure
continues to slide east across the forecast area.

Outlook...

Friday night...VFR.

Saturday and Sunday...VFR MVFR with some showers and thunderstorms.

Monday... MainlyVFR but with a chance of showers.

Tuesday...VFR.

Marine
High pressure over the upper great lakes tonight will expand across
the lower great lakes for Friday and Friday night. This will result
in fine conditons for recreational boating to end the work week. A
frontal boundary is then expected to stall near the lower great
lakes this weekend with chances of showers and storms again becoming
a threat but winds waves are expected to remain on the light side.

Ny... 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.
