Synopsis
Weak upper level disturbances, combined with lake moisture, will
trigger some scattered sprinkles in the finger lakes and mohawk
valley tonight and Thursday. Otherwise, high pressure building
into the region will provide mainly dry but cool weather through
the weekend.

Near term through Thursday
730 pm update...

only change made to the forecast was to increase pops and the
mention of scattered light rain in the finger lakes and mohawk
valley this evening. Any very light precip will dissipate before
midnight. There is some concern for too much cloud cover for
fog, but kept mention of patchy valley fog in the forecast for
now. Otherwise, no significant changes made to the forecast.

230 pm update...

a broad trof will reside over the northeastern u.S. Through
Friday with cool low level flow blowing from the northwest.

Models indicate weak waves will rotate around the upper trof at
times this evening and tomorrow. This weak forcing and lake
differential instability may bring a few light showers, or
sprinkles to the finger lakes and upper mohawk valley.

850 mb thermal trof over the region will mean unseasonably cool
temperatures in the lower-mid 50s with the upper 60s and lower
70s for highs.

Short term Thursday night through Saturday
230 pm update...

surface high pressure continues to flex its muscles heading into
the weekend as the upper trof weakens slightly. Low level flow
remains from the NW across the warm waters of lake ontario, but
weakens. Still some weak PVA rotating around, but atmosphere
below 700 mb really dries out. At this time, the 12z ECMWF is
the only model left with any kind of QPF on Friday, so the
consensus blend will be to reduce pops and keep things quiet
with no mention of sprinkles showers across the northern areas
through Saturday.

Mainly clear skies and the chilly dry airmass will mean
overnight lows colder than normal. Many areas will reach the
mid-upper 40s both Thursday night and Friday night. Highs also
sub-seasonal... Although gradually warming from around 70 Friday
to the lower 70s Saturday.

Long term Saturday night through Wednesday
230 pm update...

a nice stretch of weather. Mainly dry with temperatures slightly
below average. A broad trough of colder air aloft while high
pressure sets up at the surface Saturday night to Tuesday.

Beyond this much uncertainty and model differences. Tropical
moisture may approach from the southwest well ahead of tropical
depression harvey. In addition a weak cold front is possible
Wednesday or Thursday. Harvey may get here after that.

Aviation 00z Thursday through Tuesday
Vfr conditions will persist tonight for all forecast sites
except kelm where valley fog is expected to develop late this
evening and overnight. Restrictions may drop to ifr between
08-12z. Fog expected to lift by 13z. There may be a brief
sprinkle at ksyr in the morning, but otherwise, conditions will
remainVFR tomorrow as well.

Light and variable winds tonight. West to northwest winds 5 to
10 gusting to 15 knots Thursday.

Outlook...

Thursday night through Tuesday... MainlyVFR except for valley
fog at kelm.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
