Synopsis
There may be a few lingering showers overnight, with otherwise
mainly dry and unseasonably cool temperatures. The upper level
disturbances responsible for the cool and unsettled weather will
move east Wednesday with high pressure bringing mainly dry
weather. Another storm system will track into the great lakes on
Thursday with a warm front bringing more showers and
thunderstorms along with a return to uncomfortable humidity
levels.

Near term through Wednesday
An upper level trough axis will move into new england
overnight. Regional radar shows widely scattered showers across
western new york which should continue to taper off overnight.

The combination of cool air aloft and warm lake temperatures
will result in some modest lake enhancement, mainly east of lake
ontario along a land breeze convergence boundary. Temperatures
tonight will fall into the upper 40s to low 50s.

On Wednesday, surface high pressure over the ohio valley will nose
into the region, building in a warmer and drier airmass. A few
diurnal, scattered showers will be limited closer to the upper-level
low over the north country. Otherwise, diurnal cumulus clouds will
form over western ny. 850 mb temperatures will start to recover into
the low teens, bringing daytime highs back into the low 70s.

Short term Wednesday night through Friday night
Wednesday night high pressure slides off the carolina coast with a
southerly flow developing across our region. Rain from next
approaching system will reach parts of western and northern new york
late Wednesday night. Rain continues to overspread the region on
Thursday as a warm front lifts northward across the region. Enough
instability will develop such that embedded thunderstorms Thursday
will continue into Thursday night.

The weakening surface low will leave a weak frontal boundary across
the region on Friday with a few more showers and thunderstorms on
tap.

Temperature-wise, finally back to normal readings for the end of
june beginning of july. Highs Friday reaching the upper 70s to near
80 and on Friday into the low 80s. Low Wednesday night in the mid
50s to around 60. As the air becomes more humid, Thursday night and
Friday night temperatures will remain in the mid to upper 60s.

Long term Saturday through Tuesday
Saturday will start of warm and humid with a warm frontal boundary
moving north or already north wny. This will leave the region in
the warm sector of a low moving NE across huron during the day. A
cold front associated with this low will move in sometime on
Saturday and spark additional thunderstorms. Frontal timing will
determine the threat for stronger storms, with a better chance
inland toward cny if current model trends hold.

Saturday night and Sunday... This time period should mark the end of
an active pattern with high pressure slowly moving in with drying in
at least the mid levels. The main threat for additional showers
will be on Sunday afternoon along lake breeze convergent regions.

Sunday night and Monday... This period should be dry with weak high
pressure moving toward the region from the upper midwest. Dry
weather area-wide isn't a guarantee this far out, but if the timing
of the current pattern holds, the natural progression should be
subsidence behind the Sunday system, with the exception of isolated
summer convection on lake breeze convergent regions by Monday
afternoon.

Monday night and Tuesday... High pressure generally over head should
negate any threat for convection. The 12z GFS is more optimistic
precipitation from the WV va appalachians into pa while the ec is
dry with a slightly stronger ridge over ontario extending S into ny.

Will lean on the dry side for now as the GFS has had some model
variability further upstream over the midwest when compared to a
more consistent pattern noted in successive ec runs.

Daily temperatures won't stray too far off normals for this time of
year, with highs in the mid 70s to near 80 and lows mostly in the
60s, with a slight cooling trend into early next week. Humidity
levels will vary, with some nights possibly warranting a c while in
the warm sector, but at this time don't see any extreme sultry days
or nights for weekend early next week. The warmest and most humid
period will be early during Saturday while in the warm sector.

Aviation 02z Wednesday through Sunday
ExpectVFR conditions tonight and Wednesday. Widely scattered
showers late this evening will continue to taper off, with
only a small chance of even briefly impacting any given taf
location. High pressure will build into the region on
Wednesday, with scattered to broken diurnal CU likely to stay
above 3k ft. A few showers cannot be ruled out across the north
country, but these are likely to miss the art terminal.

Outlook...

Wednesday night... MainlyVFR.

Thursday through Sunday...VFR MVFR with a chance of showers and
thunderstorms.

Marine
Winds have diminished late this evening, but waves are still to
5 ft on lake erie and 4 ft on lake ontario. Small craft
headlines are in place for lake erie until midnight.

Lighter winds will promote sub-advisory wave action on the lakes
from tonight and Wednesday. Winds and waves will again increase
Thursday ahead of the next frontal system pushing toward the eastern
great lakes.

Buf watches warnings advisories
Ny... None.

Marine... Small craft advisory until midnight edt tonight for lez040-041.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
