Synopsis
A broad upper level low will meander across the region through much
of this week, bringing periodic opportunities for showers and
thunderstorms along with near to slightly below average temperatures.

Near term through Tuesday
Upper low centered just north of lake superior will broaden with the
addition of upper energy dropping through central canada and the
northern plains. This system will encompass the great lakes through
Tuesday as it slowly wobbles east across ontario.

Upper shortwave pivoting around the low center will swing a
secondary cold front into our region overnight. Associated height
falls will drive an increase in cloud cover from the west and bring
renewed chances for some scattered showers and thunderstorms
arriving into western ny between midnight and 2am the progressing
east to the genesee valley western finger lakes by daybreak Tuesday.

Overnight temperatures will be mild as a southerly low level flow
persists in advance of the front, which will result in overnight
lows mostly in the mid to upper 50s.

The front will continue to push slowly into central ny Tuesday.

Atmosphere will destabilize sufficiently to allow for more robust
convection, especially inland from the lake shadows and well as east
of the genesee valley, where instability will likely be maximized.

Latest SPC day 2 outlook has areas from the genesee valley eastward
in a marginal risk for severe hail and wind gusts with the
convection Tuesday afternoon, but remains highly conditional on how
much destabilization occurs. 850 mb temperatures in the 8-10 c range
will allow most afternoon readings to climb into the lower 70s.

Short term Tuesday night through Thursday night
Upper level troughing will remain in place across the region
throughout the period, as an expansive upper low remains locked in
place near james bay. With cool cyclonic flow persisting across the
region, temperatures will remain several degrees below average, with
highs generally in the mid to upper 60s through the period, and
cooler readings northeast of the lakes, including the buffalo and
watertown areas, thanks to a persistent brisk southwesterly flow off
of the lakes that will be enhanced by diurnal lake breeze
circulations. Lows during the period will ranges from the low to mid
50s Tuesday night, to the upper 40s to lower 50s Wednesday and
Thursday nights, as the axis of the trough moves over the forecast
area, and cooler air filters across the region.

Regarding precipitation, we will likely see diurnal showers, and
possibly a few thunderstorms winding down Tuesday evening, as a
shortwave crosses the area. Depending on the speed of the shortwave,
we will likely have another round of convection develop Thursday
afternoon, particularly inland from the lakes, away from the
southwesterly lake shadowing. This convection will wind down quickly
Wednesday night, as the wave moves past and NVA associated
subsidence takes hold across the region, with weak ridging and dry
conditions prevailing Thursday. Pops begin to creep upwards once
again Thursday night, as theta-e advection begins to increase across
the midwest and lower great lakes in advance of a mid-level wave
dropping across the western great lakes.

Long term Friday through Monday
There will continue to be a deep cyclonic flow across the eastern
great lakes region. There will be some showers and thunderstorms on
Friday, but the weekend is likely to be mostly dry with only a small
chance for showers until the next system arrives Monday.

On Friday, model consensus continues to push a cold front southeast
across the region. This will produce scattered to numerous showers
and thunderstorms, supporting high chance pops just ahead of the
boundary.

A stacked low will shift from eastern canada to the maritimes
Saturday, which will allow an expansive surface high to build across
central canada. For our region, the forecast question is how far
south will the cold front make it, with the 12z ECMWF stalling the
boundary across pennsylvania, which is a bit too close for comfort.

A consensus suggests the boundary will likely settle south of the
area with the ridge extending into western new york. A shower cannot
completely be ruled out given the close proximity of upper level
trough and the frontal boundary just to the south, but it appears
a mainly dry weekend.

On Monday, a closed upper level low or trough will move across the
great lakes region. The 12z ggem ECMWF both favor the slower closed
low solution which would bring a greater chance for showers Monday
than the slightly more progressive gfs. For now, consensus supports
chance pops Monday, with the cool and moist pattern likely to
continue well into next week.

Daytime high temperatures will be below normal. Friday will be the
warmest day, with highs in the mid 60s to around 70. After that,
highs should be mainly in the 60s which is about 5-7 degrees below
normal.

Aviation 21z Monday through Saturday
Tonight, expect mainly dryVFR conditions during the evening, before
a secondary cold front pushes into the region overnight and brings a
renewed opportunity for some additional scattered showers and
thunderstorms. While mainlyVFR flight conditions should continue to
predominate overnight, some brief localized reductions to MVFR
cannot be totally ruled out within any showers or storms. During the
day Tuesday the risk for showers and storms will mainly be east of
a line from kjhw-kroc where some strong to sever storms may form.

Outlook...

Tuesday night through Saturday... MainlyVFR... With localized MVFR
possible in scattered to numerous showers and thunderstorms at times.

Marine
A secondary cold front will cross the region later tonight and
Tuesday, with another round of scattered showers and storms marking
its passage. In the wake of this second boundary, southwest winds
will again freshen across the lower lakes region on Tuesday,
particularly over lake erie where winds and or waves could reach
lower-end advisory levels.

A broad upper level trough will linger across the region through the
middle and latter portions of the week, resulting in a continued
general southwesterly to westerly flow, with this potentially
pushing advisory levels on lake erie on Wednesday.

Buf watches warnings advisories
Ny... None.

Marine... None.

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.
