area forecast discussion
national weather service buffalo ny
1055 am edt Fri may 24 2019

Synopsis
Cool and generally quiet conditions will continue over the area
as high pressure advances eastward through tonight. Conditions
will then deteriorate late tonight through Saturday night due to
a pair of frontal systems which will push through the region.

High pressure will then ridge southward from canada and into the
great lakes providing mainly dry weather for Sunday and Monday.

Near term through Saturday
Cyclonic northwesterly flow continues to dominate the forecast
area late this morning with remnant upslope shower activity
still plaguing especially lewis county. As the afternoon ensues,
low convective temperatures will likely preclude much in the
wave of progressive clearing even with the system to our east
departing, however its departure may be enough to counteract low
convective temperatures in terms of additional cloud expansion.

Thus, the status quo was generally held in skies for the
afternoon with a fairly wide range in temperatures dependent
upon the amount of insolation through the day... With the western
portions of the area away from water decidedly warmer than the
eastern portions.

Going into the evening and overnight hours, the remnants of the
mcs over ia and wi this morning will make a futile attempt to
crest the ridge sprawling through the great lakes. Hi-res model
solutions really eviscerate this MCS as it attempts to do this,
while the larger scale models hang onto some semblance of narrow
lifting on the front side of the circulation associated with the
decaying remnant mesolow. Low end pops were still maintained
across wny and the western southern tier for this during the
evening hours before dry conditions resume.

The mid-level ridge axis passes east of the CWA on Saturday
morning, allowing for flow to rapidly become southerly and then
southwesterly across the area with a warm front advancing
through the cwa. This will bring much more humid conditions into
the CWA as evidenced by pwat values jumping progressively
through the day toward 1.75 inches. With the warm frontal
passage, the deepest moisture and corridor of favored ascent
with a leading short wave looks to be just to the north of the
area with weaker moisture and shear fields farther south. Thus,
the best chances of precipitation from the warm frontal passage
looks to be just to our north, however things look to get a bit
more interesting once we are entrenched in the warm sector by
the afternoon.

With the aforementioned soupy 1.75 inch pwat environment
sprawled across most of new york state by Saturday afternoon,
and MUCAPE values vaulting toward 1000-1200 j kg, especially
over the southern tier, with 0-6 km bulk shear values on the
order of 35 kts, convective development seems a fairly good bet.

Activity seems likely to kick off fairly early with additional
redevelopment as the mesoscale environment plays out in terms
outflow interactions. That said, hi-res guidance is going
absolutely loopy in the warm sector. However, given that the
best shear doesn't start to arrive until very late in the day or
into the evening, and the apex of warm air doesn't get to our
area until this juncture, it would seem the best potential for
anything severe would hold off until then. That said, SPC does
have the area west of i-390 in a slight risk, and it would seem
the time period closer to the evening on Saturday would be the
window for this. Further, it would seem heavy rain would be more
problematic, anyway. Deep moisture, weakened afternoon shear,
and the potential for successive rounds of convective activity
will yield potential for heavy rain accumulations. This could
lead to localized flooding.

Short term Saturday night through Sunday night
Sunday a weak frontal boundary will drop southward across the
region. We will still be on the humid side to start the day and
a few showers or thunderstorms remain possible through the
afternoon as we'll remain unstable. This precipitation will end
through Sunday early evening as moisture depletes as surface
high pressure over canada funnels drier air southward. Skies
will clear through the night with overnight temperatures
dropping back into the lower 50s.

Long term Monday through Thursday
Increased ridging will begin on Monday over the eastern third of the
country. This will provide rainfree conditions for Monday, with
comfortable levels of humidity as surface high pressure to the north
pushes drier air southward.

As the ridge strengthens over the southeast u.S., a similar scenario
to this weeks weather will take shape. The ridge over the southeast
u.S. Will cause waves of low pressure to trek northeast out of
western half of the country where a trough will be in place. Waves
of low pressure will increase the chance for showers and
thunderstorms from Tuesday through Thursday across western and north
central ny.

Ahead of these areas of low pressure warming temperatures on Tuesday
and Wednesday will bring highs across the area to the upper 70s to
mid 80s. A passing cold front late Wednesday early Thursday will
bring slightly below normal temperates to the area with highs in the
mid to upper 60s.

Aviation 15z Friday through Tuesday
A closed low will settle across maine this morning which will
increase moisture and result in cloud cover and lower cigs
through the morning hours. This will result in areas of MVFR
clouds, especially east of lake ontario but also south of lake
ontario where these clouds will be more patchy in nature.

Cloud bases will lift late this morning, and eventually scatter
out this afternoon and evening with widespreadVFR flight
conditions. A warm front will approach from the southwest late
tonight. This will result in an area of low to mid level clouds
and possibly a shower or thunderstorm west of rochester near
daybreak Saturday.

Outlook...

Saturday...VFR MVFR with showers likely and a chance of
thunderstorms. Some storms could produce gusty winds.

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

Monday...VFR.

Tuesday... MainlyVFR with a chance of showers and thunderstorms.

Marine
Winds have picked up behind a cold front, which will support
small craft advisory conditions this morning, particularly along
the southeastern shores of lake ontario.

Winds will then subside this afternoon as high pressure will
push east from the upper great lakes. Generally light winds and
negligible waves can then be anticipated tonight and Saturday.

Tides coastal flooding
A cold front has moved across the area with westerly winds
producing higher waves, especially across the eastern half of
lake ontario. This combined with very high lake levels will
result in flooding along the shorelines of wayne... Northern
cayuga... And oswego counties. Winds and waves will diminish by
this afternoon which will lower the flooding concerns.

Buf watches warnings advisories
Ny... None.

Marine... None.
