Area Forecast Discussion
National Weather Service Buffalo NY
1254 PM EST Fri Nov 23 2018

.SYNOPSIS...
High pressure will drift off the New England coast today and keep
our region dry. Warmer temperatures will arrive this weekend as
southerly winds develop. A trough will bring precipitation back
into the region Saturday and Saturday night. If the precipitation
moves in quickly enough, a brief period of freezing rain is
possible at the start, otherwise rain is expected with this
system. Mainly dry weather returns Sunday. Warm temperatures
last through Monday before turning colder again by the middle of
next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
A return south to southeast flow around departing Arctic high
pressure to the southeast will bring a significant improvement
in temperatures today. The combination partial sunshine along
with warm air advection will lead to temperatures into the lower
to mid 30s across western New York, but remaining in the 20s
across interior sections of the western Southern Tier and
central New York.

A well defined area of clouds along a weak warm frontal
boundary will move across the region today. At noon this was
between Buffalo and Watertown, with bright sunny skies outside
of this cloud shield. Expect Rochester to clear out around mid-
afternoon, and Watertown around sunset.

The mild southerly flow will persist into tonight as the next
shortwave and associated low pressure/surface trough pivots
through the Great Lakes. Overnight low temperatures in the mid
20s to lower 30s across most of the area with upper teens to
lower 20s across interiors sections will be reached earlier in
the night, then slowly rise toward Saturday morning.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/...
This will generally be an unsettled period...as a pair of systems
will push through the Lower Great Lakes. The good news is that the
majority of the upcoming precipitation will be in the form of rain.
This will not be the case for later Monday night through much of the
upcoming week though...when a renewed cold airmass will come with
the promise for accumulating snows. More on that in the very wintry
Long Term discussion below.

When we open this period on Saturday...negatively tilted mid level
support will push a Pacific based frontal boundary across the
forecast area. While there will be a fairly decent slug of moisture
associated with the system...the forcing will mainly come from a 50-
60kt low level jet that will impinge upon the aforementioned sfc
boundary. This will virtually guarantee that everyone in the
forecast area will experience a little rain...but the day will not
be a wash out. In fact...the deep southerly flow that will be in
place will limit the amount of rain experienced along the lake
plains from Buffalo to Syracuse with amounts generally under a
quarter inch. The same flow will result in some upslope enhancement
though for parts of the Southern Tier and for the Eastern Lake
Ontario region where a third of an inch of rain will be possible.
The rain could begin as a little wet snow or freezing rain across
the Southern Tier before 10 AM...especially considering the recent
cold which will certainly have elevated surfaces primed. Otherwise
it will become a milder day with temperatures in most areas climbing
into the 40s...right where we should be for late November.

The frontal boundary and associated band of moisture will exit to
the east of the forecast area Saturday night...while low level
ridging will start to build across the western counties in its wake.
This will allow the light rain to taper off and end as some nuisance
shower activity. For those traveling...temperatures will remain
elevated enough (both in cloud and at the surface) to preclude any
problems from any wintry precipitation.

On Sunday...a supportive mid level ridge will make its way across
the Lower Great Lakes. While we can anticipate fair dry weather...
this will be a 'dirty' ridge with enough lift from the on going warm
advection to keep at least alto-cu cigs in place. This will
especially be the case for areas from the Lake Ontario lake plain
north and east into Canada. The good news from this scenario is that
relatively mild weather will be experienced with temperatures
climbing into the mid and upper 40s.

It will become quite interesting Sunday night...as a well
organized...995mb low will track from Illinois to western Lake Erie.
A divergent upper level flow and associated jet dynamics to the
north of this storm system will produce a shield of moderately heavy
rain that should stay just to our west. However...the leading edge
of this pcpn shield should make it to at least the far western
counties during the overnight hours. Guidance is having a little
trouble with it...as one line of thinking as that the storm system
will stay intact and continue to deepen as it passes to our west to
southern Ontario. The other scenario is that the storm system will
follow the progression of a Miller B cyclogenetic event...with the
primary storm weakening and slowing as it approaches Lake Erie while
a secondary starts to take shape along the Mid Atlantic coast. Given
pattern recognition and climatology...the latter series of events
seems more plausible. While it will still get rather windy across
the region as a coastal storm develops and subsequently deepens on
its way up the New England coast...the risk for problematic winds
should be minimized. If the transition to a coastal low is delayed
by 24 hours though (ie. operational GFS solution)...then strong
winds will have to be considered. Will lean away from this for now.

On Monday...energy from the primary storm system will continue to
feed into the developing coastal storm while an open trough will
slowly push northeast across our forecast area. This will support
fairly widespread pcpn over our region...most likely in the form of
rain. Will maintain cat pops inherited from continuity.

Notably colder air will charge back across our region in the wake of
the transitioning storm system Monday night. This will allow
leftover synoptic based rain showers to change to snow showers...
with -10c air supporting lake effect snow southeast of Lake Erie.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
There is high confidence that temperatures will average below
normal...possibly by as much as 10 degrees...during this period.
This forecast is supported by strong consensus among the medium
range ensembles that a large closed low centered over the Upper
Great Lakes at the start of the period will take several days to
'open up' and rotate out across the Canadian maritimes to the
open waters of the North Atlantic.

H85 temperatures over the Lower Great lakes during this period will
average between -8 and -10c...which will certainly be low enough to
support lake snows downwind of both Lakes Erie and Ontario. While
there is some spread in the variance of the steering winds between
the ECMWF and GEFS ensembles...there is the risk for a prolonged
westerly fetch lake snow event. This would target the Tug Hill and
portions of the Southern Tier with several feet of snow...so stay
tuned for refinements in the forecast and possible watches.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
VFR conditions expected through tonight. A deck of clouds in the
4-6 kft agl range will pass across New York state through early
to mid afternoon. These clouds will scattered out from the
southwest by early tonight.

Winds will increase aloft with a period of LLWS late tonight and
into Saturday morning. There also will be an area of rain which
will move into the area from west to est during the day. This
may start off briefly as freezing rain at KJHW. Flight
conditions will mainly be VFR or MVFR at KBUF/IAG/ROC/ART due to
downsloping which will help dry out the boundary layer. Expect
KJHW to lower to IFR shortly after the arrival of precipitation.

Outlook...

Saturday night...MVFR/IFR in rain showers.
Sunday...MVFR/IFR in lingering low stratus.
Monday...MVFR with rain showers likely.
Tuesday...MVFR/IFR with rain showers mixing with and changing
to snow.
Wednesday...Variable VFR to IFR with lake effect snow, probably
located to the east of the lakes.

&&

.MARINE...
High pressure will move to New England this afternoon, with
southerly winds increasing. Greater wave action will be confined
mainly to Canadian waters given the SSE wind direction.
Southerly winds will increase to 15 to 25 knots late this
afternoon and remain in this range through early Saturday
afternoon. As a result, Small Craft headlines were issued for
the winds more so than the waves.

Winds will fall back Saturday night and Sunday, before a deepening
surface low tracks across the lower Great Lakes on Monday. Some
model differences exist regarding exact timing and track of the low,
but high end small craft conditions look likely with low end gales
possible.

NY...None.
MARINE...Small Craft Advisory until 1 PM EST Saturday for LOZ045.
