Area Forecast Discussion
National Weather Service Buffalo NY
119 PM EST Wed Jan 18 2017

.SYNOPSIS...
Low pressure with track up the Saint Lawrence Valley this morning,
while low cloud cover and areas of drizzle and scattered rain
showers linger across western and North Central NY today. It will
then remain mild through the rest of the week, with even warmer air
for the weekend. The next chance of widespread rain comes Monday
into Monday night as a large low pressure system approaches.

&&

.NEAR TERM /THROUGH TONIGHT/...
Areas of light rain showers and drizzle will continue to move
through western and North Central NY near the surface low and
trailing boundary late this morning. WV and IR satellite imagery
also indicate drier air in the mid and upper levels to our northwest
that will move into the region this afternoon. It will remain
overcast today with low cloud cover. This cloud cover, combined with
the weak cold advection in the wake of the departing low and frontal
passage will result in near steady temperatures today that will
likely rise little, if any, from their morning readings by this
afternoon. This means temperatures stuck in the mid to upper 30s for
most locations today.

Continued trapped low level moisture will keep the low overcast in
place tonight with light southwesterly winds in place. The result
will be little temperature change overnight, with lows tonight only
in the low to mid 30s.

&&

.SHORT TERM /THURSDAY THROUGH SATURDAY NIGHT/...
Increasing amplitude within the southern stream upper height field
will yield a period of rather benign weather Thursday and Thursday
night. Increasing subsidence and dry air advection will allow for
some sunny breaks Thursday especially during the afternoon.
Otherwise, looking at a continuation of above normal warmth, as even
neutral or weak warm air temperature advection of the resident air
mass yields afternoon readings of upper 30s to lower 40s.

An upper level low lifting northward through the Central Plains on
Friday will bring a chance for rain to western New York as a upper
level wave and weak surface low lift northward through the Great
Lakes. Some uncertainty remains among latest model solutions
regarding rain probabilities. European favors a higher chance of
rain with a stronger wave and surface low lifting northward. GFS/CMC
favor lower chances with a weaker low. A developing southerly flow
over the eastern Great Lakes will bringing unseasonably mild
temperatures with highs in the 40s to near 50 both Friday and
Saturday.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
A progressive...yet highly amplified upper level pattern will be
found across the country during this period...with the Great Lakes
region being dominated by mild Pacific modified air. While this will
mean that temperatures will remain well above normal...the period
will be highlighted by what could be a soaking to problematic rain
on Monday into early Tuesday. More on this in a moment.

A ridge axis over eastern New York will support one more fairly nice
day across our forecast area on Sunday...although clouds will likely
prevail across the western counties. Temperatures will be some 15
deg F above normal values...with highs ranging from the upper 40s
across the far western counties to the lower 40s on the Tug Hill
plateau.

The fair weather will deteriorate Sunday night as a deep stacked low
over the Deep South will start to work its way up the western slopes
of the Appalachians. Ahead of this very dynamic system...a plume of
sub tropical moisture will stream northward from the Caribbean and
Gulf stream of the western Atlantic to Virginia and Pennsylvania. As
the leading edge of this moisture will make its way across our
western counties late Sunday night...it will be lifted by a strongly
divergent upper level flow. This will start the process whereby our
region could pick up a soaking rain.

On Monday...the vertically stacked storm system will slowly drift
north across the Upper Ohio Valley while the plume of sub tropical
moisture off the Atlantic will edge over our region. This will lead
to some widespread rain for our forecast area Monday and Monday
night. The highest risk for significant rains will be east of the
Finger Lakes.

Guidance continues to suggest that this storm system will also
support strong...potentially damaging...downslope winds between Lake
Erie and the Chautauqua Ridge. A southeast low level jet of 50-55
knots just above a staunch inversion is very similar to events that
local research has shown to be problematic. Stay tuned.

The slow moving storm system is forecast to cross Pennsylvania on
Tuesday while its plume of moisture will push across far eastern New
York into New England. Meanwhile..drier air in the mid levels will
advect across the western counties on Tuesday with dynamics
weakening considerably in the process. This will lead to a tapering
off of the rain from east to east.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Widespread IFR to LIFR conditions will prevail tonight as trapped
low level moisture will maintain a low stratus deck. Light rain
showers and drizzle will taper off this afternoon, with just low
stratus clouds remaining. Low ceilings will lift a bit to MVFR for
most locations on Thursday morning but moisture off Lake Ontario may
keep KROC at IFR ceilings through the day. Expect clearing from
south to north later in the day.

Outlook...

Thursday...MVFR and areas IFR early...then becoming VFR late.
Friday...Mainly VFR. Friday night and Saturday...MVFR to IFR with a
chance of rain.
Sunday...MVFR ceilings.
Monday...MVFR to IFR ceilings with scattered showers. Windy.

&&

.MARINE...
Small craft conditions will continue on Lake Erie through midday in
the wake of a surface low currently departing across eastern Lake
Ontario. Winds will taper off on Lake Erie this afternoon and
evening. However, winds will pick up on Lake Ontario by this
afternoon and evening behind the surface low, and will result in a
period of small craft conditions for the south central shoreline.

&&

.BUF WATCHES/WARNINGS/ADVISORIES...
NY...None.
MARINE...Small Craft Advisory until 1 AM EST Thursday for LOZ043-044.
