Area Forecast Discussion
National Weather Service Binghamton NY
328 PM EST Thu Mar 9 2017
.SYNOPSIS...
A low pressure system, passing by to our south, will bring
parts of the area snow tonight into Friday. This will mainly
impact northeast Pennsylvania and Sullivan County New York. This
system will be followed by an arctic front bringing very cold
conditions for this weekend.
&&
.NEAR TERM /THROUGH FRIDAY/...
Gusty W/NW winds continue this afternoon in pressure gradient
behind low over Atlantic Canada. A frontal boundary is situated
just off to the south over central PA. In the very near term,
still have some concerns for the next couple hours from Twin
Tiers southward for increased brush fire risk due to winds and
low RH values. Winds will finally relax early this evening
bringing this threat to an end. Beyond this time, attention will
be on low pressure system which is still slated to develop
along baroclinic zone and move by south of the region off the
mid Atlantic coast tomorrow. The latest model guidance is just
a bit farther south with this low and also a little later with
the onset of precipitation which makes sense given how dry
profiles are. For this reason, delayed onset of Advisory until
3z but it remains in effect for same zones over NE PA. Expect
onset of precip to be in the very late evening into the early
overnight. A little rain or mixed precip may occur at the start
before a change to all snow occurs. Steadiest and heaviest
precipitation will occur late tonight into the first part of
Friday morning before snow winds down west to east. With the low
passing south of the region, heaviest precip will again be over
our southern zones of NE PA where 2-5 inches expected. There
will likely be a fairly tight gradient along the northern edge
of the system and at this point, thinking is for just a coating
up to an inch so over the Twin Tiers with no snow accumulation
for points north.
Above system will move out west to east late Friday morning into
the early afternoon but will be quickly followed by another
front moving through bringing a reinforcing shot of cold air.The
remainder of the day will feature strong gusty, winds with
scattered snow flurries and snow showers in W/NW flow. Due to
deep mixed layer, cold advection pattern and strong
environmental flow we have increased the winds in the grids for
tomorrow as we generally expect winds gusting 25 to 35 mph by
afternoon. Lows tonight will generally be in the 20s to low 30s
and won't rise too much Friday due to cold advection.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
145 pm update... A cold, wintry period is in store.
Friday night through Saturday, as an upper-level low slowly
swings across Quebec and towards the Maritime Provinces, a deep
NW flow of cold air will prevail across CNY/NEPA. Given a
300-310 wind trajectory, the pattern is generally favorable for
LES over much of CNY. However, amounts continue to look fairly
light, with dry near-surface air and lowering inversion heights
(dropping from 750-800 mb Friday night, down to around 850 mb
Saturday) the main detractors. Also, we're getting to the time
of year when lake-effect snow showers during the afternoon tend
to exhibit cellular/disorganized characteristics. Bottom line,
in the most favored areas (elevated terrain of southern Onondaga
and southwestern Madison counties), accumulations should be on
the order of 1-2" about every 12 hours. Outside of the main
lake-effect areas, occasional flurries and partly cloudy skies
are foreseen.
Again, the main story perhaps, will be the bitter cold wind
chills. Progged apparent temperatures will easily drop into the
-10 to -20F range later Friday night and Saturday morning, from
the southern Tug Hill and Mohawk Valley regions, southward
through the Catskills. Wind Chill Advisories may ultimately be
needed for these areas, and we'll continue to highlight this in
the Hazardous Weather Outlook. Elsewhere, with slightly less
wind, we're looking at zero to -10F apparent temperatures much
of the time (still no bargain). Actual air temperatures will
only manage to reach the teens or lower-mid 20s Saturday
afternoon.
Saturday night and Sunday, as a surface ridge axis slowly
approaches, the air mass will further dry out, with any residual
flurries diminishing during the second half of the weekend.
Although there will be less wind, it will still be quite cold
for early-mid March, with lows Saturday night in the single
digits and teens, and highs Sunday in the upper teens and 20s.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
2 pm update... Winter should continue to hang tough next week,
with a persistent large-scale trough over the eastern CONUS and
ridging across the western states.
The main system of interest is Monday night-Tuesday, when a
northern stream short-wave amplifies into the long-wave trough
axis across the eastern U.S. and helps a strong coastal storm
develop. Although current indications are that the heaviest snow
will remain well to the east of CNY/NEPA, tied to the rapidly
intensifying surface low offshore, some snow is still likely for
our region, tied to the strong upper-level trough. Stay tuned
for further details over the next few days.
Later next week, temperatures should remain below average, with
a persistent NW flow of cold air. Also, the usual lake-effect
/lake-enhanced snow showers and flurries which accompany these
types of patterns should last through at least Wednesday.
&&
.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
Mainly VFR this afternoon with the exception being KRME where
brief MVFR conditions will be possible for the next hour or
two.
For tonight, a low pressure system will move by to the south and bring
a period of snow overnight into early Friday morning for KAVP.
Expect predominate IFR visbys with period of below alt. min
visbys possible. The low has trended just a bit farther south so
at this point only expecting some unrestricted flurries for
KBGM/KELM with dry weather / VFR for remaining sites to the
north.
For Friday, snow moves out with a low VFR deck predominating.
There will likely be some flurries around but at this point
confidence not high enough to include in TAFs.
Gusty W/NW winds 10-20 gusting up to 25 knots this afternoon
diminishing by this evening. N/NW winds overnight 5-10 knots or
less. NW wind pick up again Friday with gusts up to 25 knots
possible by Friday afternoon.
OUTLOOK...
Friday afternoon through Sunday...Occasional restrictions in
snow showers are most likely to occur at KSYR and KRME, with
mostly VFR elsewhere.
Monday...Mainly VFR. Some restrictions in snow could develop
late in the day, especially KELM, KBGM, and KAVP.
Monday night - Tuesday...Chance of snow with associated
restrictions as a coastal storm moves by to the east.
