.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
An active pattern lies ahead for the long term period with two storm
systems looking to impact eastern New York and western New England
with winter precipitation. Though details remain moderately
inexplicit, the first system is expected to first show influence
over the region by Saturday night, likely bringing light to moderate
amounts of accumulating snow. The second, more complex system whose
details contain even more ambiguity, looks to grace the region
Tuesday evening. This storm could also inflict measurable snow
across the region, but based on recent guidance, could be more of a
wintry mix type of event. Read on for details...
Saturday night through Monday...High pressure ridging over eastern
Canada begins to push eastward as an open wave with numerous pulses
begins to take shape over the northern Midwest, Great Lakes and Ohio
Valley region. Simultaneously, a low pressure system, having
originated in the Southeast, finds itself centered in the Carolinas
along its northeasterly track up the Atlantic Coast. Throughout
Saturday night into Sunday morning, the low will progress further
into the Delmarva, becoming situated just off the NJ/Long Island
coastlines after midnight. Of course, being several days out at this
point, there remains a decent amount of uncertainty surrounding the
orientation of this track as well as the timing, but model guidance
seems to be in fair agreement in this solution at this time.
With cold air having been ushered into the region in response to the
prior passage of a cold front, upper-level jet dynamics and
increased confluence at the surface to support lift and southerly
flow aloft to support plenty of moisture advection, light to
moderate snow is becoming an increasingly likely result of the
passage of this system. In addition to the temporal and evolutionary
uncertainties of this system, there remains a fair amount of
uncertainty in the amount of snow that will be accumulated and which
areas can expect the most. At this time, the axis of heavier snow
appears to be south and east of the Capital District. However, based
on the latest guidance and ensembles, it would seem that much of our
area will see measurable snow that could meet at least Advisory
criteria. Will continue to monitor the situation closely.
This will be a relatively fast moving system. Most of the snow looks
to fall overnight Saturday into Sunday morning. With the coastal low
still within reach of influence, however, snow could linger
throughout the day Sunday especially in western New England. Snow
from this coastal low will taper off by Sunday afternoon, however, a
secondary low pressure system beginning in the northern Midwest
Saturday night will slowly track north and east into southeastern
Canada through Monday which could help to generate some lake-induced
snow showers especially in the SW Adirondacks. Minimal additional
accumulations are expected.
Tuesday through Wednesday...The second system of interest for the
long term comes potentially Tuesday evening through Wednesday. A
fairly potent low pressure system looks to track toward the region
from the Southern Plains after becoming closed off from originating
as an open wave in the southwest CONUS. The main low looks to weaken
along its northeast track through the central U.S. while a secondary
low looks to form near the eastern Great Lakes. While antecedent
cold air could certainly allow snow to be the preliminary
precipitation type, but an influx of warm air could force the change
over to rain or additional wintry precipitation types. These details
are still very ambiguous at this point being a week out. However,
this will be another system that will monitor closely going
forward.
