All I’m hearing is “higher elevations “
yet they have 12”-18” Down to parish..
THURSDAY/...
Complex forecast this period. Consolidated surface low near the New
England coast Tuesday will rotate slowly into northern New England
by Wednesday. On the western side of the low, colder air will build
into the area during the day Tuesday. 850 mb temperatures just cold
enough to support snow, especially across the higher terrain.
Favorable moisture profiles, a westerly fetch and upsloping will
maintain steadier snows east of the Lake Erie and Lake Ontario. Snow
ratio should be rather inefficient for accumulating snows across
lower elevations, with better ratios across the hills south and
east of Buffalo and over the Tug Hill. Expect 2-3 inches of snow
across higher terrain east of Lake Erie with 3-5 inches
possible on the Tug Hill. Elsewhere, snow showers should only
accumulate an inch or so.
Tuesday night into Wednesday night, thermal profiles do not change
all that much with 850 mb temperatures remaining around -8C.
Boundary layer cooling improves, but it continues to look like
a combination snow event having both a synoptic and lake effect
component with some lake and orographic enhancement. Upslope and
lake components will play a big role with significantly more
snow expected across higher terrain although there should be
some snow accumulation in all areas. Lake enhancement could
bring locally high amounts east of the lakes during this time.
These areas could see localized amounts of up to a foot.
A Winter Storm Watch remains in effect east of Lake Ontario. Greater
forecast confidence has been gained to issue a Winter Storm Watch
east of Lake Erie.
Lake effect snow will continue Wednesday night, but snowfall rates
will diminish. Several inches of new snowfall will be possible
across higher terrain due to upsloping. Snow showers will then
linger Thursday, with only light additional accumulation expected.
This long-term snow event beginning late tonight and lasting into
Wednesday night will likely produce some fairly impressive storm
totals. Due to the marginal thermal profiles, the greatest
amounts should be across higher terrain, but accumulating snows
are likely just about everywhere.
