Yeah, according to the NWS the band *should"drop south after midnight.. Flow 280ish which will once again keep me on the fringe lol I think we need a 275 ish here.. Good luck..
A persistent cyclonic flow will circulate colder air across the
region through tonight...with H85 temps falling to arnd -12c this
evening to -15c by Wednesday morning. Additional support will come
in later this evening as shortwave over western Great Lakes makes
its way eastward. This will maintain significant lake snows east of
the lakes where lake snow warnings remain in effect into Wednesday
morning. The steering flow will veer from roughly 260 this evening
to 280 after midnight, then to 300 on Wednesday when the region will
be found in the H85 thermal trough. While this sub arctic airmass
will tend to expand the lake snows over the region (largely due to
spray off Lake Ontario)...a crashing cap will leads to MUCH less
efficient snow-making southeast of the lakes. Even so, much of
western NY to the Finger Lakes will pick up a couple inches of snow
on Wednesday.
