Been watching this event from afar.. Just because I love lake effect lol
A Pacific-based shortwave trough will track across the Central and
Eastern Great Lakes Tuesday night into Wednesday. Winds will become
southwest ahead of an approaching cold front and cold air advection
with 850mb temperatures falling to around -6C will filter across
Lake Erie and Lake Ontario by Wednesday morning. This will likely
initiate a lake response beginning northeast-east of the Lakes. Lake
temperatures are currently in the mid 40s which offers marginal lake
instability during this time. Daytime highs are expected in the mid
to upper 30s so any snowfall accumulation during the day will be
limited. The cold front will move through the region from west to
east by Wednesday night and west winds will drag colder air into the
region. The mid-level trough will be moving into New England and
moisture will be diminishing quickly across the region. There will
likely be a short window of upstream moisture and lake induced
instability to get accumulating snow in some places. At this time,
lake effect snow showers will likely be confined to the higher
elevations east of the Lakes into Thursday. Warm air advection and
high pressure tracking to the south will end snow showers Thursday
night into Friday.
