Pretty much all she wrote with this one....
Nws now has kfzy up to mid 30s tonight and rain..
Wednesday, a blustery day is in store with scattered to numerous
snow showers along with a continued biting wind still gusting into
the 40-50 mph. This will produce some blowing snow conditions, with
blowing and drifting snow east of Lake Ontario. Accumulations will
be fairly manageable for this time period, but the blowing snow may
result continued issues surrounding transportation. With slow and
steady cold air advection, temperatures won`t change much from the
morning`s lows. This will result in most areas remaining at or below
freezing.
During the afternoon, a lake effect band should be taking shape over
Lake Ontario with a weak upstream connection off of the slushy Lake
Erie. This should slowly move east toward the entrance to the St
Lawrence river in the afternoon and possibly move into Watertown
toward the end of the day.
Wednesday night, the main feature of interest will be on the
mesoscale with a lake band slowly moving south across the Eastern
Lake Ontario region. It should end up ESE over Oswego County, but
synoptic moisture will be moving east away from the region with a
corresponding lowering of the boundary layer capping inversion, the
event may not have lasting intensity to carry it through the night.
Will extend the winter storm warning through Wednesday night for
Oswego as the synoptic event transitions to lake effect.
