this evening in north central NY, with snow and blowing snow
and icy roads possible later this evening farther south into
south central NY into northeast PA.

wind chill temperatures to approach -15 late tonight.
Strong winds will blow and drift the snow around tonight.
Wind gusts to 35 mph later this evening into overnight.
Rapidly falling temperatures will cause a flash freeze
potential late this afternoon and tonight.
Could cause very dangerous travel conditions on area
highways.
Especially south of where the heavy snow is falling at
present.
Risk of multi-car pile-ups.
People could be stranded if this happens.
Very cold conditions could make the situation very
dangerous should this happen. Minor flooding possible in typical flood prone areas.
