From midday onward, snow will mix with or change to sleet and freezing rain from south to north (taking until late afternoon-evening for NY Thruway
northward). A wintry mix will continue through Tuesday night.

Gusty winds on Wednesday combined with the weight of ice on trees/lines could lead to power outages. 

  • Snow heaviest along-north of NY Thruway corridor. 3 to 7 inches of
    snow possible farther south across the rest of Central NY-Northeast
    PA; uncertainty in amounts due to how much ice may mix in.
  • Freezing rain amounts of around a tenth of an inch possible across all
    of Central NY and Northeast PA; as much as a quarter inch for the
    Poconos-Catskills.
  • As storm leaves Wednesday, 30-40 mph wind gusts expected. This
    along with the weight of ice on trees may lead to a few power outages.

Travel will be difficult with several inches of snow likely and a glaze of ice from freezing rain. High pressure will move through the area Thursday before another storm moves into the area on Friday.
