We are in the thick of it here at GSM Headquarters!!!

In between is a narrow zone of freezing rain, including around Poughkeepsie, New York, Danbury, Connecticut, and Mount Pocono, Pennsylvania.

  • Snow is expected over the interior Northeast from parts of New York state north of the middle Hudson Valley to portions of New England.
  • Snow is also expected in the Appalachians from eastern Tennessee through western Pennsylvania.
  • Sleet and/or freezing rain is likely from northeast Pennsylvania through southern New York and eastern New England.
  • Much of the snow and ice from Harper will be done with by Sunday evening except in northern New England.
  • Strong winds will buffet much of the East, leading to areas of blowing and drifting snow.
  • Some minor to moderate coastal flooding is possible along the New England coast, mainly during high tide on Sunday morning.
  • A flash freeze is possible in southern New England, from near Boston to Providence, Rhode Island. Temperatures will plummet through the day, freezing any rain or sleet that is on the ground at the time.

  • Parts of upstate New York and northern New England are likely to pick up more than a foot of snow.

Current Snow Cover

Freeze outlook


Ice accumulations sufficient to slicken most roads, at least for a time, are most likely from northeastern Pennsylvania into southern and coastal New England. The combination of strong winds and accumulating ice (in addition to snow) on trees and power lines may lead to at least scattered power outages and tree damage from western and central Connecticut to central Massachusetts, southern New Hampshire and coastal Maine. Worsening the power outage threat, bitter cold will sweep in after Harper departs. Rain may freeze on Sunday in parts of southern New England after Harper pulls away, creating a black ice threat.

Rochester snow totals for January 19 broke record set in 1884

From a record high of 60° this afternoon to a snowstorm just hours later here in Rochester, NY.
Perfect weather as I reach a live coverage milestone tonight at 10:30 PM ET on @weatherchannel

Greater Rochester is waking to a heavy blanket of snow and continued, steady snowfall, with accumulations that set a record for Saturday.

Snow totals from overnight are just coming into the National Weather Service in Buffalo. One of the earliest, a report of 14 inches from Perinton, should be indicative of the area.

“That’s a pretty good representation of what you got — over a foot everywhere,” said meteorologist Bob Hamilton.

Snow plows in the city and towns have been busy, with the city reporting its crews had completed arterial, collector, residential and even sidewalk runs before dawn.

“It’s been coming down an inch an hour,” Irondequoit town Supervisor David Seeley said early Sunday. “We’re just trying to stay ahead of it. Our biggest issue right now is the wind and the drifting (snow). The drifting is just dumping it right back on the main roads.

“The main message is people just need to stay off the roads.”

The area was expected to receive 10 to 14 inches of snow overnight and we will know if we reached that when the National Weather Service releases updated snow totals. Rochester had 8.1 inches as of 1 a.m. Snow accumulation totaled 7.8 inches at the Rochester airport Saturday, which set a single-day record for Jan. 19, said meteorologist Kirk Apfell.

The previous record of 6.3 inches was set back in 1884
