Syracuse, N.Y. -- A blizzard is hitting the Tug Hill region today, with heavy lake effect snow blown around by winds approaching 50 mph.

“Visibility is about 100 yards, I would say,” said Chris Skipper, who lives between Constableville and Highmarket, just before noon. “It’s been that way for a while. It’s snowing pretty darn hard.”

Blizzard conditions are defined in part by visibility less than a quarter of a mile, or 440 yards, with winds of at least 35 mph, for at least three hours.

Four to 6 inches had already fallen by 11:30 a.m., said Stan Kraeger, who lives in Constableville.

Here’s a look at photos and videos from people in the middle of the storm today.

One nice thing about having a meteorology school in the lake effect zone is there are lots of students who love weather and love posting about it on social media. One of them is Kaitlyn Jesmonth, a SUNY Oswego student from the Albany area.

“Trying to walk to class and not being able to see the building you were going to was crazy,” said Jesmonth, in her first year at Oswego. “We’ve been waiting for a good lake effect event, and we finally got one."

Afternoon classes were canceled today, and the college has already announced there will be no classes Friday. Here’s a batch of photos and videos from meteorology students.

Update on my way back from class: Heavy lake effect snow has been developing and persisting for the last hour or so with whiteout conditions. A very dangerous situation so avoid travel!! #nywx @PaulCaiano pic.twitter.com/3qvarAfjc9 — Kaitlyn Jesmonth (@wxkaitlynj) February 27, 2020

A few years ago, New York state launched the mesonet, a network of 126 automated weather stations that record reams of weather data every five minutes. Each of the stations has a camera, and here they’re showing the combined effects of snow and high winds.
