The National Weather Service is now calling for as much as 60 inches (152 cm) of snow – that’s 5 ft of snow – to hit Buffalo, New York, in a days-long snowstorm. The town, simply east of Lake Erie, set an all-time record of 56.1 inches (142 cm) in a three-day snowstorm in 2001. This storm may high that.

The Buffalo Bills have been speculated to play a house sport towards the Cleveland Browns at midday, however it’s now going to be at Ford Area in Detroit.

Cities in upstate New York close to the Great Lakes aren’t any strangers to lake-effect snow. This phenomenon is a typical prevalence all through the U.S. Nice Lakes area throughout late fall by means of winter. Lake-effect snow occurs when chilly air strikes over a hotter physique of water (reminiscent of a Nice Lake). Then, the heat and moisture of the lake transfers to the decrease ambiance. In the end, clouds construct and launch snow downwind. Locations on the downwind facet of the Nice Lakes can simply get 2 to three inches (5 to eight cm) of snow per hour.

Lake-effect snow: An interview with Tom Niziol

With this in thoughts, EarthSky interviewed Tom Niziol, a winter climate professional, just a few years again. He mentioned that correct forecasting of lake-effect snow is a problem as a result of:

… [Lake-effect snow] happens on such a small scale, nearly on the dimensions of a summertime thunderstorm. One portion of a neighborhood or metropolis is perhaps beneath heavy snow, the place just a few miles away you might be beneath sunny skies.

He mentioned Buffalo, New York, on the jap shore of Lake Erie, is infamous for its lake-effect snowstorms. Niziol mentioned chilly air shifting in from Canada triggers the snowfall.

As that air strikes throughout the nice and cozy water of the Nice Lakes, warmth and moisture from the lake rises up into that air mass. That moisture ultimately condenses out into snowflakes. And once we get to the downwind shores, we find yourself with lake-effect snow.

As well as, Niziol mentioned related snowstorms occur across the globe. The coasts of the UK, France, Japan and Korea, for instance, get what’s known as ocean-effect snow, from chilly air shifting throughout heat seas.

So at a complete vary of latitudes within the Northern Hemisphere, proper across the globe, we see the identical exercise.

Lake-effect snow causes regionally heavy snowstorms

Niziol additionally gave an earlier instance of how dramatic lake-effect snow could be.

In early December 2010, within the western New York space across the metropolis of Buffalo, one among these snow bands arrange off Lake Erie. The band was about 8 to 10 miles extensive. The northern portion of Buffalo had inexperienced grass all through most of this occasion. The southern portion of Buffalo, nevertheless, solely about 10 to 12 miles away, picked up 40 inches of snowfall.

The timing of seasonal snowfalls

He mentioned that lake-effect snow can start in early fall and proceed all through the winter months.

Early within the fall, we see the identical kind of exercise – chilly air shifting throughout a heat physique of water – however it’s truly heat sufficient that we see lake-effect rain showers happen. As we get into November to early December, the air is chilly sufficient to show that into snow.

However, if the lake freezes over, it might convey a halt to those seasonal snowstorms.

Lake Erie is a really shallow lake. In January it develops a big quantity of ice cowl. The ice cowl acts as a cap, in a easy manner, to restrict the quantity of warmth and moisture that may come by means of that ice after which modify that air mass.

Smaller lakes freeze over and lower off the availability of heat wanted to kind clouds and lake-effect snow. Picture by way of NOAA.

Easy methods to put together for lake-effect snow

Most significantly, Niziol mentioned that individuals who expertise lake-effect snow ought to know find out how to be ready for an surprising snowstorm.

Be ready for winter climate situations. Have further garments in your automotive, ensure that your cellphone is charged, have a shovel within the automotive, some water, granola bars, further meals as effectively. Since you by no means know whenever you depart the home, even in case you have a forecast with you, what it will likely be like whenever you drive by means of one among these snow bands.

Within the U.S., lake-effect snow belts could embrace parts of the Higher Peninsula of Michigan, northern and western parts of the Decrease Peninsula of Michigan, northern Indiana, northeastern Ohio, northwestern Pennsylvania and western New York state.
