Explaining why the North Country saw the most snow

We'll explain what upslope snow is and why it caused the North Country to see the most snowfall Monday.

Posted: Feb 22, 2021 7:04 PM

Heavy snow blanketed Central New York today, but the greatest accumulation was in the North Country. This is all because of the elevation.

As a system moves in from the west, there's cold air ahead of it. In the Mohawk Valley, our temperatures were right around freezing today. The higher elevation, the colder it gets. This is why the North Country was well below freezing.

Now the reason we saw more snow in the North country is due to elevation and the wind direction. The wind is coming in from the south. As it moves past the Mohawk Valley and into the North Country, orographic lifting occurs.

What this means is that the air is forced to move upward when it hits the mountains. When the air is shoved upward, it squeezes all of the moisture out of the clouds and creates heavy snow over the highest elevations. Overall, the North Country saw the highest snowfall totals.
