This is the only lake effect event comparable--when looking at the temperature parameters--to the current Buffalo event I can remember. It started on October 12, 2006 and finished the next day.
The Lake Erie water temperature was 62 degrees. The air aloft (5000 feet)--the key level for determining lake effect--was -8 celsius (or 17 degrees F).
The temperature difference: 45 degrees from the surface to 5000 feet.
Here were the 2 day totals:
In the current (November 18-19, 2014) event, the lake water temperature in the eastern basin of Lake Erie is between 50 and 54 degrees. The air aloft (5000 feet) was -18 celsius (or zero degrees F)!
The temperature difference: 54 degrees from the surface to 5000 feet!
This eastern basin warm pocket fueled the snow development as the wind paralleled the shoreline before it made landfall south of Buffalo. The key has been the wind direction. The SW wind (now WSW) carried the arctic air directly over the ENTIRE warm pool of water. The fetch over the warm pocket was more than 100 miles! Normally in northern Ohio, the fetch is between 50 and 60 miles from Canada to Cleveland.
