While historical lake-effect snow wrapped up Thursday over the eastern Great Lakes, a new round of intense lake-effect and local blizzards are poised to slam downwind areas in the wake of a major weekend snowstorm.
Some areas in the traditional snow belts could have snow flying for days starting late Sunday and lasting into the middle of next week.
An additional 1 to 2 feet of snow seems likely with local amounts pushing the 3-foot mark all over again. Confidence is "high" with the AccuWeather.com lake-effect snowfall forecast.
Combine the heavier, somewhat wetter snowfall from this weekend's storm with the new snow and there is the danger of roof collapses and people getting stranded in deep snow.
Strong winds will drive the new snow around into huge drifts, which will create uneven loads on some roofs and could require very heavy duty snow removal at the local level.
We could be looking at over 3 feet of snow on the ground in a broad area downwind of the Great Lakes and locally perhaps a snowpack of up to 10 feet in some locations.
Corry, Pa. in Erie County as of Friday morning has a snowpack of 39 inches on the ground and they could experience additional accumulations Sunday through early next week which will be measured in feet.
As with the lake event early this week, snow squalls could reach 100 miles or more away from the lake shore areas, hitting some communities by surprise in the Ohio Valley and east of the Appalachians.
According to Expert Senior Meteorologist Dan Kottlowski, "A slightly different wind direction with this event would imply the bands of snow reach new areas and perhaps with greater intensity than the last in some cases."
"For example, parts of northwestern Indiana could get more snow out of the new lake effect event, due to a north-northwest flow," Kottlowski added.
As painful as the cold with the snow was this past week, this one will be worse with much lower temperatures and wind gusts of 30-40 mph in many locations, driving AccuWeather.com RealFeel temperatures to dangerous, if not life-threatening levels to those exposed for long periods of time.
An in-vehicle survival kit is a necessity when traveling in and near the snowbelts in this situation starting late this weekend. Make sure your vehicle is winter ready. If you do become stranded and remain in your vehicle, be aware of the dangers of carbon monoxide poisoning.
