Another potent winter storm is winding up to lower the boom on Western Pennsylvania. Light snow will begin to fall Tuesday afternoon and increase in intensity later Tuesday night before blizzard-like conditions unload on the Pittsburgh area Wednesday morning. Temperatures will drop to the teens and eventually single digits as sustained winds of 20-30 mph howl. This increases the danger for further power outages and damage to personal property. The weather on Wednesday should not be taken lightly. The storm slows down Thursday and into Friday with some trailing snow showers. I expect the Pittsburgh metro area to receive 8-14" of fresh snow.
I'm sure you've heard about the Blizzard of 2010 by now. It is long gone, but the damage has certainly been done. Hundreds of thousands lost power due to the weight of the wet, heavy snow. Some areas received over 3 feet! Colesville, MD took the prize of the most snow with 40". Unfortunately for storm-weary Mid-Atlantic residents, another storm may impact the region during the middle part of the week, bringing more accumulating snow! This one may track a bit farther north, impacting New York City and Southern New England as well. As always, the exact track determines how much snow falls. It'll be a fun one to track.
