Well Pittsburgh saw today another rain storm that would turn into a blizzard. In the last few days we've accumulated nearly nine inches of snow. While we don't have the sunny days that Denver has which melts all their snow by afternoon, nor do we have the persistent snow that lasts till April like in Ottawa, Pittsburgh's weather is mostly unique across the US.
Since Pittsburgh sits on the western side of the Allegheny Mountains, humidity and nasty weather can build up before dumping it on the city. Pittsburgh doesn't endure tornadoes, hurricanes, earthquakes, droughts or even insect swarms that affect most of the US.
Pittsburgh can have very difficult winters where temperatures can drop below zero, dump feet of snow and cold temperatures can last nearly 6 months.
There are reports that even Seattle, WA now has more sunny days than the 'burgh. That's all well and good. While most of the city would love to have 300 days of sun like Phoenix, we do have the snow. The sleds, skis and snowboards all come out of the closet, which also brings out the kid in all of us.
