Cold weather has become pretty common around here! Today the high temperatures in Portland didn't get out of the 30s. And this past Sunday, highs didn't get out of the 30s, either. In fact, it was cold enough for a little light snow. Not quite as much as in this picture, but still, it was something. =)

So where is all this cold air coming from? Numerous storms have been dropping down from the north, and dragging that cold air down along with them. And it's probably part of a larger pattern. With La Nina in place, more unseasonbly cold weather can be expected throughout the winter months.
Will we have a white Christmas? Historically, there is less than a 25% chance that there will be some snow on the ground on Christmas day. But with unseasonbly cold weather expected...that probability may be increasing this year. Guess we'll have to wait and see! =)
