Forecast Clues through Christmas

Just got back from visiting my in-laws down in N.C.. The drive down was decent, but the way back was a very long 10.5 hours. Ready to hit the hay very soon.

This is my latest interpretation of the ECMWF weekly long range forecast output into the 4th week of December.

Looks like a much drier pattern setting up for BC over the next 8-15 days as a ridge of high pressure builds over the northeast Pacific and blocks Pacific fronts from hitting BC. Since the ridge will be fairly flat with not much amplitude Pacific air will be able to stream over the top and into Canada.

Still no signs of any blocking across the north through mid-Dec, which would force the cold farther south and east into southern Canada and most of the U.S.

The overall pattern continues to support a strong influx of Pacific air into central Canada and most of eastern North America, while the Arctic air stays trapped over Alaska and northern Canada.

While there will be some pushes of cold air into the central and eastern part of southern Canada and the northern U.S., it will likely be short-lived as the cold comes in and then quickly retreats.

After reading some comments and email I have decided to set up a twitter account for this blog. Should be fun during winter storms.
