Weekend greetings,
Good to hear you've had your first snowflakes, Stewart. it's been a very benign Fall thus far in Southern Ontario, and going by Brett Anderson's take on the latest ECM LRF models this may well continue into December. http://www.accuweather.com/blogs/anderson/story/57967/updated-weekly-computer-model-outlook.asp
The much vaunted pattern-change is being talked of less and less, with even Henry M backing off a switch to cold weather in the east to begin December. In the shorter term it was a straight out GFS v ECM battle in terms of the potantial snowstorm for New England and southern Ontario in the middle of next week (the latter model has been showing the storm). The way things have been going I must say I wouldn't bet against the end result being a damp squib!
However there's certainly some cold air into the west, as Stewart mentioned - the same airmass that was bringing -40c/f readings to Fairbanks, Alaska earlier this week. It's been cold enough for some flurries in Vancouver overnight while sub -20c readings stretch from eastern BC through Alberta and into the Prairies and Great Plains, with a band of accumulating snow heading east through Minneapolis. Nice and snowy in Deadwood, SD this morning: http://www.sdpb.org/webcams/deadwood.aspx
While temps will fall further east it won't be that much below average, and the whole chilly airmass will be shunted east quite quickly so that by Thursday coming it will be relatively mild through much of central North America.
Meantime, what do you think of the Blue Jays new logo Stewart? I quite like it myself.
