Fair warning...

Whether it's because the models are catching up with Canadian Arctic ice conditions or what, I'm not sure.  But there has been a shift in the modeling with a significant cold press coming down from the Arctic starting next week and going well into December and assumably for the winter.   In terms of relation to averages, the next week and the following will be definitely much colder than normal.  As such, there will be better opportunities for snow rather than rain.  The system on the 28th that I mentioned yesterday is still there but farther south.  It is currently projected to give a pretty good snowstorm to the US NE, with the Ottawa area catching a bit of the northern edge of the storm.
