Well it looks like the system that was threatening snow for us by Tuesday is going to track further north, bringing accumulating snow to central MB and not much south. The storm track has been bringing most systems and snowfall through central MB over the past week, and it looks like this trend will continue this week. As result, Winnipeg may stay snow free all week, and possibly through Grey Cup weekend. In fact, at this point, Grey Cup Sunday is looking pretty good in Winnipeg with long range ensembles pointing to a good chance of dry weather, along with temperatures of between 0 and -5c for game time. Let's see if that forecast holds as we get closer to the weekend.
By the way, I've added links to the NAEPS ensemble map products recently added to EC's weatheroffice page. This is a joint forecast system between Canada, the US and Mexico to come up with more accurate (or perhaps less inaccurate is a better way of saying it) and more consistent long range forecasts over North America. They have some interesting products and charts which may provide a little more insight into how the weather may (or may not) evolve over the next couple of weeks. These EPS product links are found under Rob's Obs "maps" and "forecasts" drop down menus.
