Hmmm… The times I’ve checked, weather.com (aka The Weather Channel, which is not the same thing as The Weather Network) tends to have some of the more accurate forecasts out there. Of course, nothing a week or more out is all that accurate….

You can always tell those ensemble snowfall maps have a serious resolution issue after day 5 or 6 or so.

If one could explain this would be appreciated l know it's something to do with phases so is it good bad or indifferent.

You don’t know your MJO roundy plots and atmospheric angular momentum. Back to school for you.
