Mid October snow on the way?

The graphic should say it all. It is a pretty interesting time of year. Though the "pretty" part is probably peaked.
It is also a time whebn computer modeling in the northern and southern hemisphere began to take a dive in accuracy. This is in part due to the strongly driven jet stream with higher amplitude troughs or dips and ridges where systems cut off amplify out. Blocking patterns can emerge and modeling though amazing in it's accuracy can be thrown some large curve balls. Curve balls routinely bust forecasts.
