Weather is not climate....and when the Pacific PDO shifts ...so does the weather.
Small cell size forecasts are limited....but if you understand that the general wind pattern for North America is west to east ...you can SEE what's coming.

We timed our ride from Victoria to Toronto and aside from catching up with the system in Chicago for a couple hours...rode without weather issues. You should know what you are saying is utter nonsense.
There are uncertainties...for instance when La Nina will form up as ENSO development is not completely understood.
When we get a strong El Nino in the Pacific as we did last year -the local climate in the Eastern US will show flows up from the Gulf as it did ....just about all winter.
There is still a lot of heat in the system as a residual of that ( we had 38 days so far above 30 C - that's twice the average ) so a warm fall is expected but a lot will depend on the jet stream strength as to whether we get an early polar outbreak in the east.....
