Has anyone seen any LONG range forecast for the northern parts of the US?

The weather has been below average temps here in Upper Michigan.. I just checked the extended forcast for sept, and it says highsthe middle 50's and lows in the 30's for the rest of Sept.. Thats cold compared to the usual weather..

I wonder what OCT has in store?? SNOW???
Last year i was hunting in 80 degree weather.. What a change.
