So I read the KBUF AFD this morning, specifically the long range for friday through next Monday. The discuss the perfect set up for cross polar air die to a +PNA and Greenland block supercharging the air as the PV drops to the northern Great Lakes! They state this will have lasting power through the foreseeable future too!!! Elaborate then why the next 3 systems after that all cut west of us giving us rain instead of snow?!?!?!
