Cooler Temperatures this Early?

Temperatures are expected to drop late next week as arctic air moves across the U.S. But why so early? This is most likely directly related to the remnants of Typhoon Bavi or perhaps Maysak, or a combination of both; typhoons which become extratropical in the far northern Pacific region tend to turn the jet stream more “meridional” (poleward), which can result in a large southward surge of cold air from the Arctic into North America. This happened in 2014 as well with Typhoon Nuri, which caused a record cold outbreak across the US and Canada in November of that year. This phenomenon is know as Arctic Amplification.
