The big dome of heat that had dominated the Great Plains, the Great Lakes and the eastern part of southern Canada was pushed out yesterday by an unseasonal "Alberta clipper", bringing late-September temps with it. The heat is now pushed to the west, with red-flag warnings over much of Wyoming, Idaho and Nevada, and excessive warnings in much of the rest of the west. Fall migration appears to have begun, with shorebirds and a few warblers showing up in the Great Lakes and Great Plains.
