The models are woeful, so let’s use the models. Love also the circular thinking about the jetstream for the Laurentide. Clue for them…look up! 🙂

Climate scientists now put the odds that the American Southwest is headed into a 30-year “mega drought” at 50/50. Meanwhile, the forecast for the Pacific Northwest is continued warming with slightly drier summers and even wetter winters.
However, 21,000 years ago, at the peak of the last Ice Age, a period known as the Last Glacial Maximum, the Southwest was wetter than it is today – much wetter – and the Northwest was…
