Forecast details at the bottom of this post
A gusher of precipitable water in the atmosphere spewing from the Pacific, seen in this image from the Cooperative Institute for Meteorological Satellite Studies, has hosed almost the entire West Coast. Click on the image for an animation of the gusher. (But beware: It’s a memory hog!)
The gusher has triggered heavy rain in Southern California and into Arizona. Meanwhile, cold air pouring down from the north has triggered snow pretty much throughout the interior West, including Northern Arizona.
Below is a map with the weather warnings for the West, posted by the National Weather Service. Wherever you see pink and orange expect extreme winter weather.
The forecast for the next few days?
Snow will move east, with a 99% chance of continued shouting about climate change.
