Here’s a close-up view of North America… couldn’t have drawn these maps better myself. Note where the CORES are, AK & Greenland which means Siberian air gets pulled over the pole into the continent.

As for California’s drought… the rainfall of the past month has made for a significant dent!

According to NOAA, much of California has received over 200% normal between Nov 18 and Dec 17.

More detail tomorrow on the impending storm which could become a Great Lakes weather bomb around Christmas.
