It’s official: 2018 has been the driest winter ever for Arizona’s mountain watersheds

Not without good reason, the nation’s media have been focusing on the dramatically thin snowpack of the Upper Colorado River Basin, which portends a meager amount of runoff into the Colorado River system.

Why an enormous, persistent arctic low-pressure system is helping dry out the American SW

It’s… the blob. It came from above. And it’s got the world in its grip.

And… it’s not going anywhere any time soon.

If that sounds like a trailer line for a low-budget sci-fi movie… well, it could be.

But it also fairly describes the powerful “Strong Hudson Bay Low” – an Arctic-spawned low-pressure system that locked in place over much of the Northern Hemisphere in mid-November. The strong, static “blocking” system is showing no sign of releasing its grip any time in the foreseeable future.

SNOWPACK IN THE ROCKIES

Nothing against California, you understand. We’re all delighted to hear about this winter’s bounty of rain and snow, especially as it piles high in the Sierra Nevada.

Love all those “atmospheric rivers.”
