The Pacific storm track remains highly active with multiple systems traversing northern and eventually southern routes across the U.S while the continent’s cold pool sags south.

A lot of moisture shall pile into California with big low level rains and high level snows.

Huge amount of water for CA within the next 6 days!

Big snow totals also!

In between the lows, it’s cold!

Here’s the late PM temps off the GFS for today.

Tonight sees -20s and -30s in Idaho, Montana and Wyoming.

Yesterday’s national extremes.

A potent snow system running the arctic boundary crossed the Northern Rockies yesterday bringing heavy snow, powerful winds and whiteout conditions. Parts of Idaho, Montana and Wyoming were hit hardest. Today the snow and wind is crossing the Northern Plains.

GFS surface/precip for yesterday (Monday)

Behind the system, arctic air descends over the N Rockies.

Then Plains

Then Midwest at the same time another potent Pacific storm piles into California and Great Basin.

Then finally the East gets cold The next potent storm entering California in the next few days will track further south thanks to arctic high pressure anchored over Montana and Wyoming.

That CA/NV system could be a central Rockies/Plains snowstorm/blizzard late week and through this weekend and eventually cause issues for the South into early next week. A Southeast/Carolina snowstorm followed by arctic blast?

An interesting GFS snow forecast!

In comes another Pacific storm packed with moisture into a cold West.
