It’s summer-like in the East, but winter-like in the West.

The see-saw weather pattern bringing record-challenging warmth in the eastern U.S. is bringing exceptionally cold and snowy conditions in the West.

Heavy snow has fallen in the high altitudes of central California, northern Nevada, western Montana, eastern Idaho, western Wyoming and Colorado and even into the Arizona high country.

The snow in drought-stricken California was welcome.  “An omen? A godsend? Describe it as you like, but it’s shaping up to be a November to remember for California ski resorts, at least two of which are opening early after recent storms,” the the LA Times wrote.

The higher elevations of Mammoth Mountain in central California were blanketed by 3 feet of snow early this week.

To the north, Montana’s Big Sky Resort reported it picked up 20 inches of powder mid-mountain.

The chilled high altitude air even facilitated the white stuff at much lower latitudes. A blanket of 5.3 inches has fallen in Flagstaff, Ariz. today, the most on record for the date.

As low pressure develops over eastern Colorado in the next day, the heaviest snow is predicted on its backside from western Colorado’s San Juan mountains to southeast Wyoming, where winter storm warnings are in effect.

By Thursday, most of the mountain peaks in the intermountain West will have a fresh covering of snow.
