Welcome to MammothSnowman.com – Snow Season 22-23

December 28th, 2022 @ 8 AM – Good morning, the first base storm has passed thru the area leaving 2-3 feet of heavy wet snow from 9000 feet up. Today’s break in the action should allow the entire hill to open by mid-day with the top being the last to pop.

Currently, up top, the temperature is 12 degrees with an SW wind at 14 MPH gusting to 25 MPH with 37 inches of new snow at 11,053 feet. Down at Main Lodge, the temperature is 21 degrees with an SW wind at 15 MPH gusting to 21 MPH with 26 inches of new snow that has 3.51 inches of water content.

Mammoth Mountain Weather: There will be a break in the snowfall today before the next wave of moisture hits early Thursday – Saturday night.

If you’re out on the hill today you can expect pt cloudy skies with gusty SW winds to start the day. It’s expected that the skies will clear out later this morning and winds will shift to the northwest wind at around 20 mph, with gusts as high as 35 mph – 45 MPH over higher elevations.

Temperatures on the hill will be in the low to mid-20s so layer up again the warm days are over.

Mammoth Mountain Snow Report

12-28-22 @ 6:12 AM – Lots of fresh heavy wet snow out on the hill from yesterday’s weather system. The forecast of 20-30+ inches was spot on.

The snow that fell was mostly heavy and wet, this stuff skis and rides great when it’s falling and then tends to set up once the front passes.

Go wide today and beware of the thicker snow that’s set up in wind-exposed sections of the hill. 22 will be the call first thing this morning as it ran yesterday around 2:30 PM.

Up Top expect Avy control to take several hours so most likely mid-day before you can get up G2 and chair 23. Everything is still clouded in at 6 AM, but as stated above skies are expected to clear out at some point.

Enjoy the hill if you’re blessed to be out there today.
