Mammoth Mountain Weather Forecast & Discussion
December, 29th 2022 @ 11:44 AM – A weak weather system is moving quickly through the area this late morning. There are already 3-4 inches of fresh snow in the Main Lodge area. The front has passed so look for snow showers and gusty winds for the rest of the day out on Mammoth Mountain and down into Mammoth Lakes.
The next upstream disturbance will be into the area overnight / early Friday with more moderate to heavy snowfall at times on Friday. Snow Levels will be high at an estimated 8500-9000 feet. That would be between Main Lodge and down to the base of chair 4.
Snowfall amounts from 9000 feet up from late tonight into late Friday PM and looks to be in the 6-11+ inch range.
This will be lower ratio of Sierra cement snow once again. With that said, this type of snow skis and rides great when it’s falling on a packed surface. I would bet you can get some good fresh thick stuff on Friday, just a heads up.
If you’re out on the hill this Friday expect highs in the low to mid-30s with snow above 8500-9000 feet with a mix of rain and snow down at Canyon and Eagle Lodges. Winds will be moderate to strong at times out of the SW at 20 to 30 mph, with gusts as high as 55+ mph.
On Saturday expect heavy snow and strong winds, looks like most of the hill would end up on weather hold if the storm comes in as forecast, but that’s still a big if at this point in time. We will have an update on the expected outcome on Friday.
On Sunday the jury is still out on when the snowfall stops, could be that it ends overnight or as the ECM is showing there could be more snow showers on New Years’ morning.
Next week the Storm Door is Open, the fine details are not in tune this far out, but it does look like there could possibly be more footage of snowfall with a bit lower snow levels.
Of course, we will keep you updated here on the website. – Snowman
