Mammoth Mountain Weather Forecast & Discusion
12-29-24 @ 8 AM Updated …HIGH WIND WARNING REMAINS IN EFFECT UNTIL 7 PM PST THIS EVENING… Southwest winds 25 to 40 mph with gusts up to 70+ mph…
Today’s Weather Summary: The next in a series of weakening low-pressure systems will bring a chance of snow showers. Winds will increase during the early morning hours, creating more wind holds on Mammoth Mountain.
Snowfall on the hill looks in the 3-5 inch range, with 1-3 inches possible in Mammoth Lakes. On Highway 395, expect a dusting of snow at best, with a mix of rain and snow and strong cross winds from Toms Place up to Mammoth Lakes.
If you’re out on the hill today, expect cloudy skies with snow showers in the late morning and afternoon hours.
Temperatures at the first chair will be in the upper 20s to lower 30s, and mid-day temperatures will be in the low to mid-thirties from Canyon Lodge to Main Lodge, with the mid to upper 20s over the Top of the Mountain.
The wind from Canyon Lodge up to Main Lodge will be out of the Southwest at 25-30 mph, with gusts as high as 40-45 mph. The wind over the mid and upper Mountain will have gusts in the 45-65 MPH range by the afternoon hours.
For Monday, expect mostly clear skies. Temperatures at the first chair will be in the teens, and mid-day temperatures will be in the lower to mid-30s, with mid to upper 20s over the Top of the Mountain.
Winds on the lower mountain will be southwest around 10 mph. Over the Mid and Upper Mountain from 9500 feet up, winds will be southwest at 15 to 20 mph, with gusts as high as 35-45 mph.
Weather Outlook for the upcoming week.
A ridge of high presure moves for the start of 2025, bringing several days of bluebird skies Monday onward and lighter winds by midweek to Mammoth Mountain and the Eastern Sierra region.
The ensemble models now show the next chance for light snow and increased winds for New Year’s Weekend.
Looking at the extended fantasy outlook out through the first 10-15 days of January, it looks like Ridge City, for the most part, with well below-average snowfall expected.
Over the years, patterns like this have lasted about two to three weeks. Some snowfall can sometimes sneak in, but it would not be much in most cases.
The longer-range ECM weeklies do have some decent snowfall after that, but confidence in any change or snowfall that far out at this point is low.
Based on past winters like this, I expect January to be drier than average, with near-normal snowfall possible in February and March. Yes, I’m optimistic that this will be another back-end winter, but who knows? Nobody…
Forever Hopefull for More Snowfall, Steve Taylor – The Mammoth Snowman
