Mammoth Mountain Weather Forecast & Discussion

November 4th, 2022 @ 2:35 PM – The Mammoth Weather Story – A Winter Storm Warning is in place now from Sunday at 4 PM into 4 AM on Wednesday.

Expected Snowfall Amounts from the next system are as follows: Main Lodge and Chair 1 will be in the 2-3 foot range with 3-4 feet possible over the top of Mammoth Mountain. The EU model has 30% higher snowfall amounts from this next snowfall event.

If you’re going to be out on Mammoth Mountain on Saturday expect a morning low in the upper 20s with mid-day highs in the upper 30s to low 40s. Skies will be pt cloudy with winds out of the SW increasing to 25-35 MPH during the afternoon hours.

By Sunday there will be cloudy skies with a 50% chance of snow showers it’s possible Mammoth Mountain could receive several inches of snow during the afternoon hours.

Sunday Night into early Wednesday you can expect snowfall and it will be heavy at times with gusty winds and possible blizzard conditions above 7500 feet.

Down on 395 travelers can expect snow to also be heavy at times after midnight on Sunday right into Wednesday night. My advice is to call it a Red Day and stay home until this next system clears for traveling on Wednesday. The snow on 395 is going to be thick and wet so have your tire chains ready and be ready for slow going.

If you plan on skiing or riding on Monday and Tuesday I doubt much of anything will be open. Maybe chair 6 will be able to spin, whatever the case it’s low tide so wait to ride once this one has passed the area. Live to ride another day.

Mammoth Mountain Weather Discussion & Data

11-4-22 @ 2:11 PM – The next 10 days are highlighted by a large intense low that will be dropping out of the Gulf of Alaska and right down the coast of California and then right over the Sierra as it heads east late on Wednesday.

There is a  break with some weak dirty ridging for Thursday in Friday 11/11 and then a second weaker system comes in for the following weekend. Confidence is high in the first system and low in the second.

As the first deep low comes into our area the exact path the low eventually takes will determine of much snow Mammoth Mountain picks up. This systems track looks just right for Mammoth Mountain with lots of orographic lift.

To recap as of 11-4 the forecast is for around 2-3 feet in the (Main Lodge area / Chair 1 Area) with 3-4+ feet possible over the top.

Temperatures will plummet again next week for ideal snowmaking conditions.

Let’s hope and pray there is enough new snow to ski down to both Chairs 2 and 4 for easier access to the hill this month.

Forever Hope full the Mountain Will Be Buried Again Soon, Snowman

Here is the EPS Ensemble Model going out 16 days.

November into March Mammoth Weather Trends

10-5-2022 @ 11 AM – The new run of the EPS Seasonal is out and it continues to show the trend of an average to above-average winter for snowfall. Each run has been getting a bit wetter and this month’s run is the best looking yet.

Of course, now it has to pan out over the next 6 months and this data is no guarantee Mammoth Mountain will get dumped on. Last year at this time the only wet month the seasonal EPS had on this date was December and the rest showed red and dark brown drought colors.

So good vibes moving forward as we start the snow and cold air watch now.

Who Are We?

Steve Taylor – Mammoth Snowman – Over the last 30+ years, Snowman has spent countless hours studying and learning about Mammoth Mountain Weather and Snow Conditions first hand. He has been skiing around the hill with marked ski poles since March of 1991 so he can measure the fresh snowfall amounts out on the hill. 

Snowman started blogging this information back in 1990 on the old Mammoth BBS system, then the RSN Forums and then on to MammothSnowman.com in 2004 with Video & Photo Blog report. (No YouTube back then). Facebook got added to the fold back in 2008 and then the Facebook Group in 2016. 

Reports, videos, and photos from the website have been featured on both local TV Stations here in Mammoth, along with AP, Fox, ABC, CBS, and NBC News.

Ted’s Bio: Ted has been a full-time Meteorologist (CCM) for the past 25+ years. He has always been fascinated with the weather,” skiing was just a natural extension of my love for snow and rain. I started skiing at age 5,  first discovered Mammoth in 1979 as a youth, and have been a regular visitor since the late ’80s.”.
