Mammoth Mountain & Eastern Sierra Weather Forecast

Recreational Weather for Mammoth Mountain and Eastern Sierra

Hello and good day, this is your Mammoth Mountain and Eastern Sierra Weather forecast for June 24th, 2022

The window cast shows clear blue skies from Mammoth Mountain to Bishop today. Air Quality in the area remains perfect.

Over the last couple of days, there have been some clouds and build-ups along with a few rain showers. Did not see any lightning strikes or hear any thunder myself as most of the action stayed to the west of the Eastern Sierra.

The next few days look great to get out for an adventure. There still could be an isolated thunderstorm so take cover if you happen to hear thunder.

Temperatures in the high country at 8900 feet aka the Main Lodge and the Mammoth Lakes Basin will be in the upper 60s to low 70s over the weekend.

Lows at night for you campers will be in the upper 40s. Winds over the country will be light except in areas where there is thunderstorm action.

Down in Mammoth Lakes, temperatures will be in the mid-70s with overnight lows in the upper 40s with mostly light winds at times.

For Crowley, Lake highs will be around 80 with overnight lows in the low 50s. Bishop and the Mill Pond areas will be cool in the morning hours and then hot in the mid-90s by mid-afternoon.

Here are the links to the specific highs, lows, and wind speeds for many of the major recreation points in the Eastern Sierra: Mammoth Mountain Main Lodge, Top of Mammoth Mountain, Mammoth Lakes, June Lake, Crowley Lake, Toms Place, Rock Creek Lake, Bishop & Mill Pond, South Lake.

**Locals Tip: As we move into Summer if you’re coming up bring a fan with you if you’re staying in a condo or home. They help big time when it’s warm and muggy in the high country. We have 4 of them along with ceiling fans that run when it’s Summer time. No AC in Mammoth so be prepared.

Have a great day and I hope to see you out on the hill for some Mountain Bike action soon,

10 Day Outlook Model Runs

Over the next 10 days the isolated T Storms will be with us to start and then by Monday ridging will warm the area up to about 7-10 degrees above the average high for this time of the year.

The ridging will be replaced by guess what? Yep more troughing off the West Coast and into the eastern Sierra for the July 4th weekend.

If that comes thru you can expect below-average temperatures for what is usually one of the hotter weeks of the year. Along with the cooler highs at the end of the period, I would expect breezy conditions for the higher elevation starting around next Thursday sometime.

ECMWF Seasonal Ensemble Mean - Next Update 7-6-22

Here is the ECMWF Seasonal Ensemble Mean forecast that goes out 6 months. This model updates once a month with the images coming at around the 5th of the month.

The trend for temperatures over the next 6 months is more of the same with above normal highs. The Fall season at this point looks toasty. Let’s hope it flips over to a cooler solution over the next few months.

I know I am hoping and praying for a nice cold November.

Looking below at the Precipitation Anomaly they have average precipitation right through September. October also looks drier with November even drier before the December run has Mammoth Mountain picking up average to above average snowfall.
