Recreational Weather for Mammoth Mountain and Eastern Sierra
August 10th, 2022 @ 4 PM Hey everyone, expect a break in the productive T Storms until possibly next Tuesday when the monsoonal flow looks to return with a nice moist flow once again.
The next 4 days look perfect and that includes your upcoming weekend. No insane heat waves on tap just some average summer mid-August highs and lows.
With all the rain everything has really greened up. Come on up for an adventure soon if you can.
Here is what to expect weather-wise over the next week.
Thursday into Friday: Expect clear skies with highs at the resort levels 8900 feet in the upper 60s to low 70s with early morning lows down into the low 50s. Winds will be southwest 10 to 15 mph, with gusts as high as 25 – 30 mph over the higher elevations. Down in Bishop highs will be in the mid-90s with early morning lows in the low 60s.
The Weekend: Looking mostly clear, the EU model wants to start to bring back some build-ups by Sunday.
Officially the forecast is for clear all weekend, with highs in the low 70s at the Resort Level 8900 feet and mid to upper 70s in Mammoth Lakes with early morning lows in the 50s. Down in Bishop highs will be in the mid-90s with early morning lows in the low 60s.
Next Week: As of now a return to the moist monsoonal flow will return, not looking like much rain, but locations that come under a well-developed storm could see a quarter inch or more of rain. Let’s hope the projected moisture increases as next week approaches.
**When Thunder Roars Go Indoors** If you get stuck out on a hike or ride in the Thunder Storms here is some information on what to do.
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.

Looking at the model run below it goes almost out the start of Fall and there are still none of what I call the death ridges in site for the West. It does look like more muggy days and then some warmer and dry Summer days are left.
But still, no extreme high pressure ridges like we have seen the last two years. There is still time for that to change but at this point, I would not expect the Summer to end anything like the last 2 years.
The big question at this point that nobody wants to really talk about today is how will the wildfire season in California play out before the first snows fall.
As long as the Monsoonal flow continues with the wet storms the chance for big fires will be suppressed. What happens after that gets cut off is anybody’s guess.
On the model run below we do see a monsoonal flow still in early September so let’s hope that flow remains nice a wet.

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.
