Mammoth Snowman Weather Forecast

Good morning it’s Tuesday, June 1st, 2021 @ 7:49 AM Hello, and thanks for stopping by my Weather Forecast Center. Today’s window cast is showing clear blue beautiful skies from Mammoth Lakes to June Lakes and down to Bishop. 

Checking in on current conditions this morning, at the top of Mammoth Mountain (11,053 Feet) the temperature is 49 with an ENE wind at a steady 15 MPH. At the Main Lodge and up in the Mammoth Lakes Basin the temperature is a balmy 58.

Down in Mammoth Lakes, the temperature is 57 with calm winds. In Crowley Lake, the temperature is 58, and down in the Bishop / Round Valley areas the temperature is at 66. 

These are by far the warmest morning temperatures we have seen so far in 2021. 

Forecast for the Eastern High Sierra from Bishop to Mammoth Lakes and over the Inyo Forest High Country

Summary: A ridge of high pressure is over us at this time. The ridge is expected to be slowly progressive and will move to our east by early Friday. 

While the ridge moves thru the result will be continued warming with possible record high and low temperatures. 

Along with the heat, there will be some increased moisture for a chance of Thunderstorms on Wednesday and Thursday. 

By Friday a cut-off low will be dropping down the California coast. Its forecasted position as of today would allow for Thunderstorms to develop again on Friday for the higher elevations above Bishop to Mammoth and up to the June Lake area.

For next weekend expect much cooler conditions with increased SW winds under mostly clear skies. 

So a real taste of Summer heat and thunderstorms the next few days and then a nice cooldown. 

It does appear that next week’s weather will be more of the cooler and breezier late spring type of weather we all enjoy during June in the high country. 

Forecasted Temperatures This Week

For Mammoth Mountain at Main Lodge and the Mammoth Lakes Basin (at the 8900-foot level).

Highs will be in the low to mid-70s with nighttime lows in the upper 40s to low 50s through Saturday. 

Mammoth Lakes (at the 7900-foot level) will be in the upper 70s to the low 80s with lows in the upper 40s to low 50s. 

For Crowley Lake and Long Valley (at the 7000-foot level) highs will be in the mid-80s with night times lows in the low to mid-50s.

Down in Bishop and Round Valley highs will be in the mid-90s. Looks like they will miss hitting the century mark at this point. 

Air Quality and Fire Weather Watch

So far the air quality is perfect from Mammoth Lakes down to Bishop and in all the backcountry areas above us. 

Most of California is clear however I can see a couple of fire starts several 100 miles to our west on the satellite view. 

Currently under fire restrictions, the Town of Mammoth Lakes and the Inyo National Forest.

There are no Campfires, BBQs or Smoking allowed now out in the open. Even if you have a fire permit, it is not valid again this season.

Steve Taylor – The 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.
