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

Weather Summary

We have had some nice cool weather in the area from a trough of low pressure that has dropped down to the central California coast.  That low will lift to the NW over the next 24-36 hours.

Then heights will begin to rise as high pressure starts to build into the area. Looks like this pattern will result in more record high temperatures by the middle of next week that will last into the following weekend.

For Mammoth Lakes that would mean highs into at least the mid 80s with Bishop in the 105+ range.  As of right now there no chance of any thunder storms through next weekend.

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 Schlaepfer – Mammoth WeatherGuy – The Powder Forecast – Posted Tuesday and Fridays at 5 PM November into Mid May. These forecasts are now responsible for many people getting multiple powder days on Mammoth Mountain over the years.  

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.”.
