Eastern Sierra Weather Synopsis:

A very strong ridge of high pressure will be the story over the next week. The higher elevations will see very warm daytime temperatures with dangerously hot conditions below 7000 feet. 

Temperatures look to be at or near record levels Friday into Monday. A minimal increase in moisture will bring isolated thunderstorm (20% chance) activity to parts of the higher elevations of the Sierra today into Sunday.

By next Wednesday highs look to come down about 4-6 degrees from the peak of this high-pressure ridge. 

Lows at night will be warm until well past the midnight hour. If you’re coming up to the area make sure to bring a fan or two or you’re going to be too warm at night for a good sleep.

For this traveling to the area over the next week. Please know that in the Owens Valley there will be an extended period of heat expected.

Areas south of Bishop will be near 110 mid-day. Make sure your vehicle is ready for those conditions.

NWS ALERT BISHOP: EXCESSIVE HEAT WATCH IN EFFECT FROM WEDNESDAY MORNING THROUGH MONDAY EVENING…FOR THE ENTIRE OWENS VALLEY. TRAVELERS BE PREPARED.

Who Are We?

2019 12 28 1657Steve 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.

WG 102 1Ted 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.”.
