Mammoth Weather Update for Monday, July 19th, 2021 @ 9:22 AM
Synopsis: This week starts with what looks like to be a good day for thunderstorms and heavy rain showers. Rainfall amounts under storms that do form could be in the .10 to .20 QPF range.
Starting Tuesday we dry out with just a few clouds around. Expect average highs for July in the high country, lower elevations will remain a bit above average.
The usual afternoon Summer winds will be back starting Tuesday. Winds will be from the SW at 10-15 MPH with gusts over the higher elevations 25-35 MPH during the PM hours.
As far as smoke and haze in the area, I would expect just light amounts at times until further notice.
By next weekend there will be isolated thunderstorms returning that will last into the following week.
Looking out over the next 16 days I am not seeing any excessive heat waves, temperatures do look to warm up in about a week and then quickly return to just above average highs out to 16 days.

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.”.
