Mammoth Weather Update for Wednesday, August 24th, at 8:53 AM

Current Conditions: Currently there is a temperature up top of 59 with a WSW wind @ 22 gusting to 22 MPH. Mammoth Lakes @ 71, Mammoth Airport @ 53 and Bishop @ 63. Air Quality is good with just a bit of haze in the area.

Recap from the past day: Yesterday up at the top of Mammoth Mountain we had a high of 62, winds peaked out at 42 MPH out of the WSW. This morning’s low got down to 52.

Down at Main Lodge, the high was 65 with a peak wind gust of 15 out of the SSW. For Mammoth Lakes, yesterday there was a high of 80 with a low of 58 this morning, Bishop got up to 104 with a low of 60.

There was no recorded precipitation in the area over the last 48 hours.

Weather Synopsis:

A trough off the northern California coast will be moving inland across N California later today into Thursday. The result will be dry and windy conditions with extreme fire weather possible. A Red Flag Warning is up for Thursday until 10 PM. As we move into Friday winds will back off and highs will start to come back up a bit.

Over the weekend highs will be a bit of average for this time of year and will be accompanied by a dry SW flow with the typical afternoon winds we see during the summer months.

There are no signs of any excessive heats waves or new thunderstorm outbreaks at this time.

Temperatures: Look for low 70s for Mammoth Mountain with the upper 70s to low 80s in Mammoth Lakes. Down in Bishop, highs will be near 100 today and cool off to the upper 90s over the weekend.

Smoke and Haze: We have been experiencing some haze at times. I have not smelled any smoke from Mammoth to Bishop in about a week now. AQI levels have remained in the good range and should stay that way until further notice.

Here are the links to NWS Forecast for Main Lodge & the Mammoth Lakes Basin, Mammoth Lakes, June Lake, Crowley Lake, and Bishop.

Extended Outlook: Looking out over the next 16 days I am still not seeing any excessive heat waves and no return of the Monsoon yet.

Looking out towards Fall and into the Winter months, it’s looking dry and warm to start. Models have moved from a neutral winter to forecasting a la Nina to set up again.

Kind of early to jump on how strong it could be. Mammoth and the central Sierra have done good with weak La Nina’s, not so bad with moderate ones but if it’s strong again expect a drier year.

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 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.
