Mammoth Weather Forecast and Synopsis for Friday, August 6th, 2021 @ 11:10 AM

Current Conditions: Currently there is a temperature up the top of 54 with an ENE wind @ 5 gusting to 8 MPH. Mammoth Lakes @ 71, Mammoth Airport @ 73 and Bishop @ 84. 

Air Quality is good in Mammoth with moderate to unhealthy in the Bishop Area. Looking at the Webcams and Satellite images smoke is, unfortunately, moving our way.  

Recap for the Past day: Yesterday up at the top of Mammoth Mountain we had a high of 57, winds peaked out at 67 MPH out of the WSW.  This morning’s low got down to 43.

Down at Main Lodge, the high was 65 with a peak wind gust of 22 out of the  WSW, this morning’s low was 47.

For Mammoth Lakes, yesterday there was a high of 74 with a low of 55 this morning, Bishop got up to 103 with a low of 57.  

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

Weather Synopsis: The weather ended up trending seasonal temperature-wise over the last couple of days. Winds did pick up with gusts to 60 MPH over the higher elevations.

Upper levels winds have changed and with the explosion of the Dixie fire 200 miles to our north, we are getting some smoke and haze. The line of smoke is clearly visible on the satellite images down the page.

The good news is we do not expect heavy smoke in the area and most of this smoke should clear out by Sunday.

High Pressure will start to build into the area over the weekend leading to above-average highs all next week. Dry conditions will prevail until the latter half of next week. At that point, there could be a return of a weak monsoon flow.

Temperatures: Highs over the next week will be in the mid-70s on Mammoth Mountain and up in the Mammoth Lakes Basin at the 9000-foot level. Mammoth Lakes will be in the upper 70s to low 80s with Bishop into the upper 90s. 

Smoke and Haze: Checking area gauges the worst of the air quality is down along the White Mountains to the east of Bishop. It looks like the smoke will make it to the Mammoth area sometime later today.

This smokey mess looks to be with us for about 36-48 hours before it starts to dissipate and move to our east. Forecasting smoke can be tough so don’t be surprised if it’s around all weekend.

Here are the links to the local NWS Forecasts 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.
