Mammoth Lakes and Eastern Sierra Weather for Thursday, September 2nd, 2021 @ 10:57 AM

Good morning, there has been a nice cool down from Mammoth to Bishop over the last 24 hours.

As the low that has helped to bring us the cooler weather and clear skies moves to the east temperatures will slowly rise 4-6 degrees by Sunday into Monday.

The ridge of high pressure that will bring the warming will quickly move off the east by the middle of next week and temperatures will return back to average for this time of year.

Some of the models due have some precipitation from t storm next week, but as of now that’s highly suspect. Let’s pray all thunder storms stay was away, the last thing we need is lighting and new fire starts right now.

Smoke and Haze Update: Looks like the smoke haze will move back into the area starting on Friday. The NWS service thinks our air quality will not be great for the next week. (The HRRR smoke forecast can be really good but if any new fires happen or there are major flare-ups on the current fires, that forecast could change.)

Here is the link you can use to monitor the air quality in the Eastern Sierra. When the pointer is in the green or yellow range you’re good to go out and play. When the pointer hits orange and red I would avoid being outside for extended periods of time.

Also to note, only the N95 masks work to help prevent the haze and smoke particles from entering your lungs and bloodstream. The blue masks everyone is wearing are worthless against wildfire particles.

Temperatures for Friday and Saturday : Highs will be in the upper-60s on Mammoth Mountain and up in the Mammoth Lakes Basin at the 9000-foot level. Mammoth Lakes will be in the mid 70s with Bishop into the low 90s

Night-time lows will be in the mid to upper 40s for the high country and into the mid-to-upper 50s for Bishop and Round Valley.

Winds: Expect southwest winds in the 5-10 MPH range in the lower elevations with upper elevations seeing gusts in the 10-20+ MPH range at times.

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 towards the early Fall season we can expect to start to see insider sliders show up by late September into early October. Many a year there will also be the first dusting of snow later in the month of September.

I am watching daily and will post when we have something to talk about. I do promises not to jump on the hype train here with false expectations.

The next long range charts for the ECMWF should be out in the next 24-48 hours and I will post them up as soon as I have access.

For the upcoming Winter, more then half of the extended models have us in a neutral ENSO state, with some showing a weak La Nina. As of now, I expect the chances of an average snowfall winter are much greater than a 3rd year of exponential drought.
