Little in the way of change in sensable weather the next few days…. Highs in Mammoth will be in the low 70s with lows in the mid 30s. Expect very light NE breezes in the morning but not enough to help much in the poor air quality as westerly flow will resume later in the day Monday and Tuesday.  A change in the pattern is expected going into the following weekend with a fairly dry cold front expected Saturday afternoon. The front will bring both wind and cooling of between 20 to 25 degrees. Hard freeze conditions are expected next Sunday AM and daytime highs may not get out of the 30s on Sunday.  With this Great Basin Slider, will come the possibility of some high elevation snow showers and possible rain showers. The precip is classically behind the front late afternoon Saturday and night as with most Great Basin sliders. Even through we may get some precip, this is classically a dry pattern for the Central Sierra.

La Nina…..This is the tropical base state currently over the tropical pacific.  Trades are very strong north of the equator and are pushing more and more warm water to the western pacific.  The Walker Pump will continue to shift westward.  Some models suggest that this La Nina will be a strong one. And……….Although the “Bias” for Mammoth with a La Nina Winter is drier than normal. There are never any guarantees!  Overall best guess is a little drier than normal winter with some “very interesting storms!” 🙂 La Nina is expected to peak the end of December….


In the Meantime, after next weekends cool down, it is expected to warm up again later in the following week… But it will be very diffacult to hit 70 degrees again the last week of October!

Time to let it go!!

The Dweebs will begin to update more often in the near future….


If you can smell smoke and see ash, that is an indication that you should be treating air quality conditions

Limit your outdoor activities, especially children and people with chronic heart and lung diseases.
  1. Remain inside air conditioned buildings. Note: If you do not have an air conditioner, staying inside with the windows closed may be dangerous in extremely hot weather. In these cases, seek alternative shelter.
  2. If you have asthma or other lung diseases, make sure you follow your doctor’s instructions about taking your medicines and following your asthma management plan. Call your doctor if your symptoms worsen.
  3. If you are an older adult, have children, or if you have heart or lung diseases, talk with your doctor about whether you should leave the area.

Please note: Smoke is a mixture of gases and fine (microscopic) particles that can cause health problems. The PM 2.5 monitors are designed to detect these fine particles. Ash pieces, however, are much larger in size and will not be detected. If an area is covered in ash, air quality should be considered.
