Mammoth Mt continues to make snow and are expanding the runs for skiing….  It is very cold and dry…..excellent snow making conditions!

No surprises this morning. Although not as robust as the last system…..Another reinforcing shot of cold air has invaded the high country bringing light winds to the Town of Mammoth, moderate winds to the upper elevations. The crest will be windy today.  It is very cold with a low of 7 here at the village and 13 degrees as of 8:30Am. The pattern out over the eastern pacific is highlighted by a highly amplified upper ridge at 140W and the down stream trof over the Central Rockies. Several shots of cold Western Canadian air will continue into Great Basin and Rockies early next week. The +PNA continues to defy the SSTA’s/-PDO, as it is quite positive with both the NAO and AO Positive as well.  MJO is slowly progressing east into the Maritime Continent. It is in phase 4 and so far the only changes that are notable is that some “weak” under cutting is now possible during week 2. However, it’s effects would be well south of Central Ca to do any good and would more likely effect more of the southern tier states during week 2.  There is always the possibility that the MJO might spawn a strong Western Pac tropical storm that would re-curve north and constructively phase with the westerlies. Over the next several days, the MJO will be in an area where that could happen.

Over all….the Western Hemispheric Pattern reminds the Dweebs of more like a weak El Nino or Weak La Nina rather than the current Light to Moderate La Nina. So….no matter what happens through the end of this year……The Dweebs feel that Winter will be back!
