Thursday AM:
Not much change in the weekend outlook with breezy weather developing for Friday night into Saturday over the upper elevations. Little temperature change this weekend with highs in the mid 60s. Forecast models and ensembles of both EC and GFS are leaning toward cooler weather the first half of next week with periods of windy weather toward Tuesday and Wednesday. WX maps show cool upper Trof setting up over the Great Basin and a return to cooler than normal temperatures…

At the moment the pattern change is dry….

Weather over the Eastern CA this week will be pretty benign with Mammoth between two different air masses. One is the storm that came through last week that has become a static feature over the Great Basin weather wise. The low pressure Trof over the Great Basin and the upper ridge off shore are providing a north-south gradient over Eastern CA. There appears to be a short wave that will drop into the Great Basin weakness and provide a bit more gradient tonight and Tuesday some north winds may pick up a bit over the Owens Valley. By Tuesday, the Trof splits with one portion ejecting NE toward the upper mid west and the remains of the old Trof hanging back to gradually weaken. The Upper Ridge off shore does come in over the weekend with the warmest temperatures expected. We may see highs in Mammoth approaching 70 by Saturday. The cold temps at night will moderate as well with lows in the 20s rising to the mid to upper 30s this week. It is a great time to be in the back country, however, we did pick up as much as 10 inches of snow above 10,000 feet last week.

There is little certainty this morning in any storminess next week. I would say that the likelihood of any significant precip at this time is pretty low. There is a slight chance of some showers through during the week 2 period. It looks like there will be a period of cooler weather along with breezy conditions as there is a belt of westerlies expected to move into the Pacific NW next week.
