Nice little system Friday with brought a few inches of snow to the town and up to 5 inches on Mammoth Mt reported. The remains of the upper low is now headed for San Diego at the moment and is expected to bring some pretty heavy showers later today.  As the upper system heads east tomorrow, a dryer NW flow will develop and cloudiness will diminish. More sunshine is expected Sunday into Monday. 500mb heights will rise early next week and so with temps.  Expect fair/dry weather Monday through Wednesday with highs in the 45 to 50 degree range.

As has been advertised the past week here at Mammothweather….the MJO will be moving into a more favorable position by next weekend. Highlighted by the GWO, the GSDM is forecasting Stage 1 by next weekend. The global relative AAM anomaly becomes negative as eastern upper level wind anomalies that extend from the Eastern Hemisphere tropics to the Western Hemisphere mid-latitudes. This results in a retracted pacific ocean jet stream. This is like mother nature taking her foot off the gas peddle where then the upper jet then retracts. Negitive frictional torque>Negative Mountain Torque then eventually northern momentum transport across 35north shown by the GWO.

A full latitude upper Trof is expectred to develop by the 17th/18th over the West Coast according to both ECMWF and the GFS. Considering the support of the GSDM and MJO…..the Dweebs regard this as a high confidence outlook even a full week away……  Additionally, the PNA is now forcasted to become negitive. Western Trof/Eastern Ridge….La Nina Style……Winter is setting in……….
