Above normal temperatures along with fast moving rivers and creeks will continues through Mid Week while another cool late spring Trof approaches.  Daytime highs, now in the mid 70s in Mammoth and over night lows in the 40s will give way to highs near 60 by Saturday with over night lows in the upper 20s and low 30s by weeks end.  This is all due to a vigorous Trof that is dropping SE out of the Gulf of AK with its target upon extreme Northern CA Northward. Another round of heavy rainfall is expected along coastal areas of Oregon State.  For much of Central and Northern CA,  it will mean mainly Wind and Cooling with a chance of showers.  High temperature’s will begin to recover by the following Tuesday and the weather for the 50th Mammoth Motocross looks very nice with highs returning to the 70s.

Summer Weather;

It is the opinion of Mammoth Weather, that with the deep Solar Minimum approaching, summers will be increasingly cooler than the past 5 years with stronger more frequent afternoon Zephyr’s.  Normal to possibly below normal temperatures and less thunderstorm days are expected for the Central Sierra. Gulf of AK Trofing will remain stronger with migratory short wave incursions to the Northwest pacific coast creating more wind through the Mammoth Pass this summer, and possibly the summers following for the next 5 years.   The continental high may end up being more squashed east west affecting Southern CA more with summertime thunderstorms with periods of anomalous easterly flow remaining well south of the Central Sierra. Winters may tend to be wetter than normal along the central and northern west coast over all.
