Focus now  will be the big rain maker getting set up for Southern CA.  There is a rich source tropical plume just north of the dateline associated with the low frequency base state that has connection east, then North Eastward to Northern Baja and Southern CA. next week.   A short wave, in back of the wave that will bring Mammoth some light snowfall Saturday, is currently moving ESE through the G of AK and will drop south and spin up over the next several days as it makes its way toward Southern CA early next week. The Closed nature of the system makes it more difficult to time as compared to the open wave across the pacific.  Our friend the EC ensembles puts it through Southern CA next Wednesday.  As a result, the best forcing will be Monday and Tuesday as a rich tap of tropical moisture combines with both dynamic lift as well as Orographics.  The coastal sections of So-Cal seem to have the best combo, especially areas like Malibu, east and south. This should be a good rain maker from Southern CA east…..

Mammoth Mt;


Preliminary est….2 to 5 inches over the crest Saturday. and another 12 to 15 inches Monday-Wednesday.  Dry Thursday.  Highs today fFriday in the low 50s cooling to the 40s on Saturday and low 40s Sunday. Expect 40s for high in town early next week.  This is not considered a cold storm. Snow level will rise to around 6000-6500 feet. It will be breezy this afternoon through Saturday night. Windy over the crest….


Currently, Mammoth Lakes is under high pressure ridging, We can expect above normal high temperatures through Friday with low to mid 50s. There after, a “long wave trof” will set up over the Eastern Pacific allowing slow moving closed lows to creep on shore. The period Monday through Wednesday next week could bring fresh snowfall to Mammoth Mt. Although the exact trajectory of this system is Unknown at this time. The effects of the next lifting mechanism to boot it in will determine who gets the lion share.  There is the potential of moderate snowfall on Mammoth Mt next week. Moderate  (6-18 inches)  The long range outlooks from both the CFC and CPC show the potential for a wetter March, especially for Southern CA. The CPC has indicated that an area of enhanced convection over the tropics near the Dateline may supply atmospheric river moisture in the weeks to come for Southern CA.
