A cold front has stalled over the Central Sierra north of Mammoth this Am. Some light precip is occurring along the crest and near the front according RAMSIS. The showery weather will dissipate through out the day and precip will then just be focused along the highest terrain in the moist onshore flow. 700mb winds are between 15 and 30 knots and so upper crest winds will be between 30mph and 60 mph today.
The strong west to east upper jet of about 170 knotts along 40 north moves onshore Tuesday morning once again favoring Northern Ca and will bring mainly some light orographically induced precip to the Mammoth Sierra
The system is currently moving through north of the big island of Hawaii taking the same track that the one that moved through Northern Ca yesterday. It is a little more moist and should be a better precip producer for north Central Ca northward. .
By Wednesday, the upper jet weakens and drops toward the Central Sierra bringing windier weather for Mammoth and a chance of Snowfall with lower snow levels and cooler temperatures. At the moment 1st guess would be 4 to 6 over Mammoth Mt. by Late Tuesday night. The system is warmer then yesterdays and so it might be rain/snow mix in town for a while before turning to snow Tuesday night. Update Tomorrow.
A larger storm is still expected for the Central and Southern Sierra after Thursday. This will be a colder storm.
