One again snowfall amounts are expected in the 6 to 12 inch range with this next chilly Gulf of AK storm. The Maverick in this type of pattern is how and where the upper low spins up at 700MB and thus where the area of deformation sets up and how long it remains over a particular area and if that area favors Southern Mono County. That will  be the key to the higher amounts. At the least, we can expect a good 6 inches up on Mammoth Mt and if the area of surface convergence sets up near Southern Mono County or begins to the north of us and slides south, we could see the amount of a foot or better over the upper elevations. Snow fall amounts in the cold air will be at a higher than normal ratio to water, just like the last system.  However, not to the degree to call for a Platinum Powder Alert.  500MB temps are forecasted to be about -28C and 700MB temps about -10C, this will definitely bring snow to water ratios to possibly 11 or 12:1, but it is doubtful it would be cold enough in the Dendritic Growth zone for ratios equal to or >15:1…..  So light and dry powder yes, A blast to easily cut through, but not Eastern Sierra Platinum…..
