3 Storms, 1 Week

Winter continues to provide for the Sierra as three more storms will impact the region over the next week. The first two storms are back to back beginning this evening with a slight break late tomorrow before picking up again into Wednesday. The second storm won't be as cold and will have a better moisture connection, which means snow levels will be a problem for powder hounds. However, most of the models are in good agreement that 2'+ of new snow will fall across the mid to high elevations of the Sierra by Wednesday morning.

1st and 2nd Storms
Base (~6000') - Mid Mountain (7500'): 1-2' of snow 
Above Mid Mountain (7500'+): 2-4' of snow; highest elevations could see upwards of 5' of snow


These look like great snow totals, but there will be some rain on snow especially mid-mountain elevations and below on Tuesday into Wednesday. This means the snow that falls late Monday into Wednesday will be wetter and warmer aka Sierra Cement due to the strong moisture connection from the Pacific (below) and the lack of a strong, deep trough accompanying it. This might suppress overall snow totals and also increase avalanche concerns through the week.

There is another storm forecast for Thursday into Friday, which looks to be colder than the middle storm, but it's a bit premature to start forecasting snow amounts and timing right now (although it looks good!). The good news is the record setting and epic current winter continues, so go out and enjoy it this week!
