Snow has arrived and will remain entrenched through the night. Cyclogenisis has begun and 2-4″ per hour snowfall rates will be common inland ( 15 miles inland from the coast.) and 3″ per hour rates at the coast though inefficient accumulation will lead to lesser totals. Thunder will be likely at the peak intensification time ( 10pm-2am)
Snow amounts stay the same.

New radar updates filtering in now and the situation is clear. Definite spin with the original low and secondary low forming as well. The low has stalled and so precip will hold off until after dark. Second low will intensify as it moves NE and bring more stable accumulations with dropping temps. Snow will end near dawn Saturday in most areas excluding the mountains where upslope snow showers will continue to crank Saturday
