   Areas affected...portions of the higher terrain over the Sierra in
   central California

   Concerning...Heavy snow 

   Valid 042229Z - 050230Z

   SUMMARY...Heavy snow should continue over the higher terrain of the
   Sierra in central California for at least the next 4-6 hours. In the
   next couple of hours, brief bouts of up to 3 inch/hour rates are
   possible.

   DISCUSSION...Heavy snow (2 inch/hr rates) should continue across the
   higher terrain of the Sierra over the next several hours as a
   mid-level trough and associated surface cyclone meanders along the
   CA coastline. 22Z mesoanalysis depicts a 500 mb jet streak
   overspreading CA (including the northern Sierra), with a pronounced
   700 mb impulse beginning to approach the higher terrain along with
   stronger low-level warm-air advection. The net result should be
   continued deepening and moistening of the dendritic growth zone,
   which should also experience enhanced deep-layer ascent. The
   increase in ascent within the dendritic growth zone may support an
   increased snowfall rate of up to 3 inch/hr in the higher terrain of
   the Sierra, beginning now and continuing through at least 01Z.
