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.
