Areas affected...higher elevations of the southern Sierra

Concerning...Heavy snow=20

Valid 180020Z - 180215Z

SUMMARY...Heavy snow should continue over the southern Sierra
through 06Z, with 2-4 inch/hour rates possible over the next few
hours.

DISCUSSION...A mid-level impulse is expected to overspread much of
central CA over the next few hours, which should further increase
moisture advection and stronger localized forcing for ascent along
the windward side of the southern Sierra this evening. Multiple
instances of heavy snow have already been reported at the BAN, BIH,
and MMH ASOS sites over the past hour or so, and the expectation is
for heavy snow to persist across the southern Sierra through at
least 06Z. The heaviest snowfall rates (perhaps in the 2-4 inch/hour
range) appear most likely from now into the 04Z time frame, in
agreement with HREF ensemble probabilities.
