The tendency for big storms
to hit on the off-days is broken today as a
major, slow-moving Pacific storm will move onshore to California tonight into
tomorrow. With unseasonably cool temperatures, precipitation will fall as snow and
fall heavily tonight through tomorrow afternoon due to the strength of the
storm, moisture influx from the Pacific, and upslope. Based on past snowstorms,
I do not think undercatch will be much of an issue, though models might be
overestimating precipitation a bit. Thick clouds will negate the diurnal
temperature cycle, and temperatures will stay near freezing while the heavy
snow falls since any slightly to modest above freezing temperature will be
cooled to the freezing point through first evaporation and then melting of falling
snowflakes. Temperatures will rise somewhat as snow stops late tomorrow
afternoon but it remains cloudy. Winds will be out of the south or southeast. Though
these winds are rarely strong at Mt. Shasta, they likely will be noticeable
this time due to the sheer strength of the winds aloft.
