...Unseasonably cold storm system will bring threat of showers
and thunderstorms to southwest California Thursday into Friday...
A cold...winter-like storm system will dive southward into
California tonight through Friday. A slight chance of showers will
develop across southwest California late tonight into Thursday
morning. As the main low pressure system draws closer to the
region...there will be an increased threat of showers from
Thursday afternoon through Friday evening. During this
time...there will also be a slight chance of thunderstorms capable
of producing brief heavy downpours and small hail. These
thunderstorms may impact the rush hour commutes from Thursday
evening through Friday evening. In addition...conditions will be
favorable for isolated waterspouts across the coastal waters.
Another potential impact from this storm system will be low snow
levels. Snow levels could fall to around 5000 feet late Thursday
through Friday...and possibly lower in heavier convective showers.
A few inches of snow will be possible at resort levels...which may
require the issuance of a Winter Weather Advisory as we draw
closer to the event. In addition...gusty southwest to west winds
up to 45 mph will likely accompany this storm in Antelope Valley
and possibly the Los Angeles County mountains.
Rainfall amounts with this system will be quite variable due to
the showery nature of the expected precipitation. Isolated
rainfall rates up to one half inch per hour will be possible with
thunderstorms. As a result...if a thunderstorm were to move over a
recent burn area...there is the possibility of minor mud and
Residents of southwest California should monitor the latest
National Weather Service products for this developing weather
situation. Anyone planning to travel to the local mountains should
prepare for the possibility of snow showers and gusty winds.
