Short lived convective cells (cumulonimbus clouds)
moved over the Templeton area yesterday afternoon
and produced areas of hail.
A pattern of moderate to fresh (13 to 24 mph) Santa
Lucia (northeasterly) winds developing during the
night & morning hours, shifting out of the northwest
and increasing the strong to gale-force (25 to 38 mph)
levels during the afternoon hours will continue
This condition will produce dry conditions under

The upper-level winds will continue to push a cold
air mass from the north into the Central Coast.
Consequently, temperatures will drop to well below
seasonal averages. Low temperatures in the North
County and wind sheltered valleys will drop to the
mid to high 20s, while closer to the coast, low
temperatures will lower to the mid 30s on Friday
into Saturday. Afternoon highs will range between
the mid 50s to low 60s.
Over the last 18 hours the numerical model runs have
significantly reduce the strength of Sunday's weather
system. A 1,002 millibar surface low combined with an
upper-level though will produce gentle to moderate
(8 to 18 mph) southerly winds, mostly cloudy skies and
rain. Snow levels will lower to the 2,500 and 3,000
foot range with light accumulations on the higher
peaks of the Central Coast.
A few lingering rain showers are expected Monday,
then dry and much warmer weather is forecast during
the first week of March which may reward us with a
spectacular bloom of wildflowers. We have reached the
amount of rainfall needed to germinate many of the
