SLO County weather forecast for the week of Feb. 11

San Luis Obispo - The TribuneFebruary 10, 2013 

Here is this week’s weather forecast by PG&E meteorologist John Lindsey, who is based in San Luis Obispo:

A 1,031-millibar eastern Pacific high will remain anchored off the California coast. This area of high pressure will produce an omega block that will keep the Central Coast dry for an extended period.

The jet stream is moving southward from British Columbia toward California and producing below-normal seasonal temperatures. The North County will drop to the mid- to high 20s during the morning hours through Tuesday.

The omega block will slide eastward over the Western U.S. on Wednesday and will direct colder air toward Nevada and Utah. This condition will allow the high-pressure ridge to strengthen and produce night and morning northeasterly winds, resulting in warmer temperatures and generally spectacular weather for the middle part of February.

Fair weather will continue through the Presidents Day holiday weekend. The next chance for rain showers appears to be Feb. 21.

Today’s 6- to 8-foot northwesterly (300-degree deep-water) swell with a 16- to 20-second period will remain at this height, but with a 15- to 17-second period on Tuesday morning.
