SLO County weather forecast for the week of Dec. 30

Special to The TribuneDecember 29, 2013 

Here is this week’s weather forecast by PG&E meteorologist John Lindsey.

Weather report

A 1,024-millibar Eastern Pacific High firmly anchored off the California coastline will keep the storm track far to the north. A 1,034-millibar area of high pressure over the Great Basin will continue to produce night and morning Santa Lucia (northeasterly) winds. These winds will give mostly clear skies with low relative humidity levels.

Temperatures today will range from the low 70s in the North County and beaches to the low 80s in the coastal valleys. Tonight will be clear with overnight minimums mostly in the 30s and 40s, with the coldest spots in the North County in the upper 20s.

Tuesday is forecast to be slightly cooler as high clouds will start to stream over the Central Coast. These clouds may produce some beautiful sunrises and sunsets. The partly cloudy weather will continue on New Year’s Day with little change in temperatures.

Increasing northwesterly (onshore) winds will produce a few areas of marine low clouds along the beaches and slightly cooler temperatures on Thursday into Friday.

A weak area of low pressure is then expected to move through San Luis Obispo County this weekend with more seasonal temperatures but no rain. Most of the longer-range models are hinting that precipitation chances will increase toward the middle or end of next week, although there is still quite a bit of uncertainty regarding the potential pattern change.

Today’s surf report

Today’s 4- to 6-foot northwesterly (295-degree, deep-water) swell (with an 8- to 16-second period) will continue at this height and period through Wednesday morning.

Increasing northwesterly winds along the California coastline will generate a 3- to 5-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 14-second period) Wednesday afternoon through Friday.

A 3- to 5-foot northwesterly (295-degree, deep-water) swell (with an 8- to 13-second period) will develop along San Luis Obispo County’s coastline this weekend.   

Seawater temperatures

Seawater temperatures will range between 55 and 57 degrees through Sunday.
