pgeweather@pge.comJune 2, 2013 

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

Weather report

The gale force northwesterly winds that have dogged the San Luis Obispo County coastline for weeks have finally diminished as a weak trough of low pressure moves toward the Central Coast. These relentless winds produced clear and sunny conditions along the beaches. However, today and tomorrow’s gentle to moderate (8- to 18-mph) southwesterly winds will allow a deep marine layer with fog and drizzle to persist along our coastline for most of this day. Ironically, the northwesterly facing beaches of (Morro Bay, Los Osos and Montaña De Oro State Park) may escape the June gloom as the southerly winds blow down the Irish Hills and produce clearing at those locations.

Today’s temperatures will only reach the middle 70s in the North County and high 60s in the coastal valleys. Temperatures at the beaches will range from the low to mid-60s.

The marine clouds will continue to expand leading to a bit more cooling for Tuesday, which should be the coolest day this week, with not a lot of change expected Wednesday. Overall, expect a typical summer type pattern of low clouds and fog along the coast to sunny skies inland.

Changes start to occur on Thursday as a strong high pressure ridge is expected to build over California. Temperatures should go up across the North County with only a modest rise just away from the coast with further warming expected in all locations Friday as the ridge continues to strengthen over the Central Coast.
