SLO County weather forecast for the week of June 6: Clear skies and warm temperatures

Last week saw warm inland temperatures under sunny skies, while the coastline mainly remained overcast throughout the day with night and morning mist and drizzle. This week will start cool and dreary before gale-force northwesterly winds develop later Tuesday and continue through Saturday, producing clearing skies and warmer temperatures.

A 1,009 millibar low-pressure system and associated cold front will increase clouds with pockets of mist and drizzle and cooler weather on Sunday into Monday. Late morning and afternoon clearing are expected in the inland and coastal valleys; however, high-level clouds will continue to stream over the Central Coast.

As a result, the beaches will remain overcast throughout the day. Over this period, Paso Robles is only expected to reach the mid-70s, while San Luis Obispo the mid-60s. The beaches will remain in the 50s.

Gentle to moderate (8 to 18 mph) southerly winds are forecast on Sunday into Monday morning, shifting out of the northwest and increasing to fresh to strong (19 to 31 mph) levels on Monday afternoon and night.

In this cold front’s wake, strong to gale-force (25 to 38 mph) afternoon northwesterly winds along the coastline and clearing skies with warmer temperatures are forecast throughout the Central Coast on Tuesday through Saturday.

The long-range models hint at another low-pressure system bringing widespread drizzle on Sunday or early the following week. Still, details remain uncertain, and updates will be given as the forecast evolves in the coming days.
