SLO County weather forecast for the week of June 21: Fog at the coast, hot inland
Last week, it was windy with mostly clear skies and well above normal temperatures.
This week, it will be the opposite, with gentle winds, marine low clouds with night and morning fog and drizzle and below typical temperatures.
High pressure will begin to build into the Central Coast Sunday and produce fresh to strong (19 to 31 mph) afternoon northwesterly winds along the coastline, which will produce clearing there during the afternoon. Inland valley temperatures will increase to the mid-90s on Sunday.
A weak low-pressure system will move into the Central Coast on Monday. This system will produce an extended period of gentle to moderate (8 to 18 mph) southerly winds, a persistent marine layer with night and morning fog, mist and seasonal temperatures.
Overall, a classic summertime weather pattern will continue through next week with widespread 90-degree temperatures across the inland areas and 70s in the coastal valleys. High temperatures along the beaches will remain in the 60s.
