SLO County weather for week of Aug. 23 — Cooler temperatures and hazy skies

Unlike the record-breaking temperatures of last week, this week’s temperatures will cool to typical seasonal levels, but hazy/smoky skies and periods of subtropical moisture will continue to stream overhead.

Moisture from the remnants of Tropical Storm Genevieve will continue to move into the Central Coast on Sunday into Monday morning bringing increasing high-level clouds with virga and the chance of scattered rain showers and isolated thunderstorms. The best chance of thunderstorms will occur over the southern Sierra Nevada. Note: Any storms that develop will have potential for frequent lightning and gusty winds.

Sunday’s high temperatures will range from the low 90s in the inland valleys (Paso Robles) and low 80s in the coastal valleys (San Luis Obispo). The beaches will remain in the 60s. Little day to day change in terms of temperatures is expected through Monday.

The marine layer is forecast to return along the coastline later Monday with areas of night and morning mist and fog in the coastal regions continuing through Friday.

High pressure around the Four Corners area is then expected to expand westward toward the West Coast, producing a gradual warming trend on Wednesday through Friday away from the coastline with the North County reaching the high 90s and the coastal valleys the low 80s.

Variable amounts of smoke from the wildfires should continue to reside over the state over the course of the week but will not be nearly as bad as last weeks. The long-range models indicate little change in the overall weather pattern through next week, with seasonable to slightly above average temperatures continuing into September with typical fair and dry late summer weather.
