Forecast for Sunday evening September 18

Showers appear in northern portions of San Luis Obispo County late on our last Sunday of summer 2022. As expected, much of the energy will continue to remain in our northern regions. Expect the showers to gradually push south through Monday morning. Rainfall totals will vary widely in parts of San Luis Obispo County, hopefully picking up and inches or more. Unfortunately, the further south you go the numbers drop dramatically, with the South Coast and Ventura County possibly seeing very little or even nothing. Temperatures on Monday will be mostly in the 60s and 70s as a southerly flow keeps us milder than cool despite the storm clouds.

Going forward, our start to the season and an unusually strong storm will continue to sweep through the region as we head into the new work week. Our northern areas of Santa Barbara and San Luis Obispo counties will likely see decent showers on Monday. In fact, one of our forecast models shuts down and drops even more rain with totals that can exceed an inch! This is great news for drought issues and will also help firefighting efforts in Northern California. Chances of showers will persist through Tuesday and again the best chance will be further north as you go with many areas south of Point Conception seeing very little or nothing at all. However, one of our forecast models sees the system dropping a bit further south and if that happens the south coast could see a better chance of measurable rainfall. Mid-week the skies will clear and we might even see a decent warming trend as we look into the first weekend of fall!
