Rain, humidity hit SLO County as ‘monsoonal moisture’ spreads over California

Much of San Luis Obispo County woke up to a humid, drizzly day on Sunday thanks to “monsoonal moisture” spreading across California.

According to the National Weather Service, “a hot and muggy week” is expected as an upper level high front brings tropical moisture from Mexico.

This translates to warm, humid days — and yes, some chance of thunderstorms.

“Monsoonal moisture moving into the area will add to the discomfort, bringing shower and thunderstorm potential each day, highest in the mountains,” the weather service said.

During this, light showers are possible, “especially for San Luis Obispo and Santa Barbara counties,” the weather service said.

The service warned the possibility of lightning was strongest in the interior sections of Los Angeles, Ventura, and Santa Barbara counties on Sunday afternoon, though ”an isolated lightning strike cannot be completely ruled out closer to the coast.”

This comes at the same time much of the Central Coast is still under an ongoing heat advisory warning of temperatures near 100 degrees and an expected extreme heat watch starting Tuesday.

The chance of actual showers will reduce as the week goes on, but the humidity will remain high, the agency said.
