A series of weather systems is bringing scattered rain showers, the risk of isolated downpours and thunderstorms, and the potential for snowfall in the higher elevations of the Santa Barbara and San Luis Obispo county mountains this weekend across the Central Coast region of California.

Why it matters

This active weather pattern will provide beneficial rainfall to the region after recent dry conditions, helping to boost the Sierra Nevada mountain snowpack. However, the unstable atmospheric conditions could also bring brief heavy downpours, gusty winds, and lightning, requiring residents to be prepared for variable weather impacts.

The details

The first of two upper-level disturbances is currently moving through the area, bringing scattered light rain showers and the risk of isolated downpours or thunderstorms. A second, more potent system is expected to arrive Saturday night into Sunday, with a focused 3-5 hour period of steady rain and possible thunderstorms across both counties. Rainfall amounts of 0.5 to 1 inch are forecast, with locally higher totals possible in the Santa Lucia and Santa Ynez mountain ranges. Snow levels will start around 7,000 feet on Sunday, dropping to 6,000 feet by Sunday afternoon, potentially bringing 1-6 inches of snow to elevations above 6,000 feet.

  • The first upper-level disturbance is moving through the area currently.
  • Scattered light rain showers and the risk of isolated downpours or thunderstorms will continue through Saturday afternoon.
  • The second, more potent system is expected to arrive Saturday night into Sunday morning.
  • A Winter Weather Advisory is in effect from 9 pm Saturday until 11 am Monday for elevations above 6,000 feet.
  • Drying and warming trends are expected to begin on Monday, with temperatures reaching near 70 degrees at the coast and mid-70s inland by midweek.

What they’re saying

“Atmospheric conditions will become notably unstable with CAPE values around 500 joules per kilogram - sufficient energy for convective activity, including brief heavy downpours, gusty winds, and lightning. There's even a small possibility of a waterspout given sufficient low-level wind shear.”

— Jim Castillo, Meteorologist

What’s next

Residents in the Central Coast region should monitor the weather forecasts and be prepared for the potential of heavy rain, thunderstorms, and snow in the higher elevations over the weekend.

The takeaway

This active weather pattern will bring much-needed rainfall to the Central Coast region, helping to boost the Sierra Nevada mountain snowpack, but the unstable atmospheric conditions could also lead to variable weather impacts, including brief heavy downpours, gusty winds, and lightning.
