Christmas Day promises to be sunny and warm as an upper-level, low-pressure system continues to hang around the Central Coast.

The National Weather Service said Sunday’s daytime temperatures are expected to be in the mid-70s on Santa Barbara County’s South Coast, with west southwest winds of about 5 mph.

Overnight lows on the South Coast are forecast in the mid-40s, but a frost advisory remains in effect for the Santa Ynez Valley and inland canyons.

The rest of the week — or the year, if you prefer — will see similar conditions, with sunny skies during the days and temperatures in the upper 60s and low 70s.
