AccuWeather Forecast: Cold air returns overnight, Frost Advisory for hills, valleys

Takeaway of the Day

This Martin Luther King Jr. Day got off to a sunny, cold, and gusty start. It remains sunny and windy this afternoon, but the chill in the air has been replaced by a fairly mild range of temperatures -- mainly in the low to mid 60s.

Meanwhile, a Wind Advisory remains in effect for the North Bay interior mountains and the East Bay hills until 1 a.m. tomorrow; and a Beach Hazards statement is in effect until 7 p.m. this evening.

We can also expect a return of cold air overnight, as a Frost Advisory will be in effect from 1 a.m. to 9 a.m. tomorrow for the North Bay interior valleys, East Bay interior valleys, Santa Clara valley, and eastern Santa Clara hills.

The Look Ahead

Tomorrow will begin with bright skies but cold and frosty, as a Frost Advisory will be in effect until 9 a.m. for the areas listed above. However, the remainder of the week will bring much milder weather -- light winds, sunny skies, and high temperatures in the mid to upper 60s near the bay and inland.

But don't get too comfortable with the late week warmth, as a sharp cooldown will occur this coming weekend.
