Santa Ana winds peaked this morning between 2 and 5am with gusts averaging between 30 to 60mph. The winds will die down this afternoon, shifting to onshore winds on Friday.

The sky will stay clear tonight, with mostly sunny skies Friday. Temperatures will start to cool down, with greater cooling into early next week. The winds out of the west will become gusty over the mountains averaging 15 to 30 mph on Friday and Saturday.

The weekend outlook brings low clouds, and cooler temperatures in the upper 60s for the coast, and low 70s inland, making it a lot more comfortable for trick-or-treaters this Halloween.

The marine layer will deepen with clouds stretching into our valleys Sunday into Monday morning, leading to low visibility in some areas. Monday will trend 5 to 10 degrees below average, but we will see a gradual warm up Tuesday.

Warmer conditions will weaken the marine layer, with sunny skies for the middle of the week. The first week of November looks relatively quiet, with comfortable temperatures, and plenty of sunshine.

Thursday's Highs:
Coast: 73-78
Inland: 83-88
Mountains: 75-81
Deserts: 86-91
