Cooler, dry, and breezy; despite the cool down fire danger will remain a concern into next week.

Humidity levels are much lower this week, in comparison to last week. Relative humidity levels are down to the single digits in the deserts, and teens in our mountains. Lower humidity does make it more comfortable, but beyond comfort fire danger will become a higher concern.

A storm to our north will trigger gusty winds in the eastern part of the county ranging from 20 to 35mph. The winds will be onshore through Sunday but shifting to the east on Monday and Tuesday of next week. Offshore winds are another name we use for Santa Ana winds.

As fire danger remains high, here are some tips to help you stay weather ready. Remember to ensure you have defensible space around your home, go over your evacuation plan with your family, and check your emergency go kit is stocked.

The marine layer will spread inland each morning clearing out to sunny skies, most areas by mid to late morning. Patchy fog will be possible during the morning commute.

Temperatures start to go back up for the first day of fall on Wednesday, with the Autumnal Equinox happening at 12:21pm.

Friday's Highs:
Coast: 69-74°
Inland: 75-84°
Mountains: 78-89°
Deserts: 98-103°
