Rain begins, chances will last through the day and into Friday

Good morning and happy Thursday Central Coast!
Here is a discussion of the state of the storm system as of 9:30am Thursday.

As the storm continues to move through the region rain continues to be possible into Friday morning.

Temperature wise we will stay a bit cooler than in the past few days as the rain cools us down a bit.

The rain will start in the far North West portion of San Luis Obispo county. As the cold front pushes through rain will also move through the region. All communities have chances for rain lasting into the early morning hours Friday.
Timing the system out here is what we are looking at.
Early morning the first few areas of rain will pop up in northern San Luis Obispo county. As the morning goes on the system will spread out and bring the western beaches and coastal valleys light rain. The first "wave" of the system will reach the Santa Barbara County southcoast by mid morning. After the rain moves through in the morning the much cooler and moist air will be primed for a second portion of the storm that will bring scattered showers, some strong enough to produce thunder in the evening hours. Rain chances will continue overnight into Friday morning before clearing out leaving Friday much cooler and gustier than previous days.

As far as rain totals go most locations will see totals spanning from 0.1" all the way to 0.5". The higher totals will mostly be localized to spots that see some of the stronger scattered evening storms.
Some locations in the Santa Lucia mountains in northern San Luis Obispo county could see much more rain up to one inch possible. Think locations like Rocky Butte for those totals.
Once the storms clear Friday winds will also turn and start some quick warming. Saturday and Sunday will bring above normal temperatures. Skies will remain clear with warm conditions through the week.
Even though you might not want to head to the beaches today we will warm up quickly into the weekend. That being said there is a high surf advisory in effect through Saturday night. Crests up to 10 ft are possible.
