Good morning, Central Coast!

There is a lot going on in your forecast so let's dive right in.

To kick off Wednesday morning there is significant fog across some of the western beaches and coastal valleys.

This has less spread than yesterday but where the fog is in place visibility will be low. There is a dense fog advisory in place for the western beaches and coastal valleys as well as the southcoast that will stay in effect through 9 a.m.

That dense fog advisory is not the only warning on the books. An excessive heat watch has been issued for the interior valleys and will last through Monday Morning. Today's highs climb a few degrees above yesterday. Upper 90s and a few triple digits are expected in the interior valleys, 70s in the coastal valleys and some beaches hanging onto the 60s.

Temps will increase dramatically Thursday and will stay extreme through the weekend. Here is a look at some of the concerns that come with that heat.

An excessive heat advisory is in place for the interiors starting Thursday Morning and lasting through Friday Morning.

Friday morning the excessive heat warning kicks into place and will indicate the peak heat lasting though Monday morning. All these advisories relate only to the interior of both San Luis Obispo and Santa Barbara counties.

For the excessive heat warning, dangerously hot conditions with temperatures 100 to 110 are expected. Little to no relief is expected at night with lows in the mid-60s to mid-70s.

Common sense precautions should be taken already for the heat. Those precautions include staying hydrated, avoiding the peak heat of the day, and paying extra attention to children and the elderly.

Even though temperatures should drop a little early next week the climate prediction center is calling for temperatures to continue to be warmer than average in their 8 to 14 day outlook.

The reason temperatures will be so warm is that a ridge of high pressure over the four corners region builds back into California. The increasing high pressure will lower the marine inversion. That lower inversion means very little access to cool air in the interior.

It is important to note that beaches and coastal valleys will be spared from this heat wave and are not included in any advisory. Night and morning marine clouds we'll visit those areas and act as a buffer against the interior heat. I like good daily clearing near the coast.

This week coastal highs will range between the 70s to mid-80s. Beaches will see daytime highs in the 60s and 70s. South Coast temperatures will be in the 70s and 80s.

Have a great day Central Coast and be sure to stay cool!
