Good morning, Central Coast! Happy Friday, as we head into the weekend staying cool is the name of the game. Let's dive right in!
The marine influence that has kept coastal valleys and beaches on the cooler side is sticking around this morning, just to a lesser extent. The marine layer took a while longer to reach beach communities and will have less extent with its cooling ability today. There will still be some communities with limited visibility for the morning commute.
Temps today by the coasts will be a few degrees above normal for this time of year with beaches in the 70s, coastal valleys in the 80s and the Santa Ynez valley climbing into the 90s.
The interior valleys will be the focus where highs are climbing towards dangerous levels. San Miguel is surging towards 110 while the rest of the interior valley locations will be closer to 105 today.
There are many advisories in place due to the heat wave, they are kind of like nesting dolls — most interior valley locations have several advisories concurrently in place. Despite the confusion that adds they all mean the same thing: it is going to be dangerously hot in the interior valleys.
Firstly there is a excessive heat watch in place across the region and will stay in effect through 10 a.m. Monday morning.
To kick off the day interior valleys are under a heat advisory through 10 a.m. Friday morning. This is a lower-end advisory for heat concerns and will be replaced by an excessive heat warning Friday morning.
The excessive heat warning is the highest elevation warning that can be issued relating to heat. In this case, it refers to not only the daytime highs reaching 100 to 110 degrees or more but also the concern that overnight lows may not offer much relief to some.
The Santa Ynez Valley will enter a heat advisory Friday morning until Sunday at 10:00 p.m. All the advisories are to heighten your awareness of the heat and urge you to take precautions against it not only for yourself but for others and for any animals you may tend to.
This heat wave inland is caused by a ridge of high pressure which is still amplifying over the western United States. The highest amplitude of the jet stream ridge takes place over the weekend and correspondingly we will see the highest temperatures.
It is important to note that not all locations will experience a heat wave. Beaches and near coastal valleys will still have some access to marine cooling though that cooling may diminish a little during the anticipated warmer weather inland. Coastal valleys will ultimately warm into the 80s to near 90 degrees though some coastal valleys will remain in the upper 70s with the south coast of Santa Barbara County also seeing temperatures in the upper 70s and low 80s. Night and morning low clouds are possible in these areas and even if those clouds burn off or are mixed out submarine cooling will still take place. All these locations are places to beat the heat during this heat wave.
The ridge of high pressure over the West takes a dent from a trough moving into the Pacific Northwest early next week.
Wednesday and Thursday interior temperatures probably drop under 100 degrees but quickly return too hot temperatures to close the week as another heat wave is anticipated. The climate prediction center expects the second half of the month to be warmer than average.
Have a great day and a wonderful weekend Central Coast!
