Inland heat building fast while coasts remain comfortable

Good Morning Central Coast!
As we kick off the midway point of our week most communities are remaining clear from fog, except along the Santa Barbara coastline where dense fog is building in from the south. That will continue to spread slightly as e move towards sunrise but shouldn't cause too many visibility concerns.
Once the fog dissipates in the early morning we will start to see some dramatic shifts in temperatures. Coastal influence is still keeping coastal valleys and beaches near normal with mild conditions but in the interiors heat is building into the upper 90s once again with low humidity. This is not only increasing the likelihood of heat related illnesses but also increasing fire risk.
This is the first big heat up of the year and it is all happening because a ridge of high pressure is forming in the upper atmosphere, this encourages surface high pressure which squishes the depth of the marine layer keeping the cooling limited to beaches and near coastal valleys.

Over the next few days the coastal cloud dance continues, inland it just looks warm to hot. Wednesday looks to be in the upper 90s again with inland locations warming a bit Thursday thru Saturday to 100+.

Portions of the Central Coast's interior valleys have been upgraded from a excessive heat watch (yellow) to an excessive heat warning (purple). This warning is in place from 10AM Friday Morning to 10PM Saturday Night. Dangerous heat is expected with temperatures up to 105 possible.
I recommend taking heat precautions today, thorough Saturday. Stay hydrated, dress for the heat and limit time in the sun.

The excessive heat warning is an advisory not only about the heat but also to raise awareness about precautions like avoiding the peak heat and heat-related illness. You should also be aware of the activities of children and the elderly and limit your and their exposure to peak heat. Hydration is also a key. Fire threat also increases during peak heat episodes.
Looking for a glimmer of hope, the Climate Prediction Center in their 8-14 day outlook likes temps to be closer to average outside our 7-day forecast. Let's hope so. Lake levels are low, the land is stressed, and it is going to be a long summer (and it isn't even summer yet).
Have a great day Central Coast!
