Dangerous heat: More triple digits expected Friday and Saturday

Good morning, Central Coast!

We made it to the end of the week, but we are far from the end of our extreme heat wave. Let's dive right in.

Yesterday highs pushed into the triple digits, even along coastal valleys where strong compressional heating occurred to drive the high in San Luis Obispo to 101 degrees.

Today the set up is the same and temps are once again expected to warm into the triple digits in many communities. It is all driven by offshore winds in the night and morning hours, this sets up the day for dry warm air, abundant sunshine and minimal marine influence. We’ll see offshore wind averaging about 15 mph but some local gusts could exceed 20-25mph Friday morning. This is enough to bump our temps but thankfully much less than the strong Santa Ana event that is setting up to our South.

Today's temps will once again be dangerously hot in some spots. Interior valleys will be in the upper 90s and some triple digits. Coastal valleys will be in the low 90s for the most part. San Luis Obispo is annother story though, the offshore winds are helping to compress already hot air as it pushes down the Cuesta Ridge and will heat those temps up even more. I would not be surprised if we surpass 100 degrees again today.

Beaches will be in the upper 70 and some 80s.

Thanks to all this heat a *heat advisory* has been issued for the region. Take caution today as heat related illnesses are possible.

All of this is thanks to the huge ridge of high pressure that has set up over the west coast.

The high pressure will slowly push to the east into the weekend. Temps are set to rise a bit Saturday as more southerly winds push in but that will be a small change. The bigger change comes Sunday as the ridge pushes far enough east while a strong cold front tees up behind it.

The cold front will bring us onshore flow once again, dramatically cooling temps. It will take us a few days to cooldown but by Tuesday many temps will be at or below normal fot this time of year! Yay!

There will be some warming next week once again but it will be much more moderate than today.

Have a wonderful weekend Central Coast, and be sure to stay cool!
