The next heat wave arrives Thursday and looks to linger a week, and likely longer.

Our region will join much of the desert southwest with the potential for extreme temperatures between 100 and 110 degrees.
For the Heat Advisory, high temperatures between 95 and 105 are expected. For the Excessive Heat Watch, dangerously hot conditions with temperatures up to 108 are possible. Advisory in place tomorrow, Warning from Friday to Saturday evening. pic.twitter.com/5mXofBuyge

A heat advisory covers Thursday morning into Friday morning, then an excessive heat watch takes over from Friday morning into Saturday evening. Temps ease to 100-103 early Sunday into early next week and thus far no advisories have been posted for that period.

The prolonged heat event again is a risk to public health, and we'll also elevate fire weather concerns throughout the region. Preparedness, diligence, and common sense are all advised during this next heat wave.
Towns and temps for Thursday. Interior temps continue their upward move while coastal areas range from the 60s to the 80s. pic.twitter.com/llWy43tL19

Much like the last several heat events beaches and coastal valleys are not covered in any advisories as temperatures will not be life-threatening, in fact, they'll be mild.
Towns and temps for Thursday...yes, another serious run of heat inland resumes while coastal areas get off easy. pic.twitter.com/CRQj8Blilq

Coastal valleys will range from the 70s to lower 80s as will the South Coast. Daytime highs at most beaches will remain in the 60s throughout the rest of the week and the coming weekend.
Again, the 7-Day tells the tale of inland heat and where to beat it. pic.twitter.com/smj6uXqG9U

The Climate Prediction Center continued to think above-average temperatures are likely in their 8 to 14 day outlook.
The ridge of high pressure rebuilds over The West and resumes interior heat. Like the last few heat events beaches and coastal valleys warm but not by nearly as much as inland areas which can't be touched by marine-cooled air over the next few days. pic.twitter.com/44a7b49W18

The reason for the excessive heat in the interior is the return of an upper-level ridge. Strong ridging in the upper atmosphere redevelops Thursday and the high amplitude ridge looks to remain in place much of next week. There may be some day-to-day variations in the strength of the ridge resulting in temperatures going up and down a little bit but generally, it will be hot in the interior cool at the beaches and warm in the middle.
