Yes! Relief from the current heat wave in California is coming. No, it will not be tomorrow and Saturday. RATS!
The hot weather that has been around all week in all but the beach areas will continue through tomorrow. In fact, many places today are running hotter than yesterday, and tomorrow will probably be even a few degrees hotter than today. It is worth noting, like I did two days ago, that the unusual heat is more out of the deserts than in the deserts. In fact, it has been as hot in the valleys of Southern California as it has been in the Upper Deserts and portions of the Lower Deserts.
The huge ridge causing this heat is expected to weaken, starting Saturday but more noticeably Sunday into early next week. While the deserts may not cool down a lot, the coastal cities to the coastal valleys and much of the Central Valley will see temperatures gradually fall. The change Saturday is not going to be great, anywhere from 2 to 5 degrees lower than tomorrow. It still will be hot by anybody's standard, just not quite as brutal, but by Monday and Tuesday, temperatures are likely to return to near normal.
Later next week, temperatures could trend up again as the ridge tries to build some again. However, right now, the ridge does not look as strong as it is now so I don't believe it will become as hot.
This will make for a very hazardous period for firefighters into early Friday night.
With such high heat and low humidity, the fire danger will be as high as it can get.
For the second time this week, parts of northern California will get some rain.
With such high amounts of water vapor, thunderstorms will bring locally very heavy rain that can cause flash flooding.
Many areas east of the Cascades this weekend will be over 100 F.
some of the moisture from Andres and newly formed Blanca could influence the weather in the Southwest
