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.
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
A powerful second punch is offshore right now and comes inland during the early morning hours. It will bring moderate to heavy rain for the Friday morning rush.
The main storm will move in off the Pacific Thursday and Friday.
Last year by the end of April the drought in California was very bad. Since then it has become even worse.
