Today, I will mix it up a bit and go away from the closed low and the rain it will bring to Southern California by Thursday. Today, I will look on the other end of the spectrum, the exceptionally dry conditions in the Northwest.
It is not unusual to be dry for two and a half months in California for the summer into early fall. In fact, it is pretty normal. But the Pacific Northwest? This is an area of the nation that many people think is a pretty rainy place. Some of this is true; some of it is an overstatement. But in reality it does rain in this area fairly often, especially from the Cascades on west.
But since the beginning of August, even a few raindrops have been hard to come by. Below is a table showing some of the major cities along with how much rain has fallen since Aug. 1, what is normal during that time period and what percentage of normal rain has fallen.
These rainfall amounts are more like what one would expect in a desert region. All cities have had an extremely small percent of what is normal during this time, and a couple of places have had no rain at all. These are incredible numbers for this part of the country.
The weather is going to stay bone dry for another two days before changes finally take place. Rain will return to areas west of the Cascades on Friday as a cold front arrives. A second front will move in on Saturday. East of the Cascades, the first front will be mainly dry, but a couple of showers seems likely with the second front. And it looks wetter right on into next week with potentially for some pretty good rain amounts in parts of western Washington early next week.
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.
