Hey everybody, this is going to be a real quick forecast, but I do have some good news, and no, it’s not because I saved 15% on my car insurance by switching to GEICO. It has not reached 55 degrees all year long, which is amazing really. By this time last year, we had reached 55 degrees 24 times. But it looks as though that streak will end tomorrow. We will see a weak high pressure system with partly cloudy to mostly sunny skies, and this, combined with weak offshore flow, will likely give us temperatures in the upper 50s. We might even see some 60s near the foothills. After that, our showery weather returns, with temperatures slightly below normal and the threat of some of those awesome spring thundershowers that I love oh so much.
There isn’t really much to talk about today. We have seen some strong thunderstorms over the past few days, but those will come to an end. We will see a minor storm on Friday that may cause some instability and some showers, but it won’t be anything major. After that, the storm track will shift southward over central or even southern California and give them some rain, with large amounts of snow in the Sierra Nevada. This picture below shows the upper level air flow at the 300 millibar level. This means this is the level of the atmosphere where the pressure is 300 millibars. It varies, but it is generally around 18,000 feet high. It is forecast on the UW WRF-GFS model at 11 A.M. Saturday.
As you can see, there is a large trough of low pressure with associated light upper-level winds over the Pacific Northwest, with the jet stream dipping down towards California. We will still see some showers and cooler than average temperatures, but there will be less rain, which is good for the people who dislike rain I guess. Unfortunately, if you live in Seattle, you probably like rain, so in my opinion, this isn’t good news. But if it is in the summer, I want sun all the way and 90 degree temperatures. Nothing like swimming in Lake Washington.
Yesterday, I talked about nuclear power and how we still need it. I’ve been thinking over it a little bit, and I actually think that Eastern Washington would be one of the best places to put the power plants. Any earthquake energy from Western Washington would largely be dissipated by the time it gets to Spokane or Pullman, and those places also don’t see much in the way of severe weather. Also, this would help us remove some dams and restore salmon populations. I love salmon and fishing btw, so this would be pretty awesome. And it is a large economic opportunity because since this would be one of the safest places in the country to have these plants, we could sell our energy to other places in the U.S., creating jobs and some greenbacks to spend on more important things, like replacing our viaduct (don’t even get me started on earthquakes there), our light rail system, improved agricultural opportunities, and helping make the cities on the eastside more prosperous and larger. If Washington generated all electricity via green energy (hydroelectricity, wind, and nuclear), I would be a very happy person. And although I said I didn’t really like wind power, wind power works pretty well in some places in central Washington. There is a large wind farm by Ellensburg. I still think solar power is our worst clean energy solution.
I’m at the library right now, so I still have a couple minutes before my jazz band class starts. I might as well talk about the huge whirlpool caused by the tsunami in Japan. Take a look at this bad boy!
This whirlpool in a eastern harbor of Japan was formed because of a unique combination of the rushing water and the bathymetry (topography of the sea floor) of the harbor. I hope that boat was ok!
And one more tsunami video. Absolutely amazing stuff. Tragic, but amazing.
Hello everybody, today I am not going to talk about weather. Instead, I am going to talk about nuclear power. The fission and fusion of atoms can cause massive destruction. If I remember right, the largest hydrogen bomb, the Tsar Bomba, which was detonated by the Russians in 1961, had the power equivalent to 58 million tons of T.N.T. Even harder to believe, it was a SCALED DOWN version of a bomb that originally had the explosive power of 100 million tons of T.N.T. As is, the bomb could incinerate the whole country of England. It was around 4,000 times bigger than the bomb that was dropped on Hiroshima. Thankfully, apart from the two that ended World War II (I won’t discuss politics here), none of these bombs have ever been detonated as an act of unprovoked warfare. However, there was considerable scare in the Cold War, when bigger and bigger bombs were being built. And as you can see, there is good reason why. When we discovered Russian missle silos over Cuba, we came as close as we have ever been to a thermonuclear war (thermonuclear bombs, ones involving the fusion of Hydrogen into Helium (like the Tsar Bomba), are vastly more powerful than the fission bombs which break apart Uranium and Plutonium atoms that were seen in Hiroshima and Nagasaki. So in this way, atomic energy can be our worst nightmare.
Some nuclear bomb test (don't know the name)
Tsar Bomba video. Camera sucks, but look at the expanding shockwaves!
Hiroshima (left) and Nagasaki (right)
But atomic energy can also make our dreams of reliable, clean power for everybody come true. I have believed, and still believe, even with all these nuclear crises in Japan, that nuclear power is the way to go if we are going to stop global warming with coal and create clean, cost-effective amounts of energy without destroying the environment like hydroelectricity, wind power, and solar power (not to mention the unreliable nature of them). Nuclear energy has one of the lowest accident rates of ANY industry and has gotten much, MUCH safer. Of course, you shouldn't put nuclear power plants in areas that are prone to natural disasters (as we have recently found out), but still, nuclear energy is clean, reliable, and efficient. When we implement it correctly, nuclear energy is a tremendous gift. I believe it is the only feasible solution to combat global warming and ultimately save our planet.
Let me first explain how nuclear power works. This is a very simplified version, but basically there are fuel rods of Uranium enriched with Uranium 235 which is best for fission. A controlled reaction of fission takes place, and temperatures are cooled by using water. This is the most important part, because if there is no cooling agent, the rods melt and you get a nuclear meltdown. Then, this heat goes to water and creates steam, which then powers turbines. This is what generates prodigal amounts of electricity. Finally, the steam cools in the classic cooling towers you associate with nuclear power plants. Here is a picture of a power plant
Look at all that steam!
As you can see, nuclear fuel generates a tremendous amount of energy. And the amount of fuel used to generate this type of power is tiny compared to coal power plants and hydroelectric dams. And forget about wind and solar power.
However, as we have witnessed with the situation in Japan, there are dangers to nuclear power. First, there was Three Mile Island. Then, the biggest explosion came in 1986, with Chernobyl, killing several thousand people from radiation sickness and causing fallout over a wide area. Now there is the situation in Japan. Nuclear energy used to be very unsafe. Three Mile Island and Chernobyl were not provoked by a natural disaster. Japan has just gotten hit by a 8.9-9.0 (depending on if you trust the U.S. or Japan) earthquake with a resulting tsunami. This will completely devastate even the most "indestructible" structures.
So there is much to be learned from this. Nuclear power is still the key to our future. But we need to protect our nuclear power plants. We need to put them in places that aren't prone to natural disasters. The Great Plains would be a "great" place for these plants. The only thing they really get are severe thunderstorms, and these nuclear plants are built like a tank. They will survive even the strongest tornado. And they can be shut down in advance if severe thunderstorms are forecast.
But putting them on earthquake fault zones? Not a good idea. There is no way to predict when a 9.0 earthquake will strike. And when it does, nuclear plants will be running, the cooling systems will get damaged, and you will have a meltdown.
But if we can find SAFE places to build these plants, away from places with earthquakes, tsunamis, volcanoes, and other events that are hard or impossible to predict, we should build power plants. Coal energy is what will really kill us in the end.
Strangely enough, many environmental groups strongly oppose nuclear energy. But hear me out on this one. I'm a very environmentally-minded guy. Nuclear power is THE cleanest type of power. If we want to save our planet from a much worse fate, we need to invest all of our resources in clean energy.
If anybody that has been affected by the recent events is offended by this article, I am sorry. This is just my opinion. It seems obvious to me that we need nuclear power, but I am just one person, and these events in Japan have affected many people and given us doubts about it. These are just my thoughts and there is no right or wrong in this scenario, and the situation with the plants in Japan is tragic. I wish the Japan the very best in recovering from this tragic natural disaster.
Thanks for reading,
Charlie

I’m actually writing this blog from school right now on Microsoft Word. I can’t actually go through to Blogspot and update it from school, but I think this will do since I can just copy this and put it up when I get home.
First, I want to talk about that windstorm we had on March 10th. I actually pointed out a strong storm in my last forecast that was slated for the 10th (remarkable timing for so long out!) but it came closer than was forecast in that model. It wasn’t that strong, but it followed a near perfect track for giving us strong winds. It rode up the coast, kind of like one of our classic “Sou’westers,” except it had more of a western than southern origin and followed more of a northeast track as opposed to a north-northeast track. Still, it eventually cut right across the Olympic Peninsula and came very close, which, combined with strong southerly upper-level air flow (when I say southerly, that means it originates from the south) and a compact pressure gradient, gave us surprisingly strong winds from a storm that is relatively small by northwest standards.
This picture shows the 2 P.M. visible satellite shot from March 9th. You can see two storms. One is by the Queen Charlotte Islands, and another is offshore southest of the 45N 135W line. Both storms have beautiful bent-back occlustions. Normally, this is a sign of a storm that has reached maturity and is starting to weaken. However, that is not true with our more southern buddy. This guy is just getting started. There is a localized low center, but it gets another burst as it runs into the moisture plume that is heading towards Oregon and interacts with a strong jet stream.
I would use a visible satellite as this storm seems to be shaping up better there, but this was taken at 6 P.M. at night, and there is no light to allow you to see. Therefore, a visible satellite won’t work! As you can see, the storm is developing a much larger occlusion. But as this next picture shows, the visible satellite is a very valuable tool for giving us very close-up details of storms.
This, taken at 10:30 on Thursday (the 10th) shows the storm closing in. It isn't the clearest picture, but you can see the dryish slot offshore. The bent-back occlusion is to the west of that. But this next one is a little clearer.
This one was taken at 12 P.M., 90 minutes later. You can see a "comma" if you look closely. This is a sign that a storm is rapidly developing.
And at 2:45 P.M., 165 minutes later, the storm has crossed the Olympics. The mountains tear the form apart a little bit but we still get very strong winds when this occurs. And we did!
Today, we saw some thundershowers as a cold and unstable air mass passed over the area. We will probably see the same deal tomorrow and the rest of the week before drying down a bit for the weekend. Some more systems will return next week.
And I will talk about the tragic Japan earthquake and tsunami in my next post. One thing is for sure though... we NEED nuclear power. I really hope all this stuff doesn't scare the world. Just don't build nuclear power plants in earthquake-prone areas. But nuclear power is really the only feasible clean energy source that will work for the world for ages to come.
Your reading of this blog makes a contribution to my future. Thank you! Have a good one.
