You may not know this but one of the inventors of the first electronic computer was a physicist with a passion for predicting the weather. He figured that if he could just build an electronic calculator that was powerful enough he could use all the existing weather data and some special formulas to predict the weather. It is therefore no irony at all that today we have quite a few super computers, all around the world, using electronic weather models to predict the weather.
But how do you find the best and most accurate weather for our area?
You could start with the National Weather Service: Weather.gov/
Then there's a lot of commercial weather sites you could check out like these:
Lifehacker.com claims that these are the five best weather websites. Maybe you should check them out too?
Outside the United States you could try the
World Meteorological Organization
And if that's not enough there's all those news websites that also offer weather forecasts.
As for which site is the most accurate, that will come down to old fashioned trial and error on your part. You'll have to check out some of these sites and see which ones you like. Some things to look for: easy to follow layout, easy to use, and accuracy.
