Predicting the weather is a little like trying to pick up Jell-O before it sets. There are a lot of molecules up there, all interacting in less than predictable ways.

“Forecasts have been improving every year, but thanks to strides that have been made recently they are on the verge of getting much better,” said Mark Gildersleeve, president of Weather Services International in Andover, Mass., a company known to pilots of all stripes for the last 25 years simply as WSI.
