It is our humble opinion that some modern meteorologists who practice on gullible commodity traders are admirers of Perkins and his quackery 

You can see how I was bearish corn some 40¢ higher than this last April based on our BestWeather Spider featured for all commodities in my WeatherWealth newsletter each week. If anything, look how wet it has been in the western corn belt during the last few weeks (the opposite of what most models were suggesting even a month ago). Now, drier weather is necessary to prevent some disease and fertilization issues to corn and beans.

Luckily, I see more sunshine and a bit warmer temperatures as we head deeper into August with no major, new crop problems.

Now the grain market will be paying close attention to the August 12th USDA crop report. What do I expect? That will be in my newsletter later next week.
