Now the sky is cloudy and hazy and I suspect that much of what I'm seeing is man made. I checked the weather forecast and it is supposed to be partly cloudy today. There wasn't a cloud in the sky at sunrise but part of this could be natural clouds that have moved in since then.

I can't prove it but I suspect that the national weather service changes their forecast for certain areas based on the level of spraying that is scheduled to take place. That way what people see in the sky is not too different from the forecast and they are less likely to be suspicious.
