Some people need to calm down.
You know weather is unpredictable. That's partly why we love it.
Forecasters try their best to predict weather. It's what they do for a living. They are not there to trick or frustrate you. I am sure they feel just as surprised when the weather does exactly the opposite of what they expect.
I for one am grateful of the time they dedicate to this site. They are human like the rest of us and are bound to get it wrong sometimes, but for the most part they do a great job.
