Why Weather Forecasts Have Seemed So Inaccurate Lately

Is there somewhere I can see the accuracy of forecasts? I have for years been wanting to be able to see how accurate my local (and not so local) forecasts are. Sometimes I think about compiling the data myself but it always seems to be an overwhelming task.. Also, I am not really sure how even to look at it. Has anything like this been done?

TLDR Trump.
