HI everyone what is the difference between :weather report and weather forcast?
thanks very much

This querstion has been asked many times.
There is a very useful search function at the top of this webpage.
If you type the words
forecast report
into the Google search box at the top of this page, then click on the ‘Forum search’ button (not the Google search button), then you will see a list of threads where this topic has already been discussed.
They should help you.
