weather forecast website recommendations?

Most of these sites are just driven off a model output and the location you search for just pulls data for the nearest grid point on the model.

Most sites use the GFS model, yr.no use the ECMWF model, so tends to be more accurate especially for Europe. However they are only as accurate as the model forecast so have times where they are less accurate and more accurate.

For Ireland, Met Eireann is your best bet as they have customized written forecast and understand the nuances of forecasting for Ireland, some other sites who offer written forecasts for Ireland may also be of use.
