Trolltunga and weather

I’m looking at hiking Trolltunga next Sunday. However, it looks like the weather forecasts rain for much of the day (https://www.yr.no/en/forecast/daily-table/1-80533/Norway/Vestland/Ullensvang/Trolltunga).

I know the rain will make the hike more difficult. Also I’m worried that the views won’t be good at the top. However, unless it’s completely unmanageable I’d like to still do it. Is it a bad idea? Should I still go for it?
