Hi nmhamel -we have been in Grindelwald since Wednesday and have found the forecasts on srf.ch/meteo to be the most accurate. I was a bit worried as the prospects didn't look good and i was concerned we'd just be stuck inside but most days its actually been better than forecast - occasional light showers rather than constant rain. It's true the weather the last 2 days has been mixed but as Lucas points out - it changes by the hour. So you have to be flexible and if the weather is ok - just go for it! Prioritise whatever needs clear skies (ie mountain tops) as you might not get another morning or afternoon that's as good - even if 2 days ahead is forecast as good (or bad) that can change. And even fairly late in the day you can still get up to Jungfrau or Schilthorn. We went up to Kleine Scheidegg from Grindelwald at 5pm on Wednesday when it suddenly cleared (as forecast) . We only had an hour or so before the last train back but it was beautiful, hardly anyone there and magnificent views up to the Eiger Monch and Jungfrau (without crowds with selfie sticks...) The breathtaking train journey is part of the experience.
Today's forecast was cloudy with really heavy rain so we used the pool at the sports centre (free with our tourist card) and when it cleared late afternoon again -we headed to Murren as the trains and gondolas run late. It is chilly in the evenings now.
There are lots of things to do locally that don't need perfect weather -all the activities at Grindelwald First, the Trummelbach Falls in Lauterbrunnen etc Grindelwald itself has a good sports centre and the "indoor" cavern.
It's your holiday so only you can decide what's best. It's not a cheap option and if Jungfrau on a clear day is absolutely essential then it's a risk.The day we visited Pilatus was mainly cloudy but it was still amazing and we got moments of sun. In fact most days we've had a bit of everything - rain, sun,cloud, but still managed to do what we've wanted - including nothing some afternoons cos that's what family holidays are for!
