Don't trust the forecasts.
Check the newspapers and the TV on SF1, early in the AM. Unless the forecasts are really awful, expect some sun mixed with the clouds.
If any rain is expected- even the skightest - for accuracy they must forecast it. But, it does not have to cover a large area.
Also, check with the tourist info at beside track 1 in Luzern main tsation.
Weather in Switzerland changes frequently, rapidly, and varies over very small areas.
If it is really really awful, consider a trip to the Rhone Valley, which is very dry, often not cloudy when the rest of Switzerland is awful.
