If you're looking for a graph that shows more than a projected minimum/maximum for every day, take a look at Foreca's 15-day forecast page [0]. It shows percentile lines for the forecasted minimum and maximum, which give a much better idea of what to expect. It also forecasts global vs. local precipitation. Unfortunately it is only available in Finnish.
