So, today I had the chance to observe an example of the relative accuracy of buienalarm.nl vs. buienradar.nl
Time: ~13:00
Around 13:00 I wanted to know what the weather was going to be at 17:00, and I noticed that buienradar was predicting complete dryness, whereas buienalarm was predicting torrential rain.
Here are the screenshots:

Buienalarm ~13:00
Time: ~16:00
When I checked again around 16:00, buienradar was showing more or less the same thing, while buienalarm had completely changed its mind!

Buienalarm ~16:00
Time: 17:00
Sure enough, at 17:00 the weather was completely dry. Here is the view from my office window:
Of course this is just a single observation; in another observation, the roles might be reversed. It will take many more comparisons before I can tell if there is a pattern.
