Buienalarm vs. Buienradar

So, today I had the chance to observe 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:

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

Sure enough, at 17:00 the weather was completely dry.  Here is the view from my office window:
