Precipitation every Mon-Wed-Fri

Monday we had that awsome thunder storm as I have already mentioned, Wednesday we had a half hour of snow/ hail stuck right in the middle of a sunny morning, and today there is finally normal like weather; a light rain. I remember a girl commenting to her boyfriend last year arnoud this time that it rained every Friday (appearently they went out together every friday so she had simply made note that every time they went out together last spring, it was raining).
