This is Luxembourg. In Luxembourg you can have a day of relative sunshine where you even plan to leave work early and get to the Lake in Remerschen in 30 mins for a quick dip.
Until, that is, the storm comes along. One huge rumble in the jungle of clouds and your dreams are shattered. Or wet. Wet dreams. Wet with the sudden torrential downpour that makes sure that any trip to the lake is definitely cancelled.
