Weather version of Murphy's law

I had a large (5000L) rainwater take installed and plumbed during the week. I am looking forward to being able to water a (small) lawn again, and being able to water vege patch without treking up and down the garden with a watering can.

The weather seems to have returned to the pattern of 'rain 5 days from now' - the 5 days away never actually arrive.

Is there a version of Murphy's Law in operation here? Plenty of rain - until you try and catch it!

Just briefly

The worst storm in decades *was* pretty fierce. Driving through it with 10m visibility and debris over the road was, um, interesting. If we'd known at the time how bad it was we probably wouldn't have set out.

The worst hit areas are only a few km from where we live and we didn't even lose power. Lucky.

It's hardly stopped raining since. Pity the order for a rainwater tank is still sitting on the kitchen table :-(
