Threatening clouds

At lunchtime today, these clouds were over towards our home. There was plenty of lightning too. I wondered whether my windows were closed but couldn't do much about it, as my lunch hour was nearly over.
Although we only had a small downpour in Narrabri, it must have poured at home, 20km away. We had 20mm and ... Yes, our bedroom window was open. The floor and bedside mat were soaked. Even the bed was wet ... luckily not on my side ;) Hopefully the new gyprock wall holds up.
