Looking at the local weather before I went to bed, the forecast was for a low of minus-7C.
One thing I knew is that I would be ice-scraping the following morning and that, with no surprise, was the case.
As you can see in the video, I switched the kettle on and then went off to put my fishing gear in the car.
After I had done that, returning to the kitchen the water was still boiling.
In reference to the video, you can see the sunrise as well.
