I walked out this morning into a white and frosty world to discover lots of interesting patterns in the land.
What direction are we looking in the photo above?
What is the weather forecast?
There has been a sharp frost. The crystals on the ball show that this was a hoar frost, a sign there have been clear skies overnight.
This is no guarantee of good weather to come, but it does make it more likely.
The frost has melted on one side of the basketball. This side must be the SE side as the sun rises in the SE in midwinter. SE is to the left as we look at this photo, therefore…
We are looking SW.
