It depends. It depends how cold it is otherwise, and how long the sun shines. The day that photo was taken, even the icicles weren't melting in sunshine. And if the ground is warm and the air is warm, snow can melt in the dark.
When you make a statement, think about whether it could easily be made more solid, more reliable.
- Sunshine can melt snow.
- Sunshine might melt snow.
- If it warms up today, that snow might melt.
