Over the last week one thing has come to mind is if rain falls from
clouds into frezzing air at lower levels can it turn to snow or will
it supper cool or fall as some sort of grapple / hail?

It would normally supercool and fall as "freezing rain", turning
instantly to ice on hitting the ground (assuming that that is also below
freezing).
