Hail?
rain because if its above freezing then it wont be snow or freezing rain because they would freeze below freezing and not above freezing:)
rain
Freeze thaw is caused by the temperature and the amount it drops below freezing. If it then warms up the crack with enlarge. If this happens again then it will continue until the rock is broken.
Freezing rain can come from Cumulonimbus and Nimbostratus clouds, but the clouds are not responsible for the freezing rain. If the precipitation falls from the clouds as snow it must pass through a warm layer of air to melt the snow flakes into rain drops. Then the raindrops must pass through a frigid layer of air that super-cools them. Finally, the rain instantly turns to ice if it lands on a surface that has a temperature below freezing. Then you know you have freezing rain. (see Related Link below for more detail on freezing rain.)
Places such as most of Antarctica are covered with a permanent layer of ice. In other places, ice only forms when the temperature drops below freezing. The ice formed when this happens in non-permanent ice because it is only temporary.
Depending on the temperature, water drops that fall when the temperature is below freezing can become sleet, ice, or snow.
Water drops that fall when the temperature is below freezing, fall as SNOW . Water drops that fall when the temperature is above freezing fall as RAIN .
The usual term is "sleet".
Snow
The temperature only drops below freezing occasionally.
Usually the humidity is extremely low when the temperature drops below freezing, because almost all of the water is frozen out of the air.

If it freezes in the air, it is called sleet (ice pellets). If it freezes on contact with cold surfaces, it is called freezing rain (called glaze in the UK).
frost
frozen dew
It is impossible unless the temperature drops below freezing at night.
Fresh water (for instance) will freeze and turn to ice when the temperature drops below freezing point. The ice will thaw (melt back into water) when the temperature rises above freezing point.
