what can be the temperature for freezing rain?

Answer 1

Typically, it's the mid-level temeprature that's important, becuase if it's above freezing, but areas on the surface are at or below, the mid level temperature above freezing will causwe the snow to melt to plain rain, but freezing on the surfaces on the surfaces.

Answer 2

Near the surface you're going to want temperatures near freezing or anywhere below. It's aloft that matters. For freezing rain, you need a depth of above-freezing air that is sufficient to melt the ice crystals into rain droplets. They then freeze on impact when they arrive at the surface. Usually the air temp near the surface is at or below freezing, but the rain drops do not have enough time to freeze before contacting the ground.

Answer 3

You should watch out for freezing rain anywhere from 32 degrees to 35 degrees. The rain may not be frozen when it is falling at higher temperatures, but if the ground is frozen or lower then 32 degress when the rain hits it will freeze. You can especially see this on highway overpasses - rain will usually freeze on a cement overpass when it is cold and cause ice and accidents.

Answer 4

Any temperature above freezing. It falls from warm air above and doesn't freeze until it hits a surface that is below freezing.

Answer 5

The hail (that is what frozen rain drops are) may have a temperature lower than 0 degrees celsius when they hit the earth's surface. But as they melt, they more or less reach 0 deg Celsius.

You may need to actually measure by an experiment.
