Cooling air below the dew point will result in the water in that air coming out of solution to deposit itself on surfaces. We call that dew. Certainly as the temperature continues to fall, it may even cause rain (if it isn't too cold).
Temperature cannot drop below the dew point. If it does drop to the dew point, the air will become saturated and some of the moisture will condense in the form of fog or clouds.
When its temperature falls below the boiling point.
Increasing the temperature up to the melting point.
As snow falls it will evaporate if the surrounding air is drier, and the energy required to turn water or ice into a gas is taken from that air and the air cools. Eventually it cools to saturation, where the temperature and dew point are equal or very nearly so. This temperature - where the dew point and temperature "meet" if you increase the relative humidity to saturation - is the wet bulb temperature.
Ice will melt if the surrounding temperature rising above freezing point.
That happens because any heat that is added to that melting material will be used to cause further melting, until there is nothing left to melt, at which point the added heat can raise the temperature. A solid melts at its melting point; it does not get hotter than the melting point without melting, that's why it is the melting point.

there will be no precipitation in the morning

The triple point of water (where you can boil water yet not melt ice; this can only happen with the correct temperature and pressure)

If the temperature is 18 C and it falls to 25 C, the temperature would then be -25 C (minus 25 Celsius). The freezing point on the Celsius scale is 0°. So minus 25 Celsius would be very, very extremely cold!
Ice will melt if the surrounding temperature rising above freezing point.
It occurs when the temperature falls below the freezing point of the substance being studied, after adjusting for the relevant pressure,
Anything above the freezing point, 0* Celsius. Below freezing point, rain turns into snow, sleet, slush or hail.
Ice will melt if the surrounding temperature rising above freezing point.
