The water vapor content is 82% of maximum saturation level, for the air, at 100%, or above it has to rain.
At 14 degrees, the air gets compressed enough to form dew (on the grass).

Humidity 82%: Means that the air contains 82% of the total water vapor that it can possibly hold at that temperature. When it gets to 100%, you're going to be in fog or a cloud if there's sufficient cloud condensation nuclei present. The amount of water vapor that the air can hold increases with temperature...so the humidity value generally is highest in the morning (when it's cool) and lowest in the afternoon (when it's warmest).
Dewpoint 14°: At the time of that reading, the actual air temperature would have to be cooled to 14° in order for the (relative) humidity to become 100% and thus have condensation to occur. Condensation would occur because there is too much water vapor in the air--the air has cooled too much to support it, forcing the extra water vapor to condense on stuff.

Relative humidity is the measure of moisture in the air and used to be determined by the percentage difference between an ordinary thermometer (dry bulb) and another that had its bulb covered in wet muslin (a wet bulb thermometer). The ability of air to hold water varies with temperature and atmospheric pressure. The warmer the air, the more water it will hold. So, if as the temperature falls, the air has to give up some of the moisture and this temperature is the dew point.

The dewpoint, or dewpoint temperature, is the temperature at which the temperature at which the liquid water, or dew, evaporates at the same rate at which it condenses. The dewpoint is an absolute measure of moisture in the air. This is what meteorologists use.
Humidity is a relationship between temperature and absolute moisture in the air. In other words, it is a comparison between temperature and dewpoint temperature.

humidity is the moisture in the air so for a day with 95% humidity it is almost certain to rain. Dewpoint is the temperature when dew forms because dew only forms on cold days and at night when it is cooler.

No one actually answered the question. Do you live in a cold place, cause in order to have 82% humidity and 14 degree dew point, it has to be below 18 degrees or is it Centigrade?

Humidity in percentage is the amount of moisture trapped in the air. The dew point is the temperature at which this moisture will begin to condense out of the air. The two factors you just mentioned DO NOT go together.

The air is comprised of 82% water.
Dewpoint is the temperature where water will be released from the air (like it forms on a cold glass of beer).

It's going to be a bit sticky.
