What would the relative humidity of that air be if you brought it inside your house and warmed the air to 21°C?
This question show how relative humidity changes as cold, dry outside air is brought inside and warmed. Figure 12.1 shows that as air warms, the maximum specific humidity increases. Therefore, if the air warms but the amount of water vapor stays the same, its relative humidity decreases.
