Just a small nit:
It is possible (and not uncommon) to have low temperature and high
relative humidity.  However, given some amount of water vapor, the
*relative* humidity will decrease as the air (+ water vapor) is heated.
(If the temperature then goes down, the RH will again increase)

During cold weather, indoor air is generally heated, causing the relative
humidity to decrease unless water vapor is added as the air is heated. The
greater the differential in indoor/outdoor air (assuming ventilation is
adequate, and the outdoor air is what is being heated), the lower the
relative humidity will be (for a given outdoor RH) failing any
humidification of the heated air.
