After reading Bev's great discussion, I decided to put some numbers on
the moisture vs. temperature vs. relative humidity.  From a SI
psychrometric chart, I put together the following summary table of
moisture content (g water vapor / kg dry air):

 % Rel   |      Temperature      |
Humidity |  25C  |  10C  |  5C   |
---------+-------+-------+-------+
   90%   |  18   |   7   |   5   |
---------+-------+-------+-------+
   50%   |  10   |   4   |  2.5  |
---------+-------+-------+-------+

As Bev pointed out, an air-conditioned storage room (lower temperature
and humidity) can do wonders.

Be careful at assembly, low humidity is BAD for ESD!
