Blowing hot and cold

Time magazine has an article titled "Another Blizzard: What Happened to Global Warming?" which is an example of a weather-is-not-climate article. I have no argument with people pointing out that today's weather in X neither proves nor disproves global warming/anthropogenic global warming/climate change*. What worries me is that it doesn't make sense. The beginning of the fifth paragraph says:

But as far as winter storms go, shouldn't climate change make it too warm for snow to fall? Eventually that is likely to happen — but probably not for a while. In the meantime, warmer air could be supercharged with moisture and, as long as the temperature remains below 32°F, it will result in blizzards rather than drenching winter rainstorms.

So, warm air becomes supercharged with moisture as long as it is below 32°F? As far as I know, air at less than 32°F will hold as much moisture as air at less than 32°F has always done. Warm air must surely mean air above 32°F in which case it is not below 32°F. In which case this snippet is nonsensical.
