I wonder if everyone is experiencing 'cold snap syndrome' that I first heard suggested in the Sullivan and Weese pt/pd  manual many moons ago. The last few days have seen the first colder and drier Canadian air of the season creep down into a large part of the US. Perhaps what is going on is that everyone's papers are adjusting to a different humidity regime, but not in a smooth consistent way. 

Where are you located?
