Temperature and bathroom scales

Does temperature (ambient) affect the reading of an analog bathroom scale?

The reading I'm getting on my scale just dropped by 3 or 4lb, coinciding with a sharp change in air temperature (from 60F to 90F). I know these things are not perfect to begin with, so I could just chalk it up to the scale being quirky. (One day this winter, my weight randomly shot up by 3 or 4lb, and stayed there.)
My level of hydration hasn't changed, so I'm not blaming water (even though it seems a reasonable explanation if hot weather = sweat). I try to maintain a steady water intake.
