The small hygrometers I linked to will sit right on a window sill. Would be a good way to check the air temp right at the windows. If the dew point (not relative humidity) at the window is 50F (pretty dry) and the temp on the inside of the window is 40F, you're going to get condensation unless you have air flowing over the window. Just as when you take a cold can of beer out of the fridge and let it sit on the counter. Condensation will happen.
