Contrary to popular belief electron flow that we refer to as electricity travels (theoretically at the speed of light in a vacuum - 330,000 miles/second) on the outside of the conductor that is carrying them/it. In the case of multi-core cables, as with power transmission lines, the electron flow also follows the helical winding of the cores making up the cable. Point of interest here, at 60Hz the associated elctrical AC sine wave is 5500 miles long, at 50Hz 6600. So in a hundred miles of transmission line there is just 0.02 of the AC sine wave at any given time. No point here - Just a statement :P)
When it gets cold, as in freezing, the electrons travel on top of the ice on the cable - This makes attenuation (leaving the power line and scattering) far more likely as the subatomic "bond" - the weak nuclear force - is already partially broken. FYI - Copper has 29 all electron subatomic particles. 28 are tightly packed around the nucleus, only one is in a high "S-type" valence band orbit. This allows for it to be easily removed, as in elctron flow aka electricity.. OK - That's it for this year - Happy 2012. Let's make this the year of "The Hum Stoppers" instead of the "Hum Hearers"!
