How about applying a stream of hot air (a hair drier-type device)?


Last winter, after a nasty ice storm, we tried the hair dryer and it
was worthless. The wind just blew the tiny stream of hot air away. A
friend used a propane heater with a big heating duct and set up some
sort of a small hood to hold the hot air in, it worked for him.
