I was having the same problem while trying to redirect from a streaming output source. 

You should use the -u-u (unbuffered) flag with sed and then PIPE the data instead of appending it with >>>> operator (>>>> locks the file and is blocking). 

Instead doing the following works someprogram | sed '/filter/' | tee myfile.txt

someprogram | sed '/filter/' | tee myfile.txt
