Recently heard of 2 flights to same destination... Couldn't leave because TAF was calling for 1/4sm. 4 hour delay for new TAF.

New TAF came out, legal to depart. Ops holds flight, afraid flights still won't get in (METAR 1/2sm vv200).

Wait another 30 for new METAR: 3sm / 300ovc. 10 minutes later ops cancelled them both.
