Regarding Juston and Greg's discussion - while it is true that TOR warnings are often not issued for cells that are known to be elevated, I do think that one way to reduce the FAR would be to take other aspects of the environment into consideration, e.g. things such as LCL. I have seen cases where storms with strong rotation in environments that were favorable for supercells but not so much for tornadoes were TOR-warned over and over again but never produced. For example, the storm I chased May 12 in southwestern MO was TOR-warned for better than 2 hours but never produced. It was a gorgeous supercell with funnel clouds and numerous ground-hugging wall clouds, but it produced not one tornado. Of course hindsight is 20-20 and there may have been good cause for at least some of the warnings - the meso did look impressive on radar - but I wonder if this storm (which, incidentally, occurred in a severe watch, not a tor watch) should have been warned as readily as a similar-apppearing storm (on radar) in an environment more favorable for tornadoes. This is the kind of situation where I think the CYA pressures come into play.
