Cecily Tynan doesn’t know what an “Omega block” is

On today’s 6PM weather segment on Channel 6, Cecily Tynan showed a graphic of an upper trough expected to influence this weekend’s weather and incorrectly labeled and described it as an “Omega Block”.

An Omega Block is the result of high pressure and the jet stream takes the shape of the Greek letter Omega. What she showed is a plain old upper trough.

Correctly identifying an Omega Block is one of the ABCs of meteorology.
