Siberian High
Matheson was well known for his poetic, almost Shakespearean language on air. He widely referred to "that most dreaded of all meteorological phenomena, the Siberian High" or its counterpart, the "Keep your eye on the Idaho High". Matheson was also known to say things such as "gather ye rosebuds, while ye may" to indicate a sudden cooling trend; while storm clouds were called the "darkling shadows on the weather map". These sat alongside "Mother Low", the "Omega Block" and numerous others.
