DISCUSSION: As this week continues to roll on, there is an expectation for the current low positioned over the Southwestern United States and the larger high-pressure system parked across the Central and Eastern United States to somewhat stall out! In the process, this will induce the formation of blocking regimes known as omega and rex blocks. The term "omega block" was coined by its appearance to look like the greek letter omega with a high-pressure system blocked by a low to the east and the west. The term "rex block" is identified a strong blocking high pressure over a weaker low as identified in the graphic below! Very neat synoptic-pattern evolving in the upper-atmosphere without question!
