Blocking High Pressure by Dave Breckenridge

The recent synoptic setup lately provides us with a good example of a blocking high entrenched out in the Atlantic.  A blocking high is simply an area of high pressure that is relatively stationary for an extended period of time.

The series of surface maps below show the blocking high staying put through Saturday morning as it blocks and redirects low pressure around the outskirts of the high’s control in the Great Lakes area.

Interesting fun fact-  When blocking highs set up in the right place out in the Atlantic, The Canary Islands get howling winds:)
