Beginning Thursday afternoon, April 3, the National Weather Service says, a sub-tropical high-pressure system will move into the South Atlantic states where it will stay through Sunday.

The Positive NAO index phase shows a stronger than usual subtropical high pressure center and a deeper than normal Icelandic low. The increased pressure difference results in more and stronger ...
