GMZ005 Synopsis Issued: 418 AM EST Wed Nov 11 2026
Synopsis...
High Pressure Across The Western North Atlantic Northeast Of The Bahamas Will Slide East Through The Day As A Surface Low Moves Into The Great Lakes Region And Strengthens. This Will Allow For East To Southeast Breezes Slacken Through The Day And Further Slacken This Evening, While Becoming More Southerly. As The Low Moves Out Of The Great Lake And Into The New England States, An Attendent Cold Front Is Poses To Pass Through The Florida Keys, Late Thursday Into Early Friday. This Will Result In Breezes Quickly Becoming West To Northwest And Gradually Freshening. A Period Of Fresh To Strong Breezes Is Possible Friday Night Into Saturday Morning Before Briefly Slackening. A Reinforcing Front Late Sunday Will Bring Back The Potential For A Prolonged Period Of Fresh To Strong Breezes.
