Complex and dynamic weekend ahead, with an upper trough, surface trough and front forming a surface low in the convergence zone off the North Coast. This low is expected to rapidly deepen through Sat.

Complex and dynamic weekend ahead, with an upper trough, surface trough and front forming a surface low in the convergence off the North Coast. The initial front now feeds into a deepening trough line off the Mid North Coast (separate to the developing surface low off the North Coast ) which amplifies the fetch of S/SE winds adjacent to the Central NSW Coast.

After a couple of weeks of great waves, the coming outlook is very spring like with average winds and weaker swells.

The current pattern- with weak high pressure drifting across Central NSW and a soft ridge along the coast- will be replaced in emphatic fashion by a much stronger front and trough on Friday, forming a surface low off the Mid North Coast, anchored by a monster high moving into the Bight at the same time. Well to the south of that set-up will be a deep polar low and associated fronts with severe gales to storm force winds generating long period S’ly swells to make landfall over the weekend and into early next week.
