AMZ400-122130- Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm- 323 AM EDT Wed Jun 12 2024 .SYNOPSIS... Weak low pressure moving slowly northeastward across Tampa Bay early this morning will cross central Florida today, emerging over the Atlantic waters near Daytona Beach by this evening. Meanwhile, high pressure will briefly wedge down the southeastern seaboard today, resulting in strengthening onshore winds later this morning and this afternoon throughout our local waters. Showers and thunderstorms today will mainly be confined to the waters from St. Augustine southward, with showers then spreading northward overnight as low pressure crosses the Gulf Stream waters adjacent to northeast Florida. Periods of showers and thunderstorms will remain possible across the northeast Florida waters on Thursday and Friday as a frontal boundary remains stalled over our local waters. This boundary will briefly shift southward on Saturday before a stronger high pressure center wedges down the southeastern seaboard on Sunday. This weather pattern will result in decreasing chances for showers and thunderstorms on Saturday, followed by a surge in onshore winds on Sunday that will increase chances for showers and thunderstorms throughout our local waters. .GULF STREAM...
