Area Forecast Discussion National Weather Service Key West FL 307 PM EST Tue Nov 28 2023

New DISCUSSION, MARINE, AVIATION

DISCUSSION
Issued at 300 PM EST Tue Nov 28 2023 The Florida Keys are having a quiet afternoon. GOES 16 Visible satellite imagery shows a rather dense cirrus deck slowly encroaching on the area from the north. Temperatures along the Island Chain are in the mid 70s with dew points in the lower 60s.

Strong surface high pressure centered over northern Mississippi and western Tennessee combined with lower pressure over the Caribbean is creating for a healthy pressure gradient across the Keys. This is resulting in north to northeast winds currently 10 to 15 knots for surrounding nearshore waters. Also, where the gradient is a little stronger winds are north to northeast 15 to 20 knots at Sand Key. Along the Island Chain, the Middle and Upper Keys are observing north to northeast 10 to 15 mph with the Lower Keys near 15 mph.

FORECAST
Surface high pressure initially over Mississippi and Tennessee will continue to dominate the weather pattern for the next few days with near nil rain chances. The only caveat will be elevated breezes over the next few days as the high slides across the remainder of the Southeastern United States and moves into the western North Atlantic late week through the weekend. North to northeast breezes tonight and Wednesday will shift to northeast to east Wednesday night and Thursday before continuing to veer to east to southeast for Thursday night through the weekend and into early next week. As the high moves into the western North Atlantic, the east to southeast flow will result in moisture undulations moving around the southwestern periphery of the high.
This will lead to slight chance of showers returning to the forecast for Thursday night through the weekend and into early next week. Also, in conjunction with the increasing moisture, surface dew points will be on the rise (lower to mid 70s) making it feel more summery outside to start December and the last month of 2023.

Lastly, there are indications of a stronger front to push through the Keys towards the middle of next week which will bring another round of cooler, drier, and less humid weather. Confidence is average on this front pushing through. Stay tuned.

MARINE
Issued at 300 PM EST Tue Nov 28 2023 A Small Craft Advisory is in effect for the Gulf of Mexico including Dry Tortugas and Rebecca Shoal Channel, Straits of Florida from Halfmoon Shoal to 20 NM west of Dry Tortugas out 20 NM and Straits of Florida from Halfmoon Shoal to 20 NM west of Dry Tortugas 20 to 60 NM out. Small Craft Should Exercise Caution for Increasing Winds (SCEC) are headlined for tonight through the remaining coastal waters. Small Craft Advisory conditions look to slacken overnight before a resurgence Wednesday morning potentially resulting in another short-fused advisory for the same areas. From synopsis, high pressure initially over Mississippi and Tennessee will shift east across the Southeast United States into the western North Atlantic over the next several days.
Moderate to fresh north to northeast breezes will shift to the east to southeast and diminish as the high moves into the Atlantic.

AVIATION
