Area Forecast Discussion National Weather Service Key West FL 1019 PM EST Sat Jan 16 2021

DISCUSSION. High pressure centered over the southern Gulf of Mexico supports gentle to moderate northwesterly breezes across the Florida Keys. There is a bunch of cloud cover across the islands, both high cirrus and low-ish stratus, the stratus based right beneath the healthy inversion sampled by the 00Z KKEY RAOB. The high will lose continuity overnight as it slides east, degenerating into a fractured ridge axis. The northwest to north breezes will steadily decline overnight. Temperatures in the lower 60s will fall a few more degrees, with some locations touching the upper 50s. No changes needed or forecast.

MARINE. Small Craft Advisory in effect for the coastal waters west of Rebecca Shoal due to west to northwest swells as high as 7 feet. A pressure ridge will build eastwards across Florida tonight. A moderate west to northwest wind surge ongoing due to day time heating over Florida should abate after dark, after which light breezes will shift northerly. Breezes will slacken further on Sunday as the ridge axis shifts into the Keys. Another high pressure center will move east along the northern Gulf Coast Sunday through Monday, with gentle north to northeast breezes prevailing across the Keys. This high will strengthen over the Southeastern United States Monday night and Tuesday, with freshening northeast to east breezes over the Keys waters. The high will then settle slowly southward across the Florida peninsula on Wednesday, allowing breezes to relax.

AVIATION. Stratus layers will be off-and-on overnight based at 040-050, right at the large inversion sampled by the 00Z KKEY RAOB. Northerly breezes will tend to go variable Sunday afternoon.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
