Area Forecast Discussion National Weather Service Key West FL 1024 PM EDT Fri Jul 10 2020

DISCUSSION. Currently - A trough over the eastern United States reaches southward through the Florida Peninsula. This has split a ridge across the Keys. As a result, winds are light and predominately out of the southwest to west. The proximity of the trough has resulted in a broad cyclonic flow across our area. While convective activity has been isolated in coverage, through the evening, they lingered over and near the island chain. Recent trend has been downwards, with only a few showers across the upper Keys and across the Florida Straits.

Short Term Update - There will be no significant changes to the synoptic setup across our area through the overnight period. Surface winds generally be light trending to a more westerly flow. Broad cyclonic flow will maintain at low chance of showers and thunderstorms. The main offsetting factor will be the relatively weak flow. That also means once a shower moves it, it often takes awhile to move out.

MARINE. A trough over the eastern United States reaching southward through Florida will maintain light winds becoming primarily westerly overnight. Only minor adjustments made in the evening marine update.

AVIATION. VFR conditions expected at the island terminals. With that said, there will be a chance for periods of sub VFR conditions due to isolated to scattered showers and thunderstorms. Winds will be light becoming mostly west.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
