Area Forecast Discussion National Weather Service Key West FL 409 AM EDT Tue Apr 7 2020

DISCUSSION. CURRENTLY. Under partly cloudy skies and variable winds of around 10 mph, temperatures are in the mid to upper 70s along the Florida Keys. Meanwhile, local radars are detecting a few sprinkles on the coastal waters north of the island chain. On our marine district, winds are east at 13 knots at Carysfort Reef Light to northwest at 11 knots at Smith Shoal Light.

SHORT TERM. (Today through Thursday night) A weak area of low pressure aligned from South Florida to across the Florida Keys will dissipate today, Beyond that, a high pressure ridge axis lying across South Florida and into the Southeast Gulf of Mexico will sag southward into the Straits, and near the north coast of the island of Cuba. Precipitation wise, with the close proximity of the trough and mesoscale forcing on South Florida this afternoon, 10 percent rain chances will be inserted for the Lower and Middle Keys with 20 percent pops in the Upper Keys. Beyond that, a deepening and strengthening region of high pressure building across the Sunshine State should preclude shower activity. Daytime highs will average in the mid to upper 80s and overnight lows in the mid to upper 70s.

LONG TERM. (Friday through Monday) In response to a retreating high pressure system into the Atlantic Ocean and lower pressure moving into the Gulf of Mexico, moisture will slowly be on the increase with a deepening and strengthening south to southwest trajectory. With that, 10 to 20 percent rain chances will be kept Saturday night through early next week. Keep in mind, a predominate south to southwest flow should limit shower activity during the daytime due to a Cuban shadow. Outside of any rainfall, daytime highs will be generally in the upper 80s with overnight lows in the upper 70s.

MARINE. For the most part, light to gentle winds will prevail on all Keys coastal waters for the balance of this week, but with gentle to moderate winds adjacent to the Upper Keys during the late afternoon and evening beginning later this week.

AVIATION. VFR conditions will prevail at the island terminals through 8/12z. Winds are expected to remain light and mostly variable amid a weak pressure pattern (but favoring the northwest early this morning).

CLIMATE. In 1950, the daily record cold high temperature of 67 degrees was recorded in Key West. Temperature records date back to 1872.

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.
