Area Forecast Discussion National Weather Service Key West FL 1034 PM EDT Wed Apr 8 2020

DISCUSSION. High pressure aloft and at the surface dominates our weather this evening. A 500 mb high over the northwest Caribbean comes with a flat ridge over the southern Gulf, with the 00z KEY sounding observing a 500 mb height of 5900 meters. Meanwhile, an east- west surface ridge axis is located along the north coast of Cuba. With so much high pressure, the subsidence inversion in the evening sounding was near an uncommonly low 1,300 feet MSL. This barely even gives clouds a chance to form.

The upper ridge will weaken some on Thursday and Friday, but the surface ridge will not go far. Even if the subsidence inversion lifts a few thousand feet, it will still not deepen the mixed layer enough to generate showers. Indeed, Saturday PM is the first time with so much as a 10 PoP in the forecast. Dry season continues. Otherwise, the sunny skies, light winds, and warm air aloft will support well above normal temperatures. High temperatures in the upper 80s should become increasingly common through Saturday.

MARINE. Light westerly flow will prevail through Friday night, thanks to an Atlantic high pressure ridge near the north coast of Cuba. Westerly flow is known for locally accelerating during the late afternoon and early evening around the southern tip of the Florida Peninsula, bringing a surge of 15-knot winds from Florida Bay across the Upper Keys to Carysfort Light. That will be the case on Thursday PM and Friday PM.

Winds will more broadly freshen and veer more southerly Saturday and Saturday night as low pressure deepens across the Mississippi Valley. As a result, a Small Craft Advisory may become necessary for portions of the waters over the weekend. Thereafter, winds will slacken as the aforementioned low pulls away from the region.

AVIATION. Persistent weather will prevail for the next 24 hours, with light west-northwest winds and FEW coverage of fair weather cumulus, if not SKC. The evening KEY sounding showed an uncommonly low subsidence inversion near 1,300 feet MSL, so that will very much limit clouds. Great flying weather for the Keys.

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.
