Area Forecast Discussion National Weather Service Key West FL 941 PM EDT Sat Mar 28 2020

DISCUSSION. A very strong dome of mid-upper level high pressure is sitting over the Eastern Gulf and Florida Peninsula this evening. The observed 500 mb height on the 00z KEY sounding was a whopping 5930 meters, which is very high. In the sounding, this has manifested itself with an uncommonly low subsidence inversion near 2500 ft MSL. The inversion was extremely sharp and strong, with the radiosonde observing a temperature rise of 7C in just 200 feet as the balloon passed through the subsidence inversion. The 850 mb temperature of 22.4C is very warm. It's usually hard to get much cloudiness and almost impossible to get showers with 850 mb temps of that magnitude. No wonder the afternoon cumulus over the islands were so pancake flat today.

High pressure aloft will not let up through Monday, finally showing signs of weakening around Tuesday. So there will be little day-to-day change until then. A surface ridge axis from the Atlantic across Central Florida will continue to support moderate to fresh east-southeast breezes over the waters.

MARINE. Have expanded the Small Craft Advisory over the Straits to now include the portion of Hawk Channel adjacent to the Lower Keys, based on 19 kt sustained winds at the land-based Key West Airport. Have also expanded SCEC headlines to include the deep Gulf waters based on sustained 19 kt winds at Smith Shoal Light. In the diurnal ebb and flow of easterly breezes, these winds should reach their late evening peak over the next few hours.

From synopsis, high pressure centered between the Bahamas and Bermuda will lumber a bit to the southeast over the next few days. Moderate to fresh east to southeast breezes are expected across the coastal waters of the Florida Keys through Monday. Breezes will turn to the south Tuesday and Tuesday night as the high pressure system recedes east into the Atlantic. A weakening cold front may push through the island chain Wednesday or Wednesday night. Strong westerly breezes are possible Wednesday evening adjacent to the Florida Peninsula, followed by diminished breezes Thursday and Thursday night.

AVIATION. Very strong high pressure aloft will allow little more than SCT coverage of fair weather pancake cumulus over the next 24 hours. The Key West sounding showed a strong and sharp subsidence inversion near 2,500 feet MSL this evening, so dry and clear above. East-southeast surface breezes will continue.

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.
