| Area Forecast Discussion National Weather Service Key West FL 1022am EDT Wednesday August 4 2021 Surface analysis depicts weak ridging over the Florida Peninsula stemming from the Bermuda High centered over the central Atlantic, with a stationary front enveloping the Gulf Coast and the Florida Panhandle. After a wind surge overnight, flow is quickly collapsing across the island chain. The 12z sounding at KEY revealed considerable dry air above 925 mb, but steep low-level lapse rates, a near-surface moist environment, and a decent veering profile. This has allowed a few showers to develop in the vicinity of the Lower Keys, along with several observed waterspouts in Hawk Channel. With diurnally-driven mixing, still expecting the dry air to win the convective initiation battle for the balance of today, and thus no changes are needed or planned for this late-morning update forecast cycle. Marine No watches, warnings, or advisories are in effect for the Florida Keys coastal waters. From synopsis, a weak ridge axis extending across South Florida will lift northward into Central Florida over the next several days. Light to occasionally moderate southeast to south breezes will continue, with near-normal rain and thunder chances. Breezes will freshen early next week as the ridge axis broadens and lifts further northward into the southeastern United States. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None.
