Issued at 1110 AM EDT Tue May 14 2024 The 12z sounding at KEY sampled a weakly veered lower tropospheric profile, along with very dry air above the 925 mb isobaric surface. Visibile satellite imagery is highlighting mostly sunny skies across the Florida Keys island chain as well as the adjacent nearshore and offshore coastal waters. Winds remain a bit elevated, with persistent breezy conditions continuing across the islands at this late morning hour. As high pressure off the Carolinas continues to slide offshore and a weak frontal boundary nudges southward over the Florida Peninsula, winds will slowly slacken over the next several hours. The main story this afternoon will be yet another very warm day, with highs topping out near 90F, and dew points in the upper 70s. Besides extending the Small Craft Advisory a bit longer for the marine zones, no changes proposed for this late morning update. && .MARINE... Issued at 1110 AM EDT Tue May 14 2024 A Small Craft Advisory remains in effect for all Florida Keys coastal waters. Breezes will slacken through the early afternoon hours. An area of high pressure will slide further over the western North Atlantic, resulting in generally gentle to moderate southeast to south breezes through Saturday. A series of surface low and surface high pressures will transit through the region, resulting in fluctuating breezes at times. A threat for isolated thunderstorms will return starting Wednesday night. && .AVIATION...
