Issued at 1005 AM EDT Mon Jun 8 2026 GOES-19 infrared satellite imagery highlights expansive upper- level anticylonic ridging extending from the Gulf eastward to the Bahamas. Meanwhile, at the surface, a weak stationary front draped over the Mid-Atlantic separates a subtropical high pressure cell centered west of the Azores from a continental high over New England. The net sum of these surface features is light to gentle east to southeast breezes for the Florida Keys. The 12z morning sounding at KEY sampled a modestly veered low-level profile, coupled with ample boundary layer moisture, and minimal inhibition. However, low- and mid-level lapse rates appear meager at best, including a number of isothermal to thermal inversions. We will need to monitor for potential island cloud line formation this afternoon, although flow may be a bit too southerly to conglomerate island streamers into anything that produces showers and possible waterspouts. No change proposed to the inherited slight rain and thunder chances for the first period. && .MARINE... Issued at 1005 AM EDT Mon Jun 8 2026 No watches, warnings, or advisories are in effect for the coastal waters of the Florida Keys. From synopsis, a surface high pressure system centered east of Bermuda will support light to gentle east to southeast breezes across the Florida Keys coastal waters through mid- week. A second high pressure system will push into the western North Atlantic by mid- week, maintaining light east to southeast breezes. Rain and thunder chances will be at near-normal levels early in the week, with a potential increase in coverage beyond Tuesday. && .AVIATION... (12Z TAFS) I Issued at 1005 AM EDT Mon Jun 8 2026 VFR conditions will prevail at both island terminals through 12z Tuesday morning. With that said, passing showers and thunderstorms will be possible, particularly around the diurnally favored overnight periods. Confidence in timing and lack of coverage warrants leaving mention of VCSH out of the TAFs at this time. && .PRELIMINARY POINT TEMPS/POPS...
