023 FXUS62 KKEY 060158 AFDKEY Area Forecast Discussion National Weather Service Key West FL 958 PM EDT Wed Jun 5 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1000 PM EDT Wed Jun 5 2024 Almost a carbon-copy evening compared to yesterday`s for the Florida Keys. A broken cloud line sputtered along and west of the Lower Keys, with all associated shower activity remaining offshore of the island chain. The line quickly fell apart thereafter, likely owed to the sampled nose of dry air between 950-875 mb in the evening`s 00z sounding at KEY. GOES-16 satellite nighttime microphysics imagery is detecting mostly clear skies across the Keys and the adjacent coastal waters, with KBYX void of meteorological echo returns across the entire CWA. For the overnight period, the aforementioned dry air should keep most island communities dry. However, there are still a few ghost boundaries likely roaming across the coastal waters. Should they interact, given the relatively uncapped environment owed to very weak mid- level ridging, isolated brief showers cannot be ruled out. Temperatures will generally only dip into the lower 80s for the overnight period, although should winds collapse a bit more than expected, a few upper 70s to near 80F readings cannot be ruled out in the favored larger island communities. No changes proposed for tonight`s evening forecast update cycle. && .MARINE... Issued at 1000 PM EDT Wed Jun 5 2024 No watches, warnings, or advisories are in effect for Florida Keys coastal waters zones. A weak area of high pressure centered southwest of Bermuda will slowly slide eastward in the North Atlantic, resulting in light to gentle east to southeast breezes through Thursday night. Winds may freshen out of the south late this weekend into early next week, as pressures fall in the northwestern Caribbean Sea. && .AVIATION... (00Z TAFS) Issued at 1000 PM EDT Wed Jun 5 2024 VFR conditions will prevail at both island terminals through the TAF period. Any potential rain and thunder coverage in the vicinity of the terminals will continue be limited to any residual boundary collisions overnight, but chances are too low to include mention in the TAFs at this time. Near-surface winds will remain out of the east to southeast at 8 to 10 knots. && .CLIMATE... On this day in 1985, Key West measured a record high temperature of 93F. On the same day, Marathon measured a record high temperature of 96F. Temperature records for Key West and Marathon date back to 1872 and 1950, respectively. && .PRELIMINARY POINT TEMPS/POPS...
