870 FXUS62 KKEY 161554 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1054 AM EST Sun Nov 16 2025 ...New DISCUSSION, MARINE, AVIATION... .KEY MESSAGES... -Light to gentle breezes will continue through into early week, variable at times. -Dry air will limit shower development through early this week. -High temperatures will warm to near 80F for much of the work week. && .DISCUSSION... Issued at 1044 AM EST Sun Nov 16 2025 After a pronounced radiational cooling event overnight, with temperatures dropping into the lower 60s across the Island Chain, ample sunshine is allowing temperatures to quickly rebound into the mid 70s at this mid-morning Sunday hour. The 12z morning sounding at KEY sampled a strong temperature inversion based roughly at the 850 mb isobaric surface, with substantial dry air throughout the rest of the troposphere above. Visible satellite imagery is struggling to detect even scattered cloud cover across the Florida Keys and the adjacent nearshore and offshore coastal waters. A stagnant, dry, and seasonally warm pattern continues to transpire. No changes to the inherited mundane forecast required. && .MARINE... Issued at 1044 AM EST Sun Nov 16 2025 There are currently no watches, warnings, or advisories in effect across the Florida Keys coastal waters. From synopsis, weak high pressure will continue to promote light to gentle breezes today through Monday. Due to the weak flow, there may be periods of light and variable breezes, mainly in the afternoons. Another high pressure system will traverse across the eastern United States early this week while slowly strengthening. This will allow for freshening northeast to east breezes for the middle and latter part of the week. && .AVIATION... (15Z TAFS) Issued at 1044 AM EST Sun Nov 16 2025 VFR conditions will prevail at both EYW and MTH through the TAF period. Dry air will limit any shower development and cloud coverage will be minimal. Light breezes will generally be northerly, occasionally variable, especially during the afternoon hours && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
