FXUS62 KKEY 261855 AFDKEY Area Forecast Discussion National Weather Service Key West FL 255 PM EDT Sun May 26 2019 .DISCUSSION... Deep-layer ridging rooted in Central America reaches northeast into the southeastern United States. Remarkably high mid-level heights persist over northern FL and southern GA/AL/MS. The surface anticyclone stretches west across northern Florida and supports fresh easterly breezes across the Florida Keys. Limited moisture, significant low-level inhibtion, and mainly anticyclonic low- level streamlines have precluded precipitation and cloud cover across the island chain. Temperatures are in the upper 80s with dewpoints near 70. .FORECAST... Very little change to the pattern and forecast reasoning tonight through Tuesday. Deep-layer ridging will persist, although a subtle southwesterly displacement of the mid-level heights towards the northern Gulf of Mexico is expected. Moisture channel imagery highlights an anticyclonic wave break and a weakness in the overall ridging over Cuba and the Western Caribbean, co- located with vorticity maxima at all the CIMMS analysis levels. This feature will erode by Tuesday night, allowing the subtropical ridge to build southward across Hispaniola and Cuba. This will open-up the low- level tap to deepening tropical moisture and a return to mid 70s surface dewpoints. And yet, mid- level subsidence and dry air will battle the decreasing static stability associated with the warming and moistening of the low levels. We highlight nearly nil rain chances tonight through Tuesday, followed by near normal (10-25%) slight rain chances through the remainder of the forecast period. Through-it-all, moderate to fresh, east to southeasterly breezes will peak and lull. Overnight lows will trend slightly higher as surface winds take-on a more southeasterly fetch. The inherited seven-day forecast is on track and needs no adjustments. && .MARINE... High pressure centered just to the west of Bermuda supports fresh easterly breezes across the coastal waters of the Florida Keys. Although this system will settle southward over the next few days, periods of moderate to fresh, east to southeasterly breezes will be maintained through the forecast period. && .AVIATION... VFR and gusty easterly breezes will prevail at the EYW and MTH terminals through the evening. && .PRELIMINARY POINT TEMPS/POPS...
