SHORT TERM FORECAST
The 00z evening sounding at KEY sampled a very dry atmospheric profile throughout the entire column with a stout inversion just above 875 mb. The sounding also shows general unidirectional wind flow with height. The sounding measured a PWAT value of 0.72 inches which is below the 10th percentile for the date. The dry atmosphere remains across the Keys for overnight. Rain chances have been removed from the forecast for the overnight as a result of the vast dry air in place across the area.
MARINE
Issued at 1000 PM EDT Wed Apr 15 2026 There are currently no watches, warnings, or advisories in effect across the Florida Keys coastal waters. From synopsis, high pressure over the central North Atlantic will maintain gentle to moderate northeast to east breezes through the next several forecast periods. Breezes likely will lull from late morning into the late afternoon across the Gulf/Bayside waters due to the heating of South Florida. As the high moves farther eastward and slowly weakens, easterly breezes will slacken Thursday through Sunday. A new high pressure will slide eastward Sunday night into Monday, allowing for another round of freshening breezes.
AVIATION
(00Z TAFS) Issued at 1000 PM EDT Wed Apr 15 2026 VFR conditions are expected to persist at both EYW and MTH terminals through the TAF period. Dry air will continue to dominate the Keys with nil rain chances a result. Near surface winds will remain mainly easterly between 7 to 12 knots.
