KEY MESSAGES
- A Small Craft Advisory remains in effect for all Florida Keys coastal waters overnight. Breezy conditions will persist through at least early Wednesday morning. - Little to no measurable rain will maintain continued moderate drought conditions in the Florida Keys for the next week.
- Temperatures will remain near normal, with highs in the lower 80s, and lows in the lower 70s.
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 850 mb. The sounding also shows general unidirectional wind flow with height. The sounding measured a PWAT value of 0.73 inches which is below the 10th percentile for the date. This is indicative of a very dry atmosphere. The only catalyst for a shower would speed convergence overnight due to the increased wind flow. The best chance for seeing a shower would be across the Straits of Florida where the slightly deeper moisture is present.
MARINE
Issued at 1000 PM EDT Tue Apr 14 2026 A Small Craft Advisory remains in effect for all the Florida Keys coastal waters overnight. From synopsis, a high pressure system over the central North Atlantic will maintain moderate to fresh northeast to east breezes (except fresh to strong Florida Straits) overnight through Wednesday night. Occasional fast- moving light showers cannot be ruled out, especially in the overnight periods. Breezes likely will lull from late morning into the late afternoon across the Gulf waters due to the heating of South Florida. As the high moves farther eastward and slowly weakens, easterly breezes will slacken Thursday through Sunday.
AVIATION
(00Z TAFS) Issued at 1000 PM EDT Tue Apr 14 2026 VFR conditions are expected to persist at both EYW and MTH terminals through the TAF period. Near surface winds will remain mainly easterly between 10 to 15 knots with frequent gusts to near 20 knots, especially during the daylight hours Wednesday.
