DISCUSSION

Issued at 929 PM EDT Wed Apr 29 2026 High pressure is still dominating our sensible weather across the area, though it has been difficult to pinpoint where the heart of it may be. A tell tale sign of this high is how calm our weather conditions are across the forecast area. Breezes are light and variable with the only semblance of directional uniformity currently occurring along marine platforms along Hawk Channel where surface winds are out of the southeast. Satellite imagery only shows a few low to mid level clouds over Florida Bay. Otherwise, skies are essentially clear. Based on the 00Z KKEY sounding from this evening, there may be a few very low clouds that are too low for the nighttime satellite derived products to detect, but looking at the automated observations at both Key West and Marathon International Airports currently shows multiple reports of clear skies. The sounding also offers insight as to why our KBYX radar is void of meteorological returns. Even though PWAT was calculated to be 1.11", the wind profile showed a backing trend, and there was a notable inversion between 830mb and 780mb. All of this considered, the inherited forecast is standing on its own just fine. No changes or updates are needed to the inherited package.

MARINE

Issued at 929 PM EDT Wed Apr 29 2026 There are no watches, warnings, or advisories in effect for the Florida Keys local waters. An area of high pressure will continue to encourage light to gentle southeasterly breezes, though direction may become variable at times over the next couple of days. Breezes will modestly freshen while resuming a uniform southeasterly direction by late Friday. Rain and thunderstorm chances will return for the weekend, and will linger into the start of next week.

AVIATION

(00Z TAFS) Issued at 929 PM EDT Wed Apr 29 2026 VFR conditions will prevail at both island terminals with southeasterly surface winds near 5 knots becoming variable at times. Rain and thunder chances through this TAF package are near zero, so there are no concerns with respect to inclement flight conditions at either terminal.
