DISCUSSION
Issued at 1040 PM EDT Sun Apr 26 2026
A very weak cloud line developed late in the afternoon across mostly the Lower Keys, though a smaller version tried to form across the Middle Keys. The line over the Lower Keys, made an attempt to produce some isolated showers, however, looking at surface obs it doesn't appear we saw any accumulations. Meanwhile, temperatures and dew points are slightly higher than last night. Currently seeing temperatures in the upper 70s to lower 80s with dew points in the lower 70s.
Winds are a hair bit stronger than previously though as a very, very weak nocturnal response is coming down the west coast of Florida. Generally seeing speeds near 10 knots from the northwest at all marine observation platforms.
Tonight's sounding shows that drier air has returned to the lower levels. This lines up with what models were depicting with the northwest flow pushing the moisture offshore. Therefore, if we do manage to see any showers, they will be limited to the eastern Straits of Florida. Otherwise, saw no need to make major changes to the forecast.
MARINE
Issued at 1040 PM EDT Sun Apr 26 2026
Gentle northwest breezes have developed this evening and will gradually slacken to light to gentle late overnight and into early Monday morning. As a high pressure slowly pushes further east across the North Atlantic, we will go into a col region with light and variable winds shortly after sunrise Monday. A high moving along and just off the Eastern Seaboard will briefly freshen breezes Monday night through Tuesday evening before slackening once again.
