KEY MESSAGES

- Breezy conditions will continue through the rest of the week, and into the start of the weekend. Across the Florida Straits, a Small Craft Advisory remains in effect. - The fast flow and modest moisture will result in a slight chance of showers over the next couple of days.

DISCUSSION

Issued at 1010 PM EDT Wed Apr 1 2026 An expansive area of high pressure stretching across Florida with a tight pressure gradient has kept weather conditions breezy, but mostly dry, through the evening shift as April Fools Day comes to an end. The sparse surface observations along the Keys have reported sustained winds of 15 to 20 mph with occasional gusts near 25 mph. Temperatures are in the mid to upper 70s with dew points in the mid to upper 60s. All together, while the breezy weather may be annoying, things don't feel too bad outside this evening.

Even without a notable lifting mechanism, the combination of modest moisture undulations and areas of some low level speed convergence have resulted in a line of light showers being picked up by our KBYX radar. These showers are moving westward at near 15 knots, or near 17 mph, and it's closest approach to the Keys will be just south of Key West sometime around midnight. Taking into consideration that the 00Z KKEY sounding from this evening sampled a reasonably moist lower level, and a few pockets of drier air aloft, so we can't rule out a few pop up showers during the overnight hours. Since showers have been supported through the evening, there isn't much of a reason to suggest that the forecast area will remain dry overnight.Carrying the inherited 10% PoPs seems reasonable for this evening update.

The only adjustment made to this evening update was extending the Small Craft Advisory until Thursday morning due to easterly winds remaining elevated. No other changes are needed at this time.

MARINE

Issued at 1010 PM EDT Wed Apr 1 2026 A Small Craft Advisory remains in effect for the Florida Straits due to easterly winds near 20 knots and seas up to 7 feet. Small Craft Should Exercise Caution across all other marine zones as moderate to fresh breezes will continue over the next few days.

AVIATION

(00Z TAFS) Issued at 1010 PM EDT Wed Apr 1 2026 VFR conditions will prevail at both terminals with SCT to occasionally BKN decks near FL030. Skies will clear up shortly after sunrise. Surface winds will remain easterly near 15 knots with infrequent gusts near 20 knots. There is a low chance of some light showers near either terminal, but opting to key TAFs dry for now until activity drifts closer.
