DISCUSSION

Issued at 506 AM EDT Sun Jun 28 2026 Another summer night has come and gone in the Florida Keys. A majority of the night KBYX has been busy with scattered showers and thunderstorms popping up in different locations across our area. Though coverage has been widespread over the waters, the island chain has not gotten much measurable rainfall. Outside of these areas of convection, skies are mostly clear seen on Nighttime Microphysics. Temperatures across the islands are in the lower 80s slightly cooler than previous nights probably due to some showers cooling it off a bit. Along the Reef, marine observation sites are reporting easterly winds at near 10 knots.

Broad high pressure is still expected to be the main feature through early next week supporting the continuation of light to gentle east to southeasterly breezes. A frontal boundary is projected to move into northern Florida and into central Florida starting late Monday but it is not expected to have much impact on the local weather here other than slightly weakening the high and allowing for our breezes to slacken. Temperatures are expected to stay generally at near 90 with dewpoints in the mid 70s meaning the muggy conditions aren't going anywhere anytime soon. Stay hydrated.

MARINE

Issued at 506 AM EDT Sun Jun 28 2026 No watches, warnings, or advisories are currently in effect for the Florida Keys waters. From synopsis, a broad high pressure system centered over the North Atlantic will continue to extend westward to the Florida Peninsula through early next week. This will support bouts of light to gentle breezes that may freshen to gentle to moderate at times, mainly in the overnight hours. Starting late Monday, a frontal boundary will press south across the Florida Peninsula and stall across central Florida. This will act to weaken the high and allow for slackening breezes through Wednesday. Thereafter, a broad area of low pressure may develop along the residual stalled frontal boundary and move westward across Florida. This could potentially freshen breezes once again.

AVIATION

(06Z TAFS) Issued at 506 AM EDT Sun Jun 28 2026 VFR conditions will prevail at both EYW and MTH through the TAF period. Scattered showers continue to pop up in various locations therefore VCSH is included at both terminals through this morning. Near surface winds will be east to southeast at near 10 knots.
