Area Forecast Discussion National Weather Service Key West FL 1041 PM EDT Mon Jun 8 2026
New DISCUSSION, MARINE, AVIATION
KEY MESSAGES
- Near normal rain and thunder chances through Tuesday night.
- Light to gentle east to southeasterly breezes will continue for the next few days.
- Bouts of increased rain and thunder chances are possible Wednesday through next weekend.
DISCUSSION
Issued at 1040 PM EDT Mon Jun 8 2026 Scattered showers continue to be detected on KBYX as they have been for a majority of the evening. While many have tried to become stronger, these showers have been limited by dry air aloft seen on KKEY 00z sounding from tonight. Temperatures across the island chain are currently in the mid 80s with dew points in the mid 70s making for another regular Summer night. Along the Reef, observation sites are recording 10 to 15 knots and are east to southeasterly. As surface high pressure continues to sit east of Bermuda our conditions are expected to stay similar in the overnight period, therefore no changes were made to the current forecast package.
MARINE
Issued at 1040 PM EDT Mon Jun 8 2026 No watches, warnings, or advisories are currently in effect for the Florida Keys waters. From synopsis, a surface high pressure system centered east of Bermuda will support light to gentle east to southeast breezes across the Florida Keys coastal waters through mid- week. A second high pressure system will push into the western North Atlantic by mid- week, maintaining light east to southeast breezes. Rain and thunder chances will be at near- normal levels early in the week, with a potential increase in coverage beyond Tuesday.
AVIATION
(00Z TAFS)
Issued at 1040 PM EDT Mon Jun 8 2026 VFR conditions will prevail at both EYW and MTH through the TAF period. Light showers are possible overnight at either terminal but confidence on likelihood and exact location leaves mention of VCSH out of the TAFs for the time being. Near surface winds will be east to southeasterly at 10 to 15 knots.
