KEY MESSAGES

- Mainly light to gentle variable breezes are expected to persist throughout the Florida Keys coastal waters overnight. - While highs will be seasonably warm in the upper 80s through at least mid week, lows will remain warmer than normal, providing little relief from the heat in the overnight hours.

- Increasing moisture mid to late week will result in above normal rain and thunder chances.

SHORT TERM FORECAST

The 00z evening sounding remains unstable, though, not nearly as unstable as last night. The PWAT value measured was 2.28 inches which is once again a new record for the date since the previous max was 2.24 inches. The wind profile shows north to northeast breezes which isn't all that conducive for showers. However, latest radar shows multiple boundaries across the area once again tonight. Therefore, due to potential boundary collisions and some convergence overnight, there is the risk for more pop up showers with the potential for a stray thunderstorm. Most of the energy was used up during the day and this evening lending to mostly showers anticipated rather than thunderstorms. No changes expected to the ongoing forecast as a result

MARINE

Issued at 1030 PM EDT Mon Jun 1 2026 There are currently no watches, warnings, or advisories in effect across the Florida Keys coastal waters. From synopsis, weak high pressure across the area will support light to gentle breezes going back and forth between southwest to northwest over the next couple of days. Near normal rain and thunder chances also expected. A weak frontal boundary may stall near the Keys coastal waters by mid week, supporting an uptick in breezes as well as rain chances.

AVIATION

(00Z TAFS) Issued at 1030 PM EDT Mon Jun 1 2026 VFR conditions are expected to continue at both EYW and MTH terminals through the TAF period. Near surface winds will remain mostly northwest to north, occasionally becoming variable, especially overnight into Tuesday morning. Slight chance for showers and thunderstorms remain in the forecast. However, due to the timing and placement being uncertain, VCSH was not included in the TAF.
