KEY MESSAGES

- Very warm and humid conditions over the next few days will lead to bouts of major risk of heat illness in the afternoon hours, with little relief during the overnight periods. - Quick moving showers and storms may bring bursts of heavy rainfall, reduced visibility, and gusty winds through the weekend.

- Confidence continues to increase for a potentially wet and thundery period through the middle to latter part of next week.

AVIATION

(18Z TAFS) Issued at 123 PM EDT Sat May 23 2026 Although VFR conditions will prevail at both island terminals through the TAF period, passing showers or thunderstorms are certainly possible, mainly in the late overnight hours tonight. Keeping VCSH out of the forecast for now due to the limited coverage and lack of confidence in timing, as well as minimal reductions in visibilities and ceilings.

PREV DISCUSSION

Issued at 533 AM EDT Sat May 23 2026 High pressure will continue to dominate our pattern with winds slackening in the late morning hours and re- freshening in the overnight periods. Showers will continue to pop up occasionally in different locations but not expecting it to be an all day soaker in any given spot.

A similar pattern is expected through early next week with upper level ridging and surface high promoting east to southeasterly breezes with a chance of showers and slight chance of thunderstorms. As the week progresses, the ridge will move southeasterly resulting in the wind direction veering more southeast to south and allowing for an increase in tropical moisture. Around Tuesday night rain chances will become elevated for a few periods before returning to seasonal norm on Thursday. Temperatures will continue to be in the upper 80s during the day and not much relief with the lows in the lower 80s for the majority of the upcoming week.

MARINE

Issued at 1025 AM EDT Sat May 23 2026 There are no watches, warnings, or advisories for the Florida Keys marine zones. From synopsis, high pressure remains parked east of Bermuda. The surface pattern will remain generally unchanged for the next few days, with breezes peaking to near fresh in the evening and overnight hours, slackening to gentle to moderate in the late morning and afternoon hours. A second high pressure system will reinforce the first, supporting fresh east to southeast breezes late in the weekend into early next week.
