KEY MESSAGES

- Light to gentle southwest to west breezes expected overnight, occasionally variable.

- Only a slight chance (10% to 20%) of rain and thunder will be in place for the next few days. - While highs will be seasonably warm in the upper 80s through next week, lows will remain warmer than normal, providing little relief from the heat in the overnight hours.

SHORT TERM FORECAST

The 00z evening sounding shows an unstable profile with moist layers between 950 to 900 mb and around 500 to 450 mb. There is fairly stout dry air between the moist layers with more dry air above 450 mb. The wind profile is chaotic and indicative of more of a daytime cloud line regime rather that nighttime activity. Instability is also decent between 1300-1800 J/kg. Also, the PWAT value measured was 2.17 inches which is above the 90th percentile for the date. Outside of any residual boundaries throughout the Keys, expecting a fairly quiet night. However, with the mainly southwest to west flow and plenty of moisture across the region, a few showers may develop from time to time along these remnant boundaries. Therefore, no changes to the ongoing forecast.

MARINE

Issued at 1030 PM EDT Fri May 29 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 southeast to south breezes over the next few days, becoming light and variable at times. The nebulous pressure pattern will continue through much of early next week, with 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 wind speeds as well as rain chances.

AVIATION

(00Z TAFS) Issued at 1030 PM EDT Fri May 29 2026 VFR conditions are mostly expected at both EYW and MTH terminals through the TAF period. However, there remains the possibility of for a few periods of MVFR CIGs through the period, especially during the daylight hours on Saturday. There is the potential for another cloud line during the day. Therefore, a shower or two is possible, mainly during the daytime Saturday. Otherwise, expect mainly light southwest to west breezes, occasionally variable.
