KEY MESSAGES

- Rain chances will be near zero for the island chain through most of, if not the rest of, the week.

- Light and variable winds will gradually veer to the east to southeast by Wednesday morning.

- Dew points may increase to the mid 70s by the end of the week, and this will bring about some heat risk concerns as these will be the first prevailing higher dew points of the season.

SHORT TERM FORECAST

The 00z evening sounding is much drier tonight compared to 24 hours ago. Some moisture remains in a shallow layer between 975-925 mb with another shallow moist layer between 250-200 mb. The PWAT value measured was 1.04 inches which is substantially drier than last evening. Based on the variable wind flow, lower moisture, and no source of lift, the forecast for tonight remains dry and unchanged.

MARINE

Issued at 1025 PM EDT Tue May 5 2026 There are currently no watches, warnings, or advisories in effect across the Florida Keys coastal waters. From synopsis, a poorly defined wind field with light and variable breezes will persist until ridging can become better established across the Florida peninsula on Wednesday. At that point, winds will become a climatologically appropriate light to gentle east to southeasterly breeze. Deep layered ridging will dominate from mid week through the remainder of the work week. This along with very weak forcing will keep rain chances out until at least Saturday when southeasterly breezes strengthen to gentle to moderate, bringing in increased boundary layer moisture and opening the door to maritime showers.

AVIATION

(00Z TAFS) Issued at 1025 PM EDT Tue May 5 2026 VFR conditions are expected to persist at both EYW and MTH terminals through the TAF period. Near surface winds will remain northwest to north through the wii hours of the overnight before shifting to the southeast.
