KEY MESSAGES

- Mainly light to gentle and often variable breezes are expected to persist throughout the Florida Keys coastal waters over the next couple of days.

- Rain and thunder chances will trend upwards over the next couple of days, peaking around Wednesday. - After slightly above normal temperatures today, temperatures should trend downwards to near normal.

AVIATION

(15Z TAFS) Issued at 135 PM EDT Tue Jun 2 2026 VFR conditions will prevail at EYW and MTH for the upcoming TAF period. Cloud line activity in the afternoon will keep VCSH nearby at MTH and south of the island chain. Expect occasional TSRA and gusty winds near cloud lines.

PREV DISCUSSION

Issued at 437 AM EDT Tue Jun 2 2026 Through the remainder of the week, rain and thunder chances will trend upwards to well above normal. This is due to the swath of deep moisture remaining across our area and a frontal boundary steadily pushing southward towards the Keys. Rain chances will likely peak mid week as the boundary reaches South Florida and the Keys and the tail end of the lower level trough scraps by our area. In addition, some upper level diffluence may be present at the same time, further supporting convective activity. The combination of increased cloud cover and convective activity should keep temperatures near normal.

Heading into the weekend, the surface boundary will likely push past the Keys as robust high pressure builds across the eastern United States and surface troughing lifts out along the Atlantic Coast. Dew points and rain chances should trend downwards, but how far depends how far the surface high is able to press across our area. Adding to the uncertainty will be deep layered moisture remaining quite high and possible upper level troughing moving into Florida.

MARINE

Issued at 437 AM EDT Tue Jun 2 2026

No watches, warnings, or advisories are in effect for the Florida Keys coastal waters. A surface low will migrate eastward off of the southeast Atlantic coast over the next few days. This will keep a weak and narrow surface ridge across the Bahamas and the Keys, resulting in light and variable breezes on Keys waters. Expect well above normal shower chances with isolated to scattered thunderstorms due to considerable deep moisture. From mid week and beyond, broad high pressure will build eastward off of the eastern United States and bring about modest freshening northeast to easterly breezes and rain chances slipping back to seasonal norms by the weekend.
