KEY MESSAGES

- Conditions will be marginally conducive for a cloud line through the remainder of the day. - Light and variable winds will persist into the first part of the weekend.

- A more active weather pattern develops by early next week with higher rain chances and increasing southeasterly winds.

AVIATION

(18Z TAFS) Issued at 133 PM EDT Fri Jul 31 2026 VFR conditions with light/VRB winds are expected throughout the period as high pressure remains in control across the region. In addition, a cloud line has formed across the Island Chain but it is lacking any meaningful organization. As a result, any shower activity associated with this feature is expected to be light enough to keep any aviation concerns minimal at this time, though brief MVFR restrictions can't be completely ruled out through the remainder of the day if the CIGs associated with the cloud line lower enough.

PREV DISCUSSION

Issued at 512 AM EDT Fri Jul 31 2026 Last night's KKEY 00z sounding revealed a drier profile explaining the lack of showers experienced overnight. Across the island chain temperatures are in the mid to lower 80s with dewpoints in the mid 70s. Cloud coverage seen on Nighttime Microphysics is mostly clear for the Lower Keys while the Upper Keys have some upper level clouds drifting through. Along the Reef, marine locations are reporting mostly light and variable winds. For today, with these light and variable winds cloud line development is possible similarly to yesterday with possible waterspouts associated with that. Outside of showers produced from the cloud lines, limited shower development is expected for the day. This pattern is expected to last for the next few periods. As a trough moves easterly on Sunday, winds are expected to freshen and become southeast to east once again. This trough will also reignite the moisture resulting in higher rain chances for later in the week. Stay tuned.
