(18Z TAFS) Issued at 302 PM EDT Sat Jul 12 2025 Although a passing shower or storm cannot be ruled out in the vicinity of the terminals, VFR conditions will prevail. Near- surface winds will remain out of the east to southeast at 8 to 10 knots. && .MARINE... Issued at 302 PM EDT Sat Jul 12 2025 No watches, warnings, or advisories are currently in effect in the Florida Keys waters. From synopsis, sprawling high pressure in the North Atlantic will support light to gentle east to southeast breezes through early next week. Near- normal rain and thunder chances are expected through the weekend. A disturbance off the Southeast is expected to dive southwestward towards the Florida Peninsula for early next week, supporting bouts of increased storm chances. && .PREV DISCUSSION... Issued at 302 AM EDT Sat Jul 12 2025 A band of deep convection progressed through the offshore Gulf waters and also in the vicinity of the Middle Keys earlier this morning. These storms quickly waned, likely owed to an ingestion of mid-level dry air. KBYX Doppler radar is now only detecting a few isolated showers throughout the Florida Keys coastal waters. Ample sunshine has allowed temperatures to quickly rise into the upper 80s. While it is tempting to lower rain chances for the balance of today, localized confluence, coupled with existing ghost boundaries, suggests scattered coverage may redevelop later this afternoon. No changes proposed for this late morning forecast edition. && .FORECAST... Issued at 505 AM EDT Sat Jul 12 2025 This weekend the high pressure that has been dominating our weather will persist maintaining east to southeasterly flow which will be slightly elevated due to the tightening of the pressure graident. Shower activity will be abundant throughout today but as dry air, due to Saharan dust, moves east into our area, chances will decrease for the remainder of the weekend. Early next week, a shift in the pattern is expected. Mid- level ridging is projected to shift northward as another tropical wave moves in from the east. At this time PoPs remain at a chance but as forecast certainty improves, updates could be necessary. && .PRELIMINARY POINT TEMPS/POPS...
