Area Forecast Discussion National Weather Service Key West FL 250 PM EDT Mon Jun 24 2024

New DISCUSSION, MARINE, AVIATION

DISCUSSION
Issued at 250 PM EDT Mon Jun 24 2024

Radar has become more active over the last couple of hours as even more tropical moisture moves into our area. Although showers are widespread any thunderstorms have struggled which could be due to the warmer temperatures aloft as revealed in this morning's 12z sounding. Surface winds across the reef are around 5 knots. For this evening, shower activity will continue into tomorrow before starting to trail off tomorrow afternoon into tomorrow evening.

As the trough that has been the main driver of our active weather retreats east and away from Florida over the next day, our winds will in result shift to the west southwest. With still plenty of moisture in our area and the WSW wind direction, cloudlines could develop over the next few days impacting the island chains.
Thereafter, towards the end of the week the ridge will move northward and we will return to our more typical summer pattern with east to southeast flow and near normal PoPs of around 30%. No chances are necessary to the current forecast at this time.

MARINE
Issued at 250 PM EDT Mon Jun 24 2024

There are no watches, warnings, or advisories in effect for the Florida Keys coastal waters. From synopsis,high pressure over the western Atlantic and low pressure over the Bay of Campeche will maintain gentle east to southeast breezes through tonight. The western Atlantic ridge will settle southward into the Florida Straits from Tuesday through Thursday, with light southwest to west breezes prevailing over the Keys waters. The ridge will shift back northward late this week, allowing light to gentle southeast breezes to resume.

AVIATION
(15Z TAFS)
Issued at 250 PM EDT Mon Jun 24 2024

Scattered showers and thunderstorms will continue to blossom over the next several hours in the vicinity of the terminals, lasting through much of the evening. Due to the spotty and chaotic nature of these storms, a general VCSH is mentioned for now, with additional TAF amendments including TEMPOs to account for more specific impacts to sub-VFR VIS and CIGs likely required. Outside of convection, near surface winds will be from the east to southeast at 4 to 7 knots, veering to the south to southwest after 06z tonight.

KEY WATCHES/WARNINGS/ADVISORIES
FL...None.
GM...None.
