AVIATION

(18Z TAFS) Issued at 134 PM EDT Tue Jun 23 2026 Conditions will remain dry across the TAFs through at least 06z this evening. Increasing low-level moisture may spark a few showers or isolated thunderstorms thereafter through 18z Wednesday afternoon. However, the lack of coverage and impacts to visibilities as well as ceilings warrants keeping mention out of the deterministic TAFs. Near- surface winds out of the southeast will slowly back to the east to southeast overnight.

PREV DISCUSSION

Issued at 428 AM EDT Tue Jun 23 2026 As the SAL exits stage left tonight, somewhat better moisture will return. That being said, rain chances will continue to unimpressive at 10 percent or less. Rain chances may tick up slightly as a weak easterly undulation pivots up from the Caribbean Friday night through Saturday evening. Another easterly undulation arrives from near the Bahamas Monday into Tuesday with the potential for better moisture and therefore accumulating rains.

Otherwise, temperatures will remain rather stagnant with day time highs near 90 degrees and overnight lows in the lower to mid 80s. Muggy conditions will persist with daily heat indices reaching or exceeding 105 degrees.

MARINE

Issued at 1035 AM EDT Tue Jun 23 2026 Any residual showers and thunderstorms in the southeastern Gulf will continue to dissipate over the next couple of hours. From synopsis, a broad, weak high pressure system stretching from the Gulf Basin, across the Florida Peninsula, and into the central North Atlantic will fluctuate in strength over the next several days. As a result, expect both wind speeds and direction to be primarily mesoscale driven and at times chaotic. By Wednesday night, the high will begin to gradually build and allow for a slow freshening of east to southeast breezes.
