| Area Forecast Discussion National Weather Service Key West FL 426am EDT Thu Jun 18 2026 Issued at 426am EDT Thu Jun 18 2026 Another sultry overnight for the Florida Keys as temperatures as of 4am remain in the mid 80s with dew points in the upper 70s. This is resulting in widespread heat index values in the mid 90s currently. Prior to midnight we tied a new warm low temperatures and we are on track to do it again. Meanwhile, KBYX radar is quiet, though we are tracking some land breeze boundaries coming off both Cuba and Andros Island that are tracking northwest towards our waters. These boundaries may be enough of a trigger for a few isolated showers or even a brief thunderstorm this morning as they pass over the Middle and Upper Keys. Expanding our scope of vision, we have a deep layer ridge centered across the west central Atlantic that extends westward into the Gulf Basin. Round the the southwestern periphery of this ridge is a weak TUTT located over east central Cuba. There's not much of a surface reflection this hour and likely will not develop one as it is expected to weaken as it pivots towards the Florida Keys later today and into this evening. That being said, the presence of the TUTT and the remnants of Arthur will act to weaken the western edge of the ridge and bifurcate the ridge. This will leave a smaller, secondary ridge orphaned across the Gulf Basin, which will lead to a weakening pressure field and subsequent wind pattern for the Florida Keys. In fact, we could see a brief period of light and variable winds, especially Sunday into Monday. At the same time, we will continue to see meager moisture above the boundary layer through the next several days, resulting in PoPs of 10 percent or less. In addition, we will continue to see daytime highs near 90 degrees with overnight lows in the mid 80s and dewpoints holding in the mid to upper 70s. The combination will elevated our heat risk, especially today and Friday in the Upper Keys. Here we could see heat index values approaching 108 degrees briefly in the afternoon. Marine Issued at 426am EDT Thu Jun 18 2026 An ongoing nocturnal surge with gentle to moderate breezes will slowly slacken through the morning and afternoon. Expecting breezes to slightly surge again tonight before a ridge across the Atlantic and Gulf Basins weakens. Light to gentle breezes will return by Friday night and continue through the upcoming weekend. Waters north of the island chain will likely see periods of light and variable winds this weekend. Thereafter, the ridge will gradually re-strengthen and allow for breezes to slowly freshen next week. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None. GM...None. |
