394 FXUS62 KKEY 090834 AFDKEY Area Forecast Discussion National Weather Service Key West FL 434 AM EDT Sun Jun 9 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 430 AM EDT Sun Jun 9 2024 A stretch of showers with the occasional lightning strike are still working their way northward through the Florida Keys and surrounding waters this very early morning. Today will look similar to yesterday where there is plenty of sunshine available during the morning and afternoon, but some showers and thunderstorms will find their home over the surrounding waters in the later afternoon and evening hours later today. Highs today will be near 90, and dewpoints in the upper 70s will lead to heat indices just barely passing the 100-degree mark during peak heating. While this does sound like a typical Florida day in the summer, it still looks like this will be the only day that looks like this for the rest of the forecast period. Confidence remains elevated that we are entering an extended period of wetter weather. A developing Central American Gyre will help to push moisture into the region, and the unstable environment will set us up for a mix of showers and thunderstorms through the rest of the week. As the forecast stands, the wettest days with the greatest areal coverage are still expected to be Tuesday through Thursday, but that`s not to take away from the possibility of activity on Monday and the end of the week. There is still some question as to just how much rainfall we will see, but the overall picture of a wet and soggy week ahead remains. && .MARINE... Issued at 430 AM EDT Sun Jun 9 2024 There are currently no watches, warnings, or advisories in effect across the Florida Keys. From synopsis, the pattern will feature weak high pressure over the western North Atlantic and a frontal boundary stalled over northern Florida. This will result in light to gentle southerly breezes across the Keys coastal waters today through Monday. Freshening breezes and an extended period of unsettled weather may begin as early as Tuesday and will persist through Thursday night. && .AVIATION... (06Z TAFS) Issued at 430 AM EDT Sun Jun 9 2024 VFR conditions continue to prevail at EYW and MTH for the upcoming TAF period. Nocturnal showers are lingering south of the island terminals, close enough to EYW to warrant a TEMPO group, and are forecast to wane by sunrise. Dry conditions aloft are expected to keep shower coverage low after sunrise which resulted in the absence of VCSH in the TAFs, but possible showers and MVFR conditions are possible. Near-surface winds will gradually shift from south- southwesterly to south-southeasterly at 5 to 10 knots. && .CLIMATE... On this day in Keys weather history, in 1997 the daily record rainfall of 3.18" was measured at Key West. Rainfall records for Key West date back to 1871. && .PRELIMINARY POINT TEMPS/POPS...
