Issued at 1037 PM EDT Sun Jun 30 2024 After an active weather day, the radar has gotten eerily quiet during the evening hours. This should be temporary and another round will likely develop overnight and continue into the morning hours on Monday. This is because there is an inverted trough moving through the easterlies which is providing us the moisture and lift needed for convection. This hour, looking at infrared satellite imagery coupled with KBYX/KAMX radars, it appears the trough axis is roughly located between Andros Island and South Florida. This feature has been making very slow progress to the west. Given that most of the convection ended fairly early in the evening period there is plenty of time for the atmosphere to recharge. Especially as we begin to enter the peak nocturnal diurnal. The trough axis will continue to slowly push west overnight and expecting another round to develop. As such, even though we are in lull, will keep PoPs at high end chance for now. This is also supported by several hi-res CAMs. As this trough pushes across the area, we will see northeast to east winds become more east to southeast towards dawn. && .MARINE... Issued at 1037 PM EDT Sun Jun 30 2024 No watches, warnings, or advisories are currently in effect. We are currently in a lull for convection but expecting another round is expected to develop late overnight and continue into the morning hours on Monday. Mariners and boaters should expect winds and seas higher in and around any thunderstorms that develop. Northeast to east winds will shift around to the east and southeast as an easterly undulation passes through the area early Monday. Tropical Depression 3 located in the southwestern part of the Bay of Campeche will move inland overnight and dissipates. The western periphery of the subtropical high over the Atlantic will maintain modest control over the Keys. This will result in mainly gentle to moderate breezes over the next few days, occasionally light to gentle. Tuesday through late week, breezes will freshen as the gradient between the subtropical high over the Atlantic and Beryl (major hurricane) strengthens. Beryl is expected to remain well south of the Florida Keys as it marches west northwest through the Caribbean Sea. Please review the Tropical Cyclone Advisories for additional information on the track and future evolution of Beryl. && .AVIATION... (00Z TAFS) Issued at 1037 PM EDT Sun Jun 30 2024 VFR conditions will prevail for now as we are in a lull in the convection. Expecting another round to develop after 06Z/1st and continuing well into the morning hours. Given the lower confidence on exact placement of these showers and storms and where the strongest cells may pass over, have kept out mentions of MVFR or even sub IFR conditions for now. However, they do remain at least a possibility at this time. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
