242 FXUS62 KMFL 060807 AFDMFL Area Forecast Discussion National Weather Service Miami FL 407 AM EDT Thu Jun 6 2024 .SHORT TERM... (Today through Friday) Issued at 405 AM EDT Thu Jun 6 2024 Models depict a deepening trough across the E CONUS, with an embedded impulse of energy/shortwave pushing into the Florida peninsula today. Latest CAM/NBM and ensemble solutions insist in bringing this feature all the way down to SoFlo by this afternoon, which should be enhancing overall instability, and moderately increasing lapse rates and mid level moisture. The above synoptic scenario will combine with afternoon sea breeze circulations for shower and thunderstorm activity to develop. POP/Wx coverage will become scattered to numerous with 50-70% across interior and northern areas. Also, the steeper lapse rates and enhanced lifting with sea breezes and/or outflow boundaries may be enough for some cells to become strong or severe. Best overall chances remain over the northern half of SoFlo, but a strong thunderstorm could develop anywhere in the CWA today. Main hazards accompanying any storm that forms will be damaging gusty winds, frequent lightning, large hail and heavy rain. For Friday, the aforementioned deep trough continues migrating eastward, while an associated sfc frontal boundary pushes southward across the SE CONUS. This will begin veering winds across SoFlo to the S/SW and advect warmer air from the south. This will help in keeping the current trend of abnormally warm temperatures, with afternoon highs in the mid to upper 90s. Heat indices will likewise climb into the mid 100s for most areas, but isolated to scattered showers and thunderstorms could provide some relief wherever they form. && .LONG TERM... (Friday night through Wednesday) Issued at 305 AM EDT Thu Jun 6 2024 Over the weekend, the mid-level trough will advect eastward through the Florida Peninsula. An attendant surface frontal boundary will drift across the southeast US before stalling out, causing winds to shift to a west-southwest regime for the weekend, although winds will be generally light as a whole. The daily sea breezes and forcing for ascent from the trough will procide necessary energy for daily isolated to scattered showers and thunderstorms to develop. PoPs will be around 50-60% for most locations this weekend and convection should trend more towards the east coast compared to the west coast under light west-southwest flow. High temperatures could reach the mid to upper 90s each day, with areas in the interior potentially topping out in the triple digits. Heat indices will likewise climb into the mid 100s for most areas under southwest flow, and thus there will be potential for heat advisories. For early next week, guidance starts to vary more drastically. Overall, most guidance is hinting at the potential for a tropical disturbance to form in the Caribbean which would have the potential to impact the region at some point. However, with it being near the end of the forecast period, uncertainty is very high. Some solutions highlight potential for the disturbance to impact parts of South Florida while others show no impactful weather. Therefore, this potential system needs to be taken with a grain of salt for now, but if it continues to show signs of materializing in future guidance and has a chance to pose threats to South Florida, then potential impacts will be described. && .AVIATION... (06Z TAFS) Issued at 120 AM EDT Thu Jun 6 2024 VFR continues at all terminals through around 15Z, then another round of showers and/or thunderstorms may bring brief periods of sub-VFR cigs/vis. SE Winds increase to around 10kt this afternoon, then light and variable later in the evening. Only exception will be APF where a westerly flow develops with afternoon Gulf breezes. && .MARINE... Issued at 305 AM EDT Thu Jun 6 2024 Generally benign boating conditions should prevail across the coastal waters through the weekend, with winds in the 5-10kt range. Only exception will be in the vicinity of any thunderstorm that forms, which will bring brief periods of rough seas and gusty winds. Seas will remain in the 2 to 3 feet range in the Atlantic waters, and 2 feet or less in the Gulf waters. && .PRELIMINARY POINT TEMPS/POPS...
