505 FXUS62 KMFL 301853 AFDMFL Area Forecast Discussion National Weather Service Miami FL 253 PM EDT Thu May 30 2024 ...New LONG TERM... .SHORT TERM... (This afternoon through Friday) Issued at 1127 AM EDT Thu May 30 2024 A subtle upper troughing pattern will remains present across southeastern CONUS, including South Florida. The east-northeasterly winds continue to prevail across the region. As a result, the convergence of low-level moisture, due to ENE winds and the Gulf sea breeze, will lead to the majority of convective activity occurring over the interior and southwest Florida. While the 12Z morning sounding did not have favorable lapse rates (<6.0 J/kg), models indicate steepening lapse rates this afternoon, as well as CAPE values (1500 J/kg+). Therefore, we cannot rule out a few strong thunderstorms, particularly from the early afternoon through late evening hours. Tomorrow, there will be a weakening of the upper flow and the eastward exit of the upper level shortwave into the western Atlantic waters. The best chance for showers and thunderstorms will occur further westward in the SW coastal and interior regions. Despite weaker activity than previously this week, the storms will still bringing potential impacts including strong wind gusts, frequent lightning, and localized flooding. For the remainder of the week, the afternoon high temperatures will remain in the upper 80s to low 90s, with the highest temperatures expected across the western portions of the region. The eastern metro will remain above heat advisory criteria, with apparent temperatures not expected to rise above 100-102 degrees. && .LONG TERM...

(Friday night through next Wednesday) Issued at 253 PM EDT Thu May 30 2024 A welcomed change in the weather pattern is to be expected across much of South Florida this upcoming weekend, owing to a backdoor cold front across the western Atlantic waters. This will maintain the prevalence of east-northeasterly winds, which will result in a milder breeze coming in from the Atlantic waters across eastern portions of our CWFA. Expect a few quick-moving low-topped showers across the east coast at times, with the bulk of convection spawning yet again over the interior and southwestern portions of the region. A generally quiescent synoptic regime should limit thunderstorm intensity, however cannot rule out a few strong pulse storms that take advantage of high instability across the interior region. Towards the beginning to middle of next week, winds will gradually veer out of the east, resulting in a slight uptick in temperatures across the region. Expect a few showers and possibly thunderstorms in the morning hours across the east coast, with a gradual westward drift towards the interior again. A much needed reprieve from the oppressive temperatures can be expected through the weekend and into early next week across much of South Florida. Afternoon high temperatures in the mid to upper 80s can be expected along the east coast. Dewpoints will drop to a more manageable 65-68 degrees, allowing for lower apparent temperatures in the upper 80s to low 90s. A gradual warming will take place towards early to middle portions of next week.

&& .AVIATION... (18Z TAFS) Issued at 144 PM EDT Thu May 30 2024 Afternoon showers and storms are developing around the terminals and should linger into the early evening before activity diminishes. An overnight lull in convection will give way to increasing convection around APF on Friday morning. && .MARINE... Issued at 1127 AM EDT Thu May 30 2024 Generally benign boating conditions will continue through the end of the week. By the weekend, wave heights will increase over the Atlantic waters with potential for waves as high as 5 to 6 feet in the presence of a backdoor cold front. Winds may increase out of the east-northeast, up to around 20 kt, this weekend as well. This may prompt a Small Craft Advisory, which will be determined as the time approaches. Aside from this, there is potential for daily showers and thunderstorms, thus resulting in locally elevated winds and seas periodically. && .BEACHES... Issued at 1127 AM EDT Thu May 30 2024 Enhanced easterly flow, in the presence of a departing front, will increase the risk for rip currents this weekend across the Atlantic beaches. As a result, a high risk for rip current could develop across the Atlantic beaches this weekend. && .PRELIMINARY POINT TEMPS/POPS...
