156 FXUS62 KMFL 160651 AFDMFL Area Forecast Discussion National Weather Service Miami FL 251 AM EDT Fri Aug 16 2024 ...New SHORT TERM, LONG TERM, MARINE, BEACHES... .SHORT TERM... (Today through Saturday) Issued at 250 AM EDT Fri Aug 16 2024 A diffuse boundary has settled over southern Florida which will allow for a focus for tropical moisture today. Precipitable water values well in excess of 2 inches, a pattern conducive to coastal convergence, and recent saturating rainfall across portions of the east coast metro areas could lead to a quick trigger for urban flooding today. Activity could get going at some point this morning with a peak in the afternoon to early evening hours. The boundary will shift south tonight into Sunday, allowing for slightly drier air to move into South Florida. This will help provide some relief from the heat and humidity along with provide for lower shower and thunderstorm chances compared to previous days. && .LONG TERM... (Saturday night through Thursday) Issued at 250 AM EDT Fri Aug 16 2024 The brief relief from the heat for the weekend will start to end as the boundary retreats north from the straits and moisture increases over South Florida early in the week. Another frontal boundary moving across the eastern United States will eventually reach at least Central Florida by mid-week as high pressure builds over the Great Lakes in its wake. This boundary will linger around the peninsula of Florida through much of the week serving as a focus for moisture and returning a more unsettled pattern over the state. && .AVIATION... (06Z TAFS) Issued at 118 AM EDT Fri Aug 16 2024 L/V winds this morning with isolated SHRA across the east coast of South Florida, which could bring periods of MVFR conditions and gusty winds to terminals if directly overhead. SHRA/TSRA activity becomes scattered to widespread this afternoon with light northeasterly surface prevailing across the region. TEMPOs and amendments may be needed as forecast confidence increases. && .MARINE... Issued at 250 AM EDT Fri Aug 16 2024 Winds will shift out of the north-northeast across the local Atlantic waters, and out of the north-northwest across the Gulf waters as a weak surface boundary pushes south across the peninsula. Seas will build into the 3-5 ft range across the Atlantic waters on Friday behind the frontal passage. Isolated-scattered storms will be possible through the period. In and around showers and thunderstorms, locally elevated seas and winds could be realized. && .BEACHES... Issued at 250 AM EDT Fri Aug 16 2024 A persistent easterly wind flow to close out the week and kick off the weekend could allow for an elevated risk of rip currents to develop along the Atlantic beaches of South Florida, particularly in the Palm Beaches. && .PRELIMINARY POINT TEMPS/POPS...
