429 FXUS62 KMFL 020609 AFDMFL Area Forecast Discussion National Weather Service Miami FL 209 AM EDT Sun Jun 2 2024 ...New SHORT TERM, LONG TERM, MARINE, BEACHES... .SHORT TERM... (Today through Monday) Issued at 205 AM EDT Sun Jun 2 2024 Today, the western Atlantic high will shift eastward, maintaining an easterly synoptic flow over our region. Concurrently, a mid- level shortwave will dip southeast into the area. This approaching shortwave, combined with an increased inland progression of the Gulf breeze, is expected to result in scattered coverage of showers and thunderstorms. With the easterly flow, morning and early afternoon convection will likely be concentrated near the east coast, while stronger and more widespread activity will occur in the mid to late afternoon over Southwest Florida (SWFL) and the interior. High temperatures will follow a typical easterly regime, ranging from the mid-80s near the immediate east coast to the low to mid-90s over the interior and SWFL. A mid-level trough will traverse the region to conclude the weekend and start the workweek on Monday. This will bring increased moisture and the potential for showers and thunderstorms beyond the usual diurnal pattern. Bouts of convection may spawn off of the Atlantic waters and South Florida - primarily the east coast. This could lead to impressive rainfall accumulations during short periods of time, with ponding of roadways possibly being a concern across urban locations. && .LONG TERM... (Monday night through Saturday) Issued at 205 AM EDT Sun Jun 2 2024 By Tuesday, the trough axis will exit into the Atlantic waters, allowing the weather pattern to revert to a more diurnally-driven regime. Morning showers over the Atlantic will transition into inland and Gulf coast showers and thunderstorms by the afternoon and early evening. A few strong thunderstorms cannot be ruled out through this period, particularly over areas where steepened lapse rates juxtaposes pockets of enhanced low-level convergence. The surface high will linger around the region through midweek before the next frontal boundary, originating from low pressure over Canada, enters the southeastern United States. The parent low will move southeastward over the Great Lakes by late in the week. South Florida will be positioned between the stalled frontal boundary near Interstate 10 and deeper tropical moisture in the western Caribbean. The retrogression of the surface high back into the Atlantic will shift the flow to southerly to west- southwesterly across much of the area. This may prove to be a ripe environment for intermittent periods of showers and thunderstorms, with the most likely timeframe for development being in the afternoon during peak heating. The warm airmass combined with this flow over the peninsula will lead to a significant warming trend throughout the week, potentially increasing the risk of heat-related illnesses by late week. This situation will need to be monitored closely, along with the progress of the synoptic scale features both to the north and south, as changes could necessitate major revisions to the forecast. For now, hot and diurnally unsettled weather is expected for a good part of the week. && .AVIATION... (06Z TAFS) Issued at 103 AM EDT Sun Jun 2 2024 Scattered showers and thunderstorms throughout the period, especially across the east coast locations. Some stronger storms may result in brief IFR ceilings and visbys. Easterly winds 10-15 kts with gusts of 20-25 kts this afternoon into early evening. && .MARINE... Issued at 205 AM EDT Sun Jun 2 2024 Fresh to strong east-northeast winds will gradually diminish in strength below Small Craft Advisory criteria through this morning. Seas will also continue to decrease to below 5 feet by Sunday. Showers and thunderstorms, especially in the evening and overnight periods, will remain possible over the next few days. && .BEACHES... Issued at 205 AM EDT Sun Jun 2 2024 Breezy easterly winds will result in a high risk of rip currents for the east coast beaches through Sunday. This risk will begin to decrease this upcoming week as the easterly flow diminishes. && .PRELIMINARY POINT TEMPS/POPS...
