NWS Miami, FL wrote its last area forecast discussion before the first event at Jul 14, 1:58 PM EST, 3 hours 47 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 258 PM EDT Tue Jul 14 2020 .Discussion... Short Term (Rest of today and Wednesday): A stalled frontal boundary across the Southeast US with high pressure building across the eastern Gulf of Mexico and South Florida. Light wind flow with both sea breezes developing with scattered showers and thunderstorms this afternoon and evening. Storms will develop over the interior and favor the interior and east coast this afternoon. Additional development will be along outflow boundary and sea breeze interactions. Main impacts will be locally heavy rainfall, lightning and an isolated strong wind gust. High pressure continues to build as we move into Wednesday with winds generally beginning to veer becoming northeasterly and easterly. Tomorrow will be the transition day with the changing of the flow pattern. Tomorrow looks similar today with sea breeze driven convection in the afternoon with scattered showers and thunderstorms. The difference will be as we transition to the easterly flow regime storms will generally move away from the east coast and focus towards the interior and west coast. Tomorrow, hot and humid conditions will continue with high temperatures in the low to mid 90s with triple digit heat indices. Until, we can finally get under persistent easterly flow then the higher temps along the east coast will be able to subside. Long Term (Wednesday night through Monday night): Not a lot of changes in the long term scenario. Models show a broad 500mb ridge across the region, while the Atlantic high gradually moves closer to Bermuda during the weekend. This will translate into increasing tropical moisture advection into the sunshine state through early next week. A few nocturnal showers are possible, with a stray storm or two, mainly over the Atlantic coastal waters. Some cells may slowly move over coastal locations each evening. On Thursday, sea breezes will combine with daytime heating to bring another round of afternoon convection, with better chances of rain over the west coast and interior areas as the sea breezes push inland. However, showers should begin to become more widespread across Soflo as the aforementioned tropical moisture advection intensifies. By Friday and into the weekend, a tropical disturbance is shown in the long range models reaching the area and further enhancing the chances for showers and thunderstorms. This disturbance will be slow moving, with model solutions keeping the bulk of the moisture just to the south of the area. Nevertheless, POPs remain in the likely category through early next week, mainly in the afternoon/early evening hours. The NBM continues to struggle in portraying increasing cloud cover and rain activity vs keeping very warm afternoon temps. But since it is long range, the forecast will be adjusted just a little bit cooler than guidance for max temps and wait for upcoming model runs before doing any more significant adjustments. Deep convection should begin tapering off early next week, but with enough leftover low lvl moisture to keep chances of rain in the likely category, at least on Monday. && .Marine... Light wind flow with scattered showers and storms over the local South Florida waters. As high pressure begins to build across the region veering winds to northeast then easterly by the end of the week. Scattered showers and thunderstorms each day, until a tropical wave approaches the region the end of the week into the weekend with increased rain chances. && .Aviation... Both seabreezes have begun to develop and will move towards the interior with additional development in the afternoon and evening. VCTS for all east terminals with TEMPOS for MVFR cigs and vis in storms. Convection will diminsh later this evening with light winds overnight. Both sea breezes develop once tomorrow. && .Preliminary Point Temps/PoPs...
