| AMZ600: Synopsis for Jupiter Inlet to Ocean Reef FL out to 60 nm and for East Cape Sable to Bonita Beach FL out to 60 nm 1001 PM EDT Tue Jul 27 2021 Benign marine conditions will occur throughout the rest of the week outside of showers and thunderstorms. Scattered to numerous showers and thunderstorms will be possible across the Atlantic and Gulf waters each day. Expect periods of rough seas and gusty winds in and around any thunderstorm. Gulf Stream Hazards: Winds and waves could be locally higher in and around any shower or thunderstorm. The approximate location of the west wall of the Gulf Stream as of Jul 27, 2021 at 1200 UTC... - 5 nautical miles east of Fowey Rocks. - 12 nautical miles east of Port Everglades. - 13 nautical miles east southeast of Lake Worth. - 9 nautical miles northeast of Jupiter Inlet. |
| Area Forecast Discussion National Weather Service Miami FL 804pm EDT Tuesday July 27 2021 Scattered to numerous showers and thunderstorms will diminsh as the evening progresses. There still could be some localized flooding with the stronger showers and thunderstorms mainly along the east coast for the next several hours. With plenty of moisture remaining in place, scattered to numerous showers and thunderstorms will redevelop on Wednesday as the sea breezes develop and push inland. With steering flow remaining light, storms will once again be slow moving. With heavy downpours, and repeated rounds of heavy rainfall, the potential for localized flooding will remain in place on Wednesday especially in the urban and low lying areas. A few strong thunderstorms cannot be ruled out in the afternoon and evening hours especially over the interior sections. High temperatures on Wednesday will generally range from around 90 across the east coast to the mid 90s over the interior. AVIATION(00Z TAFS)... Outflow boundary driven thunderstorms should persist along the east coast over the next hour or two. Greatest odds for sub-VFR impacts/gusty winds are at KPBI/KFXE/KFLL where TEMPOs are included. Outflow has pushed east of KOPF/KMIA/KTMB so best storm chances should remain east of these airfields. Kept VCTS though through 01z at these locations due to uncertainty. Otherwise generally quiet after ~02z with another round of showers and storms developing ~16-17z tomorrow. Wind speeds and directions should be somewhat erratic early this evening due to numerous outflow boundaries; then becoming light and variable overnight. SE flow returns tomorrow around 08-10 kt for the Atlantic terminals. SHORT TERM (Rest of Today and Wednesday)... Moisture remains across the area with scattered showers and thunderstorms this afternoon. Very light wind profile in the 12Z MFL sounding will cause for slow storm motion once again today. Storms will mainly develop along sea breeze and outflow boundaries this afternoon and evening. A few strong storms cannot be ruled out today with frequent to excessive lightning activity, torrential rainfall combined with slow storm motion which could lead to urban flooding, and gusty winds. Surface high pressure ridge begins to build back in over the Atlantic with the western portion nudging into Central/South Florida with a light southeasterly wind flow. A bit of drier air to the east may help limit some convection overnight or early tomorrow morning. There is TUTT over eastern Cuba that will slowly move across the Keys or southern tip of Florida. This may help enhance the activity over the region tomorrow afternoon. The Atlantic and Gulf sea breezes will develop and push inland in the afternoon leading to scattered to numerous showers and storms. Main impacts will be frequent lightning , heavy rainfall, and strong wind gusts. High temperatures will be in low to mid 90s with heat indices in the triple digits. LONG TERM (Wednesday Night through Tuesday)... Medium-range model guidance remains in good agreement, depicting continental high pressure building over the central CONUS and a subtropical ridge remaining centered over the western Atlantic waters -- with weak mid-level troughing persisting between these air masses. This large-scale pattern will generally support light deep-layer flow and slightly above average moisture content across South Florida, resulting in the daily development of east and west coast sea breeze circulations and scattered thunderstorms each day. A slight southerly component to the low-level flow will tend to focus the highest convective coverage over the interior and lake region, though weak convective inhibition will support the development of new convection along outflow boundaries which will spread into the metro areas during the afternoon and early evening hours. With very light deep-layer flow and ample low/mid- level moisture remaining in place (i.e., PWs of 1.8 to 2.0 in), isolated flooding from slow moving convection will be a concern each day -- especially across vulnerable low-lying metro areas. By this weekend, the above mentioned subtropical ridge will continue building over the western Atlantic waters, while a mid/upper-level inverted trough and accompanying cool mid-level temperatures moves westward along the southern periphery of the ridge toward South Florida. This feature could support a brief uptick in convection across the area for early next week, though plenty of uncertainty remains regarding the details and potential impacts at this time. Temperatures will be near normal each day, with highs in the lower 90s and lows in the middle to upper 70s. AVIATION(18Z TAFS)... Scattered showers and storms this afternoon along the sea breeze convection. Brief MVFR (Marginal Visual Flight Rules) ceilings/vis are possible near and in any afternoon thunderstorms with brief heavy rain and gusty winds. Light and variable winds overnight. Marine Discussion Benign marine conditions throughout the period outside of convection, light to moderate winds. Scattered to numerous showers and thunderstorms will be possible across the Atlantic and Gulf waters each day. Expect periods of rough seas and gusty winds in and around any thunderstorm.
