Synopsis.. High pressure ridge over south florida will keep benign marine conditions through the rest of the week and the upcoming weekend, outside of showers and Thunderstorms. Scattered showers and Thunderstorms are 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 29, 2021 at 1200 utc... 11 nautical miles east of fowey rocks. 21 nautical miles east southeast of port everglades. 18 nautical miles east of lake worth. 13 nautical miles east of jupiter inlet.

Area Forecast Discussion National Weather Service Miami FL 1005 AM EDT Thu Jul 29 2021
. Thunderstorms with Locally Heavy Rainfall and Flooding Possible This Afternoon .
UPDATE. Surface and low level ridge has nudged northward over the past 24 hours, now located right over the southernmost part of the peninsula. The 12z Miami sounding reflects this with 0-3 km mean wind SSE at 4 knots compared with the west wind of the past two days. In the mid and upper levels, a weak trough extends northward across our area from the cyclonic circulation over western Cuba. Moisture levels remain virtually unchanged with precipitable water value from the Miami sounding of 1.84 inches, and near 2 inches across most of South Florida based on TPW data from GOES-16.
Weak forcing provided by the mid/upper trough along with good morning insolation/instability will aid in the development of showers and thunderstorms over the peninsula, starting later this morning over the east coast metro areas (earlier than past days), around midday along the Gulf coast seabreeze front, then eventually concentrate over the interior by mid-afternoon. Increased rain chances some for today over the interior and east coast metro areas in accordance with the short range guidance and pattern described above, with highest PoPs over the Everglades and Lake Okeechobee areas.
Localized rain amounts in excess of 2" have been observed each of the past few days, and today should be no different due to the slow storm motion. In fact, there may be a slightly higher chance of localized flooding than previous days due to the S-SW storm motion paralleling the sea breeze boundaries and helping to propagate and back-build storms along the boundaries. The marginal excessive rain risk by the Weather Prediction Center for today is certainly in play, and the metro areas along both coasts continue with the higher threat (more so Atlantic coast vs. Gulf).
PREV DISCUSSION. (Issued 803 AM EDT Thu Jul 29 2021)
AVIATION(12Z TAFS) . Showers and thunderstorms are expected to form near the SE Florida terminals around 14z and continue through about 20z-22z. Coverage should be scattered enough for VCTS with TEMPO MVFR ceilings to cover this scenario, with possible amendments for any cells that develop or move over a terminal. At KAPF, VCTS after 16z is in effect to cover storms forming along the Gulf seabreeze. Light/variable winds, with sea breezes 8-10 knots predominating after 15z.
PREV DISCUSSION . (Issued 357 AM EDT Thu Jul 29 2021)
Another warm, wet day in store for South Florida.
SHORT TERM (Today through Friday) . The warm, wet pattern continues across South Florida as a tropical upper tropospheric trough (TUTT) departs the region today. The TUTT is centered between Key West and Cuba this morning as it continues westward towards the Gulf of Mexico. Some convection is firing along the eastern fringes of the TUTT which could make their way westward through the morning across the Atlantic waters towards South Florida. At the surface, the ridge axis remains over the southern peninsula of Florida which is creating a very light wind flow pattern that will largely be dominated by any sea and lake breezes that develop.
The environment will still be ripe for showers and thunderstorms today, particularly inland where boundary collisions later today will be more numerous. Sufficient moisture and available instability thanks to diurnal heating should permit decent coverage of convection again today. Behind the TUTT, some relatively drier air and subsidence could help create a lull in convection tonight. To the north, a weakening trough will slide southward into south central Florida becoming more diffuse through the day on Friday. This will help keep showers and storms in the forecast on Friday with a focus for convection over northern portions of the area around Lake Okeechobee.
Temperatures both days will reach the lower to mid 90s for highs with heat index values in the triple digits. Strong thunderstorms capable of producing frequent to excessive lightning, heavy rainfall which could lead to localized flooding, and strong wind gusts are possible both days. Cannot rule out waterspout activity over the local waters and funnel clouds with any boundary interactions on either day as well.
LONG TERM (Friday Night through Wednesday) . A ridge of high pressure extending over South Florida from the Atlantic will be pinched by a weak trough sitting just north of the area. Aloft, the supporting trough axis shifts north and east away from the region which will allow for the surface ridge to gain some mid-level component and slide slightly northward. With this northward axis movement, a more southerly flow will become established heading into next week though the light flow will permit an onshore component along each coast with sea breeze development most days. Temperatures will remain warm with lower to mid 90s for highs and heat index values in the upper 90s to triple digits. Shower and thunderstorm chances will remain at least close to climatological averages though shifts in available moisture could impact PoPs from day to day, particularly in the extended period of the forecast.
MARINE . Light wind and the lack of any major surface low pressure in the region should keep seas 2 feet or less outside of locally higher waves due to showers and thunderstorms through most of the week. Waterspouts are also possible across all the South Florida waters today.
