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
902 AM EDT Sat Aug 8 2020

Broad high pressure will continue to dominate the weather pattern across the coastal waters, keeping light to moderate east to southeasterly flow in place. Seas will generally remain at 2 feet or less across the local waters through early next week. Scattered showers and thunderstorms will be possible each day. Winds and seas could be locally higher in and around any showers or thunderstorms.

Gulf Stream Hazards: Winds and waves could be locally higher in and around showers and thunderstorms.
The approximate location of the west wall of the Gulf Stream as of Aug 06, 2020 at 1200 UTC...
- 10 nautical miles northeast of Fowey Rocks.
- 12 nautical miles southeast of Port Everglades.

Area Forecast Discussion
...UPDATED National Weather Service Miami FL
713am EDT Sat August 8 2020

.Aviation... Like the last few days, convection will begin to develop around midday, generally west of the Atlantic terminals with the better storm chances residing along the Gulf (APF). Otherwise, mostly VFR conditions with light to moderate northeast or easterly flow expected. Light and variable (and dry) conditions expected overnight before much of the same on Sunday.

Discussion... Short Term (Today through Sunday night):

A rather persistent pattern continues to be depicted by model solutions for the short term. A quasi-zonal flow aloft will be in place, while mid level high pressure and surface ridging remain over the northern half of the Florida peninsula. This synoptic scenario will keep pressure gradients fairly relaxed across the area, with mainly light to moderate easterly flow in place. However, sounding data from MFL and model vertical analyses still show PWATs (Precipitable Waters) around 1.8 inches, daytime temps reaching the low-mid 90s, along with returning sea breeze boundaries in the afternoon hours. These three key players should again combine for another round of showers and storms each day.

Best chances for deep convection reside again over interior and west coast areas where the best pool of moisture and B-L instability should reside. But can not rule out a few showers/storms over the Atlantic metro as sea breezes develop, with periods of localized flooding rains and gusty winds. Models also continue to depict a few transient small perturbations moving aloft that may disrupt the zonal flow at times, possibly adding an extra push to any developing strong updraft during the next couple of days.

Expect temperatures to continue to hit the high 80s near the coast, and the mid 90s inland and west coast. And as in previous nights, there will be periods of nighttime mugginess when winds relax.

Long term (Monday - Friday):

Models show a subtropical ridge stretching across the western Atlantic and into the Gulf of Mexico, keeping a persistent light to moderate ESE flow in place. Daytime convection will again be driven by the development and inland migration of sea breeze boundaries. This will continue to favor thunderstorm chances over interior and west coast areas during the afternoon hours. Main thunderstorm hazards will be frequent lightning, heavy rainfall, and the possibility of isolated strong wind gusts.

Models suggest having a little drier air filtering into the area by mid week, potentially cutting back on late week thunderstorm activity. But for now will continue to follow blend guidance for POPs and wait for upcoming model data before deviating from ongoing forecast philosophy.

Temperatures should be near or slightly above normals with afternoon highs in the upper 80s to lower 90s.

Marine... Dominant high pressure across the region will keep generally benign boating conditions in place with light to moderate easterly flow through the period. Only exception will be in the vicinity of thunderstorms, which will bring brief periods of rough seas and gusty winds.
