Area Forecast Discussion National Weather Service Miami FL 721 AM EDT Sat Jul 4 2020

Aviation.

Light winds this morning, with both seabreezes developing this afternoon. Scattered showers and thunderstorms will develop over the interior and move towards the east coast in the afternoon. VCTS for all terminals later this afternoon and evening, except KAPF where by late afternoon development along the Gulf seabreeze should move away from west coast. Convection diminishes after sunset. Light and variable winds once again overnight tonight.

Discussion .

Short term (Today through Sunday night):

Not a lot of changes in the overall synoptic scenario for the short term, at least based on the latest model solutions. Broad high pressure remains in control of the Gulf region, while a weak low is seen on models lingering around the MS/AL coastline. An associated sfc boundary remains semi-stationary, stretching from E TX through the FL panhandle and into the W ATL. Meanwhile, the Atlantic high remains centered east enough from Florida to keep the peninsula under a generally weak southerly flow during the next several days, with periods of winds becoming light or even calm.

Therefore, with the synoptic players described above, expect the weak flow to allow for thermodynamic parameters to become the main driving force behind afternoon showers and thunderstorms. Daytime heating will combine with robust afternoon sea breeze circulations to bring another round of showers and a few storms, favoring interior and east coast locations. POPs are slightly higher for this afternoon as moisture is gradually increasing across SoFlo, but still remaining high-end scattered in nature. Outflow boundary collisions could again keep convection going through the early evening hours. Main concerns with any stronger storms that develop are gusty winds, frequent lightning, small hail, and localized flooding from heavy rainfall.

Afternoon temperatures will continue to run a few degrees above normals, lower to mid 90s across SoFlo. Heat indices will also remain in the 102-108 range, but just shy of advisory criteria.

Long Term (Monday through Friday):

Monday .

Medium-range model guidance generally remains in good agreement -- depicting a quasi-stationary frontal boundary draped across the southeastern CONUS, with a closed mid-level low in the Mid-South vicinity. Present indications are that the western periphery of Atlantic sub-tropical high pressure will be situated slightly to the east of South Florida, gradually building across the region through the period. This synoptic setup will support weak deep-layer southwesterly flow across South Florida, with a belt of slightly enhanced mid-level flow to the north of the area.

Guidance suggests that multiple weak vorticity maxima embedded in the mid-level flow will round the base of the aforementioned mid- level low, facilitating subtle height falls and weak ascent across South Florida. Forecast soundings depict modest mid-level lapse rates for this time of year (near 6.5 C/km) which will support enhanced upward air parcel accelerations in convective updrafts. In addition, abundant moisture (PWs of 1.9 to 2.1 inches) will be available across South Florida, driving strong low-level buoyancy and the potential for deeper convection. The focus for rain showers and thunderstorms should initially be across inland South Florida, generally advecting/propagating eastward towards the Atlantic coast -- where sea-breeze/outflow interactions could lead to locally robust updraft/downdraft development. The mode and intensity of convection that may materialize on Monday is difficult to determine at this time (owing to important mesoscale influences), though the aforementioned favorable thermodynamic parameter space combined with modest kinematic support could support loosely organized convection -- capable of producing strong wind gusts/downbursts, locally heavy rainfall and isolated urban/street flooding, and frequent lightning. Depending on the evolution of the mesoscale environment, small hail could also be a potential convective hazard with the strongest storms that develop.

Tuesday .

By Tuesday, it appears that the aforementioned ridge of high pressure will continue building westward across the region, leading to adiabatic warming throughout the middle/upper troposphere and associated muted upward air parcel accelerations within updrafts. Deep-layer flow/shear will remain weak, with a light easterly low- level component across South Florida. Abundant moisture will remain in place across the area (PWs near 2.0 inches) supporting diurnally- driven sea-breeze convection in the afternoon hours -- primarily focused across inland South Florida and spreading northward and eastward. Strong buoyancy, weak mid-level lapse rates, and unimpressive deep-layer flow/shear should lead to short-lived pulse thunderstorms and disorganized re-development along subsequent outflow boundaries.

Remainder of the week .

The aforementioned mid-level ridge of high pressure should continue building westward across the Gulf of Mexico, leading to light/variable low-level flow and primarily disorganized diurnally-driven convection each afternoon across South Florida. With light deep-layer flow and modest moisture lingering across the area, slow storm motions and efficient warm-rain processes could support a localized heavy rainfall and flooding threat across the metro areas -- especially where persistent mesoscale convergence/ascent becomes established.

Extended global model solutions and their ensemble members depict the aforementioned mid-level low pressure area lifting northeastward towards the Eastern Seaboard as it deepens late in the week. Will have to closely monitor the evolution of the synoptic pattern in the extended period, as this solution could favor a dramatic uptick in convective activity/coverage across South Florida -- owing to enhanced large-scale ascent and deep/rich sub-tropical moisture spreading across South Florida. For now, the extended forecast will rely on a consensus of global ensemble solutions and the National Blend of Models in order to deal with uncertainties in the evolving pattern.

Maximum temperatures should remain slightly above average through the extended forecast period, with lower 90s anticipated across the eastern portions of South Florida, and middle to upper 90s across the interior and western areas. Heat index readings should range from 100 to 109 F each afternoon, with the highest readings expected across southwest Florida.

Marine .

Expect mainly benign boating conditions to continue through the forecast period at all the coastal waters. Only exception will be with any thunderstorm that may form, which will bring brief periods of rough seas and gusty winds.
